Pediatric Cochlear Implant Failures and Vestibular Anomalies
Beck et al (2015) reported vestibular and balance disorders are highly associated with SNHL in children, however, most professionals don’t screen for vestibular dysfunction in (these same) children. The authors estimated the prevalence of vestibular and balance disorders in children may be as high as 15 percent of all children, and up to 70 percent children with SNHL.
Wolter et al (2015) evaluated 35 children who had experienced cochlear implant (CI) failures and compared them to 165 children with CIs who did not experience failures. The authors report 59 percent of the children with CI failure had an etiology of hearing loss often associated with vestibular disorders, whereas in the “control” group (165 children without CI failures) only 33 percent of the children had an etiology associated with vestibular disorders. Of note, Wolter et al report that “…bilateral horizontal canal dysfunction, increased the odds of CI failure and need for subsequent re-implantation by 8-fold….” The authors note their study is the first to identify the increase in CI failures in the presence of vestibular and balance impairment in the pediatric population.
