 TORP (total ossicular replacement prosthesis), which is a composite of teflon polymer and elemental carbon, has been widely used in reconstructive surgery of the middle ear. Unfortunately, there are cases in which the prosthesis shows post-operative extrusion. In order to evaluate the fate of TORP within the human middle ear, the extruded TORPs were histopathologically examined under light and scanning electron microscope. It appears that TORP causes less inflammatory and foreign body reaction, and its ultraporous nature allows fibrous tissue ingrowth. Since the risk of the extrusion can be prevented with the use of a piece of cartilage between the TORP and the eardrum, it is concluded that TORP shows an useful artificial ossicle in tympanoplasty.
