The effect of interdevice interval on speech perception performance among bilateral, pediatric cochlear implant recipients

Abstract

Objectives/Hypothesis: To determine if prolongation of the interdevice interval in children receiving bilateral cochlear implants adversely affects speech perception outcomes. Study Design: Retrospective chart review. Methods: Retrospective review of our pediatric cochlear implant database was performed. Children who had undergone revision surgery or had less than 12 months listening experience with either the first or second implant were excluded. The interdevice interval, best Phonetically Balanced Kindergarten word lists (PBK) score from each ear, and demographic data about each patient were collected. A ratio of PBK was generated (PBK second side/PBK first side) to minimize potential con..
