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.
