Velopharyngeal valve closure is essential for adequate speech intelligibility as well as for other activities. The variations in the contribution of different components of the velopharyngeal port walls produce different closure patterns. The aim of this cross-sectional study is to identify the prevalence of the different velopharyngeal closure patterns in Arabic-speaking individuals with no perceived hypernasality or velopharyngeal dysfunction.After verification of selection criteria, 100 subjects with age range between 15 and 60 years underwent nasoendoscopic examination and both the extent of movement of the different velopharyngeal walls as well as closure pattern were observed.Almost all participants had grade 4 (full range) velar mobility, most participants had grade 3 lateral pharyngeal wall movement, and none showed any observable posterior pharyngeal wall movement. Coronal closure pattern was the most frequent (75%) among participants followed by circular pattern (25%). There was no statistically significant difference between both genders in the extent of velar and lateral pharyngeal wall movements, yet the frequency of closure patterns differed statistically significantly between males and females.Coronal pattern was the most prevalent type of velopharyngeal closure in subjects with normal habitual resonance, of both sexes, yet it occurred more frequently in males.

Objective: Comparison of speech outcomes in 2 similar groups of "wide" cleft palate. One received a Furlow double-opposing Z- plasty (FZP) versus a group (non-FZP) that received only a muscle release at the second stage after both received a soft palate mucosal adhesion (SPA) at the first stage. Methods: Retrospective review. Thirty-three patients (non-FZP) versus 29 patients (FZP) between 2010 and 2016. Both groups had SPA at approximately 6 months of age. After 12 months, an FZP with hard palate closure was performed in the FZP group. in the non-FZP group, only the muscle was released from the posterior palatal shelves with hard palate closure. Speech and velopharyngeal insufficiency (VPi) were determined clinically and by videofluoroscopy. Results: The FZP group (15 M: 14 F) with Veau (III = 14; IV = 5; II = 10) had a mean palate length (MPL) of 20.5 mm and mean palate width (MPW) of 11.2 mm at 8.3 months. MPW decreased to 7 mm after 20.7 months. 21% (n = 6) had fistulae. 14% (n = 4) (all males) had VPI. Their MPL was 16.3 mm. The mean follow-up was 5.5 years. In the non-FZP group, (18 M: 15 F) with Veau (III = 22; IV = 7; II = 4), the MPL was 20.5 mm and MPW was 11 mm at 8.4 months. MPW decreased to 6.5 mm after 12.5 months (P = 0.006). The fistula rate was 18% (n = 6). 24% (n = 8) predominantly male (87%) had VPI (P = 0.432). Their MPL was 17 mm; the mean follow-up was 4.7 years. Conclusions: SPA as a first stage performed in "wide"Â ™ cleft palate narrows the subsequent hard palate repair and with a muscle release, may be adequate in some patients.

Velopharyngeal insufficiency (VPI), a stigmatizing hallmark of palatal dysfunction, occurs in a wide spectrum of pediatric craniofacial conditions. The mainstays for surgical correction include palate repair and/or pharyngeal surgery. However, primary pharyngoplasty has a failure rate of 15% to 20%. Although revision pharyngoplasty may be necessary in those with persistent VPI, little is known regarding the indications for and outcomes after such procedures. The purpose of this study is to describe the authors' experience with indications for and outcomes after revision pharyngoplasty.A single-center retrospective review was performed of all patients undergoing revision pharyngoplasty between 2002 and 2019. Demographic data and Pittsburgh Weighted Speech Scores, diagnoses, comorbidities, and complications were tabulated. Two-tailed Student t test was used, and a P value of 0.05 or less was considered statistically significant.Thirty-two patients (65.6% male) met inclusion criteria for this study. The most common diagnoses included cleft palate (68.8%), submucous cleft palate (SMCP, 18.8%), and congenital VPI (6.3%, likely occult SMCP). Most patients (84.4%) underwent palatoplasty before their initial pharyngoplasty. The primary indication for initial pharyngoplasty was VPI (mean age 7.1 ± 4.6 years). The most common indication for revision pharyngoplasty (mean age 11.2 ± 5.1 years) included persistent VPI (n = 22), followed by obstructive sleep apnea (OSA) (n = 11). Persistent VPI (n = 8) and OSA (n = 6) were the most common complications after secondary pharyngoplasty. Thirteen patients (40.6%) within the revision pharyngoplasty cohort required additional surgical intervention: 4 underwent tertiary pharyngoplasty, 4 underwent takedown for OSA (n = 3) or persistent VPI (n = 1), 3 underwent takedown and conversion Furlow for persistent VPI (n = 2), OSA (n = 2) and/or flap dehiscence (n = 1), and 2 underwent palatal lengthening with buccal myomucosal flaps for persistent VPI. Of the 4 patients who required a tertiary pharyngoplasty, the mean age at repair was 6.6 ± 1.1 years and their speech scores improved from 13.5 to 2.3 after tertiary pharyngoplasty (P = 0.11). The overall speech score after completion of all procedures improved significantly from 19 to 3.3.Patients who fail primary pharyngoplasty represent a challenging population. Of patients who underwent secondary pharyngoplasty, nearly half required a tertiary procedure to achieve acceptable speech scores or resolve complications.

Introduction: Individuals with cleft palate can present with velopharyngeal dysfunction after primary palatoplasty and require a secondary treatment due to insufficiency. In these cases, the pharyngeal bulb prosthesis can be used temporarily while awaiting secondary surgery. Objective: This study aimed to investigate the outcome of treatment of hypernasality with pharyngeal bulb prosthesis in patients with history of cleft palate presenting with velopharyngeal insufficiency after primary palatal surgery. We hypothesized that the use of the pharyngeal bulb prosthesis is an effective approach to eliminate hypernasality related to velopharyngeal insufficiency in patients with cleft palate. Methods: Thirty speakers of Brazilian Portuguese (15 males and 15 females) with operated cleft palate, ages ranging from 6 to 14 years (mean: 9 years; SD = 1.87 years), participated in the study. All patients were fitted with a pharyngeal bulb prosthesis to manage velopharyngeal insufficiency while they were awaiting corrective surgery to be scheduled. Auditory-perceptual analysis of speech recorded in the conditions with and without pharyngeal bulb prosthesis were obtained from three listeners who rated the presence or absence of hypernasality for this study. Results: Seventy percent of the patients eliminated hypernasality while employing the pharyngeal bulb prosthesis, while 30% still presented with hypernasality. The comparison was statistically significant (p < 0.001). Conclusion: The use of the pharyngeal bulb prosthesis is an effective approach to eliminate hypernasality related to velopharyngeal insufficiency. Resumo Introdução: Indivíduos com fissura palatina podem apresentar disfunção velofaríngea após a palatoplastia primária e necessitam de um secundário devido à insuficiência velofaríngea. Nesses casos, o obturador faríngeo pode ser usado temporariamente enquanto se aguarda uma cirurgia secundária. Objetivo: Investigar o resultado do tratamento da hipernasalidade com o uso de obturador faríngeo em pacientes com histórico de fissura palatina que apresentam insuficiência velofaríngea após a palatoplastia primária. Nossa hipótese é que o uso do obturador faríngeo seja uma abordagem eficaz para eliminar a hipernasalidade relacionada à insuficiência velofaríngea em pacientes com fissura palatina Método: Participaram do estudo 30 indivíduos falantes do Português Brasileiro (15 homens e 15 mulheres) com fissura palatina operada, de 6 a 14 anos de idade (média: 9 anos; DP = 1,87 anos). Todos os pacientes receberam obturador faríngeo para o tratamento da insuficiência velofaríngea, enquanto aguardavam vaga para a cirurgia secundária. A análise perceptivo-auditiva da fala, realizada nas condições com e sem obturador faríngeo, foi realizada por três ouvintes, quanto à presença e ausência da hipernasalidade. Resultados: 70% dos pacientes eliminaram a hipernasalidade de fala com o uso do obturador faríngeo, enquanto 30% não eliminaram. A comparação foi estatisticamente significante (p < 0,001). Conclusão: O uso temporário do obturador faríngeo é uma abordagem efetiva para eliminar a hipernasalidade decorrente da insuficiência velofaríngea.

Purpose Persistent velopharyngeal insufficiency (VPI) following primary palatoplasty remains a difficult problem to treat. This study evaluates speech outcomes following revision palatoplasty with tissue augmentation using buccal myomucosal flaps (BMF) as an alternative to pharyngoplasty for patients with VPI. Methods A retrospective single-center review of revision palatoplasty with tissue augmentation at a tertiary pediatric hospital Cleft-Craniofacial Center between January 2017 and March 2021 was conducted. Patients with a history of previous palatoplasty, a diagnosis of persistent or recurrent VPI, and comprehensive pre- and postoperative speech evaluations who underwent revision palatoplasty with BMF were included. Results Twenty patients met inclusion criteria (35% female, 20% syndromic). Mean age at the time of revision palatoplasty with BMF was 9.7 years. Preoperatively, all patients had stigmatizing speech and received the recommendation for speech surgery; the mean Pittsburgh Weighted Speech Score (PWSS) was 14.3 ± 4.9. The mean postoperative PWSS at the most recent assessment was 4.2 ± 2.3, representing a statistically significant improvement from preoperative scores ( P Conclusion In patients with VPI following primary palatoplasty, revision palatoplasty with tissue augmentation offers an alternative to pharyngoplasty. This approach preserves dynamic velopharyngeal function, improves speech outcomes, and should be considered an option when treating patients with post-primary palatoplasty VPI.

Purpose: This study investigated the practice patterns of private community speech-language pathologists (SLPs) when treating children with a repaired cleft of the palate with or without a cleft of the lip (CP ± L). Practices were explored in terms of diagnostics and treatment focus, treatment dosage and experienced difficulties when treating children with a CP ± L.Method: Eleven female private community SLPs, who lived in Flanders (i.e. the northern part of Belgium) and were aged between 23 and 62 years participated in this study. Data were collected from semi-structured face-to-face interviews. The qualitative software program NVivo 12 was used for data analysis. The interviews were analysed using an inductive thematic approach.Result: SLPs reported a lack of available information on speech-related cleft care. SLPs expressed the need to receive a referral letter from the hospital in order to make an adequate speech diagnosis. Most therapists reported that they performed an articulatory assessment combined with a language assessment. Most SLPs used a hybrid treatment model including a variety of intervention techniques. These techniques were not always in line with available scientific evidence. SLPs reported the desire to receive practical step-by-step guidelines on how to provide speech intervention to children with a CP ± L. In contrast, there was a strong consensus among the therapists that an individualised treatment plan is necessary.Conclusion: The results of this study have revealed gaps in the dissemination and implementation of scientific evidence relevant to speech services for children with a CP ± L (i.e. a research-practice gap) in Flanders. Research evidence needs to be adequately translated into clinical practice by providing concrete and practical guidelines.

Objective The study aims to evaluate posterior pharyngeal wall augmentation using autologous tragal cartilage graft in adults with velopharyngeal valve insufficiency (VPI). Methods The study included 23 patients with VPI (grade I, II, III), with ages ranging from 19 to 45 years. Six patients had previously undergone simple palatoplasty for cleft palate, 8 patients had previously undergone adenotonsillectomy and 9 patients had previously undergone uvulopalatopharyngoplasty (UPPP). The procedure was done by implanting a piece of autologous tragal cartilage in the posterior pharyngeal wall. Patients were followed up for 24 months postoperatively. The evaluation of percent of speech intelligibility and grade of the closure of the velopharyngeal valve using video-nasopharyngoscopy was evaluated preoperatively and postoperatively. Results Highly statistically significant improvement in the grade of the closure of the velopharyngeal valve (P = 0.009) and percent of intelligibility (P = 0.001) was found after surgery. There were no postoperative airway obstruction or sleep apnea. Conclusion Augmentation of the posterior pharyngeal wall using tragal cartilage is an effective, safe and physiological surgical procedure in the management of VPI in adults who suffered hypernasality following palatal and oropharyngeal surgeries.

Background The authors present outcomes analysis of the nasoalveolar molding treatment protocol in patients with a cleft followed from birth to facial maturity. Methods A single-institution retrospective review was conducted of cleft patients who underwent nasoalveolar molding between 1990 and 2000. Collected data included surgical and orthodontic outcomes and incidence of gingivoperiosteoplasty, alveolar bone grafting, surgery for velopharyngeal insufficiency, palatal fistula repair, orthognathic surgery, nose and/or lip revision, and facial growth. Results One hundred seven patients met inclusion criteria (69 with unilateral and 38 with bilateral cleft lip and palate). Eighty-five percent (91 of 107) underwent gingivoperiosteoplasty (unilateral: 78 percent, 54 of 69; bilateral: 97 percent, 37 of 38). Of those patients, 57 percent (52 of 91) did not require alveolar bone grafting (unilateral: 59 percent, 32 of 54; bilateral: 54 percent, 20 of 37). Twelve percent (13 of 107) of all study patients underwent revision surgery to the lip and/or nose before facial maturity (unilateral: 9 percent, six of 69; bilateral: 18 percent, seven of 38). Nineteen percent (20 of 107) did not require a revision surgery, alveolar bone grafting, or orthognathic surgery (unilateral: 20 percent, 14 of 69; bilateral: 16 percent, six of 38). Cephalometric analysis was performed on all patients with unilateral cleft lip and palate. No significant statistical difference was found in maxillary position or facial proportion. Average age at last follow-up was 20 years (range, 15 years 4 months to 26 years 10 months). Conclusions Nasoalveolar molding demonstrates a low rate of soft-tissue revision and alveolar bone grafting, and a low number of total operations per patient from birth to facial maturity. Facial growth analysis at facial maturity in patients who underwent gingivoperiosteoplasty and nasoalveolar molding suggests that this proposal may not hinder midface growth. Clinical question/level of evidence Therapeutic, IV.

Background Pierre Robin sequence (Robin sequence) is defined as the triad of micrognathia, glossoptosis, and airway obstruction. It is frequently associated with palatal clefting. In recent years, increased interest in speech outcomes of cleft patients diagnosed with Robin sequence has been shown. Methods Speech outcomes of cleft patients with Robin sequence were assessed at age 5 in comparison with a cleft palate-only cohort. Speech parameters were evaluated according to the Cleft Audit Protocol for Speech-Augmented and analyzed using the National Audit Standards for Speech (United Kingdom). All patients were treated in the same institution during the same period (2005 to 2012). Subjects who needed nasopharyngeal airway support and those whose airway was managed by positioning only were eligible. Results Fifty-one cleft patients diagnosed with Robin sequence were included in this study. Outcomes were compared to those of 128 nonsyndromic cleft palate-only patients.Patients with Robin sequence were shown to present with a significantly higher rate of cleft speech characteristics in comparison to the reference cohort (p = 0.001). Furthermore, it was shown that Robin sequence is associated with a significantly higher rate of secondary speech surgery for velopharyngeal dysfunction before the age of 5 (p = 0.016). Robin sequence patients with a nasopharyngeal airway presented with a higher rate of cleft speech characteristics compared to Robin sequence patients managed with positioning only. Conclusion Cleft patients with Robin sequence are more likely to need further surgery to correct velopharyngeal dysfunction before the age of 5 and are more prone to present with cleft speech characteristics at the age of 5. Clinical question/level of evidence Risk, II.

The aim of this retrospective study was to evaluate results of four different surgical approaches to palatoplasty and to demonstrate which type showed the lowest number of cases with the need for secondary surgeries. The results of 227 patients who underwent cleft palate surgical repair over a 13-year period (2000-2012) were included. The incidence rates of oronasal fistula, velopharyngeal insufficiency with the need of pharyngeal flap and pharyngoplasty were examined. The need for revision surgery was found in 48 patients (21.1 %). A significantly higher rate of cases with the need for secondary correction was found in patients with a complete cleft (44 %) as compared to patients with incomplete cleft palate (9.8 %). A higher percentage for additional surgery was noted after the Bardach procedure (50 %) as opposed to the lower revision rate after Veau-Wardill-Kilner (22.8 %) and Furlow (17.6 %). After the von Langenbeck procedure, the need for revision eventuated only in 5.5 % of cases. It is important to mention that there were no significant differences in the incidence of secondary surgery between the patients with cleft palate with or without the presence of Pierre Robin sequence. Neither there was observed a significant difference in the incidence of additional surgery between male and female patients. However, a higher need for pharyngeal flap was noted in the female group (Tab. 8, Ref. 38). Keywords: complications after palatoplasty, cleft repair techniques, Pierre Robin sequence, pharyngeal flap.

Introduction Van der Woude syndrome (VWS), an autosomal dominant condition associated with clefts of the lip and/or palate and lower lip pits, is caused by mutations in interferon regulatory factor 6 gene. It is reported to be the most common syndromic cleft worldwide. This case series presents the phenotypic characteristics and treatment outcomes in a group of 9 patients diagnosed with VWS. Methods A retrospective review was performed on records of patients given a diagnosis of VWS presenting to the Department of Plastic Surgery of Sohag University between July 2009 and November 2019. Data analyses included age and sex of affected patients, type of the cleft, associated anomalies, presence of lower lip pits, and history of lower lip pits/cleft in the family and treatment outcomes. Results The study identified 9 patients (male = 2, female = 7). Age at first presentation ranged between 1 week and 7 years (mean = 1.3 years). Four patients had bilateral cleft lip and palate and 1 patient had unilateral cleft lip and palate (UCLP), whereas 4 patients had isolated cleft palate. Bilateral lower lip pits were presented in 8 patients, whereas the ninth patient has unilateral pit. Family history was positive in 3 patients. Most patients in this study developed after palatal repair speech problems with an increased rate of secondary surgical procedures needed for correction of velopharyngeal insufficiency. Conclusions All reviewed cases of VWS presented with lower lip pits and cleft palate with or without cleft lip. A positive family history of similar conditions was demonstrated in 33.3% of our patients. This study suggests an increased incidence of secondary palatal surgeries for velopharyngeal insufficiency in patients with VWS; this warrant further studies including control group of nonsyndromic cleft patients.

Background Although most patients attain normal speech after cleft palate repair, up to 20 percent require secondary speech surgery. Despite the frequency of these procedures, complications and rates of subsequent revisions of secondary speech surgery after all procedure types have never been reviewed using national, longitudinal data. Methods The authors examined insurance claims from Clinformatics Data Mart between 2001 and 2017. Cases were categorized as palatalprocedures (i.e., palatoplasty, revision palatoplasty, secondary lengthening, palatal island flap) or pharyngeal procedures (i.e., pharyngeal flap, dynamic sphincter pharyngoplasty) (n = 846). Continuous enrollment from 180 days before to 30 days after surgery was required. Patients were excluded if they underwent palatoplasty, or any surgery at less than 3 years of age, without a speech diagnosis. Outcomes included 30-day complications and rates of subsequent revision secondary speech surgery. Multivariable logistic regression was used to evaluate the relationship between procedure type and complications. Results In this cohort, 52.5 percent underwent pharyngeal procedures, and 47.5 percent underwent palatal procedures. Complications occurred in 10.9 percent of patients and included respiratory complications (4.0 percent), bleeding (1.2 percent), dehiscence (3.6 percent), and critical care episodes (3.0 percent). There was no difference in complications between procedure types (OR, 0.87; 95 percent CI, 0.56 to 1.37; p = 0.56). The subsequent revision rate was 12.7 percent, but was 21.7 percent in patients with 3 years of postoperative enrollment. Conclusions Although complication rates were comparable to those in recent literature, rates of subsequent revisions of secondary speech procedures were high in patients with longer postoperative enrollment. Thus, these patients merit prolonged follow-up, as velopharyngeal dysfunction may recur over time. Clinical question/level of evidence Therapeutic, III.

Objectives: To describe a case of coincident Castleman’s disease and myasthenia gravis that initially presented as rapidly progressive dysphagia and dysphonia and to review the unique pathophysiology of these two uncommon diagnoses. Methods: Case report and literature review. Results: Castleman’s disease, angiofollicular or giant lymph node hyperplasia, is a rare benign lymphoid proliferation. Traditionally, the disease is classified based on histologic and clinical characteristics. Fewer than 10 cases with concurrent myasthenia gravis have been reported. Myasthenia gravis and thymic epithelial tumors are both associated with acetylcholine receptor antibody. While patients with isolated Castleman’s disease are usually asymptomatic, those who have concurrent myasthenia gravis and undergo surgical treatment are at increased risk of postoperative myasthenic crisis. Both pre- and postoperative plasmapheresis are suggested to improve muscle strength and prevent severe postoperative complications. Conclusions: In the setting of multiple cranial neuropathies including velopalatal insufficiency and bilateral ptosis it is important to consider myasthenia gravis. Castleman’s disease occurs rarely in conjunction with myasthenia gravis but may increase the risk of myasthenic crisis.

Purpose This study aims to attain metric data of the velopharyngeal dimensions of healthy subjects as well as patients with velopharyngeal insufficiency using the example of cleft and lip palate (CLP) in order to determine possible differences in the volumes of both groups. Methods Volumes and distances of velopharyngeal areas were analyzed retrospectively using cone beam computed tomography data sets (n = 60). Group 1 included healthy patients receiving dental implants (n = 31). Group 2 was represented by patients with surgically closed cleft lip and palate (n = 29). Results Biggest differences among mean values of both groups were found for: minimum axial area (p = 0.000), airway area caudal (p = 0.000), distance between posterior nasal spine and posterior pharyngeal wall (PPW) (p = 0.014), mean distance between velum and PPW (p = 0.000), length of PPW (p = 0.000) and length of anterior pharyngeal wall (p = 0.000). Conclusion Differences in the shape and geometry of the velopharyngeal area in subjects with a regular velopharyngeal structure and function and patients with cleft palate do exist. The significant differences found here can be categorized into two groups: one reflects distances between the anterior and posterior pharynx, presenting longer distances for patients with CLP. The second significant difference regards values of length in cranio-caudal direction, which is longer in healthy subjects. With regards to these values, one could conclude, that even though total volumes of both groups did not differ in size, group 1 shows three-dimensional velopharyngeal shapes that are longer and narrower, whereas shapes of patients of group 2 tend to be wider and shorter in general.

Submucous cleft palate (SMCP) is a congenital condition related to abnormal muscle attachments within the soft palate. Even though hypernasality and nasal emission, the primary symptom of SMCP, have been well-documented, research on articulation errors is currently lacking. The object of this study was to examine the consonant articulation in patients with unoperated SMCP and its possible correlation with the velopharyngeal function. This study analyzed the perceptual speech assessment and nasopharyngoscopy data of 338 patients with unoperated SMCP between years 2008 and 2016 retrospectively. The mean age of the patients was 13.27 years. About 125 patients showed velopharyngeal competence (VPC), 174 velopharyngeal incompetence (VPI), and 39 marginal VPI (MVPI). Among the 338 patients, 137 presented normal articulation, 124 consonant omission, 25 compensatory articulation, 36 consonant weakening, 51 consonant substitution, and 36 posterior placement. About 70.40% VPC patients, 17.24% VPI patients, and 48.72% MVPI patients demonstrated normal articulation. About 59.20% VPI patients showed consonant omission. The results demonstrated that consonant articulation varied among patients with unoperated SMCP and was correlated with their velopharyngeal functions, while consonant omission was the most common articulation error. Velopharyngeal closure pattern was not associated with either velopharyngeal function or consonant articulation.

Background This study aims to outline the 30-d complications of different velopharyngeal insufficiency (VPI) correction techniques using the American College of Surgeons National Surgical Quality Improvement Program-Pediatric. Methods Using the American College of Surgeons National Surgical Quality Improvement Program-Pediatric, VPI cases from 2012 to 2015 were identified. Patients were subdivided into two cohorts: (1) palatal procedures and (2) pharyngeal procedures, with the latter being subdivided into (1) pharyngeal flap and (2) sphincter pharyngoplasty. Patient characteristics and postoperative outcomes were compared using Pearson's chi-squared or Fischer's exact test for categorical variables and independent t-tests, Wilcoxon-Mann-Whitney, or analysis of variance for continuous variables. Results: A total of 767 VPI cases were identified: 191 (24.9%) treated with palatal procedures and 576 (75.1%) with pharyngeal procedures, of which 444 were pharyngeal flap and 132 were sphincter pharyngoplasty. Patients who underwent palatal procedure had longer anesthesia (152.41 min) and operating time (105.72 min), whereas patients who underwent pharyngeal procedure had longer length of stay (1.66 d). There were no significant differences in outcomes between the two groups, nor were there significant differences in outcomes between pharyngeal flap and sphincter pharyngoplasty subgroups. Patients who experienced complications were younger, shorter, inpatient, and having a shorter operation time, longer anesthesia time, or longer length of stay. Plastic surgeons performed the majority of palatal procedures (62.3%), whereas pharyngeal procedures were most often performed by otolaryngologists (48.8%). Conclusions: As per national data, both palatal and pharyngeal procedures for repair can be performed with comparable 30-d complications. The chosen technique may be based on patient presentation and on the surgeon comfort level.

No consensus exists on the selection of procedures for the treatment of submucous cleft palate, with scarce reports on long-term outcomes from single-surgeon experience. This study assessed the outcomes of using extended indication criteria of Furlow palatoplasty as the first-line procedure for the management of submucous cleft palate-associated velopharyngeal insufficiency.Consecutive nonsyndromic patients with submucous cleft palate (n = 216) treated by a single surgeon between 1998 and 2018 were reviewed. Furlow palatoplasty was performed in all patients diagnosed with submucous cleft palate-associated velopharyngeal insufficiency, regardless of the age cutoff, number of Calnan triad features, or velopharyngeal gap size and pattern. Postoperative velopharyngeal function outcome (adequate, marginal, or inadequate) and the need for secondary surgery were investigated. Age at surgery, sex, submucous cleft palate type (classic and occult), and presence of complication were evaluated for potential associations with this outcome.Forty-seven patients aged 8.3 ± 4.6 years with occult submucous cleft palate were significantly (p0.001) older than those with the classic type (n = 169; 5.6 ± 3.1 years). Most (p0.001) of the included patients [n = 181 (83.8 percent)] achieved adequate postoperative velopharyngeal function outcome. Three patients (1.4 percent) presented surgery-related complications, including bleeding and partial wound disruption. Secondary speech surgery was recommended in 24 patients (11.1 percent). In the bivariate and multivariate analyses, none of the tested variables was found to be associated (all p0.05) with the postoperative velopharyngeal function outcome.The extended indication criteria of Furlow palatoplasty provided adequate velopharyngeal insufficiency management with a low complication rate and satisfactory speech outcome.Risk, III.

Velopharyngeal insufficiency (VPI) impacts resonance and articulation and contributes to social difficulties. Nasopharngoscopies (NPs) often inform VPI treatment planning. Using a mixed-model prospective design, this study describes the impact of VPI, NP perceptions, and ratings of pain, discomfort, and cooperation during NP from multiple perspectives. Participants (N = 33) were 7 to 16 years old (mean 8.8 years) with diagnoses primarily of cleft lip and palate (52%) or cleft palate (42%). Mostly mothers (82%) completed measures in English (58%). Patients (52%) reported some teasing related to VPI, with higher parent report of their child being teased (70%). Themes of not being understood, teasing, and negative emotions were described. Coping themes included social support, distraction, and speech therapy. Patients' Beck Youth Inventories-Second Edition scores were in the average range. Over half of patients and parents reported anxiety about NPs and about a third reported understanding NPs. The Faces Pain Scale-Revised mean of 2.5 ± 3.2 and the Face, Legs, Activity, Cry, Consolability scale mean of 2.5 ± 2.2 were low. Discomfort was most often rated as "a little" by patients (55%), parents (42%), speech-language pathologists (49%), and plastic surgeons (39%). There was concordance across pain and discomfort ratings. High cooperation (61%-72%) was seen across reporters, which was negatively correlated with pain measures. Patient anxiety was related to NP pain and discomfort, suggesting integrating coping for procedural anxiety into the NP preparation might benefit patients. Additionally, negative VPI social experiences should be screened for as part of VPI management.

BackgroundVelopharyngeal insufficiency is the inability to close the velopharyngeal port during speech and swallowing, leading to hypernasal speech and food regurgitation.ObjectiveThis study aimed to explore the aetiological factors contributing to the development of velopharyngeal insufficiency in a non-cleft paediatric population, especially following adenoidectomy.MethodsA retrospective case review was conducted of all children without a known cleft palate, born between 2000 and 2013, who were referred to a tertiary cleft centre with possible velopharyngeal insufficiency.ResultsThe data for 139 children diagnosed with velopharyngeal insufficiency following referral to the cleft centre were analysed. Thirteen patients developed the condition following adenoidectomy; only 3 of these 13 had a contributing aetiological factor.ConclusionVelopharyngeal insufficiency is a rare but significant complication of adenoidectomy. The majority of patients who developed velopharyngeal insufficiency following adenoidectomy did not have an identifiable predisposing factor. This has important implications for the consent process and when planning adenoidectomy.

The purpose of this study was to analyze the prevalence, diagnosis, and management of velopharyngeal insufficiency (VPI) in patients with craniofacial microsomia (CFM).Craniofacial microsomia patients 13 years of age and above treated at 2 centers from 1997 to 2019 were reviewed retrospectively for demographics, prevalence of VPI, and management of VPI. Patients with isolated microtia were excluded. Comparisons were made between patients with and without VPI using chi-square and independent samples t tests.Among 68 patients with CFM (63.2% male, mean 20.7 years of age), VPI was diagnosed in 19 patients (27.9%) at an average age of 7.2 years old. Among the total cohort, 61 patients had isolated CFM, of which 12 (19.6%) were diagnosed with VPI. Of the patients with isolated CFM and VPI, 8 patients (66.7%) were recommended for nasoendoscopy, of which only 2 patients completed. Seven isolated CFM patients (58.3%) underwent speech therapy, whereas none received VPI surgery. In contrast, 7 patients were diagnosed with both CFM and cleft lip and/or palate (CL/P), all of whom had VPI and were recommended for nasoendoscopy, with 5 (71.4%) completing nasoendoscopy, 6 (85.7%) undergoing speech therapy, and 6 (85.7%) undergoing corrective VPI surgery. Overall, we demonstrated that VPI was present in 27.9% of all CFM patients. On subset analysis, VPI was diagnosed in 20% of patients with isolated CFM and 100% of patients with CFM and CL/P. In addition, despite clinical diagnosis of VPI, a sizeable proportion of isolated CFM patients did not undergo therapy or surgical interventions.

BACKGROUND The pharyngeal flap is one of the most common secondary surgeries for the correction of velopharyngeal insufficiency (VPI) for patients with cleft palate and/or cleft lip and palate. This study aimed to demonstrate the effectiveness of the precision pharyngeal flap surgery performed by the senior author. MATERIALS AND METHODS Children with VPI, who underwent precision pharyngeal flap, were retrospectively examined. All surgical procedures were performed by the senior author. The flap size was individually configured based on the patients' preoperative nasopharyngoscopic analysis and speech function evaluation. Pre- and post-operative velopharyngeal functions were assessed using perceptual speech evaluation and nasometric analysis; factors affecting surgical outcomes were determined. RESULTS Of 138 patients, 112 (women: 53, men: 59) were included in analyses, according to the inclusion and exclusion criteria. The median follow-up period was 21 months (range: 9-120). Postoperative perceptual speech evaluation revealed improved velopharyngeal function in 108 (96.4%). There were no reports of postoperative hyponasality (preoperative, 1.8% versus postoperative, 0%; P = 0.053). Other parameters of perceptual speech evaluation (hypernasality, nasal emission, articulation error, and intelligibility) showed significant improvement postoperatively (P

Objective: Velopharyngeal insufficiency (VPI) remains a known complication of primary palatoplasty. We sought to identify factors associated with the incidence of VPI and create a predictive model for VPI development in our population. Design: A single-institution, retrospective review. Setting: Multidisciplinary clinic in a tertiary academic institution. Patients: A total of 453 consecutive patients undergoing primary palatoplasty from 1999 to 2016 were reviewed. Inclusion required follow-up past age 5. Patients who were non-verbal, and thus unable to undergo speech evaluation, were excluded. Main Outcome Measures: Primary outcome was VPI, defined as revision palatoplasty or recommendation by speech-language pathology. Results: Of 318 patients included, 179 (56%) were male. Median age at primary repair was 1.0 years (0.9-1.1) with a median age of 8.8 years at last follow-up. One hundred nineteen (37%) patients developed VPI at a median age of 5.0 years (3.8-6.5). Higher rates were seen with posterior fistula (65% vs 14%, P Conclusions: Length of follow-up, posterior fistulae, and genetic diagnoses are associated with VPI formation. Furlow repair may protect against formation of VPI. Use of allograft, Veau class, birth type, birth weight, and race are not independently associated with VPI formation.

BACKGROUND The purpose of this study was to evaluate the comparative incidence of obstructive sleep apnea following velopharyngeal insufficiency surgery in the United States. METHODS A retrospective analysis of cleft and noncleft pediatric patients who underwent velopharyngeal insufficiency surgery was performed using the IBM MarketScan Commercial Database. Patients were tracked longitudinally from 2007 to 2016 to evaluate the incidence of obstructive sleep apnea. Multivariable regression was used to evaluate predictors of postoperative obstructive sleep apnea and surgical revision. RESULTS A total of 1098 patients underwent a pharyngeal flap (61.0 percent), sphincter pharyngoplasty (22.2 percent), or palatal lengthening with or without island flaps (16.8 percent). Diagnoses were predominantly cleft lip and/or palate (52.8 percent) and congenital oropharyngeal anomalies (42.6 percent). Eighty patients (7.3 percent) developed obstructive sleep apnea at an average of 10.2 months postoperatively. Predictors of obstructive sleep apnea included older age (p = 0.014) and head and neck neoplasm (p = 0.011). The obstructive sleep apnea rate following sphincter pharyngoplasty was 11.1 percent, compared to 7.2 percent after pharyngeal flap surgery. Compared to sphincter pharyngoplasty, pharyngeal flap surgery was associated with a lower risk of further surgery (OR, 0.43; p = 0.010). Of patients with cleft lip and/or palate, 35 developed obstructive sleep apnea (6.0 percent) without a significant association with procedure type. CONCLUSIONS In this national claims database analysis of cleft and noncleft pediatric patients, the rate of obstructive sleep apnea following velopharyngeal insufficiency surgery was not significantly different for pharyngeal flap compared to sphincter pharyngoplasty.

INTRODUCTION The aim of this study was to evaluate pre-operative nutritional status, associated syndromes and abnormalities, and post-operative outcomes of patients with Pierre Robin Sequence (PRS) versus those with non-syndromic isolated cleft palate (CIP). METHODS Between January 1995 and December 2013, patients with a cleft palate Veau I-II according to the Veau classification with and without PRS who underwent primary repair were retrospectively analyzed. The nutrition status, age at the time of palatoplasty, additional anomalies, gestational complications, and post-operative speech abnormalities and outcomes were evaluated. RESULTS A total of 59 patients with PRS (PRS group) and 132 patients without PRS (non-PRS group) were included in the study. Of all patients, 92 were males and 99 were females with a mean age of 14 ± 4.18 (range, 6 to 26) years. The rate of gestational complications, enteral nutrition, complete cleft, additional anomalies, and velopharyngeal insufficiency was significantly higher in the PRS group (P

The presence of hypernasality in repaired cleft palate (CP) speech is a consequence of velopharyngeal insufficiency. The coupling of the nasal tract with the oral tract adds nasal formant and antiformant pairs in the hypernasal speech spectrum. This addition deviates the spectral and linear prediction (LP) residual characteristics of hypernasal speech compared to normal speech. In this work, the vocal tract constriction feature, peak to side-lobe ratio feature, and spectral moment features augmented by low-order cepstral coefficients are used to capture the spectral and residual deviations for hypernasality detection. The first feature captures the lower-frequencies prominence in speech due to the presence of nasal formants, the second feature captures the undesirable signal components in the residual signal due to the nasal antiformants, and the third feature captures the information about formants and antiformants in the spectrum along with the spectral envelope. The combination of three features gives normal versus hypernasal speech detection accuracies of 87.76%, 91.13%, and 93.70% for /a/, /i/, and /u/ vowels, respectively, and hypernasality severity detection accuracies of 80.13% and 81.25% for /i/ and /u/ vowels, respectively. The speech data are collected from 30 control normal and 30 repaired CP children between the ages of 7 and 12.

Background To assess speech results following the treatment of mild to moderate velopharyngeal insufficiency (VPI) post cleft palate surgery with autologous fat grafting to the velopharynx. Methods A retrospective study was conducted on 9 consecutive patients who underwent velopharyngeal fat grafting for the treatment of VPI at the Red Cross War Memorial Children's hospital from 2010 to 2014. All the patients previously had primary palatoplasty performed and subsequently developed VPI. Patients were assessed pre- and postoperatively by an experienced speech and language therapist looking at perceptual speech and by 2 senior cleft surgeons interpreting lateral view videofluoroscopies. Results Eleven fat grafting procedures were performed on 9 patients and an average of 5.64 mL (range 1-7 mL) of autologous fat was transferred to the velopharynx. The average age at the time of operation was 6.5 years (range 3-14 years) with a follow-up period of 18 months (range 7-34 months). Most of the patients (7 out of 9) showed improved speech after fat grafting. One of the 7 patients had multiple procedures. The 2 who did not show speech improvement only had a single procedure. There were no complications related to the fat grafting procedure. Conclusion This small study suggests that fat grafting either as a single procedure or as multiple procedures is an effective, safe, minimally invasive surgical alternative, and/or adjunct for the treatment of mild to moderate VPI in patients following cleft palate surgery and to the knowledge, is the first reported study from Africa.

Objective: Velopharyngeal (VP) closure has high impact on the quality of life, especially in patients with cleft palate. For better understanding the VP closure, it is important to understand the airflow dynamics of different closure patterns, including circular, coronal, sagittal, and circular with a Passavant’s ridge. The purpose of this study was to demonstrate the airflow characteristics of different velopharyngeal closure patterns. Methods: Sixteen adults with no notable upper airway abnormality who needed multislice spiral computed tomography scans as part of their clinical care. Airways were reconstructed. A cylinder and a cuboid were used to replace the VP port in three models of VP port patterns. Flow simulations were carried using computational fluid dynamics. Airflow pressures in the VP orifice, oral cavity and nasal cavity, as well as airflow velocity through the velopharyngeal orifice, were calculated. Results: The airflow dynamics at the velopharynx were different among different velopharyngeal patterns as the area of the velopharyngeal port increased from 0 to 25 mm2. The orifice areas of different closure conditions in four velopharyngeal closure patterns were significantly different. The maximal orifice area for adequate velopharyngeal closure was 7.57 mm2 in the coronal pattern and 6.21 mm2 in the sagittal pattern. Conclusions: Airflow dynamics of the velopharynx were correlated to the velopharyngeal closure patterns. Different closure patterns had different largest permitted orifice areas for getting the appropriate oral pressures for normal speech.

Pharyngeal flap surgery used for treatment of velopharyngeal insufficiency (VPI) may be followed by obstructive sleep apnea (OSA) especially if the patient has developed adenoid hypertrophy. However, adenoidectomy may adversely affect speech in these patients. The aim of this study was to assess the effectiveness of transnasal endoscopic power-assisted adenoidectomy in relieving OSA in patients with adenoid hypertrophy who underwent pharyngeal flap surgery, and the impact of the procedure on their speech. Transnasal endoscopic power-assisted adenoidectomy for nine children presenting with adenoid hypertrophy was performed. The patients had previously undergone pharyngeal flap surgery for treatment of VPI. Flexible nasopharyngoscopy was used in the diagnosis of adenoid hypertrophy. Pre- and postoperative polysomnography with measurement of apnea–hypopnea index (AHI) was done. Additionally, auditory perceptual assessment of speech (APA) and nasalance scores was measured pre- and postoperatively. All patients were shown to have OSA by polysomnography, and a larger adenoid size was significantly associated with a higher AHI. We achieved a significant improvement in AHI after adenoidectomy. However, six patients still demonstrated OSA, albeit with a reduced severity. Speech was not adversely affected postoperatively as the APA and nasalance scores showed non-significant changes. Adenoid hypertrophy may be encountered in children who undergo pharyngeal flap surgery, which may cause OSA. Transnasal endoscopic power-assisted adenoidectomy is a safe and effective method for treatment of OSA in those patients without prejudicing the pharyngeal flap, and it has no adverse effect on speech.

Auditory-perceptual judgements are regarded as the standard method for assessing speech disorders. However, the results of auditory-perceptual evaluations and rater reliability can be affected by various factors, such as concurrent problems in multiple speech subsystems. This study investigated the effect of a co-occurring articulation disorder on auditory-perceptual judgements of hypernasality and the effect of co-occurring hypernasality on judgements of an articulation disorder. The speech stimuli were sentences produced by a male speaker who simulated four levels of hypernasality (typical nasality, and mild, moderate, and severe hypernasality) at four levels of disordered articulation (typical articulation, and mild, moderate, and severe articulation disorder). Thirty speech and language therapy students used visual analogue scales to rate the severity of hypernasality and articulation disorder for each speech sample. Results showed that the hypernasality ratings were significantly higher when articulation disorder co-occurred compared to those without. However, there was no significant difference between mild, moderate and severe concurrent articulation disorder on hypernasality ratings. The speech samples with typical articulation and those with severe articulation disorder were rated as more severe in terms of articulation problem when combined with severe hypernasality. However, there was no significant hypernasality effect on articulation ratings for speech with mild or moderate articulation disorder. The present results generally agreed with previous findings regarding the effect of co-occurring speech problems on auditory-perceptual judgements. Clinicians are advised to be cautious of the potential impact. If possible, speech evaluation using instrumental techniques should be used to supplement auditory-perceptual judgements.

Introduction:Transpalatal advancement (TPA) is a procedure that is used when modern variants of uvulopharyn-gopalatoplasty are unable to provide enough anterior traction. Although successful in reduction of obstructive sleep apnea (OSA) parameters, it also comes with procedure-specific risks. Formation of an oro-nasal fistula (ONF) is a complication that results in significant morbidity and a protracted treatment course.Methods:After approval from the University of Wollongong Health Research Ethics Committee, a retrospective chart review of all cases undergoing TPA performed by a single surgeon over a 10-year period from 2008 to 2018 was performed. Patients underwent pre- and postoperative level 1 or 2 polysomnography. Factors potentially contributing to palatal complications, as well as pre- and postoperative polysomnographic parameters, subjective sleep questionnaires, and body mass index (BMI) were statistically analyzed where a P value Results:A total of 59 patients were included. Overall palatal complication rate was 25.4% (15/59), with the most common being transient velo-palatal insufficiency (VPI) (8/59, 13.6%). ONF developed in 4/59 (6.8%) of patients. None of the analyzed contributing factors for palatal complications were statistically significant, except the presence of a high-arched palate and development of ONF. All analyzed sleep parameters, as well as BMI, were significantly different when comparing pre- to postoperative results.Conclusion:This study suggests that TPA has a role in current sleep surgery paradigms and can significantly improve both objective and subjective outcome measures of OSA. Surgeons contemplating TPA on patients with high-arched hard palates should do so with caution.

Background Nasopharyngoscopy is a common method to evaluate velopharyngeal closure in patients with cleft palate. However, insertion of a fiberoptic nasopharyngoscope causes discomfort in patients. The aim of this study was to estimate the reliability of short-time exposure images obtained using 320-row area detector computed tomography (320-ADCT) as a novel evaluation method for the assessment of velopharyngeal function. Methods We evaluated five healthy adult volunteers and five postoperative adult patients with cleft palate. During a 3.3-s imaging exposure, the participants were asked to perform two tasks: nasal inspiration and subsequent oral expiration through a catheter into a water-filled cup. The movement of the velopharyngeal structures was recorded during each examination, and the presence of velopharyngeal insufficiency (VPI) and velopharyngeal closure (VPC) patterns were estimated. If VPI was detected, the cross-sectional area was also calculated. Cohen’s kappa and weighted kappa coefficients were used to evaluate the concordance of nasopharyngoscopy and 320-ADCT evaluation. Results Speech pathology evaluation did not reveal hypernasality in any study participant. Micro-VPI was detected by nasopharyngoscopy in one healthy volunteer and two patients. 320-ADCT detected micro-VPI in two more patients. The cross-sectional area of the VPI in these subjects ranged from 2.53 to 16.28 mm2. Nasopharyngoscopy and 320-ADCT were concordant in detecting VPI in eight participants (κ = 0.6) and in assessing VPC patterns in nine (κ = 0.82). Moreover, images obtained using 320-ADCT allowed for reduced dead angle and, thus, easy detection of micro-VPI and Passavant’s ridges. Conclusion Although the radiation exposure cannot be ignored, our novel evaluation method using 320-ADCT enables more detailed evaluation of VPC than nasopharyngoscopy. Future studies should investigate the relationship between 320-ADCT findings and speech pathology evaluations.

The pharyngeal flap is one of the oldest and most popular techniques for correction of velopharyngeal insufficiency. The authors describe a large series using a technique that combines a pharyngeal flap with a palate pushback to avoid common causes of operative failure while restoring the velopharyngeal mechanism.A retrospective cohort study was performed of patients who underwent a pushback pharyngeal flap by a single surgeon from 2000 to 2017. All patients had a preoperative nasoendoscopy diagnostic of velopharyngeal insufficiency. Operative technique involved elevation of the hard palate mucosa through a retroalveolar incision, passage of the flap through the nasopharyngeal mucosa opening, and inset with sutures through the hard palate mucosa.There were 40 patients with a median age of 9.7 years. Preoperative closure patterns were predominately coronal (85.7 percent), with poor posterior wall motion and an average gap size of 27.5 mm. Postoperative complications included flap dehiscence (n = 1), transient dysphagia (n = 2), obstructive sleep apnea (n = 4), and a palatal fistula and/or persistent velopharyngeal insufficiency that required further surgery (n = 6). At an average of 2.5 years postoperatively, 91.7 percent of patients achieved adequate velopharyngeal function, with significant improvements in the majority of speech metrics (p0.001).The pushback pharyngeal flap is a safe and effective technique for treatment of velopharyngeal insufficiency. Advantages include high, secure inset with prevention of palatal scar contracture and shortening.Therapeutic, IV.

The aim of the present study is to test the feasibility of modified Z-plasty palatoplasty for cleft palate repair in surgeries and provide a new surgical method. Forty cleft palate patients were selected as participants and divided into 2 groups in random. Twenty patients in the experiment group were treated by modified Z-plasty palatoplasty while the other 20 patients in the control group by double opposing Z-plasty and Sommerlad palatoplasty. By evaluating and observing postoperative velopharyngeal movement, speech intelligibility, nasal leaking, analysis of CSL (Computer Structure Language) and X-ray velopharyngeal lateral radiographs, Modified Z-plasty palatoplasty achieved better results than traditional operation. Satisfactory linguistic effects on incomplete cleft palate can be observed after modified Z-plasty palatoplasty treatment. So this method may be used as a clinical choice.

The surgical approach for the correction of residual velopharyngeal insufficiency requiring secondary surgery at Chang Gung Memorial Hospital is the modified Furlow palatoplasty with pharyngeal flap (mFP-PF). The aim of this study was to describe the mFP-PF technique and to determine the results obtained with regard to improvements in velopharyngeal function in patients undergoing this surgery. This retrospective analysis included 58 non-syndromic patients treated during the period 1992-2015 who complained of hypernasal speech after primary cleft palate repair and failed postoperative speech therapy. All of them underwent mFP-PF surgery. Preoperative and postoperative perceptual speech assessment results were obtained. The male to female ratio in the study group was 1.2:1, and the mean patient age at the time of surgery was 8.27 years. The patients underwent nasoendoscopic examination and the velar closing ratio was categorized as 0.1-0.4 in 53.4% and 0.5-0.7 in 46.6%. The assessment of speech after mFP-PF showed statistically significant changes for all perceptual speech outcomes. The incidence of repeat surgery was 3.4%. This study revealed that 96.6% of patients did not require second surgery for velopharyngeal insufficiency. Further studies on obstructive sleep apnoea in post-mFP-PF patients and improvements to the surgical technique should be considered.

Background: Submucous cleft palate (SMCP) has a heterogeneous presentation and is often identified late or misdiagnosed. Diagnosis is prompted by speech, resonance or feeding symptoms associated with velopharyngeal insufficiency. However, the broader impacts of SMCP on communication have rarely been examined and therefore are poorly understood. Aim: To describe the communicative profile of individuals with non-syndromic SMCP by examining speech, language and pragmatics (social language). Methods & Procedures: Fifteen participants with SMCP aged 5;1–12;8, without a genetic diagnosis, participated in the study. Participants completed standardized assessments examining language, resonance, speech and non-verbal intellect. Parents also completed the Children's Communication Checklist (CCC-2), which provided a measure of overall communicative ability, including pragmatic skills. Formal language outcomes were compared with two cohorts: 36 individuals with overt non-syndromic clefts and 129 individuals with no history of clefting. Outcomes & Results: Speech intelligibility was reduced secondary to hypernasality, disordered articulation and/or impaired phonology (n = 7) in children with SMCP. Poorer overall language outcomes were observed for children with SMCP compared with both those with overt clefts and no history of clefting (p < 0.001). Language scores for children with SMCP ranged from impaired (n = 6) to above the standardized mean (n = 4). Receptive and expressive language performance were independently correlated with non-verbal IQ (p < 0.01). Those with severe language impairment (n = 4) also had borderline or impaired non-verbal IQ. Parents reported that speech and semantics were the most affected sub-domains of communication, while scores were the highest for the initiation domain. Speech and language skills were correlated strongly with pragmatics (r = 0.877, p < 0.01). Conclusions & Implications: Overall, performance was variable within the SMCP group across speech, language and pragmatic assessments. In addition to well-documented speech difficulties, children with SMCP may have language or pragmatic impairments, suggesting that further neurodevelopmental influences may be at play. As such, for individuals with SMCP, additional clinical screening of language and pragmatic abilities may be required to ensure accurate diagnosis and guide both cleft and non-cleft related therapy programmes.

Background Velopharyngeal insufficiency (VPI) occurs when the velopharyngeal sphincter (VPS) is unable to completely seal anatomical closure between the nasal and oral cavities during speech. Palatal repair can restore VPS function but the prevalence of VPI after repair has been reported ranging from 20% to 40%. The combination of flexible videonasopharyngoscopy (FVNP) and multiplanar videofluoroscopy (MPVF) has been reported as the best approach for assessing the VPS mechanism and planning effective surgical procedures aimed to correct VPI. Objective To study the outcome of three different techniques for performing pharyngeal flaps with the common denominator of individually designing the flap according to findings of VFNP and MPVF. Material and methods A total of 140 cases of pharyngeal flap surgery were reviewed. Three surgeons performed 3 different surgical techniques. All cases underwent nasometry, VNP and MPVF preoperatively. All surgical procedures were carefully planned and designed according to findings of VNP and MPVF. Results Nasal emission was completely eliminated in all cases. One-hundred-thirty-four patients (95%) demonstrated mean nasalance within normal limits after the surgical procedure whereas 6 patients persisted with mean nasalance scores above reference values postoperatively. There were no intraoperative or postoperative complications in any of the cases. No clinical data of sleep disordered breathing was detected in any of the cases after 2 months of postoperative follow-up. However, one case presented with clinical data of sleep disordered breathing 8 months postoperatively. Conclusions The results of this study suggest that as long as pharyngeal flaps are being designed according to the findings of imaging procedures, different surgical techniques can provide similar successful outcomes with minimal complications.

Objectives: Competent velopharyngeal (VP) function is the basis for normal speech. Understanding how VP structure influences the airflow during speech details is essential to the surgical improvement of pharyngoplasty. In this study, we aimed to illuminate the airflow features corresponding to various VP closure states using computed dynamic simulations. Methods: Three-dimensional models of the upper airways were established based on computed tomography of 8 volunteers. The velopharyngeal port was simulated by a cylinder. Computational fluid dynamics simulations were applied to illustrate the correlation between the VP port size and the airflow parameters, including the flow velocity, pressure in the velopharyngeal port, as well as the pressure in oral and nasal cavity. Results: The airflow dynamics at the velopharynx were maintained in the same velopharyngeal pattern as the area of the velopharyngeal port increased from 0 to 25 mm2. A total of 5 airflow patterns with distinct features were captured, corresponding to adequate closure, adequate/borderline closure (Class I and II), borderline/inadequate closure, and inadequate closure. The maximal orifice area that could be tolerated for adequate VP closure was determined to be 2.01 mm2. Conclusion: Different VP functions are of characteristic airflow dynamic features. Computational fluid dynamic simulation is of application potential in individualized VP surgery planning.

This study aimed to compare outcomes of concomitant palatoplasty and sphincter pharyngoplasty with pharyngeal flap and sphincter pharyngoplasty alone for the treatment of velopharyngeal insufficiency in patients with 22q11.2 deletion syndrome. Thirty-one cases were identified for inclusion in the study. Patients were separated into 3 surgical groups: combined palatoplasty and sphincter pharyngoplasty (n = 11), pharyngeal flap (n = 7), and sphincter pharyngoplasty (n = 13). Outcome measures included perceptual speech analyses, surgical complications, and revision rates. There were no differences in preoperative speech analysis scores (P = .31). The combined palatoplasty and sphincter pharyngoplasty procedure had similar speech outcomes compared to pharyngeal flap, and both were significantly better than sphincter pharyngoplasty alone. Complication rates (P = .61) and the need for revision surgery (P = .25) were similar among all 3 groups. Concomitant palatoplasty and sphincter pharyngoplasty may be an alternative treatment for velopharyngeal insufficiency in children with 22q11.2 deletion syndrome.

Objective Tonsillar hypertrophy may affect velopharyngeal closure and speech resonance. The aim of this study was to assess the impact of hypertrophied tonsils on velopharyngeal function in children with normal palate and to measure the effect of tonsillectomy on velopharyngeal closure and speech resonance. Methods Eighty seven children with hypertrophied tonsils and normal palate were subjected to tonsillectomy for indications other than speech problems. Preoperative and postoperative evaluation of velopharyngeal function was performed. Auditory perceptual assessment of speech (APA) and nasometric assessment of nasalance was measured, and velopharyngeal closure was evaluated by flexible nasopharyngoscopy. Results Thirteen patients were excluded from the study because of associated adenoid hypertrophy. The mean baseline of APA scores showed insignificant changes postoperatively. However, significant postoperative changes of nasometric parameters were detected, and the overall postoperative nasalance score was improved for nasal and oral sentences. Also, improvement of velopharyngeal closure was observed postoperatively with accession of palatal mobility and significant increase in coronal closure pattern. Conclusion hypertrophied tonsils may impair velopharyngeal function in children with normal palate by hindering palatal elevation. Tonsillectomy is a beneficial procedure for such patients as it can improve the velopharyngeal closure and speech resonance.

Objectives Recently, the Velopharyngeal Insufficiency (VPI) Effects on Life Outcomes (VELO) questionnaire, which evaluates the impact of speech and swallowing difficulties on health-related quality of life (HRQoL) in patients with VPI (Skirko et al., 2012), was translated to Dutch (Bruneel et al., 2017). The purpose of this study was to evaluate the reproducibility, responsiveness and construct validity of this Dutch version of the questionnaire. Methods To evaluate the reproducibility, 50 parents and 14 children with cleft palate re-completed the questionnaire after two weeks. Thirty-five parents and 8 children with cleft palate completed the VELO questionnaire after one year for the evaluation of the responsiveness. The correlation between age and the VELO questionnaire (construct validity), and the internal consistency (Cronbach's α) were re-determined based on the responses of 73 parents and 24 children. Results Based on descriptive statistics, results of the Wilcoxon signed rank-test, and the absolute (SEM) and relative (ICC) consistency, the questionnaire showed good reproducibility. VELO scores did not significantly differ after one year, neither when performing separate analyses for the intervention (speech therapy) and the non-intervention group. Correlations indicated higher HRQoL, as perceived by the parents, with increasing age. The reverse was the case for the youth report. Cronbach's α showed excellent internal consistency for both reports. Conclusions The VELO questionnaire showed good reproducibility and internal consistency. Moreover, results reconfirmed the age effect on VELO scores. To understand the implications of the results regarding the questionnaire's responsiveness, future research should focus on the identification of factors influencing the patient's evolution in HRQoL.

Objective: To examine the effect of age on voice onset time (VOT) and VOT variability in children with repaired cleft palate. Methods: Twenty-two children with repaired cleft palate were allocated into two age groups: younger children (YC: n = 13) and older children (OC: n = 9). VOT measurements from monosyllabic words (/pɑ/, /tɑ/, and /kɑ/) and intraspeaker VOT variability estimated by coefficients of variation (CoV) of two age groups were compared. Results: Age was found to have a statistically significant effect on VOT and VOT variability. Specifically, OC had significantly longer VOT (F(1,66) = 4.196, p < 0.05) and less VOT variability (F(1,66) = 6.007, p < 0.05) for English voiceless stops than YC. No statistically significant main effect for speech sample or age by speech sample interaction was observed. Conclusions: Our data supplement the existing literature by adding VOT and VOT variability information for older children/adolescents with repaired cleft palate. Findings from the study suggest VOT patterns acquired at younger age appear to be further exaggerated and stabilized during the adolescent period among children with repaired cleft palate. A future study is necessary to determine different sources of VOT variability in children with a history of cleft palate, which may have clinical therapeutic implications.

Purpose Speech sound disorders and velopharyngeal dysfunction are frequent features of 22q11.2 deletion syndrome (22q). We report the first estimate of the prevalence of motor speech disorders (MSDs) in youth with 22q. Method Seventeen children and adolescents with 22q completed an assessment protocol that included a conversational speech sample. Data reduction included phonetic transcription, perceptual speech ratings, prosody-voice coding, and acoustic analyses. Data analyses included 3 motor speech measures and a cross-classification analytic. Prevalence estimates of speech and MSDs in youth with 22q were compared with estimates in speakers with other complex neurodevelopmental disorders: Down syndrome, fragile X syndrome, and galactosemia. Results Results indicated that 58.8% of the participants with 22q met criteria for speech delay, and 82.4% of the participants met criteria for MSDs, including 29.4% with speech motor delay, 29.4% with childhood dysarthria, 11.8% with childhood apraxia of speech, and 11.8% with concurrent childhood dysarthria and childhood apraxia of speech. MSDs were not significantly associated with velopharyngeal dysfunction. Conclusions In summary, 82.4% of the participants with 22q met criteria for 1 of 4 MSDs, predominantly speech motor delay and childhood dysarthria. Cross-validation of the present findings would support viewing MSDs as a core phenotypic feature of 22q.

Background The treatment plan for cleft lip and palate varies among centers and requires long-term evaluation of its final outcome. Methods A consecutive series of patients born from 1994 to 1996 were reviewed. Inclusion criteria were complete unilateral cleft lip and palate, undergoing all treatment procedures performed by the team, and continuous follow-ups until 20 years of age. Exclusion criteria were incomplete data, having microform cleft lip on the contralateral side, presence of the Simonart band, and other abnormalities. Results A total of 72 patients were included. Average age at final evaluation was 21.3 years; 83.3 percent of patients underwent one-stage rotation-advancement lip repair and 16.7 percent underwent two-stage repair with an initial adhesion cheiloplasty. All patients underwent palate repair using the two-flap method at an average age of 12.3 months. Velopharyngeal insufficiency occurred and required surgical interventions in 19.4 percent during the preschool age and in 16.7 percent at the time of alveolar bone grafting; 56.9 percent of patients underwent secondary lip/nose revision during the growing age. Regular orthodontic treatment was administered to 34.7 percent of patients between 12 and 16 years of age. Orthodontic treatment and orthognathic surgery were applied in 37.5 percent of the patients after maturity. The average number of surgical procedures to complete the treatment was 4.8 per patient. Conclusions This treatment protocol provided generally acceptable final outcome after the 20-year follow-up. Some results were less ideal and have resulted in modifications of the planning and methods in the protocol. Clinical question/level of evidence Therapeutic, IV.

Introduction: Maxillary advancement may affect speech in cleft patients. The aim of this study was to evaluate whether preoperative velopharyngeal (VP) function and cleft type can predict VP function after a Le Fort I maxillary osteotomy. Materials and methods: One hundred consecutive nonsyndromic cleft patients (54 females, 64 males) who underwent Le Fort I osteotomies were retrospectively evaluated. Pre- and postoperative VP function was assessed perceptually and instrumentally by a Nasometer. A five-point scale was used to rate velopharyngeal insufficiency symptoms (VPI 0-4). To assess reliability, 30 video recordings were re-evaluated. Results: Preoperatively, 89% of patients had normal or insignificant VPI (0-1), and only 3% had moderate VPI (3). Postoperatively, 77% of patients had VPI values of 0-1 and 14% had moderate to severe VPI values (VPI 3-4). A positive correlation was found between pre- and postoperative VPI scores, whereas the cleft type did not affect speech results. Patients with a preoperatively normal VPI (0) were not at risk for postoperative velopharyngeal incompetence. Conclusions: There was an overall significant negative change in speech after a Le Fort I osteotomy. At-risk patients presented with borderline (1) or more severe VPI (2 and 3) preoperatively.

Objective: Some patients with cleft palate (CP) need secondary surgery to improve functionality. Although 4-dimensional assessment of velopharyngeal closure function (VPF) in patients with CP using computed tomography (CT) has been existed, the knowledge about quantitative evaluation and radiation exposure dose is limited. We performed a qualitative and quantitative assessment of VPF using CT and estimated the exposure doses. Design: Cross-sectional. Setting: Computed tomography images from 5 preoperative patients with submucous CP (SMCP) and 10 postoperative patients with a history of CP (8 boys and 7 girls, aged 4-7 years) were evaluated. Patients: Five patients had undergone primary surgery for SMCP; 10 received secondary surgery for hypernasality. Main Outcome Measures: The presence of velopharyngeal insufficiency (VPI), patterns of velopharyngeal closure (VPC), and cross-sectional area (CSA) of VPI was evaluated via CT findings. Organ-absorbed radiation doses were estimated in 5 of 15 patients. The differences between cleft type and VPI, VPC patterns, and CSA of VPI were evaluated. Results: All patients had VPI. The VPC patterns (SMCP/CP) were evaluated as coronal (1/4), sagittal (0/1), circular (1/2), and circular with Passavant’s ridge (2/2); 2 patients (1/1) were unevaluable because of poor VPF. The CSA of VPI was statistically larger in the SMCP group ( P = .0027). The organ-absorbed radiation doses were relatively lower than those previously reported. Conclusions: Four-dimensional CT can provide the detailed findings of VPF that are not possible with conventional CT, and the exposure dose was considered medically acceptable.

Speech has a very significant impact on the life quality of people with cleft and lip palate. Restore tissue anatomy and functionality is the main aim of primary palatal surgery. Multiple factors are associated with successful handling, including the need for a velopharyngeal insufficiency (VPI) secondary surgery. The study's aim is to determine speech and velopharyngeal function outcomes in children with cleft palate operated in our institution and to determine VPI secondary surgery outcomes, if appropriate. Clinical records of nonsyndromic patients with cleft palate born between January 2009 and December 2012, who performed their multidisciplinary care on our institution, were analyzed retrospectively. One hundred forty-two patients received primary palatal surgery. Eighty (56%) were male and 62 (44%) female. Twenty-two had soft cleft palate, 9 hard and soft cleft palate, 84 unilateral, and 27 bilateral cleft lip and palate. Twelve percent of patients presented palatal fistula, with a significantly higher presentation in Soft Cleft Palate and Hard and Soft Cleft Palate. Twenty-seven patients (19%) had surgical indication for VPI correction, and 20 of them received VPI surgery, before school age. Cleft type and gender were significantly associated with VPI surgery indication rate. Postsurgery, 80% presented normal resonance. Nasal emission improved in 85% of patients. Nasometry decreased from 45% to 31%. Hyponasality increased by 10%. One case presented total flap dehiscence. Preoperative planning must be done carefully and individualized to succeed. Future prospective research that considers all the variables for a correct analysis is advisable, to improve our results.
