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.
Ot ospongiosis is a primary osteodystrophy of the otic capsule that affects genetically predisposed individuals and leads to a progressive hearing loss.
Aim:To evaluate the applicability of audiometric evaluation during drug treatment for otospongiosis.
Materials and Methods:A prospective, randomized, controlled, double-blind study involving 26 patients with clinical, audiometric and CT scan image of otosclerosis. Patients eligible for the study were divided into three groups (A, B and C) and received treatment with alendronate sodium (B), sodium fluoride (C) and placebo (A) for 6 months. After this period they were submitted to new tests.Results: There were not statistically significant differences between air and bone conduction (gap). We also found no differences in the speech recognition threshold (SRT) and speech discrimination (IRF) between before and after treatment.
Conclusion:After six months of drug treatment the audiometric evaluation kept the same hearing thresholds, suggesting stabilization of the otospongiotic lesions. Braz J Otorhinolaryngol. 2012;78(2):73-9.

MRI shows higher sensitivity than clinical or audiometric assessment for detecting reduction in activity of otospongiosis. The objective MRI evaluation based on software analysis was the most accurate method of monitoring clinical treatment response in otospongiosis.
OBJETIVO: Identificar os principais achados tomográficos da otosclerose fenestral e avaliar a utilidade da tomografia computadorizada de alta resolução (TCAR), como método diagnóstico dessa osteodistrofia. FORMA DE ESTUDO: Estudo prospectivo multicêntrico com tomografia computadorizada (TC) de ossos temporais. MATERIAL E MÉTODO: 54 pacientes com diagnóstico clínico e cirúrgico de otosclerose. Foi realizada uma análise tomográfica, em que foi avaliada a sensibilidade da TC no diagnóstico radiológico da otosclerose fenestral, sendo verificados os principais sítios de lesões dessa doença, como também a sua bilateralidade e simetria. Foram incluídos neste estudo 22 pacientes submetidos à TC de ossos temporais para investigação de outras afecções otológicas, que constituíram o grupo controle. RESULTADOS: A TC foi positiva em 87% dos pacientes (77% das orelhas). Os achados tomográficos foram bilaterais na maioria dos casos (78,7%), e o foco fenestral mais prevalente foi o foco anterior à janela oval (FAJO). CONCLUSÕES: A TC apresentou um alto índice de positividade e o FAJO foi o foco mais prevalente nessa população, podendo ser considerado um achado tomográfico altamente sugestivo de otosclerose.
