Cochlear implantees who received revision surgeries after implantation INTERVENTIONS:: Any surgical intervention, performed due to device failure or the major complications of cochlear implantation.
Medical records of the patients who received cochlear implants (CIs) between July 2002 and March 2018 were reviewed retrospectively regarding postoperative complications. Demographic data, device survival rates, and causes of revisions were recorded.
Totally, 924 implantations were performed in 802 patients. Eighty one (8.7%) of them underwent 102 revision surgeries. The most common causes of revision surgeries were device failures and flap related problems which were seen in 28 and 18 patients, respectively.Overall CI survival rate was 91.9% in a 10 years period, which remained almost stable after 10 years. Although age was not found to be related with device failure (p = 0.693), device loss rates were significantly higher in adult implantees than children (p = 0.006).
Device failure seems the most common cause of revision. The revision surgeries are usually safe and help to resolve the problem although flap problems are the most difficult to treat and may necessitate multiple revision surgeries. The device failure rate may reach to a plateau after 6 years. Overall CI survival rate exceeds 90% in 10 years period, and then remains stable.
评估人工耳蜗植入后的翻修手术的病因、人口统计学、发生率和结果，以及设备的存活率。

植入人工耳蜗后接受翻修手术的患者。
任何由于设备故障或人工耳蜗植入的主要并发症而进行的手术干预。
回顾性分析 2002 年 7 月至 2018 年 3 月期间接受人工耳蜗植入的患者的病历，记录术后并发症。记录人口统计学数据、设备存活率和翻修原因。
总共对 802 名患者中的 924 名患者进行了植入手术，其中 81 名（8.7%）患者进行了 102 次翻修手术。翻修手术最常见的原因是设备故障和瓣相关问题，分别见于 28 例和 18 例患者。在 10 年期间，总体人工耳蜗的存活率为 91.9%，10 年后基本保持稳定。尽管年龄与设备故障无关（p=0.693），但成年植入者的设备丢失率明显高于儿童（p=0.006）。
设备故障似乎是翻修的最常见原因。尽管瓣问题是最难治疗的，可能需要多次翻修手术，但翻修手术通常是安全的，可以帮助解决问题。设备故障发生率在 6 年后可能达到平台期。在 10 年期间，总体人工耳蜗的存活率超过 90%，之后保持稳定。
