[Endolymphatic sac tumour as an infrequent cause of Ménière's syndrome].

Endolymphatic sac tumours are uncommon. They have been classified as adenocarcinomas with a low degree of malignancy and no metastases have yet been documented. We report on a female patient with Von Hippel-Lindau disease and Ménière's syndrome suffering from an endolymphatic sac tumour.

[EXIT procedure in the management of severe foetal airway obstruction. the paediatric otolaryngologist's perspective].

The ex-utero intrapartum treatment (EXIT) procedure is a technique designed to allow partial foetal delivery via caesarean section with establishment of a safe foetal airway by either intubation, bronchoscopy, or tracheostomy while foetal oxygenation is maintained through utero-placental circulation. The most common indication for the EXIT procedure is the presence of foetal airway obstruction, which is usually caused by a prenatal diagnosed neck mass. We report three cases of head and neck tumours with airway obstruction treated by means of EXIT and with different solutions in the management of the airway.

[Morphometric study of the mastoid segment of the facial nerve].

Objective: Our study emphasizes the relationship between the temporal bone structures and the mastoid portion of the facial nerve.

Material And Methods: Thirty-two temporal bones taken from adult cadavers of both sexes subjected to tympanoplastic procedure were used to make reference measures of the mastoid portion of the facial nerve. Appropriate instruments were used for measurement and statistic analysis was subsequently performed.
