What may cause a tympanic membrane perforation?
A tympanic membrane perforation may be caused by any of the following: • Changes in ear pressure: An increase or decrease in the pressure inside your ears may damage your eardrums. Changes in ear pressure may occur when traveling on an airplane, or if you are involved in an explosion. Underwater sports such as swimming or scuba diving may also cause pressure changes in your ears. • Direct trauma to your eardrum: Trauma may occur when small objects are placed inside your ear. Having the object removed may also cause damage to your eardrum. • Ear infection: Infections in your middle ear are called otitis media (OM). Otitis media can be a short-term infection, or become a chronic (recurring) infection. Ear infections may cause fluid or pus to collect behind your eardrum. The fluid and pus may cause pressure in your ear and cause your eardrum to tear. • Head trauma: Any event that causes impact to your head may also damage your eardrums. Contact sports, car accidents, and falls are common
