Tympanoplasty is the surgical operation performed for the reconstruction of the eardrum (tympanic membrane) and/or the small bones of the middle ear (ossicles). The term 'myringoplasty' refers to repair of the tympanic membrane alone[1].

There are several options for treating a perforated eardrum. If the perforation is from recent trauma, many ear, nose and throat specialists will elect to watch and see if it heals on its own. After that, surgery may be considered. Tympanoplasty can be performed through the ear canal or through an incision behind the ear. The surgeon takes a graft from the tissues under the skin around the ear and uses it to reconstruct the eardrum. One of the most common graft sites is from the tragus. The surgery takes ½ to 1 hour if done through the ear canal and 2⅓ to 3 hours if an incision is needed. It is done under local or general anesthesia. It is done on an outpatient basis and is successful 85-90% of the time.

History

The first recorded attempt at repairing the tympanic membrane was made by Marcus Banzer[2] in 1640 using an ivory tube covered by pig's bladder.

Artificial tympanic membranes

In the middle of the nineteenth century the British otologists James Yearsley and Joseph Toynbee each developed their own form of artificial eardrum. Despite initial enthusiasm for these devices, experience amongst the medical profession over the following half century demonstrated their minimal value in the treatment of a perforated eardrum[3].
