Cochlear implant electrode array misplacement is a rare but serious complication that may result in failure of hearing rehabilitation, non-auditory percepts, vestibular disturbance, or damage to adjacent neurovascular structures. We present a case of an elderly patient who suffered electrode array misplacement into the posterior semicircular canal, resulting in vestibular symptoms and severe downstream sequelae. The risk of misplacement may be higher in patients with a history of chronic otitis media or prior otologic surgery, and with the use of pre-curved electrode arrays. Electrophysiological testing and intraoperative imaging may allow for early detection and intervention in these cases. Laryngoscope, 133:175-177, 2023.
人工耳蜗电极阵列错位是一种罕见但严重的并发症，可能导致听力康复失败、非听觉感知、前庭障碍或邻近的神经血管结构损伤。我们报告了一例老年患者，其电极阵列错位至后半规管，导致前庭症状和严重的下游后遗症。有慢性中耳炎或既往耳科手术史的患者，以及使用预弯电极阵列的患者，发生错位的风险可能更高。电生理测试和术中成像可能允许在这些情况下早期检测和干预。《喉镜》，133:175-177,2023。
