title: "Seeing" cochlear implant misplacement without imaging test.
abstract: Electrode array misplacement is an infrequent complication in cochlear implant surgery. A case report of electrode array insertion into the posterior semicircular canal, and its effects on the vestibular function is described. Video head impulse test (vHIT) has become an exceptional diagnostic tool to study vestibular function. We present our experience using the vHIT to detect a misplaced electrode array after cochlear implant surgery.
