To discuss the clinical experience of prediction and management about perilymph gusher in cochlear implantation.
Among 327 cases of cochlear implant, eleven recipients were selected by the high resolution computed tomography (HRCT) findings of cochlear malformations and bony fistula on fundus of the internal auditory canal that caused an abnormal connection between subarachnoid and perilymphatic spaces.
Perilymph gusher was found in all of these 11 recipients during cochlear implantation and was controlled with muscle tissue seal.
The reason of perilymph gushers in cochlear implantation is that abnormal connection between subarachnoid and internal auditory canal. HRCT can be used to assess the possibility of perilymph gusher in surgery. The safe and rapid surgical method of gusher controlling can avoid complication.
探讨人工耳蜗植入术中内淋巴瘘的预测及处理的临床经验。
在327例人工耳蜗植入病例中，根据高分辨率计算机断层扫描（HRCT）发现的耳蜗畸形及内耳道底部骨瘘导致蛛网膜下腔与外淋巴间隙异常相通，选取11例受者。
这11例受者在人工耳蜗植入术中均出现内淋巴瘘，通过肌肉组织封闭得以控制。
人工耳蜗植入术中发生内淋巴瘘的原因是蛛网膜下腔与内耳道之间的异常相通。HRCT可用于评估手术中发生内淋巴瘘的可能性。安全快速的内淋巴瘘控制手术方法可避免并发症。
