Abstract: Ossicular prostheses for total reconstructive surgery of an infection-destroyed or traumatically damaged middle ear. Each prosthesis comprises a pair of cooperating assemblies which are adapted to be extended between the tympanic membrane and the fenestra vestibuli (oval window) in replacement of the auditory ossicles, namely the malleus, incus, and stapes. In the best mode a first rigid, preferably stainless steel shaft is pivotally received by a flanged socket surgically secured to the ear drum. Flanged socket structure secured surgically to the oval window receives the balled end of an outwardly projecting, rigid, generally tubular shaft. The extreme end of the latter shaft is adapted to be axially mated with the first shaft which is coaxially, slidably telescoped thereto. In an alternative embodiment each of the two cooperating assemblies preferably comprises elongated shaft structure including twin, parallel, closely-spaced shaft members which originate from an integral loop-like base.
