Granulomatous and vasculitic diseases of the airway may be part of more widespread systemic disease but can occur in isolation. They may present to the ear, nose, and throat (ENT) surgeon initially with vague symptoms that mimic more common chronic inflammatory unified airway conditions, such as rhinitis, chronic rhinosinusitis, and asthma. Early diagnosis is associated with better long-term outcomes, so a high index of suspicion is required. Bloody nasal discharge and crusting are highly suspicious for granulomatous disease, which should also be considered in atypical or recalcitrant disease. A combination of clinical findings, serologic tests, imaging, and histology may be required to confirm the diagnosis..

Objective Although the absence of a runny nose and sore throat, both ear-nose-throat (ENT) symptoms, suggests community-acquired pneumonia (CAP), the association between ENT symptoms and coronavirus disease 2019 (COVID-19) pneumonia remains unclear. We therefore investigated the association between ENT symptoms and COVID-19 pneumonia. Methods We retrospectively recruited consecutive confirmed COVID-19 inpatients with and without pneumonia admitted to a single institution from April 1, 2020, to July 31, 2021. After a descriptive analysis, we implemented univariable and multivariable regression analyses to assess the association between ENT symptoms and COVID-19 pneumonia. Results The present study included 385 patients. Pneumonia patients exhibited lower rates of positive runny nose and sore throat than non-pneumonia patients. Univariable analyses found mean odds ratios of 0.59 and 0.61 and 95% confidence intervals (CIs) of 0.30-1.16 and 0.32-1.17 for runny nose and sore throat, respectively, and multivariable analyses found mean odds ratios of 0.73 and 0.70 and 95% CIs of 0.34-1.56 and 0.34-1.46, respectively. Conclusion Our study found no statistically significant association between ENT symptoms and COVID-19 pneumonia. Clinicians should be aware that, unlike CAP, there is no correlation between ENT symptoms and pneumonia among patients with COVID-19, so it is necessary to consider the possibility of pneumonia even in the presence of ENT symptoms.

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.

Obstructive sleep apnea is the most frequent sleep disorder worldwide, with rising incidence. Pharyngoplasty is an alternative treatment in patients not suitable to continuous positive airway pressure devices (CPAP). The aim of this study is to compare different surgical techniques of pharyngoplasty for treatment of obstructive sleep apnea and evaluate its influence in surgical success.Retrospective study of 92 patients that underwent pharyngoplasty for treatment of obstructive sleep apnea from 2001 to 2020. Included patients performed classic uvulopalatopharyngoplasty (UPPP), radiofrequency assisted uvulopalatopharyngoplasty (RF-UPPP) or barbed reposition pharyngoplasty (BRP). Surgical success was defined and outcomes and complications assessed for each procedure.Most patients were male, with a mean age of 49.36±9.6 years and a mean apnea hypopnea index (AHI) of 29.14±2.94events/h. Thirty-six patients performed classic UPPP, thirty-one underwent RF-UPPP and the remaining twenty-five performed BRP. BRP achieved the highest success rate (66%) in comparison with UPPP (57%) and RF-UPPP (54%) (p=0.032). Mean relative AHI reduction after surgery was not statistically different between three procedures (p=0.098), although there was a tendency for greater reduction with BRP. Most symptoms improved after surgery and snoring was the most recurrent symptom. BRP had less foreign body sensation after surgery, however, it was the procedure with highest rate of post-operative tonsillar bleeding.In our department, the introduction of recent techniques of velopharyngeal surgery, focused in functional and lateral muscular collapse, has translated into an increase in success rate after surgery. The relative ease of the procedure and reduction of long term complications make BRP an attractive alternative option for CPAP in OSA, in carefully selected patients.

Gonorrhoea infections are frequently diagnosed at extragenital locations in asymptomatic individuals and are historically related to poor recovery in culture, which hinders antimicrobial susceptibility testing. The aim of this study was to evaluate recovery rates of Neisseria gonorrhoeae by culture among asymptomatic individuals who tested positive by nucleic acid amplification tests between 2018 and 2019 in Barcelona (Spain). In total, 10 396 individuals were tested for N. gonorrhoeae on first-void urine, rectal, pharyngeal and/or vaginal swabs depending on sexual behaviour. Overall infection prevalence was 5·5% (95% confidence interval [CI] 5·0–5·9). Seven hundred and ten samples were positive corresponding to 567 individuals. The most common site of infection was the pharynx (71·3%), followed by rectum (23·1%) and genitals (4·7%) (P < 0·0001). The N. gonorrhoeae recovery rate in culture, time from positive screening to culture specimen and inoculation delay were calculated. Recovery rate was 21·7% in pharynx, 66·9% in rectum and 37·0% in genitals (25·0% vagina, 71·4% urethra) (P < 0·0001). Median culture collection time was 1 [0; 3] days, and median inoculation delay was 5·01 [4·99–7·99] h, with no impact on N. gonorrhoeae recovery, P = 0·8367 and P = 0·7670, respectively. Despite efforts towards optimizing pre-analytical conditions, the N. gonorrhoeae recovery rate in asymptomatic individuals is unacceptably low (especially for pharynx), representing a problem for monitoring antimicrobial-resistant infections.

The Glasgow Benefit Inventory (GBI) has been extensively used to report the benefit from otolaryngological surgery. Benefit from non-surgical management has not been reported, despite this being the outcome of most otolaryngology and audiology consultations.GBI responses from 4543 adults from the Scottish ENT Outcome Study were categorised by diagnosis. Benefit scores for different interventions within diagnostic categories for which surgery was not a potential management are reported using the revised 5-factor Glasgow Benefit Inventory (GBI-5F; 15 questions and 5 factors).Adult otolaryngology outpatient clinics in six university hospitals.Adults seen with conditions that had no surgical option and given non-surgical management.Overall, 80% of participants managed in Scottish Ear Nose and Throat Outcome Study (SENTOS) did not have surgery. A total of 1373 (30%) participants with various diagnoses were given reassurance and advice with no active intervention. There was no change in their GBI-5F total or factor scores, suggesting that they did not come to harm from their lack of active intervention. Hearing aids for bilateral sensorineural hearing loss gave greater benefit than reassurance in all factors, though individuals with a conductive impairment reported greater benefit in the Quality of life factor than those with a sensorineural impairment. Hearing aids and maskers produced benefit in the Support factor for patients with tinnitus. Epley's manoeuvre for benign paroxysmal positional vertigo gave benefit in the total score and the Quality of life factor compared with reassurance. Systemic medication for laryngo-pharyngeal reflux and topical medication for otitis externa gave no greater benefit in any factor or the total score compared with reassurance.The GBI-5F and its five factors give useful information for reporting the benefit of non-surgical interventions in adult otolaryngology and audiology clinics.

The aim of the study was to investigate changes in the naso-pharyngeal and oro-pharyngeal airway with varying degrees of mandibular flare.The investigators implemented a retrospective, observational study including CT data from patients fitting the inclusion criteria. Linear and angular measurements were used to assess the flare and transverse dimension of the mandible, while standard reference planes were used for assessment of airway dimensions. The primary outcome measures were to correlate and quantify the naso-pharyngeal and oro-pharyngeal volumes with mandibular flare. Secondary outcome measures were to study the intra-variable correlation. Significance level was fixed at 5% (α = 0.05).The sample included CT data from 30 individuals with apparently normal craniofacial skeleton (53% males and 46.7% female with a mean age of 29.53 years). Both nasopharyngeal and oropharyngeal volumes demonstrated moderate positive correlations with inter-condylar width (p = 0.020 and p = 0.038) and inter-condylar angles (p = 0.041 and p = 0.005) respectively. Linear regression modelling demonstrated that for every millimetre increase of the Inter-condylar width, the naso-pharyngeal and oro-pharyngeal airway volume increased by 0.423 cmsup3/sup(p = 0.020) and 0.381 cmsup3/sup(p = 0.038) respectively, and every degree increase of inter-condylar angle produced an increase the nasopharyngeal and oropharyngeal volumes by 0.376cmsup3/sup(p = 0.041) and 0.496cmsup3/sup(p = 0.005) respectively.Parameters of mandibular flare demonstrate statistically significant correlation to pharyngeal airway volume, which may be a relevant predictor to evaluate airway in patients undergoing corrective skeletal surgery.

Velopharyngeal insufficiency persists in 15 to 30% of children with cleft palate, despite early velar surgery. Pharyngoplasty using a superior pedicle flap is the most common secondary surgery to treat velopharyngeal insufficiency. This study aims to identify the criteria leading to indicate velopharyngoplasty in 3 groups of age.we conducted a retrospective single center study in the reference center for cleft palate in Paris from 2013 to 2016. We included 61 children with non-syndromic cleft operated on with a velopharyngoplasty for velopharyngeal insufficiency. Pre-operative speech and surgical assessments, as well as the operative reports of the children, were analyzed retrospectively using multivariate models.We included 61 patients. The only criteria factor for an early velopharyngoplasty was the Pittsburgh Weighted Speech Scale (PWSS) score (OR 1.20, CI 95% 1.07 to 1.4 ; P=.006). Criteria for a late velopharyngoplasty were a degradation of the velopharyngeal function (OR 16.07, CI 95% 1.7 to 518.7 ; P=.041) and lost of follow-up (OR 5.78, CI 95% 3.9 to 4320 ; P=.017).Criteria for early and late velopharyngoplasty were identified, and we demonstrated the insufficiency of Borel-Maisonny classification for scientific clinical study.

Surgeons have traditionally believed that swallowing is mainly dependent on gravity after total glossolaryngectomy. However, swallowing function after total glossolaryngectomy varies widely among patients, and a thorough analysis is lacking. The authors aimed to clarify the swallowing function after total glossolaryngectomy and determine whether it is primarily dependent on gravity. The authors retrospectively analyzed videofluorographic examinations of patients who underwent total glossolaryngectomy and free or pedicle flap reconstruction. The authors enrolled 20 patients (12 male; mean age, 61 years; age range, 43 to 89 years). All patients demonstrated constriction of the reconstructed pharynx to some degree, and no patient's ability to swallow was dependent on gravity alone. Videofluorography showed excellent barium clearance in eight patients and poor clearance in 12. All patients with excellent clearance showed strong constriction of the posterior pharyngeal wall, whereas only 8.3 percent of the patients with poor clearance showed adequate constriction, which was significantly different ( p = 0.0007). Velopharyngeal closure and lip closure also contributed significantly to excellent clearance ( p = 0.041). The shape of the reconstructed pharynx (depressed, flat, protuberant) showed no statistically significant association with excellent clearance. Contrary to previous understanding, constriction of the remnant posterior pharyngeal wall played an important role in swallowing after total glossolaryngectomy, and gravity played a secondary role. Dynamic posterior pharyngeal wall movement might result from the increased power of the pharyngeal constrictor muscle and compensate for the immobility of the transferred flap. A well-functioning pharyngeal constrictor muscle and complete velopharyngeal and lip closures can contribute to excellent barium clearance in patients after total glossolaryngectomy.Therapeutic, III.

Velopharyngeal dysfunction (VPD) occurs when there is inadequate closure of the velopharyngeal sphincter during speech. An incompetent velopharyngeal sphincter may require surgical intervention to create a functional seal between the oropharynx and the nasopharynx during speech. To date, no single pharyngoplasty procedure has emerged as superior to another, and the comparison of results between studies has been limited by variation in outcomes reporting. Here, we use the newly defined Core Outcome Set for VPD (COS-VPD) to report a consecutive series of 109 patients managed with a midline pharyngeal flap and simultaneous dissection and repositioning of the velar muscles. The overall 30-day postoperative complication rate was 3.6% (4 out of 109 patients). At 12-month follow-up, 79.3% of patients experienced a statistically significant improvement in hypernasality. Seven patients (6.4%) developed obstructive sleep apnoea (OSA) postoperatively, and this was confirmed with polysomnography, with four (3.6%) patients requiring takedown of the pharyngeal flap. Seven patients in total (7.3%) required takedown of the pharyngeal flap and sphincter pharyngoplasty because of insufficient improvement of their VPD following the initial procedure. Patient-reported outcomes were investigated using the Velopharyngeal Effects on Life Outcome (VELO) instrument, and a mean total score of 74.5 out of 100 was recorded. We conclude that cleft surgeons should not be dissuaded by historical concerns about high rates of perioperative complications and OSA and should consider including the pharyngeal flap in their armamentarium when managing patients with VPD.

The aim of this study was to compare the effectiveness of Harmonic Focus+ scissors with the conventional surgical method regarding surgical blood loss and transfusion of blood products in the surgical treatment of head and neck tumours. In a retrospective study, the intraoperative blood loss, number of units of transfusion products given, operating time, and inpatient length of stay of 74 patients with squamous cell carcinoma were compared. Patients who underwent classic tumour surgery were compared with a group treated with Harmonic Focus+ scissors. A significantly lower intraoperative blood loss (496.15 ml vs 1096.0 ml, respectively; P = 0.002) and shorter operation time (436.89 minutes vs 493.13 minutes, respectively; P = 0.030) were achieved using the Harmonic Focus+ scissors when compared to the classic tumour surgery. Additionally, fewer units of blood products needed to be transfused (administration of red cell concentrates, P

Clefts of the lip or palate (CLPs) are the most common craniofacial birth defect, with a worldwide incidence of ~1 in 700 live births. The objective of this study is to assess the characteristics of the nasopharyngeal airway in growing vs. non-growing cleft lip/palate subjects and compare them with normal subjects. This retrospective study analyzed eighty-seven scans of three groups from cone beam computed tomography (CBCT). The cone beam computed tomography (CBCT) scans were coded and landmarks were identified using a Dolphin three-dimensional (3D) imaging software server (version 11.7; Patterson Dental Supply, Chatsworth, Calif). All values showed strong measurement reliability (>80), except for the nasopharynx measurement. Regarding gender difference, for the nasopharynx, female subjects (1261.32 ± 713.94) showed the lowest significant values in non-growing unilateral compared to males (6496.8 ± 2987) at p = 0.008. For oropharynx, in the growing bilateral cleft group, male subjects (13,046.79 ± 5521.89) showed a significant difference (p = 0.046) compared to females (8468.98 ± 4279.99). MP-SN, B, A, SNA., SN.B., and ANS-ME showed significant differences for cephalometric parameters (p < 0.05). Despite significant differences in linear and angular measurements, volumetric airway measurements showed no significant differences in the growing groups. For non-growing cleft subjects, the cleft anomaly significantly affected the nasal cavity and left maxillary sinus volumes.

Objectives SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) structure and host tropism have changed over time, and so has the involvement of throat structures. This infodemiological analysis is hence aimed at investigating the evolution of throat symptoms during the COVID-19 pandemic in the US. Methods We searched Google Trends using the medical search terms “ageusia”, “hoarseness”, “dysphonia”, “pharyngitis” and “laryngitis”, setting geographical location to “United States”, within the past 5 years. The weekly Google Trends score for these symptoms, which reflects their national Web popularity, was divided in three parts, as “pre-COVID” (July 2017 to February 2020), COVID-19 “pre-Omicron” (March 2020 to November 2021), and COVID-19 “Omicron” (December 2021 to July 2022), and then compared. Results The volume of searches for ageusia increased in the pre-Omicron period and remained significantly higher also during Omicron prevalence, though a significant decrease (∼30%) occurred with Omicron lineages compared to previous strains. The Google searches for hoarseness and dysphonia were relatively similar between the pre-COVID and pre-Omicron periods, but then significantly increased during Omicron predominance. The Google searches for pharyngitis and laryngitis decreased in the pre-Omicron period, but then considerably increased following Omicron emergence. Omicron endemic spread could be significantly and independently predicted by the volume of searches for pharyngitis, laryngitis and hoarseness. Conclusions The epidemiological burden of throat symptoms has considerably changed after Omicron emergence, with a lower likelihood of developing chemosensory dysfunctions and enhanced risk of throat involvement.

Flexible endoscopic procedures (FEP) using a working channel allowed otolaryngologists to perform more procedures on the pharynx and the larynx under local anesthesia. The purpose of this work is to demonstrate the feasibility and safety of this technique by studying the adverse effects of this practice in an office-based setting.This is a monocentric retrospective cohort study. We searched the database using the French procedural code for FEP performed in an outpatient setting between January 2005 and December 2020. Data regarding the patient's characteristics, indications, and periprocedural complications were extracted.In total, we included 231 patients with a total of 308 FEP: 36% biopsy, 20% hyaluronic acid injection (including 3.5% at the level of the cavum), 20% injection of other substances (in descending order: botulinum toxin, cidofovir, physiological serum, cortisone), 20% exploration for an occult tumor, 3% samples for microbiological analysis, 1% other procedures. Of the 308 FEP included in this study, 24 patients (10.3%) had complications corresponding to 7.8% of the procedures performed. During the procedures, reported complications include minor laryngeal bleeding (n = 5), vasovagal syncope (n = 5), laryngospasm (n = 1) or nausea (n = 3), dysphagia (n = 3), and voice disorders (n = 3). Post-procedural complications were hypertensive crisis (n = 1), asthma attack (n = 1), pneumonia (n = 1), laryngitis (n = 1). Using the Clavien-Dindo classification system, these complications could be defined as grade I (laryngeal bleeding, vasovagal syncope, laryngospasm, dysphagia, nausea, voice disorders, and laryngitis) and grade II (hypertensive crisis, asthma attack, pneumonia) in 9.1% and 1.2% of cases, respectively. Most of these complications were self-limiting, while asthma attacks, pneumonia, laryngitis, and voice disorders required a medical intervention. All complications were managed without sequelae. There was no serious complication grade (no grade III, IV or V).FEP, which is now well standardized in our institution, makes it possible to carry out a wide range of interventions with little morbidity. These results are in line with those of literature but this technique remains out of nomenclature in France. Our experience led to the development of an evidence-based standard of care that can serve as a framework for practitioners on a nationwide level, while the work to establish official guidelines by the French society of phoniatrics and laryngology is in progress.

Patients with head and neck cancer may suffer from xerostomia after repetitive surgery or radiation therapy. Free colon tissue transfer was used to restore the lubrication of the oral cavity, and a bacteriological study in mice was conducted to evaluate how the intestine transfer from the intra-abdominal to extra-abdominal locations may affect bacterial colonization.Twelve patients received free colon transfer for the reconstruction of their intraoral mucosal defect following trismus release. Thirty-five patients received ileocolon flap transfer to fill the pharyngeal defects. In an animal study with mice, a pedicled ileum segment was transferred to the subcutaneous space of the abdominal wall. The transferred ileum segments were biopsied for bacterial genome analysis after 3 months.All but one transferred flap survived. Colon secretion was suitable for oral lubrication without the unpleasant smell 1 month postoperatively. In an animal study, genome analysis showed that the same bacterial species still existed in the transferred intestinal tissue.No unpleasant smell or infections were noted in this clinical series despite the animal study showing that the bacterial spectrum did not change in the transferred intestine. Therefore, free colon tissue transfer could safely provide lubrication in patients with xerostomia.

Feminization Laryngoplasty evolved from the aim to change a voice from a male quality to a female quality. Larynx and pharynx in a male have undergone enlargement during puberty and as there is no endocrine method for shrinking structures, a surgery that reduces the size of male structures toward the size of female structures might appropriately alter the voice. A smaller larynx and pharynx might raise both the fundamental frequency of the voice and the resonant frequency of the vocal tract. The surgery is used for transgender individuals who desire a female voice, for individuals who fail speech therapy and for complications of tracheal shave procedures whereby the vocal cords have been loosened.

Throat packs (TP) are used in upper airway surgery to avoid accumulation and aspiration of blood, foreign bodies, and fluids. But side effects such as sore throat and TP retention have been reported and challenge the standardized use of TP. The aim of this study is to compare benefits and side effects of TP versus no TP for upper airway procedures in intubation anesthesia.One hundred forty-eight patients with surgical interventions at the upper airway under intubation anesthesia were included. Of those, n = 74 each were treated without (A, control) and with (B) TP. Study group B was subdivided whether TP was placed by the surgeon (B1; n = 37) or by the anesthesiologist (B2; n = 37). TP-related side effects such as sore throat, foreign body sensation, hoarseness, dyspnea, difficulty of swallowing, nausea, retching, nausea, aspiration, and pneumonia as well as the influence of TP design and the applicant (surgeon or anesthetist) were analyzed.A significantly increased rate of difficulty of swallowing (p = 0.045), intensity of sore throat (p = 0.04), and foreign body sensation (p = 0.024) was found in group B when compared to group A. There was no correlation between hoarseness, dyspnea, nausea, retching, and TP. No case of aspiration or pneumonia was seen but one TP was accidentally forgotten in the patient. B2 showed an increased frequency of difficulty swallowing, followed by A and B1. B1 led to the highest incidence of nausea followed by the A and B2.The use of TP led to a high rate of side effects without showing the propagated advantages.The use of TP must be considered critically and cannot generally be recommended without specific reasons, such as high aspiration risk.

Purpose: This study compared the concordance between two validated videofluoroscopic pharyngeal residue outcome scales used in clinical and research settings: the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) and the Analysis of Swallowing Physiology: Events, Kinematics and Timing (ASPEKT) percent residue metric. Method: Two trained raters completed independent and blinded videofluoroscopic ratings of both DIGEST efficiency and ASPEKT percent pharyngeal residue outcomes for bolus trials of 5 cc Varibar thin liquid ( n = 223), thin liquid comfortable cup sips ( n = 223), and 5 cc Varibar thin honey ( n = 223). Spearman's rho and Kruskal–Wallis analyses were performed for each bolus type. Results: Significant associations between DIGEST and ASPEKT pharyngeal residue outcomes were noted for 5 cc thin ( r = .54, p < .001), cup sip thin ( r = .41, p < .001), and 5 cc thin honey ( r = .60, p < .001) bolus trials. ASPEKT percent residue increased across worsening DIGEST efficiency ordinal scale levels, with a main effect for each bolus type. Post hoc analysis revealed significant differences in the ASPEKT percent residue values between each DIGEST pairwise comparison for the thin cup sip bolus trial and for each pairwise comparison except between the moderate-to-severe (less than half vs. majority) ordinal levels for the 5 cc thin and 5 cc honey bolus trials, p < .05. Conclusions: Perceptual, ordinal (DIGEST) and quantitative, pixel-based (ASPEKT) videofluoroscopic pharyngeal residue outcomes were associated in this data set of 669 bolus trials. Future research is warranted to confirm these results.

Objective Several clinical practice guidelines have been produced and disseminated for the evaluation of a neck mass. However, to date, the quality and methodologic rigor of these clinical practice guidelines have not been appraised. Therefore, this study set out to identify and assess the methodologic quality of national and international guidelines for the evaluation and management of neck masses in adults. Methods We conducted a comprehensive search of EMBASE, MEDLINE/PubMed, SCOPUS and grey literature sources until September 2020. The quality of these guidelines was assessed by four reviewers using the Appraisal of Guidelines for Research and Evaluation, 2nd edition (AGREE II). Domain scores were considered acceptable quality if they scored >60%, and Intraclass Correlation Coefficients (ICC) were calculated to assess agreement among the appraisers. Results Seven guidelines were assessed for evaluation. Among these, only the American Academy of Otolaryngology (AAO), Cancer Care Manitoba (CCMB), and the American Society of Clinical Oncology (ASCO) achieved an overall rating of “high”. The remaining four guidelines achieved ratings of either “average” or “low”. The “Scope and Purpose” domain achieved the highest mean score (94.4% ± 5.0%), and lowest was “Applicability” (51.5% ± 29.2%). ICC analysis showed substantial to very good agreement across all domains (0.75–0.98). Conclusion These findings highlight the variability in methodologic quality of guidelines for the evaluation and management of adult neck mass. The results from this analysis highlight the need to improve guidelines development process for this topic and may guide the selection and use of these guidelines in clinical practice.

STUDY OBJECTIVES: This review aimed to evaluate the association between craniofacial features in children and adolescents with pediatric obstructive sleep apnea (OSA). METHODS: Seven databases were searched to fulfill our research objectives. Clinical studies that included participants younger than 18 years with fully diagnosed OSA or without OSA and that evaluated skeletal, soft craniofacial features, or dental arch morphology were considered for this review. The risk of bias and certainty of evidence were assessed. A meta-analysis was performed when low methodological and clinical heterogeneity were detected. This review followed the protocols recommended by the Preferred Reporting Items for a Systematic Review and Meta-analysis (PRISMA-2020) guidelines. RESULTS: Nine studies were identified at the end of the selection process, from which 5 did not report differences. Four studies reported differences between craniofacial features when OSA was compared to an asymptomatic control group. Mandibular retrognathia, reduced anteroposterior linear dimensions of the bony nasopharynx (decreased pharyngeal diameters at the levels of the adenoids), longer facial profile, and a narrower intercanine width were described among children with OSA. A meta-analysis was performed considering the studies with a similar methodological approach, and no differences were observed in all the considered cephalometric angles (SNA, SNB, ANB, NSBa, U1-L1, U1-SN). All the included studies were considered at low risk of bias even though some limitations were noted. CONCLUSIONS: Due to the very low to moderate level of certainty, neither an association nor a lack thereof between craniofacial morphology and pediatric OSA can be supported by these data.

This article summarizes the results of a retrospective population-based cohort study using the statistical database of SEER*Stat 8.3.54 (produced 3/5/2018 for diagnosis years 1973-2014) to assess, determine, compare, and summarize the occurrence, long-term survival, and mortality indices of 218,066 patients with oral cavity and pharynx cancers by age, sex, race, stage, grade, and disease duration.

The study aimed to evaluate the morphologic changes in the pharyngeal airway after bimaxillary surgery in skeletal Class III malocclusion patients with or without asymmetry. We also analyzed the correlation between positional changes in the menton, hyoid bone, and changes in the dimensions of the pharyngeal airway.We included 32 patients with skeletal Class III malocclusion who underwent bimaxillary surgery. There were 16 subjects in the symmetry group (10 male, 6 female; mean age, 22.44 ± 5.14 years), and 16 in the asymmetry group (10 male, 6 female; mean age, 21.38 ± 4.62 years). Preoperative and postoperative (2 months after surgery) cone-beam computed tomography scans were taken and then analyzed by comparing postoperative changes in each group.The anteroposterior lengths at the uvula level (P2L) and epiglottis level (P3L) were significantly decreased in the symmetry group. The P2L was also significantly decreased in the asymmetry group, and a difference in the P3L was observed. However, there was no significant change in the width at the uvula level (P2W) and epiglottis level (P3W) in the symmetry group. In contrast, in the asymmetry group, P2W and P3W were significantly decreased. The cross-sectional ratio was significantly decreased P2 (P2L/P2W) and P3 (P3L/P3W) in the symmetry group. However, a statistically significant decrease occurred only at P3 in the asymmetry group. Anteroposterior positional changes of the menton and P2L (r = -0.370; P .05), P3L (r = -0.414; P 0.05), and P3L/P3W (r = -0.361; P 0.05) were correlated.Differences in the morphologic features of the pharyngeal airway after bimaxillary surgery was observed in both the symmetry and asymmetry groups. Bimaxillary surgery with a mandibular setback in patients with skeletal Class III malocclusion worsened morbidity of the elliptical structure of the pharyngeal airway. However, it worsened less in the asymmetry group than in the symmetry group.

Cleft palate is a congenital malformation that causes hypernasality and decreases the intelligibility of pronunciation and leads to velopharyngeal insufficiency. It causes difficulty in language development. Many studies and treatments have been conducted to reduce this problem, but there are limitations. In this study, the effect obtained through continuous positive airway pressure (CPAP) treatment was analyzed by statistical methods.From May 2012 to December 2018, using patient demographics, computed tomography (CT) scan, and nasalance test was performed on 25 patient groups treated with CPAP devices for 8 weeks to confirm the effect after 6 months.After CPAP treatment in a total of 25 patients, 13 patients had a therapeutic effect. The average age of the patient group with treatment effect (effective group [EG]) was 51.2months, and the patient group with no treatment effect (ineffective group [iG]) was 73.6 months. ( P0.05). In CT data analysis, the highest palatal arch point was 6.31 mm in EG and 7.36 mm in IG, which was lower in EG ( P0.01), and the distance from incisive foramen to posterior pharyngeal wall was 41.39 mm in EG and 49.07 mm in IG ( P0.05).Through the statistical analysis, the group of patients who were effective in treatment had a low age at the beginning of treatment, the height of highest palatal arch point was low on CT data, and the length of distance from incisive foramen to posterior pharyngeal wall was short. It will be helpful to set the CPAP treatment patient group with respect to the results and age and CT data when treating VPI patients.

A 55-year-old woman was seen at an oral and maxillofacial surgery department because of a large oral swelling and complaints about difficulty eating, nasal speech and fatigue. She had full dentures in her upper jaw. Intraorally, a pain-free, pedunculated, combined solid-elastic and bone-hard tumour was found in the left maxillary tubercle region. A large, fibroepithelial polyp was diagnosed based on clinical and histopathological findings. Six weeks post-operatively, the complaints had disappeared. Chronic irritation of the oral mucosa can result in an oral fibroepithelial polyp that can be distinguished from peripheral ossifying fibroma or giant cell fibroma after histopathological examination. Such a polyp can grow to a large size if the source of irritation is not removed.Een 55-jarige vrouw werd gezien op een afdeling voor mka-chirurgie vanwege een forse orale zwelling en klachten van moeite met eten, een nasale spraak en oververmoeidheid. Zij had een volledige gebitsprothese in de bovenkaak. Intraoraal werd in regio van het tuber maxillare links een pijnvrije, gesteelde en gecombineerd vast-elastische en beenharde tumor gezien. De werkdiagnose fibro-epitheliale poliep werd histopathologisch bevestigd. Zes weken postoperatief waren de klachten verdwenen. Chronische irritatie van de orale mucosa kan resulteren in een orale fibro-epitheliale poliep die histopathologisch kan worden onderscheiden van een perifeer ossificerend fibroom en een reuscelfibroom. Wanneer de irritatiebron niet verwijderd wordt, kan de poliep tot grote omvang uitgroeien.

Dysphagia post head and neck cancer (HNC) multimodality treatment is attributed to reduced pharyngeal strength. We hypothesized that pharyngeal tongue base augmentation for dysphagia (PAD therapy) would increase pharyngeal pressures during swallowing thereby improving swallow symptoms.Adults with moderate-severe dysphagia post-HNC treatment had PAD therapy using a temporary filler (hyaluronic acid [HA]), with follow-up long-lasting lipofilling. Swallowing preprocedure and postprocedure was assessed with the Sydney Swallow Questionnaire (SSQ), High-Resolution Pharyngeal Manometry (HRPM), and Videofluoroscopic Swallowing Study (VFSS). Statistical comparison utilized paired tests.Six participants (all male; median age 64 years [IQR 56, 71]) underwent PAD therapy at a median of 47 [IQR 8, 95] months post-treatment. SSQ scores reduced from baseline (mean 1069 [95%CI 703, 1434]) to post-HA (mean 579 [76, 1081], p 0.05), and post-lipofilling (491 [95%CI 913, 789], p = 0.003, n = 4). Individual participants demonstrated reduced Swallow Risk Index, Bolus Presence Time, and increased Upper Esophageal Sphincter opening, but mesopharyngeal contractile pressures were unchanged. VFSS measures of aspiration, residue, and severity were unchanged.Novel PAD therapy is safe and improves dysphagia symptoms. Biomechanical swallowing changes are suggestive of more efficacious bolus propulsion with conservative filler volume, but this was unable to resolve residue or aspiration measures.

HPV is the most common sexually transmitted disease in the United States, the principal cause for cervical cancer, and the principal cause for the recent increase in head and neck squamous cell cancers. Current interventions and research goals fail to sufficiently address the need to prevent HPV, and continued stigmatization of HPV as a female disease further discourages young patients from seeking the vaccine.This paper will review the epidemiology of HPV, including the rise in male cases and cancers, the immunogenicity of the vaccine, results of efficacy and effectiveness trials, and the social and operational challenges to preventing HPV infection within the United States. Statistics were sourced from the CDC. Studies were found through PubMed searches related to HPV. Priority was given to articles published in the last ten years, and policy statements from major associations were considered.To improve vaccination rates, diversified physician engagement in vaccinating adolescents, better knowledge sharing about vaccine hesitancy, and specifically targeting males to bridge the gender gap are all necessary. Further, childhood HPV vaccinations and therapeutic vaccinations remain under-researched but potentially effective methods to diminish the incidence of HPV-associated cancers.

Objectives Expansion sphincter pharyngoplasty is a well-known palatal correction surgery applied for obstructive sleep apnea patients. Even though high success rates are reported, in some patients, the desired outcome cannot be achieved. Therefore, patient selection is crucial to avoid undesirable outcomes. In this study we present our results with expansion sphincter pharyngoplasty, and we aim to show the difference between supine and non-supine apnea in terms of their response to the surgery, in order to utilize position dependency for selection of surgical candidates. Methods Pre- and post-operative polysomnography results of patients who underwent expansion sphincter pharyngoplasty were analyzed retrospectively. Total AHI, supine AHI, non-supine AHI, supine/non-supine AHI ratio and surgical success values are compared. Results 85 patients were included to the study. Mean AHI significantly decreased from 48.7 ± 27.99 to 26.37 ± 21.16 with the surgery. Surgical success rate was found to be 51.8%. Both supine and non-supine apnea decreased significantly with the surgery, but the decrease was significantly higher in non-supine apnea (20.6% to 39.1% respectively, p = 0.016). There was significant negative correlation between pre-operative supine to non-supine AHI ratio and the change in AHI, showing that supine dominant patients had less improvement with the surgery (r = 0.274, p = 0.01). Conclusion Expansion sphincter pharyngoplasty is an effective surgery which achieves significant improvement in AHI. Non-supine respiratory events respond better to the surgery than supine events.

The pathogenesis of obstructive sleep apnea (OSA) is characterized not only by obstruction of the pharynx, but also by repeated obstruction. OSA onset is thought to involve four phenotypic traits: pharyngeal muscle responsiveness, respiratory center instability (loop gain), arousal threshold, and anatomical factors. Patients with lower muscle responsiveness are likely to have OSA, whereas those with higher responsiveness are not. When the loop gain is relatively high, reaction and suppression of the respiratory drive are repeated, decreasing ventilation and pharyngeal muscle activity and leading to mixed or central apnea events. Patients with a low arousal threshold tend to have frequent respiratory events and less severe respiratory efforts, whereas those with a high arousal threshold tend to have fewer respiratory events and more severe respiratory efforts. Pharyngeal muscle activity, as well as respiratory drive, increases during apnea and decreases after its release. Patients with a low arousal threshold have lower muscle responsiveness and instability of the respiratory center control, whereas those with a high arousal threshold have higher muscle responsiveness and relatively stable respiratory control. The overshoot and undershoot responses of the chemical drive and pharyngeal muscle tone characterize the periodic repetition of obstructive events, which are enhanced by the arousal response. The presence of certain anatomical factors is prerequisite for the onset of OSA. Also, not only volume and flow, but also stiffness and elasticity may contribute to the pathogenesis of OSA. Mouth breathing also plays an important role in the mechanism of pharyngeal collapse. These four factors influence each other, with the first three-muscle responsiveness, loop gain, and arousal threshold-in particular in a trinity. The era is already close in which not only anatomical treatment, but also treatments for other traits can be selected and combined according to the individual pathophysiological condition of each patient with OSA.

Objective The blowing time ratio, which is the ratio of the blowing time when the nostrils are open and closed, is significantly correlated with velopharyngeal pressure, not only during speech but also during swallowing. This study aimed to further evaluate the usefulness of the blowing time ratio as a screening tool to evaluate the swallowing pressure of patients treated for oral and oropharyngeal cancers using high-resolution manometery (HRM). Methods Ten patients treated for oral or oropharyngeal cancer were recruited for this study. Swallowing pressures at the velopharynx, oropharynx , and upper esophageal sphincter (UES) were measured using HRM. Their correlations with the blowing time ratio were analyzed. Results The blowing time ratio was significantly correlated with the swallowing pressures of the oropharynx (CC = 0.815, p = 0.004) and the velopharynx (CC = 0.657, p = 0.039), but not of the UES. Conclusions The present results further support our previous finding that the blowing time ratio is a useful screening tool to evaluate velopharyngeal and oropharyngeal swallowing pressures in patients treated for oral and oropharyngeal cancer.

This study reports our experience in a selected cohort of patients affected by mild-moderate OSAS, without tonsillar obstruction, and treated with pharyngoplasty.In a case-control retrospective study, we compared modified expansion sphincter pharyngoplasty (MESP) to modified barbed reposition pharyngoplasty (MBRP) in adult patients with oropharyngeal transversal collapse with a BMI ≤ 30 kg/mWe enrolled 20 patients: 10 treated with MESP and 10 treated with MBRP. Mean apnoea-hypoapnoea index (AHI) was 22.8 (± 5.63). We observed in both groups a significant reduction of AHI and oropharyngeal obstruction (p = 0.01), with a success rate, according with Sher's criteria, of 90% for MESP and 80% for MBRP, respectively. Post-surgical pain and snoring reduction were significantly lower with MBRP.We recorded similar success rates for both techniques. MBRP may be considered better than MESP due to less surgical time, no potential mucosal damage, absence of knots, and faster recovery with less pain.Gestione del collasso faringeo in pazienti affetti da sindrome delle apnee ostruttive di grado moderato.Riportare la nostra esperienza in una coorte selezionata di pazienti affetti da sindrome da apnee ostruttive del sonno (OSAS) lieve-moderata, senza ipertrofia tonsillare, trattati con faringoplastica.Confrontare in uno studio retrospettivo caso-controllo la Expansion Sphincter Pharyngoplasty modificata (MESP) e la Barbed Reposition Pharingoplasty modificata (MBRP) in pazienti adulti con collasso trasversale orofaringeo con BMI ≤ 30 e OSAS lieve-moderata. È stata effettuata una valutazione clinica, con raccolta di dati antropometrici e sleep endoscopy. Sei mesi dopo l’intervento sono stati rivalutati i sintomi e ripetuta la polisonnografia (PSG).20 pazienti, dieci trattati con MESP e dieci trattati con MBRP. Indice di apnea-ipopnea (AHI) medio di 22,8 (± 5,63). Abbiamo osservato in entrambi i gruppi una riduzione significativa dell’AHI e dell’ostruzione orofaringea (p = 0,01), con un tasso di successo secondo i criteri di Sher del 90% per MESP e 80% per MBRP. Il dolore post-operatorio e la riduzione del russamento erano significativamente più bassi nella MBRP.Abbiamo registrato percentuali di successo simili per entrambe le tecniche. L’MBRP può essere considerata superiore alla MESP per minor tempo chirurgico, assenza di potenziali danni alla mucosa, assenza di nodi e un recupero più rapido con meno dolore.

Obstructive sleep apnea (OSA) is a common respiratory disorder associated with the collapse of the upper airway during sleep. OSA may cause oxygen desaturation, arousals from sleep, and daytime sleepiness, in turn affecting quality of life. There is low success rate in existing OSA surgical treatments mainly due to heterogeneity of the OSA population and poor understanding of the mechanism of the upper airway collapse in each individual. However, advancements in computational simulation have led to some detailed structural modelling of the upper airway that may help to better understand its collapse mechanism in OSA. Alternative surgical treatment methods may be critically assessed with simulation prior to clinical adoption to provide personalized treatment insight for an OSA individual. This review summarizes the current literature related to the application of fluid structure interaction simulation for OSA analysis, with a focus on pharyngeal airway deformation mechanisms, airflow characteristics, and OSA surgical treatment efficacy; it also identifies the shortcomings of current models with suggestions for future studies. It is evident that the upper airway collapse mechanism, the anatomical factors affecting the location and timing of the collapse, and the association of the upper airway anatomical features with critical pressure (P

Pharyngeal collapse has been described as a decrease of more than 50% in the diameter of the lumen. However, there has been no study on changes in the pharyngeal lumen in clinically normal dogs. The hypothesis of this prospective, observational, and pilot study was that change in nasopharyngeal lumen would be over 50% in Beagle dogs without cardiopulmonary diseases. Thus, we assessed the nasopharyngeal luminal change using cervical radiography in Beagle dogs without respiratory signs or cardiac abnormalities. The study sample included 42 Beagle dogs without cardiopulmonary diseases. Cervical radiographies were acquired during inspiration and expiration, and nasopharyngeal luminal change (%) was calculated. The median nasopharyngeal luminal change was 16.6%, and nasopharyngeal luminal change over 50% was identified in two dogs. The nasopharyngeal luminal change was significantly associated with body condition score and body weight. There was no correlation between nasopharyngeal luminal change and age. This study revealed that change in nasopharyngeal lumen over 50% can be identified in Beagle dogs without cardiopulmonary diseases and may be over-diagnosed as partial pharyngeal collapse. Further studies for comparing change in nasopharyngeal lumen between clinically normal dogs and dogs with respiratory signs are warranted.

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.

Advanced hypopharyngeal tumours present complex clinical challenges, and where resection is attempted, there is a requirement for major reconstruction. Despite advances in surgical technique, outcomes remain poor for this patient group, and optimum treatment has yet to be established. We aimed to assess the treatment and outcomes of patients in our institution in the context of previous studies. All patients from 2008 to 2018 who underwent surgical management for hypopharyngeal tumours with pharyngo-laryngo-esophagectomy and flap-based reconstruction were included in the study. Demographic and outcome data were collected, and patient-reported outcomes were solicited from surviving patients using the EORTC QLQ HN 43 questionnaire. Thirty patients were assessed, in which 12 had gastric pull-ups, 16 had free jejunum flaps, and 2 had free anterolateral thigh flaps. There was a 38% five-year survival rate. Overall, the rates of stricture (10.7%) and fistula (7.1%) were low. The majority of patients (53.6%) returned to a normal diet within three months with a soft or puree diet in 35.7% of patients. Some form of speech was possible in 92.9% of patients. The average questionnaire score for surviving patients was 87.3, with good outcomes related to eating and swallowing, but poorer outcomes for speech and communication. This study showed that outcomes for patients receiving complex reconstruction following hypopharyngeal tumour resection are improving over time. There is still scope for improvement of patient outcomes and refinement of optimum surgical management strategies.

Purpose: The adenoids, or pharyngeal tonsils, consist of a pad of lymphoid tissue, located on the posterior pharyngeal wall of the nasopharynx. During childhood, the adenoid pad serves as a contact site for the soft palate to assist with velopharyngeal closure during oral speech. During adenoidal involution, most children are able to maintain appropriate velopharyngeal closure necessary for normal speech resonance. The purpose of this study is to determine age-related trends of normal adenoid growth and involution from infancy through adulthood. Method/Description: Lateral view magnetic resonance imaging was used to analyze velopharyngeal variables among 270 participants, between 3 months and 34 years of age. The velopharyngeal measures of interest included velar length, effective velar length, pharyngeal depth, adenoid height, adenoid thickness, adenoid depth, and adenoid area. Participants were divided into four age groups for statistical comparison. Results: There was a statistically significant difference ( p < .05) in all linear and area measurements between the four age groups. Adenoid depth reached peak growth at age 4 years, whereas adenoid height and adenoid thickness peaked at 8 years of age. Qualitatively, adenoid growth progresses in an anterior and inferior direction whereas involution occurs in a posterior and superior direction. Conclusions: This study contributes to the knowledge of time specific changes across an age span for adenoid growth and involution and presents a visualization of the shape and growth trends of adenoids. A new sequence of involution is reported beginning first with adenoid depth, followed by adenoid height at a slightly faster rate than adenoid thickness.

The goal of this study was to determine whether a relationship exists between the amount of mandibular setback and the amount of airway dimensional changes. Records and cone beam computed tomography (CBCT) of patients who had undergone isolated bilateral sagittal split osteotomy setback between January 1, 2013 and March 16, 2020 at a single institution were reviewed retrospectively. The primary outcome variable was upper airway volume dimension change, and the predictor variable was the magnitude of mandibular setback as measured by six different methods. Thirty-one patients were included in the study, with a mean mandibular setback ranging from 1.41 mm to 6.11 mm. None of the predictor variables showed an association with oropharyngeal (P = 0.54) or hypopharyngeal (P = 0.33) volume. Stepwise regression analysis failed to show any significant relationships. Similarly, there was no statistically significant association between any of the predictor variables and oropharyngeal (P = 0.44) or hypopharyngeal (P = 0.74) minimum axial area. The results showed that no correlation exists between the magnitude of mandibular setback and the amount of static airway dimensional changes; therefore, it may not be possible to predict whether obstructive sleep apnea will develop following mild to moderate mandibular setback based upon CBCT measurements.

Nuove patologie endemiche e pandemiche con trasmissione aerea interumana attraverso siti anatomici di orecchio, naso e gola.L’attuale pandemia di SARS-CoV-2 ha ancora una volta stigmatizzato l’importanza dei patogeni respiratori e il loro impatto clinico, sociale e di salute pubblica. I virus respiratori si trasmettono tra gli individui quando l’agente patogeno viene rilasciato dalle vie aeree superiori o dal tratto respiratorio inferiore di un individuo infetto. La trasmissione per via aerea è definita come l’inalazione di particelle aereosolizzate infette di dimensioni inferiori a 5 mm, che può essere inalato a una distanza fino a 2 metri. Questo modo di trasmissione è rilevante per gli agenti patogeni respiratori virali, tra cui il coronavirus della sindrome respiratoria acuta grave (SARS-CoV), la sindrome respiratoria del Medio Oriente (MERS)-CoV, il virus dell’influenza, il rinovirus umano, il virus respiratorio sinciziale (RSV) e altre famiglie di virus respiratori che differiscono per strutture virali e genomiche, suscettibilità delle popolazioni all’infezione, gravità, trasmissibilità, modi di trasmissione e ricorrenza stagionale. Questi virus respiratori umani generalmente infettano le cellule del tratto respiratorio superiore, suscitando segni e sintomi respiratori, a volte senza la possibilità di essere differenziati clinicamente. Come evidenziato dall’attuale pandemia di COVID-19, i virus respiratori umani possono sostanzialmente contribuire ad aumentare la morbilità e la mortalità, con un notevole impatto sociale ed economico. In questo articolo, descriviamo gli aspetti strutturali, clinici e di trasmissione dei principali virus respiratori responsabili di infezioni endemiche, epidemiche e pandemiche.The current severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has once again stigmatised the importance of airborne pathogens and their clinical, social and public health impact. Respiratory viruses are transmitted between individuals when the pathogen is released from the upper airways or from the lower respiratory tract of an infected individual. Airborne transmission is defined as the inhalation of the infectious aerosol, named droplet nuclei which size is smaller than 5 mm and that can be inhaled at a distance up to 2 metres. This route of transmission is relevant for viral respiratory pathogens, including severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome (MERS)-CoV, influenza virus, human rhinovirus, respiratory syncytial virus (RSV) and other respiratory virus families that differ in viral and genomic structures, susceptibility of a population to the infection, severity, transmissibility, ways of transmission and seasonal recurrence. Human respiratory viruses generally infect cells of the upper respiratory tract, eliciting respiratory signs and symptoms, sometimes without the possibility to differentiate them clinically. As seen by the current Coronavirus Disease 2019 (COVID-19) pandemic, human respiratory viruses can substantially contribute to increased morbidity and mortality, economic losses and, eventually, social disruption. In this article, we describe the structural, clinical and transmission aspects of the main respiratory viruses responsible for endemic, epidemic and pandemic infections.

The objective of this study was to investigate the morphological changes of the upper airway and the position of the hyoid bone in hyperdivergent adults with different mandibular lengths after premolar extraction.The data of 57 hyperdivergent adults, aged 20-35 years, who had 4 premolar extractions were included for the study. Mandibular length (CoGn) was used for grouping (A: long CoGn, B: short CoGn). Pretreatment and posttreatment lateral cephalograms and cone-beam computed tomography images were used to assess the position of mandible, hyoid bone, and upper airway using paired t test. An independent sample t test was used to detect changes of the airway and hyoid position between groups A and B. Pearson correlation analysis was applied to estimate the correlation between pharyngeal spaces and dentoskeletal morphology at P 0.05.In all subjects, we observed retraction of the upper incisors, mesial movement of the lower molars, and reduction of the mandibular planes. In group A, differences were found in anterior and posterior movements of the hyoid bone, increase of airway volume, minimum cross-sectional area (MCA) and anteroposterior linear distance (APL) (P 0.05). There were notable differences in the change of hyoid position, airway volume, MCA, and APL between group A and group B. Glossopharyngeal and hypopharyngeal volumes, MCA, and APL were correlated with articular angle, mandibular plane, and hyoid bone position (P 0.05).With a comprehensive diagnosis and treatment, premolar extraction in hyperdivergent adults with favorable CoGn can facilitate improvement of esthetics, hyoid bone position, and the increase in glossopharyngeal and hypopharyngeal volumes and MCA.

Il rischio di contagio da SARS-CoV-2 tra gli specialisti in otorinolaringoiatria.La malattia da COVID-19 si è rapidamente diffusa negli ultimi due anni con un forte impatto sull’attività otorinolaringoiatrica, che ha subito una radicale trasformazione per garantire assistenza principalmente a pazienti oncologici e urgenti, e assicurare protezione al personale sanitario e ai pazienti. Durante le fasi iniziali della pandemia, le visite programmate e gli interventi chirurgici elettivi sono stati posticipati, spesso causando un ritardo nella diagnosi e nel trattamento di diverse condizioni, anche oncologiche, con diagnosi in fasi di malattia avanzata e trattamenti più aggressivi. L’aerosol e le goccioline di saliva sono la principale via di trasmissione del virus SARS-CoV-2. Pertanto, l’uso corretto dei dispositivi di protezione individuale (DPI) e l’attenzione ai rischi e alle misure di protezione specifiche per ogni procedura otorinolaringoiatrica sono della massima importanza. In conclusione, questa review evidenzia che l’attività otorinolaringoiatrica implica un alto rischio di contagio in occasione di visite, interventi chirurgici o trattamento di condizioni urgenti. Il corretto utilizzo dei DPI, la valutazione dei rischi specifici di ogni procedura e la riduzione di visite e interventi non urgenti sono considerate le principali strategie per limitare il contagio.COVID-19 has rapidly spread in the past two years with a profound impact on otolaryngological activities, which has undergone radical transformation to guarantee diagnostic and therapeutic procedures mainly in oncology and urgent patients, while ensuring protection for healthcare personnel and patients. During the initial phases of the pandemic, scheduled visits and elective surgeries were postponed leading to a delay in the diagnosis and treatment of several diseases, including head and neck cancer, with a shift toward more advanced cancer stages and more aggressive treatments. Aerosol and droplets are the main routes of transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), thus leading to a high risk of contagion during otolaryngology visits and surgery. Therefore, the correct use of personal protective equipment (PPE) and attention to procedure-specific risks and measures to avoid contagion are of utmost importance for healthcare professionals, and especially for those dealing with otolaryngology diseases. This narrative review highlights that otolaryngological activity implies a high risk of contagion during outpatient visit, surgery, or urgent conditions. The correct use of PPE, evaluation of procedure-specific risks and reduction of non-urgent procedures are considered the main strategies to limit contagion.

During the Coronavirus Disease 2019 (COVID-19) pandemic, otolaryngology has been shown to be a high-risk specialty due to the exposure to aerosol-generating physical examinations, procedures and surgical interventions on the head and neck area, both in adult and paediatric patients. This has prompted the issue of updating the guidelines by International Health Authorities in the Ear Nose and Throat (ENT) field and, at the same time, has stimulated engineers and healthcare professionals to develop new devices and technologies with the aim of reducing the risk of contamination for physicians, nurses and patients.A review of the literature published on PubMed, Ovid/Medline and Scopus databases was performed from January 01, 2020 to December 31, 2021.73 articles were eligible to be included, which were subdivided into 4 categories: ("Artificial Intelligence (AI)"; "Personal Protective Equipment (PPE)"; "Diagnostic tools"; "Surgical tools").All of the innovations that have been developed during the COVID-19 pandemic have laid the foundation for a radical technological change of society, not only in medicine but also from a social, political and economical points of view that will leave its mark in the coming decades.Innovazioni diagnostiche e chirurgiche in otorinolaringoiatria per i pazienti adulti e pediatrici durante l’era COVID-19.Durante la pandemia da COVID-19, l’otorinolaringoiatria ha dimostrato di essere una delle specialità a più alto rischio di contatto con le malattie virali a trasmissione aerea, a causa dell’esposizione a procedure generanti aerosol sul distretto testa-collo, sia sul paziente adulto che pediatrico. Questo ha rappresentato il punto di partenza non solo per l’emanazione di nuove linee guida da parte delle Società scientifiche internazionali, ma ha anche stimolato l’inventiva di tecnici e operatori sanitari nello sviluppare nuovi dispositivi e tecnologie per ridurre il rischio di contaminazione per gli operatori sanitari e per il paziente.È stata eseguita una revisione della letteratura dal giorno 1 gennaio 2020 al 31 dicembre 2021 utilizzando i database di PubMed, Ovid/Medline e Scopus.Sono stati selezionati 73 articoli e raccolti in 4 categorie differenti (“Intelligenza Artificiale”; “Dispositivi di Protezione Individuale”; “Strumenti diagnostici”; “Strumenti chirurgici”).Le innovazioni sviluppate durante la pandemia da COVID-19 hanno posto le basi per una trasformazione in ambito tecnologico di tutta la società, non solo da un punto di vista medico ma anche da un punto di vista sociale, politico, ed economico, riflettendosi in una trasformazione che segnerà la mentalità dell’intera popolazione mondiale per i prossimi decenni.

A 37-year-old man presented to the ENT outpatient clinic with progressive dysphagia and breathlessness on exertion for a year. The patient was tachypnoeic, with mild inspiratory stridor and orthopnoea. The neck had a generalised swelling, but no mass was clinically palpable. Indirect laryngoscopy

A 37-year-old man with no known comorbidities presented to our department with complaints of left eye proptosis and diminution of vision for 1 month and left facial swelling for the past 2 years. He underwent left-sided nasal surgery thrice—functional endoscopic sinus surgery (FESS) in 2018

A previously healthy 26-year-old man presented with 1-month history of right-sided neck swelling. According to him, the swelling progressively increased in size over 1 week and concurrently became red and painful. There was no dysphagia or odynophagia. He denied recent fever, upper respiratory

From the first days of life, a female newborn suffered from nasal congestion and a runny nose. The first MRI, at 42 days of life, revealed a solid and expansive mass of 1 cm in the left nasal fossa. The radiological examination repeated at 4 months of life showed an increase in volume, up to 2 cm (

A 20-year-old man presented to the emergency department with a sore throat and general malaise for 2 days. On evaluation, an incidental bifurcated uvula was noted without any acute oropharyngeal abnormalities ([figure 1][1]). He reported the bifurcated uvula was likely congenital as his parents

The constrictor pharyngis superior (CPS) initially develops along the posterior wall of the pharyngeal mucosal tube, whereas, during the early phase, the buccinators (BC) are far anterolateral to the CPS. The process and timing of their meeting during fetal growth have not been determined.The topographical relationship between the growing BC and CPS was assessed in histological sections from 22 early- and mid-term fetuses of approximate gestational age (GA) 8-16 weeks, and eight late-term fetuses of approximate GA 31-39 weeks.At 8-9 weeks, the palatopharyngeus appeared to pull the CPS up and forward. Until 11 weeks, the CPS was attached to the hamulus of the pterygoid (pterygopharyngeal part). Until 13 weeks, the CPS extended anterolaterally beyond the hamulus to meet the BC. Some BC muscle fibers originated from the oral mucosa. Notably, by 30 weeks, the CPS-BC interface had become covered by or attached to the palatopharyngeus. Muscle fibers of the palatopharyngeus, however, were thinner than those of the CPS and BC. At and near the interface, BC muscle fibers tended to run along the left-right axis, whereas those of the CPS ran anteroposteriorly. A definite fascia (i.e., a future pterygomandibular raphe) was usually absent between these muscles in fetuses.The excess anterior growth of the CPS with its subsequent degeneration might cause individual anatomical variations in composite muscle bundles of the palatopharyngeus-CPS complex or palatopharyngeal sphincter. A tensile transduction from the BC to the CPS through the raphe seemed unnecessary for cooperative suckling and swallowing after birth.
