ABSTRACT:
An ossicle prosthesis includes, at one end, a first fastening element designed as a top plate for mechanical connection with the tympanic membrane, and, at the other end, a second fastening element for mechanical connection with a component or parts of a component of the ossicular chain or with the inner ear, and a connecting element that connects the two fastening elements with each other in a sound-conducting manner; the top plate includes a radially outward annular region, a radially inward attachment region for mechanically attaching the top plate to the connecting element, and several segment elements for radially connecting the annular region with the attachment region, characterized by the fact that the segment elements are geometrically designed such that they locally emulate any localized medial motions made by the tympanic membrane, but they do not transmit the motion to distant regions of the top plate. As a result, a high level of post-operative flexibility and variability of the prosthesis, and higher-quality sound conduction through the prosthesis may be attained in a technically simple, uncomplicated, and cost-favorable manner.
