Abstract
A support for input and output transducers of a hearing aid is implanted in the middle ear. The support, which is attached to the mastoid bone, can be a single component or comprise two adjustable components. In one embodiment, an arm extends from the proximal end of the support towards an access hole created behind the outer ear, where the arm is attached for further stability. In another embodiment, the arm extends outside the access hole, where it is mounted subcutaneously to the mastoid bone with a mechanical fastener. The support provides positional adjustability, stability, and is invisible externally.
