BACKGROUND
Cochlear implant explantation and reimplantation (ERI) are rarely required, but the widespread use of implants has made it a procedure that every otologic surgical center must address. Although generally described as safe, ERI presents specific surgical challenges, particularly concerning the replacement of the array.
METHODS
The transmeatal section of the array as the initial step of cochlear implant ERI is proposed and described.
RESULTS
A brief case series did not report any specific complications.
CONCLUSION
The transmeatal section of the array allows for the early and safe removal of the cable portion within the mastoid, enabling the surgeon to address scar tissue and new bone formation without the hindrance of the cable and preventing the premature removal of the array in the cochlea.
背景
人工耳蜗取出及重新植入术（ERI）很少需要进行，但随着人工耳蜗的广泛使用，这已成为每个耳科手术中心都必须应对的一项操作。尽管通常认为该手术是安全的，但ERI存在特定的手术挑战，尤其是在电极阵列的更换方面。
方法
提出并描述了将电极阵列经耳道切开作为人工耳蜗ERI的第一步。
结果
一个简短的病例系列未报告任何特定并发症。
结论
电极阵列经耳道切开可早期安全地移除乳突内的电缆部分，使外科医生能够处理瘢痕组织和新骨形成，而不受电缆的阻碍，并防止过早取出耳蜗内的电极阵列。
