ABSTRACT:
Ossicular replacement prostheses have heads of dome-like, mushroom-like, or irregular elliptoid, shapes which bear against the tympanic membrane of the ear to provide a large area of contact between the heads and membrane even when the prosthesis are tilted through large angles. The hollow shaft of the partial prosthesis receives the head of the stapes, while the solid shaft of the total prosthesis engages the base or footplate of the stapes of the ear.
