Étude de divers aspects de la prise en charge des acouphènes pour un sourd unilatéral avec le stimulateur électrique implantable extracochléaire Tinnelec RW<superscript>®</superscript>. (French)

Study of some aspects of the tinnitus treatment for unilateral deaf with an extracochlear electrical stimulation device. In France, there are about 6000 cases of sudden hearing loss, all of them bring with tinnitus. At present, the treatment of chronic tinnitus is based on the natural development or the facilitation of habituation. For the tinnitus, which resist to the habituation, the principle of the treatments consists in facilitating the habituation process. In a sound therapy the use of a sound generator, with a hearing aid if necessary, is proposed in order to facilitate habituation. But, in case of unilateral deafness acoustical habituation is not possible and tinnitus may cause a depression. Electrical stimulation offers a new therapeutic perspective, which overcomes the main problems to habituation. This approach is very promising that''s why it seems essential to study some aspects. The project tries to answer to four questions: How do we have to stimulate electrically for a maximal efficiency? how can we fit the electric stimulation for maximal efficiency? When is it necessary to set up the stimulation? Can we intend to apply this technique to subjects having hearing residues? Recent experimental studies have proposed Tinnelec ® stimulator of the MXM Company as a therapeutic solution for the difficult tinnitus treatment in-patient with unilateral deafness. Many points will be examined through a clinical study and an animal study. [Copyright &y& Elsevier]
