What are calcification patches on the eardrum often associated with?

Calcification patches on the eardrum, also known as tympanic membrane, are often associated with prior ear infections. These patches represent areas of disruption in the normal tympanic membrane structure, which can occur as a result of inflammatory processes during an infection. When the eardrum experiences repeated infections, it can lead to scarring and calcification due to the healing process. As the body responds to irritation and inflammation caused by infections, the deposition of calcium salts can result in these patches.

In contrast, aging typically leads to a variety of changes in the ear, but calcification specifically related to the eardrum is more directly linked to the history of ear infections. Cochlear dysfunction usually involves issues related to the inner ear and is less likely to be connected with the appearance of calcification on the eardrum. Noise exposure can affect hearing but does not generally lead to calcifications on the tympanic membrane itself.
