Rupture or perforation (hole) of the eardrum can occur in 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.[1]
Perforation of the eardrum leads to conductive hearing loss.
The perforation may heal in a few weeks, or up to a few months.[2] Some perforations require intervention - this may use a paper patch to promote healing (simple procedure in the office of an ear, nose and throat specialist), or surgery (tympanoplasty).[3][4] However, in some cases, the perforation can last several years and will be unable to heal naturally - usually a result of a perforation being surgically induced during an operation involving the ear.
Hearing is usually recovered fully, but chronic infection over a long period may lead to permanent hearing loss. Those with more severe ruptures may need to wear an ear plug to avoid water making contact with the ear drum.
