Vestibular Function Monitoring in a Pediatric Cochlear Implant Program

Abstract

Purpose: The purpose of this project was to retrospectively evaluate a vestibular screening protocol and results in children with cochlear implants (CIs) to provide information for other clinics considering implementing similar programs. Method: A retrospective analysis of chart data was completed using descriptive statistics and a repeated measures multivariate analysis of variance design in context with the current state of literature on vestibular monitoring in the pediatric CI population. Results: Pre-CI testing was focused on cervical vestibular evoked myogenic potentials (cVEMPs), which is an efficient and obtainable measure in this population. Postimplantation vestibular testing proved challenging with a high no-show/cancellation rate. For patients evaluated both pre- and postimplantation, there was no significant difference across patients noted; however, individual differences were noted. Conclusions: Vestibular monitoring of pediatric CI patients is important for the overall health and development of this population. An overall assessment of the program and options for continuation of the program considering this analysis are also provided. cVEMP testing is a good option for vestibular monitoring in pediatric CI patients; however, a multifaceted approach is most likely needed to address the many challenges that exist.
