Experience with the Nucleus multichannel cochlear implant.

We have seen using the Nucleus multichannel cochlear implant since 1984, with more than 200 patients operated. Out of 152 adults, ten have ailed, either because of explants, or because of other causes especially psychological causes. Out of 53 children, only one child seldom wears his device. For the post-lingual adults, the vocal training is very short, during the three weeks hospitalisation necessary to place and to check the implant. The children need a much longer training period, which takes place in a special and pluridisciplinary cochlear implant center.
