To determine the indications, anesthesiological and surgical procedure and interest of drug-induced sleep endoscopy in the treatment of adult obstructive sleep apnea syndrome. A redactional committee of 17 experts was set up. Conflicts of interest were disclosed and followed up throughout the process of drawing up the guidelines. The work received no funding from any firm dealing in health products (drugs or devices). The GRADE (Grading of Recommendations Assessment, Development and Evaluation) method was applied to assess the quality of the data on which the guidelines were founded. It was stressed that strong recommendations should not be made on the basis of poor-quality or insufficient data. The committee studied 29 questions on 5 topics: indications and contraindications, anesthetic technique, surgical technique, interpretation and reporting of results, and management guided by results. Expert review and application of the GRADE method led to 30 guidelines: 10 with high level of evidence (Grade 1+ or 1−), 19 with low level (GRADE 2+ or 2−) and 1 expert opinion. Experts fully agreed on the strong guidelines formalizing the indications and modalities of drug-induced sleep endoscopy for adult obstructive sleep apnea syndrome. [ABSTRACT FROM AUTHOR]

Drug-induced-sedation endoscopy (DISE) has proved superior to awake clinical examination for diagnosis of upper-airway obstruction sites and surgical planning. Our question is: does multilevel obstruction on DISE systematically entail failure for surgery limited to the upper pharynx? We conducted a retrospective single-center study in patients with obstructive sleep apnea syndrome (OSAS) treated by single-level surgery of the upper pharynx (tonsillectomy with or without pharyngoplasty). Preoperative assessment included polysomnography (PSG) and DISE. Surgical efficacy was assessed on postoperative PSG. Treatment response was defined by postoperative apnea-hypopnea index (AHI) < 20 events/h with 50% reduction, and cure by AHI < 10 (patients with preoperative AHI ≤ 10 being excluded). Efficacy was compared between groups without (group A) and with basilingual or laryngeal collapsus on DISE (group B). We analyzed 63 patients, with mean preoperative AHI 33.8 ± 17.9 events/h. The two groups (A, n = 36; B, n = 27) were clinically comparable. Postoperative PSG took place at a mean 8.5 ± 11.5 months. The success rate was 66.7% in group A (mean reduction in AHI, 57.3 ± 36.2%) and 59.3% in group B (mean reduction, 53.9 ± 39.2%). Cure rates were respectively 48.5% and 48.1%. There was no statistically significant difference between the two groups (P > 0.1). Oropharyngeal surgery can alleviate associated obstructive sites found on DISE in the lower pharynx, and step-by-step treatment shows efficacy equal to that of single-step multilevel surgery.

Early glottic carcinoma is currently managed by radiation therapy or endoscopic surgery. Both are effective in elderly patients, but their respective indications are poorly determined. The present study assessed our management of very elderly patients with early glottic carcinoma. A retrospective single-center study included all patients aged 75 years and older at diagnosis, treated by radiation therapy or endoscopic surgery with curative intent for T1 or T2 glottic carcinoma between 2004 and 2018. Records of 33 patients (27 men and 6 women; mean age, 82.2 years (range, 76.1-93.1 years)) were reviewed. 24 patients received radiation therapy and 9 endoscopic resection. The only factor for choice of treatment was anterior commissure involvement. Overall survival was 87% at 2 years and 62% at 5 years. 19% of patients relapsed within 5 years and had to undergo further treatment. There were no treatment-related deaths. Radiation therapy was associated with more acute local complications, with two temporary treatment interruptions and one uncompleted treatment. Surgical treatment was more likely to result in dysphonia, found in 80% of cases. Treatment of early glottic cancer in elderly subjects can consist in either radiotherapy or endoscopic surgery. Age should not affect management. Surgical treatment is shorter and better tolerated, although with poorer vocal outcome, and may be preferred in the most comorbid patients. [ABSTRACT FROM AUTHOR]

Abstract Objectives/Hypothesis The retrolingual space is one of the potential sites of obstruction identified in patients with obstructive sleep apnea syndrome (OSAS). Hypertrophied lingual tonsils (LT) can obstruct the airway at this level. The goal of this study was to measure the tolerance and efficacy of lingual tonsillectomy in patients with OSAS. Study design A retrospective chart review was conducted recruiting all patients with OSAS confirmed on sleep recording, who either had failed or refused medical treatment and who underwent lingual tonsillectomy. Materials and methods Diagnosis of LT hypertrophy was made by full ENT clinical examination using a flexible endoscopy, completed by MRI and followed by drug-induced sleep endoscopy. The surgical intervention was carried out endoscopically by diode laser or coblation. The primary endpoint to measure efficacy was drop in apnea-hypopnea index (AHI) on sleep recording at 6 months. Secondary endpoints comprised reduced snoring and Epworth Sleepiness Scale (ESS) and postoperative symptom tolerance. Results Eleven patients aged 44.3 ± 12.6 years were included. AHI dropped from 29.5 ± 21.7/h to 11.6 ± 9.6/h: i.e., by 60% (P = 0.005). Five patients had AHI < 10/h: i.e., cure rate of 45%. ESS dropped from 13 ± 3.4 to 8.1 ± 4.9 (P = 0.012). No complications were observed. Conclusions LT ablation seemed effective in OSAS with retrolingual obstruction in failure of medical treatment. Level of evidence 4. [ABSTRACT FROM AUTHOR]

Free fibula transplant is routinely used for mandibular reconstruction in head and neck cancer. Dental rehabilitation, the objective of mandibular reconstruction, requires the use of dental implants as supports for fixed or removable dentures. Positioning of fibular bone grafts and implants determines implant osseointegration and the possibilities of dental rehabilitation. Prefabrication of a fibula free flap with dental implants prior to harvesting as a free flap can promote implant osseointegration. The position of the implants must then be precisely planned. Virtual surgery and computer-assisted design and prefabrication techniques are used to plan the reconstruction and then reproduce this planning by means of tailored fibula and mandible cutting guides, thereby ensuring correct positioning of fibular bone fragments and implants. The prefabricated fibula free flap technique requires two surgical procedures (prefabrication and flap transfer) and precise preoperative planning. Prefabricated fibula free flap with dental implants, by improving the quality of osseointegration of the implants before flap transfer, extends the possibilities of prosthetic rehabilitation in complex secondary mandibular reconstructions.

Surgical results in obstructive sleep apnea syndrome (OSAS) vary greatly, whatever the surgical technique or site treated. Most authors agree that rigorous patient selection is logical and mandatory. Drug-induced sleep endoscopy (DISE) was introduced in 1991 and has been rediscovered and used extensively since the 2000s. It mimics sleep in order to observe the upper airway on flexible endoscopy. A review of the DISE literature was performed, and is reported in two parts. The present first part describes the technique: drugs, practical anesthesiologic and ENT modalities, reproducibility, and limitations. [ABSTRACT FROM AUTHOR]

Surgical results in obstructive sleep apnea syndrome (OSAS) vary greatly, whatever the surgical technique or site. Most authors agree that rigorous patient selection is logical and mandatory. Drug-induced sleep endoscopy (DISE) was introduced in 1991 and has been rediscovered and used extensively since the 2000s. It attempts to mimic natural sleep in order to observe the upper airway on flexible endoscopy in a situation in which obstruction may occur. A review of the DISE literature was performed, and is reported in two parts. The present second part reports DISE results concerning obstruction sites, impact on treatment efficacy and the consequent indications for this exploration. [ABSTRACT FROM AUTHOR]

Due to the complex anatomy of the head and neck, a wide range of pedicled or free flaps must be available to ensure optimal reconstruction of the various defects resulting from cancer surgery. The supraclavicular artery island flap is a fasciocutaneous flap harvested from the supraclavicular and deltoid regions. The blood supply of this flap is derived from the supraclavicular artery, a direct cutaneous branch of the transverse cervical artery in 93% of cases or the supraclavicular artery in 7% of cases. The supraclavicular artery is located in a triangle delineated by the posterior border of the sternocleidomastoid muscle medially, the external jugular vein posteriorly, and the median portion of the clavicle anteriorly. This pedicled flap is thin, malleable, and is easily and rapidly harvested with a reliable pedicle and minimal donor site morbidity. It can be used for one-step innervated reconstruction of many types of head and neck defects. It constitutes an alternative to local flaps, while providing equivalent functional results and must be an integral part of the cancer surgeon's therapeutic armamentarium. [ABSTRACT FROM AUTHOR]

Introduction Reconstruction of the oral cavity and oropharynx after tumour resection often involves the use of free flaps, but donor site morbidity must be taken into account. The radial forearm flap, the flap most commonly used in this setting, leaves a readily visible scar on an exposed region of the body. The thoracodorsal artery perforator flap (TDAP), which possesses the same plastic qualities as the radial forearm flap, leaves a scar that is hidden in the axilla. The purpose of this study was to evaluate the cosmetic results of radial forearm and thoracodorsal artery perforator free flap donor sites. Material and methods The medical charts of all patients undergoing reconstruction by a radial forearm or thoracodorsal artery perforator free flap between January 2011 and December 2011 were retrospectively reviewed. The Patient and Observer Scar Assessment Scales and the Vancouver Scar Scale were used to evaluate the quality of the scars. Results Reconstruction was performed by radial forearm flap in 4 cases and TDAP flap in 7 cases. The PSAS score was significantly lower in the TDAP group than in the radial forearm group ( P = 0.03), and the OSAS score was higher in the radial forearm group (21.5 versus 14). The Vancouver Scar Scale was significantly higher for radial forearm flap scars than for TDAP scars (8 versus 2.7, P = 0.005). Conclusion This is the first study to compare radial forearm and thoracodorsal artery perforator free flap donor site scars. It demonstrates the minimal TDAP donor site morbidity and the high level of patient satisfaction. [ABSTRACT FROM AUTHOR]

The present study sought to describe clinical presentation in extranodal lymphoma of the head and neck (ELHN), with the aim of improving diagnostic management. Material and methods A single-center retrospective observational study was conducted over the period 2001–13. Age, gender, histologic type, location, type of clinical presentation, time interval between symptom onset and histologic diagnosis and presence of specific symptoms were recorded, as were the specialty of the physician initially consulted and of the physician taking the diagnostic sample. Results Sixty-seven cases of ELHN were diagnosed: 39 male and 28 female patients, with a median age of 68 years. B-cell lymphoma (84%) was more frequent than plasmacytoma (7%) or T-cell lymphoma (6%). Location was mainly palatine tonsil (28%), nasal fossa and sinus (19%), nasopharynx (14%) or parotid (13%). Revelation often involved a mass (33%), and only rarely any specific symptoms (9%). Time interval from symptom onset to diagnosis was short in aggressive lymphoma and longer in low-grade lymphoma (mean 4 and 10 months respectively). The physician initially consulted was an ENT specialist in 67% of cases, and an ENT specialist performed diagnostic sampling in 97% of cases. Conclusion ELHN is a rare pathology (5 cases per year in our department) of highly variable clinical presentation depending on location and histologic type. The ENT physician should be prepared for diagnosis regardless of anatomic location, so as to optimize diagnostic management. [ABSTRACT FROM AUTHOR]

Abstract: Objective: To determine the long-term (>3 years) outcome of patients suffering from simple snoring or non-severe obstructive sleep apnea syndrome (OSAS) treated by radiofrequency ablation of the soft palate. Study design: Observational retrospective study. Setting: Tertiary care university hospital. Subjects and methods: Seventy-seven subjects were included between 1999 and 2006. Twenty-seven suffered from mild or moderate OSAS. All patients were treated by radiofrequency-assisted stiffening of the soft palate, with or without uvulectomy. Snoring (assessed on a 10cm visual analog scale (VAS)), marital status, presence of cardiovascular risk factors or pathologies and follow-up time were evaluated by postal questionnaire. Results: Mean follow-up time was 6.3±2.3 years. Mean snoring intensity decreased significantly in the immediate postoperative period (8.1±2.9 to 3.5±2.2cm on VAS). Over the longer term, however, we observed a significant increase in snoring intensity (5.7±2.9cm), which nevertheless remained below the preoperative values (P <0.001). Bed-partners noticed a relapse of snoring in 92.7% of cases. Nine percent of couples separated. Hypertension and diabetes were diagnosed during follow-up in 12.1% and 6.6% of the subjects, respectively. A majority of patients failed to undergo repeat polysomnography or further treatment. Conclusion: Relapse of snoring was observed in nearly all patients in the long run, although intensity appears to remain lower than preoperatively. Most patients did not comply with the follow-up instructions and did not seek other forms of treatment when recurrence occurred. [Copyright &y& Elsevier]

Summary: Background: Craniofacial fibrous dysplasia has not only esthetic but functional impact. Surgery is controversial, ranging from conservative to radical. It involves elevated hemorrhage risk, and should be progressive, based on an individual risk/benefit analysis with the aim of improving quality of life. Case reports: Three patients (one male, two female; mean age, 35years) with evolutive orbital-temporal maxillary dysplasia were treated between 2008 and 2009 in our department. All showed exophthalmia and nasal obstruction. In one patient, symptomatology was aggravated by a frontal sinus cyst within the dysplasia. Another had associated auditory canal obstruction inducing recurrent external otitis. Optic nerve decompression was achieved on a combined coronal and endonasal approach, assisted by neuronavigation. Complementary remodelling resection, dacryocystorhinostomy and internal optic nerve decompression were performed. Functional results showed 70 % improvement on a subjective scale for eye tension and nasal obstruction. Surgery was feasible in all patients, with no complications. Conclusion: Current surgical management allies esthetic and functional concerns. Remodeling resection is the reference technique. The coronal approach is a good primary option for optic nerve decompression. Endonasal surgery with neuronavigation improves nasal ventilation and lacrimal canal permeability.

PURPOSE: Cephalometry can be helpful for choosing the optimal treatment of sleep apnea. The presence or absence of maxillomandibular retrusion can contribute to the choice of treatment with an oral appliance or a skeleton-based or soft tissue surgery. To measure the position of the maxillomandibular complex, the analysis of Tweed has been cited most often. It uses dental landmarks. The analysis of Delaire relies on deeper skeletal points. The present study compared these 2 analyses for the diagnosis of maxillomandibular retrusion in a context of sleep-disordered breathing by determining the correlation between retrusion and the apnea-hypopnea index (AHI) for both methods. MATERIALS AND METHODS: A retrospective cohort study was conducted in a tertiary care university hospital. The population consisted of patients diagnosed with sleep-disordered breathing for whom polysomnographic and cephalometric data were available. Tweed and Delaire cephalometric analyses were performed for each case. The main outcome was the correlation between the degree of maxillomandibular retrusion and the AHI, as determined by Pearson coefficients. RESULTS: A total of 243 patients (42 females and 201 males) were included. For maxillary retrusion, the correlation coefficient with the AHI was -0.109 (P = .089) for Tweed and -0.160 (P = .012) for Delaire. For mandibular retrusion, the coefficient was -0.090 (P = .16) for Tweed and -0.201 (P = .002) for Delaire. Statistical significance was found only for the analysis of Delaire. CONCLUSION: The correlation between maxillomandibular retrusion and the AHI was better using the analysis of Delaire. If cephalometry is to be included in the workup of sleep-disordered breathing, the analysis of Delaire might be preferable. [ABSTRACT FROM AUTHOR]

Summary: Neck pain affects a third of patients following head-and-neck cancer treatment, whether by radiation therapy or surgery. It is a disabling condition and the associated muscle contractures impair cervical motion. Type-A botulinum toxin is an analgesic and muscle relaxant, able to improve patients’ quality of life. We here report our experience with botulinum toxin in post-radiosurgical neck contracture. Patients and methods: A single-center pilot study was run from January 2007 to July 2008, respecting the Declaration of Helsinki. All patients in complete remission from head-and-neck cancer with post-radiosurgical neck contracture impairing neck motion were included. Pain and functional impairment were assessed on a neck-function disability scale before and 1 month after botulinum toxin injection. Efficacy duration was measured. Complications at the injection site or related to drug diffusion were investigated. Results: Nine consecutive patients (six male, three female; mean age, 61 years [range, 52–73 years]) were included. In six patients, the sternocleidomastoid muscle was injected and the muscular pedicle of a pectoralis major flap in three. Mean cervical disability score fell significantly from 33 to 23 (P =0.01). There were no complications. Efficacy was seen at a mean 6 days, and analgesia and muscle relaxation lasted for a mean 19 days. Conclusion: In post-radiosurgical neck contracture, botulinum toxin injection is a simple and easy procedure able to improve neck motion and reduce neck pain in head-and-neck cancer patients. A phase-II prospective study to determine injection sites and dosage should help bear out these preliminary findings. [ABSTRACT FROM AUTHOR]

Summary: Objectives: The use of microanastomosed free flaps has become essential in the management of head and neck defects following cancer resection or other causes. However, this surgery is under-rated by the French case-mix based rating procedure. The purpose of this study was to evaluate the cost balance of this type of surgery in a patient cohort managed by free flap head and neck reconstruction in a polyvalent adult head and neck surgery department. Material and methods: This retrospective study was based on 52 patients divided into two groups undergoing either mandibular or nonmandibular reconstruction. Possible prognostic factors were investigated in patients undergoing mandibular reconstruction. Kaplan-Meier survival analysis was also performed for both groups of patients. The Foch Hospital financial department''s analytical accounting data for 2006 and 2007 were used to evaluate the costs related to these patients. A senior surgeon retrospectively reviewed the patients’ charts with the Medical Informatics physician in order to optimize the choice of diagnosis-related group (DRG). Results: The mean income generated by mandibular and nonmandibular reconstructions in 2006 and 2007 was 545€/day and 526€/day for hospitalisation including free flap and 828€/day and 818€/day for “satellite” hospitalisations for other procedures related to the reconstruction, respectively. After review of the rating by a senior surgeon, in order to optimize the choice of DRG, the mean income received by the hospital could have been improved by +6%. Conclusion: Optimization of procedure and hospital stay rating associated with better collaboration with the Medical Informatics physician are essential in order to continue to provide this major surgery, which is essential for the patient''s quality of life. A higher rating of this activity by the French health system is also necessary. [Copyright &y& Elsevier]

Summary: Introduction: Salivary duct carcinoma (SDC) is an uncommon entity of salivary gland cancers with a poor prognosis due to local aggressiveness or distant recurrences involving lymph nodes, lung, and long bones, in which secondary lesions are usually osteolytic. The authors report the first case of mandibular SDC, atypical due to its osteosclerotic presentation and its site, attributed to aggressive neural spread of the tumor along the trigeminal nerve. Case study: This asymptomatic osteosclerotic bone involvement was diagnosed based on pathological enhancement of the trigeminal nerve demonstrated on MRI and was accompanied by facial nerve involvement up to its third intracranial portion. Radical surgery ensured disease control with continued good quality of life at the 4-year follow-up visit. Conclusion: Nerve enhancement on MRI and determination of specific tumor markers (HER-2/neu and p53) should be taken into account to evaluate the prognosis of SDC and to propose appropriate surgical treatment.

Summary: Introduction: Obstructive sleep apnea syndrome (OSAS) may be suspected at interview, notably in case of snoring. Various studies suggested a link between primary open angle glaucoma (POAG) and OSAS. The present study sought to determine OSAS prevalence in POAG associated with snoring. Material and methods: Thirty-one snoring glaucomatous patients prospectively underwent simplified polysomnography. Ophthalmologic examination ruled out secondary glaucoma and assessed the glaucomatous neuropathy. Results: 49% of the patients included were diagnosed with OSAS. Ophthalmologically, glaucoma showed no specific characteristics. Conclusion: Given the high-prevalence of OSAS in patients with POAG, presence of snoring should be explored at interview. Conversely, patients who snore should be asked whether they have POAG, and if so, should undergo all-night sleep recording to explore for OSAS. [ABSTRACT FROM AUTHOR]

During the 2017 IFOS ENT World Congress, an international expert panel was asked to clarify the role of ENT in the diagnosis process of the obstructive sleep apnea syndrome (OSA) in adults around the world. OSA is a major public health issue throughout the world. OSA is a highly prevalent disease with heavy clinical, social and economical outcomes. This high prevalence raises serious difficulties of diagnosis accessibility if only somnologists are able to confirm OSA diagnosis. First of all, the panellists reviewed the impact of OSA. Secondly, they defined the ENT role stressing ENT legitimacy, professional expertise and academic and institutional tasks. They also defined when somnologists were necessary. For the international panel, the ENT is a major player in the OSA diagnosis process. [ABSTRACT FROM AUTHOR]
