Management of Oro-antral fistula by double flap technique: A case report.

Brief Background Oro-antral fistula (OAF) is a pathological communication between oral cavity and maxillary sinus which usually occurs due to traumatic extraction of maxillary molars, or dentoalveolar fractures of posterior maxilla, or osteomyelitis or pathologies involving the maxillary bone. Material The most commonly employed flaps for management of oro-antral fistula are buccal advancement flap and palatal rotation flap. Since there are various advantages of buccal pad of fat, therefore it was incorporated with the buccal flap. This case report revealed a case of double layer closure of oro-antral fistula using buccal pad fat and buccal advancement flap Discussion This is easily graft harvested under local anesthesia that enhances its simplicity and versatility. The technique of harvesting the buccal fat pad consists of blunt and gentle dissection with curved artery forceps behind the maxillary tuberosity region. Since Buccal fat pad resides below the Buccinator muscle. It is always recommended that attempts should be made to maintain the capsule of the buccal fat as the blood supply resides within its capsule Summary and Conclusions We can conclude that double-layered closure using buccal fat pad with buccal advancement flap provides a better stability and it also enhances wound healing of surgically repaired Oro -Antral fistula.
