This is a case of successful cochlear implantation in a 50-year-old man who experienced sudden hearing loss and developed ipsilateral severe tinnitus at three years following conservative stage 1 vestibular schwannoma retrosigmoid surgery. After cochlear implantation, tinnitus improved from THI grade 4 to 2. Localisation skills improved. Hearing in noise (S/N + 7 dB) with target signal from the operated side improved from 38 to 100% of correct answers. A significant improvement of spatial and speech items of the "speech, spatial and qualities of sounds" questionnaire was also measured. In conclusion, cochlear implantation is a feasible and effective solution after conservative vestibular schwannoma surgery should delayed hearing loss occur.
这是一例50岁男性成功植入人工耳蜗的病例。该患者在接受一期保守性乙状窦后前庭神经鞘瘤手术后三年出现突发听力损失，并伴有同侧严重耳鸣。人工耳蜗植入后，耳鸣从THI 4级改善至2级。定位能力得到改善。手术侧目标信号的噪声中听力（信噪比+7 dB）正确答案从38%提高到100%。“语音、空间和声音质量”问卷中的空间和语音项目也有显著改善。总之，如果保守性前庭神经鞘瘤手术后出现延迟性听力损失，人工耳蜗植入是一种可行且有效的解决方案。
