A Rare Case of Cochlear Implant Electrode Array Misplacement Into the Posterior Semicircular Canal

alexandrossfakianakis shared this article with you from Inoreader A Rare Case of Cochlear Implant Electrode Array Misplacement Into the Posterior Semicircular Canal via The Laryngoscope In this report, we present a case of an elderly patient who suffered cochlear implant 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. 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.
