Abstract

This study examined the effects of age at implantation on the development of communication abilities in children with early implantation. The 73 participants were prelingually deafened, received a cochlear implant before 5 years of age, and used current cochlear implant technology. The children were administered a battery of speech and language outcome measures before implantation and again at successive 6-month postimplant intervals. A mixed model analysis was used to examine the rate of growth in word recognition and language skills as a function of age at time of implantation. The results revealed significant improvements in communication skills over time. Spoken word recognition improved at a faster rate in the oral children with early implantation. However, the children who underwent implantation before 3 years of age had significantly faster rates of language development than did the children with later implantation. The oral children demonstrated more rapid gains in communication abilities than did the children who used total communication.
