Buccal Myomucosal Flap and Buccal Pad of Fat for the Closure of Oro-antral Fistula

Oroantral fistula (OAF) is a pathological communication between the oral cavity and the maxillary sinus. A variety of surgical techniques have been developed, with recurrence rates of up to 33%7, mainly due to wound contraction and postoperative infection. To increase the success rates of OAF closure procedures, the use of double-layered closure techniques has developed, but most of these techniques alter the original oral anatomy and may result in significant postoperative morbidity.

Treatment and study plan

Double layer of buccal myomucosal Flap and buccal pad of fat

Procedure

The buccal myomucosal flap will be harvested from cheek below stenson papilla and will be sutured over buccal pad of fat which will be sutured at palatal mucosa after complete curettage of infected fistulous tract.
