Perforated eardrum

（重定向自Tympanic membrane perforation）

A perforated eardrum or punctured eardrum is a rupture or perforation (hole) of the eardrum which can occur as a result of otitis media (ear infection), trauma (e.g. by trying to clean the ear with sharp instruments), explosion, loud noise or surgery (accidental creation of a rupture). Flying with a severe cold can also cause perforation due to changes in air pressure and blocked eustachian tubes resulting from the cold. This is especially true on landing.
