The authors have studied a population of 21 pre-lingually deaf children equipped with a cochlear implant for at least 24 months. Their linguistic progression after implantation has been compared with the standard language development in normally hearing children, using a model published by Marie Therese Le Normand in 1996. 3 types of development can be distinguished: Profile 1 (shown by 9 children) in which language development after implantation is rapid and homogeneous: profile 2 (shown by 8 children), in which it is slower and more heterogeneous, with a longer pre-linguistic phase; Profile 3 (shown by 3 children) in which there are diverse problems with development. The authors then searched to establish the influence of the age at implantation and the mode of communication on this development.
