MYRINGOPLASTY-GRAFT MATERIAL

Myringoplasty is the repair of damaged or perforated tympanic membrane. It has to be grafted to repair it. The commonly used graft materials are those which can be precured from the same person. The most common graft material used is temporalis fascia. This fascia covers the temporalis muscle. This fascia is chosen because of its easy approach and the fact that it is very thin but strong and resembles tympanic membrane. Secondly it can be harvested from the same post auricular incision which is used for post auricular approah for myringoplasty. Other common graft material used are vein graft, fascia lata, perichondrium and the tissue present above the temporalis fascia. cadeveric dura can also be used for this surgery.
