Disturbance of vestibular function attributable to cochlear implantation in children

Abstract

Our study supports the potential negative impact on vestibular function caused by cochlear implantation, especially for children who receive bilateral implantation. Vestibular impairment or dysfunction after cochlear implantation is clinically significant and should be well addressed preoperatively. Vestibular evaluation such as VOR and VEMP testing can be used in screening vestibular function for children who are candidates for CI. Future improvements in design of CI electrodes and surgical technique may minimize the traumatic impact of cochlear implantation on the inner ear structures and functionality.
