Perforated eardrum

Injury leading to a hole in the eardrum

A perforated eardrum (tympanic membrane perforation) is a prick in the eardrum. It can be caused by infection (otitis media), trauma, overpressure (loud noise), inappropriate ear clearing, and changes in middle ear pressure. An otoscope can be used to view the eardrum to diagnose a perforation. Perforations may heal naturally or require surgery.

A perforated eardrum leads to conductive hearing loss, which is usually temporary. Other symptoms may include tinnitus, ear pain, vertigo, or a discharge of mucus. Nausea and/or vomiting secondary to vertigo may occur.

An otoscope can be used to look at the ear canal. This gives a view of the ear canal and eardrum, so that a perforated eardrum can be seen. Tympanometry may also be used.

A perforated eardrum often heals naturally. It may heal in a few weeks or may take up to a few months. and popularized by the Jim Sheehy at the House Ear Institute. Endoscopic tympanoplasty, usually using the endoscope through the ear canal without the need for incision. This technique was introduced and popularized by Professor Tarabichi of TSESI: Tarabichi Stammberger Ear and Sinus Institute. The success of surgery is variable based on the cause of perforation and the technique being used. Predictors of success include traumatic perforation, dry ear, and central perforations. Predictors of failure includes young age and poor eustachian tube function. The use of minimally invasive endoscopic technique does not reduce the chance of successful outcome. 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 prevent water contact with the ear drum.
