Tympanosclerosis (TS) is a fairly common but radiographically underrecognized cause of postinflammatory ossicular fixation and noncholesteatomatous conductive hearing loss. Pathologically it represents submucosal deposition of fibrous or calcium within the tympanic membrane, middle ear and rarely the mastoid. 
 Some investigators report an association with chronic secretory otitis media to be as high as 25%. A history of ventilation tubes and tympanic membrane perforation likewise put patients at risk.  Radiologists should be aware of these associations and TS should strongly be suspected, particularly if there is a history of significant conductive hearing loss with imaging features of chronic otitis. 
 Clinically significant lesions can be subtle at imaging, but areas of hyperdensity associated with the tympanic membrane, ossicular chain, ligaments and middle ear should raise suspicion. The focus of this exhibit is to review the radiologic features of TS, emphasizing relevant anatomy, pathologic correlation and treatment options.

Introduction to TS Clinical presentation of TS Review temporal bone anatomy, emphasizing relevant anatomy affected by TS Illustrate the imaging spectrum of TS Introduce interpreters to treatment options for the disease.
