Detailed Description:
A new technique, called Direct Acoustic Cochlear Stimulation, has very recently been introduced to restore hearing in patients with severe hearing loss due to the immobility of a small ossicle in the middle ear, the stapes. A piston-like prosthesis, which is placed up into the inner ear, is connected to an implantable mechanical stimulator, named DACS. Unfortunately, as with other active middle ear implants, until now the correct function of this technique cannot be checked during the surgery, leading to a possibly variable outcome of hearing. In this project, the objective auditory evoked potentials, like Auditory Steady-State Response (ASSR), will be used to measure the efficacy of this method of inner ear stimulation. This highly innovative, non-invasive research will provide valuable insight in a new promising way of inner ear stimulation and may give a unique possibility to measure the correct connection from an implantable hearing device to the inner ear.
