TORPs and PORPs in tympanoplasty. 1978

J L Sheehy

In an attempt to improve results in ossicular reconstruction, a newly introduced material, PlastiPore, has been evaluated over a short term. The techniques employed are described in detail and the use of a lateral covering material such as tragal cartilage is advocated as a means of preventing extension of this foreign material. The results in over 100 ears are better than those obtained with previous methods.

UI MeSH Term Description Entries
D010046 Oval Window, Ear Fenestra or oval opening on the lateral wall of the vestibular labyrinth adjacent to the MIDDLE EAR. It is located above the cochlear round window and normally covered by the base of the STAPES. Oval Window of Ear,Oval Windows, Ear
D011095 Polyethylenes Synthetic thermoplastics that are tough, flexible, inert, and resistant to chemicals and electrical current. They are often used as biocompatible materials for prostheses and implants. Ethylene Polymers,Ethene Homopolymers,Homopolymers, Ethene,Polymers, Ethylene

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.

D013199 Stapes One of the three ossicles of the middle ear. It transmits sound vibrations from the INCUS to the internal ear (Ear, Internal see LABYRINTH).

D014184 Transplantation, Homologous Transplantation between individuals of the same species. Usually refers to genetically disparate individuals in contradistinction to isogeneic transplantation for genetically identical individuals. Transplantation, Allogeneic,Allogeneic Grafting,Allogeneic Transplantation,Allografting,Homografting,Homologous Transplantation,Grafting, Allogeneic
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.
