The incidence rate of the cerebrospinal fluid (CSF) gusher in cochlear implant with inner ear abnormality is 30%. Bony defect in the fundus of the internal acoustic meatus is most often responsible for the occurrence of CSF gusher. This feature of the CT scan can be used to predict the occurrence of a CSF gusher.
To predict the occurrence of CSF gusher in cochlear implants with inner ear abnormality.
This was a retrospective analysis of 442 patients with inner ear abnormality who underwent cochlear implantation from February 1998 to July 2011. The patients were reviewed for the findings on temporal high resolution computed tomography (HRCT) scans and the complication of CSF gusher in cochlear implantation.
Among the 422 cases, 134 (30%) suffered from the complication of CSF gusher during the operation. They were all found to have a bony defect in the fundus of the internal acoustic meatus on the CT scans.
内耳异常的人工耳蜗植入术中脑脊液（CSF）漏出的发生率为30%。内耳道底部的骨质缺损最常导致CSF漏出的发生。CT扫描的这一特征可用于预测CSF漏出的发生。
预测内耳异常的人工耳蜗植入术中CSF漏出的发生。
这是一项对1998年2月至2011年7月期间接受人工耳蜗植入的442例内耳异常患者的回顾性分析。回顾了患者颞骨高分辨率计算机断层扫描（HRCT）的结果以及人工耳蜗植入术中CSF漏出的并发症情况。
在422例患者中，134例（30%）在手术期间出现了CSF漏出的并发症。CT扫描显示他们在内耳道底部均有骨质缺损。
