Abstract

EOAEs are well correlated with changes of hearing sensitivity during the clinical course of brain stem lesions, as shown in this case study. They may serve as sensitive indicators to evaluate the possible effects of a brain stem lesion on cochlear function and monitor the attempted preservation of hearing during CPA or brain stem surgeries. It is thereby suggested that EOAEs should be included in an audiologic test battery in a differential diagnosis of retrocochlear lesions.

摘要

如本病例研究所示，耳声发射与脑干病变临床过程中听力敏感度的变化密切相关。它们可作为敏感指标，用于评估脑干病变对耳蜗功能的可能影响，并在小脑脑桥角（CPA）手术或脑干手术期间监测听力保留情况。因此，建议在蜗后病变的鉴别诊断中，耳声发射应纳入听力测试组合中。
