Abstract Multichannel cochlear implantation is a clinical technique that was introduced at the University Hospitals of Geneva (HUG) in 1985, by Prof Pierre Montandon. In 1994, I received the medical charges of the Centre Romand d'Implants Cochléaires (CRIC) that consisted of performing all surgical implantations as well as of promoting the paediatric cochlear implantation. This practice is the central focus of this thesis, which is presented in the form of a report on the experience and the lessons learned during the past 25 years within the framework of the CRIC. During this period, more than 200 implantation surgeries were performed on more than 170 patients suffering from various types of deafness. This thesis is based on clinical studies and original data gathered between 1985 and 2009 by the multidisciplinary team of the CRIC. It includes three main parts. The first is a description of the methods and approaches followed by our team. The second part presents the results in terms of the hearing performance of the implanted patients who were classified according to three different clinical situations: post-lingually deafness, pre-lingually deafness with early implantation and some rare cases of pre-lingually deafness with late implantation. This part also includes an examination of the cases which involved complications caused by the implant, in particular those which required a reimplantation. A third and final Chapter describes the development of another type of internal ear implant by addressing the incipient question of vestibular implant. The work described in this Chapter is to my knowledge the first report on human vestibular responses elicited by electrical stimulation.
