tympanoplasty

 [tim´pah-no-plas″te]
plastic reconstruction of the bones of the middle ear, with establishment of ossicular continuity from the tympanic membrane to the oval window. This surgical procedure is performed when chronic infection or tumor has led to destruction of the ossicles, of the pars petrosa of the temporal bone, or both. Because the ossicles are so small, the surgery must be done under magnification with an operating microscope. Tympanoplasty requires great surgical skill and the use of specially designed instruments. It is often done in preference to radical mastoidectomy and offers the advantage of greater preservation of hearing. (For patient care after tympanoplasty, see surgery of the ear.) adj., adj tympanoplas´tic.

tympanoplasty

ENT A technique of middle ear reconstruction intended to restore hearing, which consists of 2 components
1. Tympanic membrane engraftment, using various materials including canal skin, fascia, and homografts–eg, dura, periosteum, knee cartilage, ossicles and ossicular replacement with hydroxyapatite prostheses.

tympanoplasty

An operation to reconstitute a severed linkage in the chain of tiny bones (auditory ossicles) lying between the eardrum and the oval window of the inner ear, so as to restore hearing.

In our present study, a total of 20 cases underwent tympanoplasty with cortical mastoidectomy, of which 12 of the patients were females (60%), giving the female to male ratio to be (F:M) 1.5:1.
Tympanoplasty with allogeneic ossicles can restore hearing to levels comparable to autograft, and hearing benefit is often favourable to prostheses.
