Tympanosclerosis is a peculiar form of chronic disease of the middle ear with the formation of white hyaline (sclerotic) masses in the eardrum and the tympanic cavity. The etiology of tympanosclerosis is apparently a long-lasting acute inflammation of the middle ear in early childhood. The main complaint is hearing loss (often pronounced). Some patients have mucous, rarely purulent, discharge from the ear. Otoscopic changes are similar to those observed with adhesive otitis media (see). Sometimes white deposits are visible both in the eardrum itself and (if there is a perforation) in the tympanic cavity. Hearing loss (in a functional study) is characteristic of damage to the sound-conducting apparatus of the ear. Treatment of tympanosclerosis surgical - tympanoplasty (see).
