Tympanoplasty: TORPS and PORPS. 1979

D E Brackmann, and J L Sheehy

We reviewed 106 cases in which PlastiPoreTM prostheses were used for ossicular reconstruction. In all cases a piece of cartilage was interposed between the prosthesis and the tympanic membrane graft to prevent the potential problem of prosthesis extrusion. With total ossicular replacement prostheses (TORPs) 55% closed to within 10 db and 85% closed to within 20 db of the bone conduction level. Closure to within 10 db of the bone conduction level was accomplished in 64% of partial ossicular replacement prostheses (PORPs) cases. These results are better than obtained previously with either ossicles or cartilage alone.

D004429 Ear Ossicles A mobile chain of three small bones (INCUS; MALLEUS; STAPES) in the TYMPANIC CAVITY between the TYMPANIC MEMBRANE and the oval window on the wall of INNER EAR. Sound waves are converted to vibration by the tympanic membrane then transmitted via these ear ossicles to the inner ear.

D014433 Tympanoplasty Surgical reconstruction of the hearing mechanism of the middle ear, with restoration of the drum membrane to protect the round window from sound pressure, and establishment of ossicular continuity between the tympanic membrane and the oval window.

D019736 Prostheses and Implants Artificial substitutes for body parts, and materials inserted into tissue for functional, cosmetic, or therapeutic purposes. Prostheses can be functional, as in the case of artificial arms and legs, or cosmetic, as in the case of an artificial eye. Implants, all surgically inserted or grafted into the body, tend to be used therapeutically. IMPLANTS, EXPERIMENTAL is available for those used experimentally.
