myringoplasty
Myringoplasty is the closure of the perforation of pars tensa of the tympanic membrane.〔(【引用サイトリンク】url=http://www.ent-surgeon.co.uk/operations/myringoplasty.htm )〕 When myringoplasty is combined with ossicular reconstruction, 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 tragal cartilage〔 and tragal perichondrium are also used as the graft by some surgeons.
Myringoplasty restores hearing loss in certain cases of tinnitus. The chances of re-infection and persistent discharge is less after surgery. Myringoplasty should not be performed if there is active discharge from the middle ear, or if the patient has uncontrolled nasal allergy, or when the other ear is dead and in children less than 3 years of age. Myringoplasty is often done under general anaesthesia, but it can be done under local anaesthesia also.
