Effects of Cochlear Implantation on Vestibular Pathway: Follow up Study in Cochlear Implant Children

Different consequences on vestibular function may occur from post-operative electrical current provided by the implanted electrodes. Abdelghaffar and Elshazly [4] reported infrequent vertiginous sensations or imbalance every time the device was activated. On the contrary, Cushing et al. Most of the studies have focused primarily on the adult population. Moreover, pediatric CI candidates may already have significant vestibular impairment before implantation as a result of underlying inner ear pathology. Accordingly, this study was designed to investigate the effect of CI on vestibular pathway by measuring Vestibular evoked myogenic Potentials (VEMPs) in CI children before and after surgery. In addition to study the possible effects of electrical stimulation from CI on vestibular pathway.
