Tympanoplasty using homograft tympanic membranes and ossicles. 1978

E E Campbell

The use of homograft materials in reconstructive, mastoid, and middle ear surgery is increasing. Not only are they useful and practical, but they also do the job well in both anatomical and functional restoration. Many encouraging reports have been written to support their use. Their advantages, in the opinion of the author, outweigh their cost since they can offer a more efficient, versatile, and better method of restoration of hearing in tympanoplasty surgery.

D009225	Myringoplasty	Surgical restoration of a perforated tympanic membrane by grafting. (Dorland, 28th ed.)	Myringoplasties
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.
