Abstract

The time course of speech development in children after cochlear implantation may extend over many years, thus making long-term studies necessary to evaluate any outcome. We report our long-term results after cochlear implantation in children and adolescents. Mean follow-up was 28 months, ranging from 1 to 5 years. After at least 1 year of experience all children were found to benefit from their cochlear implants. The majority of children scored above chance in speech identifcation tasks requiring closed set word and sentence understanding). At the 4-year interval, all children tested including prelingually deaf children had developed open set sentence understanding. The most relevant factor accounting for differences in the results was the duration of implant use in all groups. Even beyond 3 years the results continued to improve. Peri- or postlinguallly deafened children tended to have favorable results. For prelingually deaf children, duration of deafness and age at implantation were correlated negatively with the results.
