ABSTRACT
A surdez súbita sensorioneural é uma perda auditiva súbita ou rapidamente progressiva. Na maioria dos casos a etiologia não é descoberta. Uma das causas possíveis de surdez súbita é a hemorragia intralabiríntica que, antes do surgimento da ressonância magnética, não era corretamente diagnosticada. O objetivo deste trabalho é relatar um caso de surdez súbita causada por hemorragia intralabiríntica e realizar uma revisão da literatura sobre este assunto.
Sudden sensorineural hearing loss is relatively frequent. In most cases, the etiology is not discovered. One of the possible causes for sudden deafness is inner labyrinth bleeding, which was difficult to diagnose before the advent of magnetic resonance imaging. The purpose of this paper is to report a case of sudden hearing loss caused by a labyrinthine hemorrhage, and to present a review of the literature on this topic.

A ototoxicidade secundária ao uso de medicações é um acontecimento presente na prática médica diária e que deve ser evitada. Para tal, torna-se imprescindível o conhecimento das drogas potencialmente tóxicas à orelha interna, bem como a detecção precoce dos danos por elas provocados. Este artigo tem como objetivo destacar os fármacos de maior impacto no desenvolvimento de ototoxicidade, bem como sugerir medidas para sua prevenção

Thirty five patients of either sex suffering from tuberculosis were administered streptomycin 0.75 g (im daily, upto 14 yr and above 45 yr of age) and 1 g (im daily for age 15-45 yr) with other antitubercular drugs and followed for audiological status. Five patients were dropped as they developed vestibular dysfunction. Varying degree of hearing loss was detected in 4 of 10 patients in group I (below 15 yr), in 2 of 9 patients in group II (15-45 yr) and in 6 of 11 patients in group III (above 45 yr). Cochlear toxicity of streptomycin was not found to be related to does or duration of therapy. Supportive therapy restored hearing in 2 patients of group I and 1 of group II. None of the patients in group III showed recovery. It is recommended that patients on long-term streptomycin therapy should be periodically subjected to audiometric examination to detect any hearing loss.
