Cochlear implants in deaf children

The results to date with the 3M/House cochlear implant in children have been extremely encouraging. Statistically and clinically significant changes show that the implant can provide improvements in auditory detection and discrimination as well as in speech production. As with any intervention, results range from outstanding for some children (open-set speech discrimination and/or intelligible speech) to minimal for others (no stimulation or little improvement in speech). Until long-term studies can be completed, the implant will undoubtedly remain controversial. However, professionals involved in the care of a child who is hearing-impaired should be informed that the field of cochlear implantation is rapidly expanding. A number of different cochlear implants are currently undergoing clinical trials in adults. Besides the 3M/House device, the FDA has recently approved a second device, the Nucleus Multichannel Cochlear Implant, for investigation in children. The treatment of profound deafness is changing in children with the cochlear implant as an option for those not benefiting significantly from hearing aids. However, some important aspects of a deaf child's management have not changed and will not change: the need for early diagnosis and multidisciplinary management. The first five years of life are the language acquisition years. Proper management during these years is critical if the hearing-impaired child's handicap is not to dominate his or her future and limit potential for a successful, happy life.
