Cochlear implantation is an increasingly used technique for auditory rehabilitation of pediatric and adult population. Safe implantation is achieved in most cases; however, intraoperative complications and misplacement of the electrode are observed in some. The aim of this presentation was to review the characteristics of patients with extra-cochlear electrode insertion, postoperative diagnostic methods, and considerations in revision surgery.
In total, 423 cases of cochlear implantation performed in our clinic between 2012 and 2018 were retrospectively analyzed and those of extra-cochlear implantation were evaluated.
Extra-cochlear insertion was found in 3 patients. The electrode was placed into the internal acoustic canal in the first case, superior semicircular canal in the second case, and internal carotid artery canal in the third case. Cochlear insertion was achieved in all cases with re-implantation, and no complication was observed.
This case series highlights that rare, but potentially serious, consequences of misplacement of the electrode in cochlear implantation can be successfully avoided and treated via a multidisciplinary approach.
人工耳蜗植入是一种在儿童和成人听觉康复中越来越常用的技术。大多数情况下能实现安全植入；然而，在某些病例中会观察到术中并发症和电极误植情况。本报告的目的是回顾耳蜗外电极植入患者的特征、术后诊断方法以及翻修手术中的注意事项。
回顾性分析了2012年至2018年在我院进行的423例人工耳蜗植入病例，并对耳蜗外植入病例进行了评估。
发现3例为耳蜗外植入。第一例电极置于内耳道，第二例置于上半规管，第三例置于颈内动脉管。所有病例再次植入后均成功实现耳蜗植入，且未观察到并发症。
本病例系列强调，通过多学科方法可以成功避免并治疗人工耳蜗植入中电极误植这种罕见但可能严重的后果。
