Sulcus vocalis is described as a groove at the free edge of the vocal fold. Different types have been described: sulcus type I is superficial and may be considered as moreless physiologic. Sulcus type IIa corresponds to a kind of vergeture along the margin of the vocal fold. Its deepness is variable but sulcus vergeture may involve deeper layers of the lamina propria. Sulcus type IIb or pounch may be considered as an open cyst. Sulcus lead to a complex glottic dysfunction with, in the same time, a glottal leakage responsible for the breathy component of the dysphonia and a stiffness of the free edge responsible for the roughness. Diagnosis may be difficult even with the help of stroboscopy and finally is sometimes done only under general anesthesia. Etiology remains controversial and the authors present arguments for each theory, acquired or congenital. Treatment options include phonosurgery and speech therapy but phonosurgery gives results often disappointing and surgical treatment must be indicated prudently and patient must be intensively informed on what he or she can expect from the treatment that is mainly an increase of the loudness of the voice.

Procedures putting healthcare workers in close contact with the airway are particularly at risk of contamination by the SARS-Cov-2 virus, especially when exposed to sputum, coughing, or a tracheostomy. In the current pandemic phase, all patients should be considered as potentially infected. Thus, the level of precaution recommended for the caregivers depends more on the type of procedure than on the patient's proved or suspected COVID-19 status. Procedures that are particularly at high risk of contamination are clinical and flexible endoscopic pharyngolaryngological evaluation, and probably also video fluoroscopic swallowing exams. Voice rehabilitation should not be considered urgent at this time. Therefore, recommendations presented here mainly concern the management of swallowing disorders, which can sometimes be dangerous for the patient, and recent dysphonia. In cases where they are considered possible and useful, teleconsultations should be preferred to face-to-face assessments or rehabilitation sessions. The latter must be maintained only in few selected situations, after team discussions or in accordance with the guidelines provided by health authorities.

International audienceIntroduction The role of fine-needle aspiration cytology (FNAC) in the management of parotid tumours is still the subject of controversy. The purpose of this study was to determine the diagnostic value of FNAC in our institution in order to define its place in the diagnostic strategy.Patients and methods :This retrospective study was based on 249 patients who had undergone preoperative FNAC before being operated in our institution between 2001 and 2008. All examinations were performed and interpreted by the same experienced pathologist.Results, Among the 249 patients included in this study, 187 (75%) had a benign tumour and 62 (25%) had a malignant tumour. No complications of FNAC were observed. Cytological findings were non-contributory in 47 patients (18%). The sensitivity of FNAC for the diagnosis of malignancy was 80% with a specificity of 89.5%. Among the 11 false-negative results, lymphomas and low-grade mucoepidermoid carcinomas were the most common histological types. Among the 16 false-positive results, Warthin's tumours, pleomorphic adenomas and lymphoepithelial lesions were the most common histological types. Accurate histological classification of the tumour was reported in 79.5% of cases (86% for benign tumours and 44% for malignant tumours).Conclusion FNAC is a reliable examination providing important information to the surgeon in the preoperative diagnostic assessment

The present results show that margins considered positive after laser resection do not significantly impact carcinologic course, while still requiring close surveillance. The most generally recommended attitude is control endoscopy with biopsy at 10 weeks.

Vascular malformations of the parotid gland, rare disease, are mainly venous. The terminology is based on clinical data, scalable, histological and hemodynamic as classified by the International Society of Study of Vascular Anomaly (ISSVA). Despite advances in imaging including MRI they remain difficult to diagnose. The treatment of reference is surgical excision.

Lipomas arising from the parotid gland are very rare. We report a 10-year experience in a single institution (La Timone University Hospital of Marseille, France). Among 614 parotidectomies for neoplasms performed from 1998 to 2008, 12 lipomas were identified. A retrospective analysis based on medical records was made. Evaluation, analysis and current management of lipomas of the parotid gland are described. Lipomas accounted for 2% of all parotid neoplasms and 2.6% of benign tumors in our series. The median age of patients was 60 years with a M/F sex ratio of 5-1. The main presentation was a soft asymptomatic, slow-growing, mobile mass although 30% had an indurated mass on palpation. Diagnosis of lipoma, based on the results of imaging, was made preoperatively in all cases. The mean tumor duration prior to excision was 11.5 months. The surgical decision was made regarding increased swelling with functional/esthetic discomfort in 83% of cases. Partial parotidectomy was performed in most cases. Postoperative complications occurred in 16% of cases although no permanent complication was observed. No recurrence was observed in our series. Histologically, 92% of tumors were classic lipomas. Lipomas can be clinically misleading since 30% of patients in our series showed an indurated mass on palpation. Preoperative imaging, especially MRI, is the cornerstone of their management as it allows very accurate lipoma diagnosis. Since in our series, diagnosis of lipoma had been made preoperatively in all cases, the surgical excision could be delayed and finally surgical decision has been made for esthetic and/or functional considerations in more than 80% of cases.
