DACS A new implantable Hearing system for Moderate to Severe Mixed Hearing Loss

The adequate treatment of the patients with moderate to severe mixed hearing loss (MHL) is not sufficiently possible with conventional hearing aids. These patients have enough cochlear reserve, but the additional middle ear disorder limits the usage of conventional hearing aids (gain limitation and distortion). The second possibility for such patients would be the bone conduction hearing aids, which indicate an insufficient gain for moderate to severe MHL. On the other hand because of good cochlear reserve there isn’t an indication for cochlear implantation. Therefore there is no optimal way to give an adequate gain to patients with moderate to severe MHL.
