[Setting up a "Bonebridge"].

Hearing rehabilitation after bilateral radical mastoidectomy has different options. The Bonebridge is a new type of middle ear implant bone conduction. It leaves the external ear canal opened and offers acoustic and aesthetic advantages that make it a new alternative of choice. We report our first case of Bonebridge implanted on a 17 years old patient. He had bilateral conductive hearing loss secondary to a bilateral radical mastoidectomy with open technique and meatoplasty for a bilateral cholesteatoma. The surgical technique is described. After 8 months of use the hearing gain is stable without cutaneous adverse effect.
