蜗窗膜入路人工耳蜗植入术

Cochlear implantation with round window insertion

目的探讨双侧重度感音神经性聋蜗窗膜入路人工耳蜗植入手术方法。方法 2009年1月~2012年12月安徽省立医院耳鼻咽喉头颈外科共对509例患者行人工耳蜗植入。年龄为8个月~78岁,平均年龄4.3岁。男性328例,女性181例。12岁及以下儿童为365例,12岁以上为144例。结果509例患者中有460例患者成功进行蜗窗膜入路电极植入,比例为90.3%。12岁及以下儿童中365例患者中有323例成功植入,比例为88.4%,12岁以上144例患者中137例成功植入,比例为95.1%。术后随访6个月~3年,未出现1例颅内感染,开机后人工耳蜗工作正常。结论重度感音神经性聋患者蜗窗入路人工耳蜗植入是一安全有效的手术方式,但仍具有一定的挑战性,尤其在儿童中。

OBJECTIVE To discuss the surgical techniques of cochlear implantation with round window insertion in patients with bilateral profound sensorineural hearin loss. METHODS Retrospective study of the data collected from patients receiving cochlear implantation. CI was performed in 509 patients in Anhui Provincal Hospital from January 2009 to December 2012. The mean age of the patients was 4.3years（range 8months–78years）, including 328 males and 181 females. RESULTS Of 509 patients underwent CIs, 460 patients were performed with round window insertion, the rate was 90.3%. All electrodes were implanted successfully, in which the CI went normally and electrode array were protected well. All implant devices had worked normally and all patients had performed well during an average follow-up period of 0.5-3 years. CONCLUSIONCochlear implantation could be performed in patients with round window insertion, and it is a safe and effective way, but is challenging,especially in young childern.
