摘要: 目的:评估人工耳蜗再次植入术的临床特点,总结人工耳蜗再次植入手术的临床经验。方法:回顾性研究分析2002-2012年间进行的25例人工耳蜗再次植入术患者的资料。主要分析再次植入手术的原因、术中的发现、术中电极植入的数量及再次植入术前后的听力及言语的表现。结果:本次再次植入术的原因中,8例植入体物理故障,8例为电极位置不佳,4例首次植入术后效果不佳,3例皮瓣感染导致植入体暴露,1例颞骨病变,1例术后面神经刺激征。25例患者均在我科成功进行人工耳蜗再植入术,术后患者原并发症均治愈,听觉行为分级标准和言语可懂度分级标准及图文识别软件测试言语识别率显著提高,无严重并发症发生。结论:人工耳蜗再植入者原因具有多样性,需根据不同的原因进行个性化的分析和处理。人工耳蜗再次植入术可以取得较好的临床及听力效果,而且是一种安全和有效的手术方式。Abstract: Objective:The aim of this study was to evaluate the clinical features of cochlear reimplantation. To review our experience of cochlear reimplant surgery.Method:Retrospective analysis of all 25 cochlear reimplant surgeries between 2002 and 2012. Causes of revision operations, number of electrode channels inserted, surgical findings and postoperative speech performances were analyzed.Result:Causes of reimplantation were eight hard failures; eight poor implanted electrodes position, four poor outcome, three skin flap infection lead to implant device exposure, one postoperative symptoms of facial nerve stimulation, one postoperative temporal bone lesions. All cochlear reimplantations were successfully performed in our hospital, audiologic performances were stable or improved following reimplantation in most of cases.Conclusion:Cochlear implant surgeons should have a good knowledge of how to diagnose cochlear implant failures and how to deal with medical complications related to cochlear implantation. Medical and audiologic outcomes are generally excellent. Cochlear reimplantation appears to be a safe and effective.
