[A hearing implant: indications, technic and results].

Abstract The authors report four cases of implantation of a new device via an osseous approach involving implantation of an intra-osseous vibrator and of an external box, transmission being by magnetic induction using an external aerial, i.e. with no transcutaneous portion. The Xomed Audiant is an osseous rehabilitation system designed essentially for use in transmission deafness which cannot be corrected by conventional surgery or cannot be managed by an air conduction device, e.g. agenesis of the ear or sequelae of evacuation cavities in otorrhea. The authors report their experience of four cases of implantation, in terms of indications, selection assessment and evaluation protocol as well as functional results and prostatic adjustment, with a critical review of advantages and disadvantages in comparison with classical methods.
