Guidelines of the French Society of ENT (SFORL): Drug-induced sleep endoscopy in adult obstructive sleep apnea syndrome.

OBJECTIVES: To determine the indications, anesthesiological and surgical procedure and interest of drug-induced sleep endoscopy in the treatment of adult obstructive sleep apnea syndrome. DESIGN: 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. METHODS: 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. 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. CONCLUSION: Experts fully agreed on the strong guidelines formalizing the indications and modalities of drug-induced sleep endoscopy for adult obstructive sleep apnea syndrome.

Does advanced age affect treatment of early glottic carcinoma?

AIMS: 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. MATERIAL AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.

OSAS and upper pharynx surgery: Does basilingual collapsus always rhyme with failure?

OBJECTIVE: 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? MATERIAL & METHODS: 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). RESULTS: 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). CONCLUSIONS: 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.

Surgical ablation of lingual tonsils in the treatment of obstructive sleep apnea.

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.

Prefabricated fibula free flap with dental implants for mandibular reconstruction.

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.

International consensus (ICON) on the ENT role in diagnosis of obstructive sleep apnea syndrome.

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.

Drug-induced sleep endoscopy: A new gold standard for evaluating OSAS? Part I: Technique.

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.

Drug-induced sleep endoscopy: A new gold standard for evaluating OSAS? Part II: Results.

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.

Supraclavicular artery island flap in head and neck reconstruction.

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.

Comparison of radial forearm flap and thoracodorsal artery perforator flap donor site morbidity for reconstruction of oral and oropharyngeal defects in head and neck cancer.

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.

Extranodal lymphoma of the head and neck: a 67-case series.

UNLABELLED: 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.

Velopharyngeal function after free thoracodorsal artery perforator flap in lateral and superior oropharyngeal cancer.

The purpose of this study was to report our experience with the free thoracodorsal artery perforator flap for reconstruction of the oropharynx and soft palate in head and neck cancer using a retrospective review of the medical charts of all patients undergoing oropharyngeal reconstruction by free thoracodorsal artery perforator flap during the same procedure as cancer resection between January 2011 and April 2013. Evaluation of speech, feeding and the presence of nasal emissions was performed 6 months after treatment in accordance with the Declaration of Helsinki. Nine patients were evaluated. Clear understanding of the patient was reported by the family and the examiner for seven patients, while understanding difficulties were reported for two patients (1 case of flap dehiscence and 1 technical error of flap fixation). The results indicated that, due to its complex anatomy and function, reconstruction of the soft palate remains a delicate procedure. The free thoracodorsal artery perforator flap allows functional soft palate reconstruction, while limiting donor site morbidity.

Radiofrequency of the soft palate for sleep-disordered breathing: a 6-year follow-up study.

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 10 cm 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 ± 2.2 cm on VAS). Over the longer term, however, we observed a significant increase in snoring intensity (5.7 ± 2.9 cm), 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.

Craniofacial fibrous dysplasia surgery: a functional approach.

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, 35 years) 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.

Botulinum toxin in the treatment of post-radiosurgical neck contracture in head and neck cancer: a novel approach.

UNLABELLED: 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.
