[Study of a case of cochlear implant with recurrent cutaneous extrusion].

Objective: An observation of a difficult-to-diagnose complication of the cochlear implant: recurring cutaneous extrusion of a cochlear implant is reported.

Patients And Methods: The history of an adult patient with total deafness is reported. She received an implant in her right ear in 1988, which was then explanted because of absence of hearing results.

[Evaluation protocol of cochlear implants in children under 5 years of age].

Special tests are necessary to assess the cochlear implant efficacy on a prelingually deaf child implanted before age 5 y. We propose to quantify comportment, comprehension, auditory perception and expression as percentage of a same age normally hearing child's scores. The particular items are detailed.
