[Cochlear implantation, new prosthetic alternative in the management of the profoundly deaf child]

Cochlear implants are new medical devices. In contrast to acoustic hearing aids which work by amplification, cochlear implants directly stimulate the hearing neurons via electrode implanted in the cochlear tympanic ramp. They are indicated in case of profound hearing deficiency or in cases of bilateral cophosis, congenital or acquired. Implanted early, they allow deaf children to improve their speech comprehension and their verbal expression considerably, thereby favouring social integration. A concurrent system of support including the use of visual-manual means of communication nevertheless remains vital for the first years. The frequency and duration of such support varies according to the individual.
