Abstract: A fixation element secures to a patient's ear an implantable microphone having a cylindrical housing part with an acoustic inlet membrane after insertion into a hole which crosses a rear bony wall of the patient's auditory canal. The fixation element has a cylindrical sleeve part which surrounds the cylindrical housing part of the microphone and which has projecting, elastic flange parts which can be placed against the side of the wall of the auditory canal which faces the skin of the auditory canal. In use, the elastic flange parts are held in a bent position against an elastic restoring force of the flange parts, before implantation, by applying a holder to the flange parts which allows insertion of the flanges through the hole of the wall of the auditory canal.
