Free-flap reconstruction methods in head-and-neck oncologic surgery: A CROSS practice survey of members of the French GETTEC Head-and-Neck Tumor Study Group.

OBJECTIVE: To survey practices concerning the use of anticoagulants and antiplatelets in microvascular free-flap reconstruction following oncological surgery of the head and neck. METHODS: A survey of practices was carried out between September 2022 and March 2023. An online questionnaire was sent to members of the French GETTEC Head-and-Neck Tumor Study Group in all French centers practicing head-and-neck cancer surgery with reconstruction using microvascular free-flaps. The questionnaire asked surgeons about their practices regarding the use of intra- and postoperative anticoagulants and antiplatelets, preoperative management of comorbidities, and prevention of postoperative complications. RESULTS: Sixty-one percent of the 38 respondents (23/38) used intraoperative intravenous heparin injection, associated to flap irrigation with heparin for 76% of surgeons (29/38) and/or a heparin solution bath for 37% (14/38). Postoperative anticoagulation was used by 95% of surgeons (36/38), and antiplatelets by 40% (15/38). Postoperatively, 40% (15/38) carried out monitoring using an implantable micro-Doppler probe, associated to analysis of clinical characteristics of the flap. CONCLUSION: Reconstructive surgery using microvascular free-flaps involves numerous factors that can influence success. Prospective studies, particularly concerning the management of anticoagulants, could enable a national consensus on methods for free-flap reconstruction.

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.

Speech restoration with tracheoesophageal prosthesis after total laryngectomy: An observational study of vocal results, complications and quality of life.

OBJECTIVES: To study voice prosthesis survival, complications, efficacy and impact on quality of life. METHODS: A single-center observational study was performed in patients treated for squamous cell carcinoma of the larynx or hypopharynx by total (pharyngo)-laryngectomy between 2010 and 2015. Study data comprised: maximum phonation time (sec), number of and reasons for prosthesis exchanges (leakage through or around the prosthesis, expulsion or inclusion of the prosthesis), plus 2 quality of life questionnaires (QLQ-C30, QLQ-H&N35) and the Voice Handicap Inventory (VHI 30). RESULTS: Forty-nine patients were included. The most common causes of prosthesis exchange were leakage through (73.2%) or around the prosthesis (18.5%). The median time between exchanges was 4 months. Global quality of life status on the QLQ-C30 was 63.5. Mean maximum phonation time was 7.4sec. Mean VHI was 46/120; 10 patients had a mild voice handicap, 12 moderate and 10 severe. No relation emerged between the number of prosthesis exchanges per year and quality of life. Voice handicap significantly decreased quality of life, with QLQ-C30 72.3 for the 22 patients with mild to moderate voice handicap and 44.2 for the 10 patients with severe voice handicap (P=0.001). CONCLUSION: Voice restoration by tracheoesophageal prosthesis after total (pharyngo)-laryngectomy is a reliable technique that decreases voice handicap and, despite potentially serious complications, has little negative impact on quality of life.

Medical analysis of the contribution of sialendoscopy in managing non-tumoral main salivary gland pathology in Reunion Island: Observational study following STROBE guidelines.

GOALS: To perform a medical analysis of the contribution of sialendoscopy in the treatment of non-tumoral pathologies of the main salivary glands, in Reunion Island, a French overseas territory. MATERIAL AND METHOD: A multicenter retrospective observational study was conducted for an 8-year period, before and after introduction of sialendoscopy (2011-2014 and 2015-2018), following STROBE guidelines. OBJECTIVES: To compare populations treated before (period A) and after (period B) the introduction of sialendoscopy in terms of clinical characteristics, and analyze the characteristics of patients treated by sialendoscopy. RESULTS: Two hundred and sixty-five patients were included: 74 in 2011-2014 and 191 in 2015-2018; 139 had sialendoscopy. Populations A and B were comparable except for the proportion of parotids treated (9% vs. 31%, respectively; P<0.0001), and smaller stones (11mm vs. 7.4mm, respectively; P=0.003). One hundred and ten pure sialendoscopies and 29 combined routes (20.8%) were performed: 63% submandibular and 37% parotid. Median age was 46 years. The M/F sex ratio was 0.96. Thirty-seven patients presented stenosis. There were 10 cases of papillary catheterization failure (7.1%), and 16 false routes or creation of false channels (11.5%), including 9 during the learning period. The rate of crossover to gland resection decreased: 10.45% for 2015-2016 and 5.56% for 2017-2018. CONCLUSION: Although follow-up ranged between 12 and 55months (median, 30months), sialendoscopy appeared to be a useful and reliable technique, with a role in therapeutic strategy for the management of non-tumoral salivary pathologies in Reunion Island.

Economic analysis of the contribution of sialendoscopy in managing non-tumoral principal salivary gland pathology in the Réunion Island: Economic evaluation following the CHEERS methodology.

GOALS: Cost analysis of the contribution of sialendoscopy in the treatment of non-tumoral pathologies of the main salivary glands, in Réunion Island, a French overseas territory. OBJECTIVES: Calculation and comparison of median pricing (i.e., median payment to the healthcare establishment) per patient before and after the introduction of sialendoscopy, in the only regional establishment practicing sialendoscopy and in the whole of Réunion Island. Material and method A multicenter retrospective cost study was conducted over an 8-year period, before and after the introduction of sialendoscopy (period A: 2011-2014 and period B: 2015-2018), according to the CHEERS guidelines for economic studies, and included inpatients with non-tumoral pathology of the main salivary glands, whether treated by sialendoscopy or not. RESULTS: Two hundred sixty-five patients were included, 139 of whom were treated by sialendoscopy: 74 in 2011-2014 and 191 in 2015-2018. Between the two periods, median pricing in the only center practicing sialendoscopy did not vary significantly: €3468 vs. €3368 (i.e., +2.9% (P=0.1)). In the Island as a whole, pricing increased significantly: €598 vs. €2332, (i.e., +390% (P<0.0001)). CONCLUSION: Sialendoscopy is cost-effective in France in the public healthcare sector if outpatient management is optimal, but significantly increases the public health budget. It makes it possible to recruit and manage previously untreated patients (small stones, salivary strictures, etc.).

Assessment of swallowing function after circumferential pharyngolaryngectomy. A multicenter study by the GETTEC group.

OBJECTIVE: Circumferential pharyngolaryngectomy is performed for advanced pharyngeal tumor or in a context of postradiation recurrence. Several free or pedicle flaps have been described for pharyngeal defect reconstruction, with choice at the surgeon's discretion. The aim of this study was to evaluate long-term swallowing function according to the type of flap used for reconstruction. MATERIAL AND METHOD: A multicenter retrospective study was conducted from January to September 2016 within the French GETTEC head and neck tumor study group. All patients in remission after circumferential pharyngolaryngectomy were included and filled out the Deglutition Handicap Index (DHI) questionnaire and underwent swallowing function fiberoptic endoscopy assessment. 46 patients (39 men, 7 women) were included. Reconstruction used a tubularized forearm free flap (FFF group) in 19 cases, pectoralis major myocutaneous flap (PMMF group) in 15 cases and free jejunum flap (FJF group) in 12 cases. RESULTS: Mean DHI was 24: 20 in the FFF group, 23 in the FJF group and 25 in the PMMF group, without significant differences. 27 patients had normal swallowing, 9 mixed diet, 8 liquid diet and 3 were fed by gastrostomy. On endoscopy, free flaps (FJF and FFF) were associated with significantly greater rates of normal swallowing of saliva and yogurt than in the PMMF group (P=0.04). CONCLUSION: Type of flap reconstruction after circumferential pharyngolaryngectomy had no significant impact on postoperative swallowing function assessed on the self-administered DHI questionnaire.

Nosocomial outbreak of Pseudomonas aeruginosa associated with a drinking water fountain.

Over a four-month period, ten patients were suspected of having acquired nosocomial infection to P. aeruginosa in the ear, nose, and throat department. Environmental and clinical isolates were compared. Only water from a drinking water fountain was contaminated by P. aeruginosa. This isolate and those of three patients had indistinguishable random amplified polymorphic DNA profiles. These patients had serious oncology diseases. The drinking water fountain was used for their alimentation by percutaneous endoscopic gastrostomy and was the origin of the outbreak. Another type of drinking fountain with a terminal ultraviolet treatment was installed, following which no new infections linked to drinking water were identified.

[Target volumes in cervical lympadenopathies of unknown primary: toward a selective customized approach? On behalf of REFCOR]. / Volumes cibles en radiothérapie des adénopathies cervicales de primitif inconnu : état des lieux et pistes vers une approche sélective raisonnée sous l'égide du Refcor (Réseau d'expertise français des cancers ORL rares).

The treatment of carcinomas of unknown primary revealed by cervical lymphadenopathy is based on neck dissection and nodal and pan-mucosal irradiation to control the neck and avoid the emergence of a metachronous primary. The aim of this review was to assess diagnostic and therapeutic approaches and criteria that may be used for a customized selective approach to avoid severe toxicities of pan-mucosal irradiation. A literature search was performed with the following keywords: cervical lymphadenopathy, unknown primary, upper aerodigestive tract, cancer, radiotherapy, squamous cell carcinoma, variants. The diagnostic workup includes a head and neck scanner or MRI, ((18)F)-FDG PET CT, a panendoscopy and tonsillectomy. Squamous cell carcinoma represents over two thirds of cases. The number of metastatic cervical nodes, nodal level, and histological variant (associated with HPV/EBV status) may determine the primary site origin and might be weighted for the determination of radiation target volumes on a multidisciplinary basis. A selective customized approach is relevant to decrease radiation toxicity only if neck and mucosal control is not impaired. Although no recommendation can yet be made in the absence of sufficient level of evidence, the relevance of systematic pan-mucosal irradiation appears questionable in a number of clinical situations. Accordingly, a customized selective redefinition of target volumes may be discussed and be prospectively evaluated in relation to the therapeutic index obtained.

HPV and head and neck cancer.

Head and neck cancer is frequent worldwide and oropharyngeal locations are presently sharply on the increase, in relation with an increasing incidence of oropharyngeal infection by oncogenic type-16 human papillomavirus (HPV). The clinical and biologic profile of these patients is distinct from that of other oropharyngeal carcinoma patients, with earlier onset, cystic cervical nodes and basaloid carcinoma histopathology. Detection of intratumoral viral DNA is essential to confirm the role of HPV, and E6/E7 mRNA expression is the most relevant indicator for stratification. Several methods can reveal intratumoral oncogenic HPV DNA, but PCR with hybridization is the most sensitive and most widely used. According to several reports, prognosis in terms of survival and locoregional control is better in HPV-positive oropharyngeal carcinoma than in oropharyngeal carcinoma associated with smoking and alcohol consumption. The future lies in vaccination, but further studies will determine whether the rate of oropharyngeal carcinoma falls in women vaccinated against cervical cancer.

Microbiology of facial cellulitis related to dental infection.

OBJECTIVE: The study objective was to identify bacteria responsible for facial cellulitis of dental origin. DESIGN: Adult patients, admitted for facial cellulitis of dental origin were included. The pus sample was taken by swabbing during the surgical incision and drainage performed under general anesthesia. The bacteriological diagnosis was performed by microscopic examination and bacterial culture in aerobic and anaerobic atmosphere. RESULTS: Two hundred and seven bacterial species were isolated from 100 samplings, that is to say 2.07 bacterial species per sample. 19% of the samples contained only aerobic germs, 36% only anaerobic ones, and 45% contained mixed aerobic and anaerobic flora. Streptococcus (65.38%) and Capnocytophaga (11.54%) were the most frequently isolated aerobic bacteria. The anaerobic bacteria accounted for 62.32% of isolates and the most frequently isolated were Prevotella (55%) and Fusobacterium (16.28%). Bacterial species were not significantly different according to the age (P-value=0.06) and sex (P-value=0.584). There was a significant statistical association between aerobic or anaerobic bacteria and clinical symptoms such as cheek edema (P-value=0.03) and pus at tooth root (P-value=0.02). Patients previously treated by antibiotic therapy presented significantly more infections due to the same respiratory germ type (P-value=0.009). CONCLUSIONS: Even though the bacterial flora responsible for facial cellulitis of dental origin is polymorphic, anaerobic bacteria were predominant.

Altered quality of life in Rendu-Osler-Weber disease related to recurrent epistaxis.

OBJECTIVES: Development and validation of an epistaxis-specific quality-of-life questionnaire (EQQoL) to evaluate the impact on quality of life of epistaxis, during hereditary hemorrhagic telangiectasia (HHT). STUDY DESIGN: Prospective clinical study using QoL instruments administered twice in HHT patients. PATIENTS AND METHODS: In total, 109 patients who had epistaxis and a clinical diagnosis of HHT according to Curacao criteria were included. Invoice of the questionnaire in 2004 and 2006 included SF-36, Jenkins` sleep scale and the new epistaxis-specific13-item EQQoL. RESULTS: EQQoL uptake rate was 98%, mean score 58/100 +- 27, and Cronbach alpha 0.96. EQQoL was sensitive to change with a strong correlation with the course of epistaxis. Factorial analysis showed that EQQoL was clearly distinct from SF-36 and Jenkins sleep scales. In stepwise multivariate ordinal logistic regression, frequency and duration of epistaxis were both associated with lower EQQoL. Conversely, visceral involvement and comorbidity had independent impact on SF-36 scores, but not on EQQoL. CONCLUSIONS: This new epistaxis-specific EQQoL questionnaire provides complementary information on the impact of HHT on patients quality of life relative to the SF-36 generic questionnaire. After international validation, the EQQoL might prove a useful tool for treatment evaluation.

[Role of imaging in the pre-treatment assessment and post-treatment follow-up of sinonasal malignancies]. / Place de l'imagerie dans le bilan préthérapeutique et la surveillance post-thérapeutique des tumeurs malignes du massif facial.

Malignant sinonasal tumors are the most frequent facial malignancies in adults. Assessment of these tumors requires a multidisciplinary approach and imaging plays a major role to define the precise tumor location, volume and extension and to plan post-treatment follow-up. MRI provides superior differentiation between tumor and surrounding tissues and depiction of intracranial or perineural extension. CT is a useful complement to demonstrate bone erosion or extension into the skull base.

Nasal polyposis: is there an inheritance pattern? A single family study.

BACKGROUND: Nasal Polyposis (NP) is defined as a chronic inflammatory disease of sinonasal mucosa leading to diffuse formation of benign polyps. Although family histories are frequently suggested in medical literature, no specific study focused on this point has been reported. The purpose of this study is to determine whether a hereditary factor could be implied for NP in a family where several members were affected. We included 99 members of this family. METHODS: All patients were assessed for conditions known to be associated with the development or presence of NP. Concerning NP, patients were screened with a validated questionnaire and selected patients had a medical examination by an Ear, Nose and Throat practitioner. RESULTS: Thirteen patients had a personal history of NP without asthma, aspirin intolerance, Churg Strauss syndrome, cystic fibrosis, Young's syndrome, bare lymphocyte syndrome, or primary ciliary dyskinesia. Within this family, 19.7% of those older than 17 years were affected by NP, as compared with the national French prevalence of 2.1%. CONCLUSIONS: Regarding the pedigree, we discuss different modes of inheritance. The presence of consanguineous unions in this family suggests the possibility of a common ancestor and thus a recessive autosomal mode of inheritance.

[Peak Nasal Inspiratory Flow: learning curve for the measurement method and reproducibility]. / Peak Nasal Inspiratory Flow: apprentissage de la méthode de mesure et reproductibilité.

OBJECTIVES: A prospective study on the learning curve and reproducibility of PNIF measurement with 18 different operators. MATERIAL AND METHODS: Five hundred twenty-eight patients in two groups were prospectively enrolled in this study from September 2003 to April 2004. The learning curve of the technique was monitored after five patients had been measured. Reproducibility was evaluated with all patients after two consecutive measurements. RESULTS: The technique was acquired by all operators after the fifth patient. The mean PNIF measurements in controls and patients were 86.02+/-36.96 l/min and 89.59+/-41.97 l/min, respectively. Reproducibility (PNIF2-PNIF1=5.51+/-24.93 l/min) was obtained for all operators, whatever the number of measurements taken. CONCLUSIONS: The study confirms the good reproducibility and the easy training in PNIF measurement.
