Synopsis

Tympanosclerosis is characterized by the formation of dense connective tissue in the tympanic membrane and structures of the middle ear that manifests as whitish / yellow plaques. It does not necessarily cause or lead to loss of hearing; it may be asymptomatic.

The condition may manifest as calcification and scarring from chronic inflammation and otitis media. Myringosclerosis may be caused by placement of a polyethylene tympanostomy tube, resulting in the formation of retraction pockets in the tympanic membrane. Involvement of the ossicles can lead to conductive hearing loss. Inflammation can lead to the formation of adhesions (adhesive otitis) and result in damage to the ossicles (cholesteatoma, etc).
