The feasibility of using evoked oto-acoustic emission (EOAE) measurement for intra-operative monitoring of cochlear function was assessed during removal of an acoustic neuroma in a 53-year-old woman with normal hearing on the operated side prior to surgery. The high level of noise in the operating theatre was the only material problem encountered and this was not sufficient to prevent recording of identifiable waveforms. During manipulation of the brainstem, damage to the cochlea was indicated by an increase in EOAE latency and its eventual disappearance. A total hearing loss in the operated ear was revealed after surgery. Monitoring cochlear function with EOAEs is probably best considered at present as an adjunct to auditory brainstem response monitoring of the composite cochlea and eighth nerve, thus providing differential information.
在一名53岁手术侧术前听力正常的女性切除听神经瘤的手术过程中，评估了使用诱发耳声发射（EOAE）测量进行术中耳蜗功能监测的可行性。手术室中的高噪音是遇到的唯一实质性问题，但这并不足以妨碍记录可识别的波形。在脑干操作过程中，EOAE潜伏期延长并最终消失表明耳蜗受到损伤。术后发现患侧耳朵完全失聪。目前，使用EOAEs监测耳蜗功能可能最好被视为对复合耳蜗和第八神经进行听觉脑干反应监测的辅助手段，从而提供鉴别信息。
