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.

Myringoplasty is the closure of the perforation of pars tensa of the tympanic membrane. [1] [2] [3] When myringoplasty is combined with removal of scar tissue, it is called tympanoplasty. The operation is performed with the patient supine and face turned to one side. The graft material most commonly used for the surgery is temporalis fascia.
The oval perforation in this left tympanic membrane was the result of a slap on the ear four days previously. The sudden increased air pressure in the external auditory canal produced this traumatic blast perforation. Acoustic trauma is the sustainment of an injury to the eardrum as a result of a very loud noise.
In severe cases, middle ear hemorrhage or tympanic membrane rupture can result. [16] Tympanic membrane rupture: disruption of the eardrum. This can be caused by a blow to the ear, blast injury, barotrauma, or direct penetration of the tympanic membrane by an object entering the ear. [5]
Perforation of the tympanic membrane, rarely invasion of the middle ear Otomycosis is a fungal ear infection , [ 1 ] a superficial mycotic infection of the outer ear canal caused by micro-organisms called fungi which are related to yeast and mushrooms.
Tympanic membrane erythematous/inflamed: 7 to 10 days for complete resolution 3: Gross haemorrhage of the tympanic membrane: Six weeks needed for blood reabsorption 4 Extensive free blood in middle ear with bubbles visible behind tympanic membrane (haemotympanum) Six weeks needed for blood reabsorption 5: Perforation of the tympanic membrane ...
Tympanometry is an acoustic evaluation of the condition of the middle ear [1] eardrum (tympanic membrane) and the conduction bones by creating variations of air pressure in the ear canal. Tympanometry is an objective test of middle-ear function. It is not a hearing test, but rather a measure of energy transmission through the middle ear. It is ...
