Abstract

In this article, we present three case studies of young children with profound sensorineural hearing loss who received bilateral cochlear implants. In each of these cases, specialists suspected interference between the ears. The audiologist and speech-language pathologist determined that the children had better auditory function and speech and language production when wearing 1 speech processor as opposed to 2 speech processors. In many pediatric implantation cases, experts verify the device fitting in the bilateral condition because infants and toddlers at the prelanguage level are unable to provide specific input during mapping sessions. The cases we describe herein highlight the need for individual ear verification at early stages of speech and language development. In addition, based on these cases, we propose mapping changes that can be made to optimize binaural listening for speech and language development.
