Tympanic membrane perforation

Summary of Tympanic membrane perforation

A perforated or punctured eardrum is a rupture or perforation of the eardrum which can occur as a result of otitis media, 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.
