[Cervical and pharyngeal inflammatory pseudo-tumors, a report of two cases: clinical course and treatment].

The authors report two new cases of inflammatory pseudotumours, sited in the pharynx and neck--sites in which no previous cases have so far been reported in the literature. The aetiology and clinical course of these rare benign tumours remain little understood even today. Their treatment is also not clearly described.

[Oto-neuro-surgical approach and accessibility to the cochlear nuclei. Significance in auditory brain stem implant].

The auditory brainstem implant (ABI) is now used to stimulate the cochlear nucleus to obtain auditory perception in patients with type 2 neurofibromatosis. Only electrical stimulation of the cochlear nucleus complex, in the lateral recess of the fourth ventricle, can achieve auditory rehabilitation of these profound bilateral retrocochlear deafness. With 20 standard translabyrinthine approaches, our personal anatomical study propose to describe surgical landmarks of the cochlear nuclear complex and surgical accessibility of the lateral recess of the fourth ventricle.

[Diagnostic criteria for progressive necrotizing external otitis. Are scintigraphic findings reliable?].

Objectives: Determine the role of 99m technetium scintigraphy for diagnosis in progressive necrotizing external otitis and assess the diagnostic criteria of this disease.

Method: A retrospective study was conducted in 16 patients hospitalized for suspected progressive necrotizing external otitis. Patient characteristics, clinical features, imaging findings and disease course were recorded in order to evaluate the classical criteria of diagnosis.
