[Bone anchored hearing aid. Results of bilateral applications]

In our experience B.A.H.A. (Bone Anchored Hearing Aid) with its direct bone conduction brings a better hearing rehabilitation for patients with draining ear and further more with major aplasia. 23 patients were tested, 12 have got a bilateral hearing aid, 5 unilateral. They reported a better comfort, a more natural sound and a better discrimination in noise. A bilateral application brought them a stereoacousy with a special directivity, we also note improvement of hearing by different hearing tests.
