To study the prevalence of revision cochlear implant study in a tertiary care referral center. To assess the various indications and surgical outcomes of revision cochlear implant surgery. A retrospective chart review of revision cochlear implant surgery done from June 1997 to December 2019. All the surgeries that were done in children of 12 years and below were included. The revision surgeries were either with or without explantation and reimplantation. The causes included were device failures, electrode extrusion/malposition, magnet migration, persistent foreign body reaction, facial twitching, wound infection, and cholesteatoma. A total of 1636 pediatric cochlear implantation surgery were performed during the study period of 22 years. There were 94 (5.7%) revision surgeries done for various indications during this period. Out of them, 67 patients (71.3%) had device failure thus being the commonest indication for revision surgery, followed by infection in 12.8% of the total patients. Among the total revision, 81 (86.2%) patients had explantation and reimplantation of the new device. Indications of revision cochlear implant surgery are manifold that can be either device-related or patient-related. Revision surgery needs a highly skilled and experienced team of surgeons, audiologists, and habilitationists for achieving optimal results.
研究在三级医疗转诊中心进行修正人工耳蜗植入研究的流行率。评估修正人工耳蜗植入手术的各种适应证和手术结果。
对 1997 年 6 月至 2019 年 12 月期间进行的修正人工耳蜗植入手术进行回顾性图表审查。所有在 12 岁及以下儿童中进行的手术均包括在内。修正手术包括或不包括取出和重新植入。适应证包括设备故障、电极脱出/错位、磁铁迁移、持续性异物反应、面部抽搐、伤口感染和胆脂瘤。
在 22 年的研究期间，共进行了 1636 例小儿耳蜗植入手术。在此期间，因各种适应证共进行了 94 例（5.7%）修正手术。其中，67 例患者（71.3%）因设备故障而进行了修正手术，这是修正手术最常见的适应证，其次是感染，占总患者的 12.8%。在总修正中，81 例（86.2%）患者进行了新设备的取出和重新植入。修正人工耳蜗植入手术的适应证多种多样，既有与设备相关的，也有与患者相关的。修正手术需要一支由经验丰富的外科医生、听力学家和康复治疗师组成的高度熟练的团队，以达到最佳效果。
