Vestibular syndrome after cochlear implantation

Abstract

Vestibular syndrome after cochlear implantation is described in the literature. Its causes are variate but not always amenable to etiologic approach. We describe a patient which developed cochlear electrode extrusion with persistent vestibular symptoms after a successfull insertion. Material and method. Photos from surgery and CT imaging were used to show this postoperative complication. Results. Revision surgery was necessary to reinsert and properly imobilise the electrode to the osseous walls of the mastoidectomy cavity. Symptoms disappeared completely after this procedure. Conclusions. Persistent vestibular symptoms after cochlear surgery require special and continuous monitoring. Revision surgery is indicated wherever imaging investigations suggest possible and correctable causes.
