Many advances have been made in recent years in the development of hearing and cochlear implants. These use acoustic and electrical stimulation technologies to improve speech intelligibility for the hearing impaired. However, for cochlear prostheses, the results are not very promising and vary from one patient to another. Certain technical and sometimes physiological problems have limited the expected performances of these devices, especially for children and the elderly. These problems include cochlear malformation and ossification of the auditory channels. This led us to reduce the number of electrodes in order to allow quality deep insertion while preserving the low-frequency acoustic bands of the operated patient.
