Tympanosclerosis.Tympanosclerosis occurs when deposits of hyalinized and often calcified Calcified Hardened by calcium deposits. Mentioned in: Heart Valve Repair fibrotic granulation tissue appear in the middle ear, epitympanum, and tympanic membrane. The deposition of calcium and phosphate crystals follows the invasion of fibroblasts into the submucosal layers of the middle ear. These fibroblasts thicken and fuse into homogenous masses. The suspensory ligaments and tendons of the ossicles Ossicles The three small bones of the middle ear: the malleus (hammer), the incus (anvil) and the stapes (stirrup). These bones help carry sound from the eardrum to the inner ear. Mentioned in: Otitis Media, Stapedectomy can degenerate as a result of chronic otitis media, and they can subsequently calcify cal·ci·fy v.

[1] On computed tomography, tympanosclerosis can appear as unifocal or multifocal masses or as linear calcific densities in the middle ear cavity, epitympanum, or in the tympanic membrane. Such were the circumstances in the case presented here (figure). Reference (1.) Valvassori GE, Buckingham RA.
