The aim of this study was to evaluate the clinical features of cochlear reimplantation. To review our experience of cochlear reimplant surgery.
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.
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.
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.
本研究旨在评估人工耳蜗再次植入的临床特征，回顾我们在人工耳蜗再次植入手术方面的经验。
对2002年至2012年间的25例人工耳蜗再次植入手术进行回顾性分析。分析翻修手术的原因、插入电极通道的数量、手术发现及术后言语表现。
再次植入的原因包括8例硬件故障；8例植入电极位置不佳；4例效果不佳；3例皮瓣感染导致植入装置外露；1例术后出现面神经刺激症状；1例术后出现颞骨病变。我院所有人工耳蜗再次植入手术均成功完成，大多数病例再次植入后听力表现稳定或改善。
人工耳蜗植入外科医生应熟知如何诊断人工耳蜗故障以及如何处理与人工耳蜗植入相关的医疗并发症。医疗和听力结果总体良好。人工耳蜗再次植入似乎是安全有效的。
