[Neurinoma of the VIIIth cranial nerve with negative electrophysiological findings]. / Neurinome du VIII à bilan électrophysiologique négatif.

Electrophysiological features in acoustic neurinoma are reviewed. A case of an acoustic neurinoma with a normal BERA is reported. The authors conclude that no isolated electrophysiological sign is able to disclose a retrocochlear hearing loss. They insist on the necessity to interpret an unilateral hearing loss on basis of an integration of a complete clinical, paraclinical and electrophysiological testing.

[Current data on barotraumatic ear disease with isolated vestibular expression during apnea diving]. / Données actuelles sur l'otopathie dysbarique à expression vestibulaire isolée au cours de la plongée en apnée.

The authors have taken an interest in isolated vertiginous symptoms observed from free diving patients. In order to achieve a current bibliographic synthesis, they resume, on basis of 6 cases, the basic principles of the physics theories and the etiopathogenic mechanisms. They try so to help in the understanding of the vestibular clinical signs observed in this successful sport.

Surgical experience with juvenile nasopharyngeal angiofibroma.

A retrospective analysis was made of 24 cases of nasopharyngeal angiofibroma treated by the ENT Department of the Hospital de Clínicas de Porto Alegre between 1975 and 1989. All the patients were male with an average age of 16. All were treated by surgery alone, with an average peri-operative blood loss of 1,784 ml; pre-operative embolization made no significant difference to the blood loss. No other operative complications were encountered. Five patients (21%) had a recurrence, one of which was intracranial and required further surgery to effect a cure. The average length of follow-up was 19 months. We believe that surgical excision must be the treatment of choice for nasopharyngeal angiofibroma.

[Atypical complication of surgery for otospongiosis: the formation of cholesteatoma]. / Complication atypique de la chirurgie de l'otospongiose: la formation de cholestéatome.

Presenting a clinical case, the authors reveal the possible cholesteatoma complications arising from otospongious surgery. He notice that there are very few literature about similar cases. Underlining the rarity of this complication, the authors will put forward concisely the principal etiological mechanisms occurring in this kind of pathology. Since the reoperation must often be carried out on fragile inner ears, the authors stress on the necessity to respect the elementary rules of prevention in order to avoid the formation of precholesteatoma states.

[A curiosity in ORL pathology: myiasis of the otorhinolaryngologic cavities]. / Une curiosité de la pathologie O.R.L.: les myiases des cavités oto-rhino-laryngologiques.

The authors report a case of auricular myiasis with a review of literature. Diagnostic, therapeutic and prophylactic means established facing this parasitical disease are analysed.
