Type of Surgery
Last updated: 02/17/2009
Possible complications include failure of the graft to heal, causing recurrent eardrum perforation; narrowing (stenosis) of the ear canal; scarring or adhesions in the middle ear; perilymph fistula and hearing loss; erosion or extrusion of the prosthesis;...
dislocation of the prosthesis; and facial nerve injury. Other problems such as recurrence of cholesteatoma, may or may not result from the surgery.
Tinnitus (noises in the ear), particularly echo-type noises, may be present as a result of the perforation itself. Usually, with improvement in hearing and closure of the eardrum, the tinnitus resolves. In some cases, however, it may worsen after the operation. It is rare for the tinnitus to be permanent after surgery.
Tympanoplasty is reconstructive surgery for the tympanic membrane, or eardrum. There are several options for treating a perforated eardrum. If the perforation is from recent trauma, many ENTs 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 Â½ to 1 hour if done through the ear canal and 2â…“ 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.
Mastoidectomy is done to make the ear safe, since infection in the skull may be dangerous and can cause infection in and around the brain. With this procedure we hope to make the ear dry and possibly improve the hearing.
