[timpan′əplas′tē]

Etymology: Gk, tympanon + plassein, to mold

any of several operative procedures on the eardrum or ossicles of the middle ear designed to restore or improve hearing in patients with conductive hearing loss. These operations may be used to repair a perforated eardrum, for otosclerosis, or for dislocation or necrosis of one of the small bones of the middle ear. See also myringoplasty, stapedectomy.

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.
