An auditory ossicle prosthesis (10) with a sound transmitting prosthesis body (13) which at one end has a first coupling element (11) and at the other end a second coupling element (12) is characterised in that a stabiliser element (14) is provided which is designed for fixation of the auditory ossicle prosthesis in its implanted state on a level with the plane of the tympanic membrane and for stabilising the position of the implanted auditory ossicle prosthesis in the middle ear, whereby the stabiliser element is adapted for permanent and stable securing at the first coupling element or at a section of the prosthesis body adjacent to the first coupling element and comprises a fixation part (14.2) for anchoring the stabiliser element at one or more places of the ear canal wall. Thereby, the auditory ossicle prosthesis stays spatially fixed within very small variations in its initial position after implantation inside the middle ear cavity providing effective protection against post-operative dislocation, tilting or tipping of the prosthesis and without deteriorating the sound transmission properties of the prosthesis by the mechanical stabilization measures.
