Common flaps to accomplish this closure include buccal advancement flap, buccal fat pad flap, buccal advancement closure over a metal foil, palatal rotation flap and palatal is- land flaps.3 Larger flaps including temporalis and free tissue transfer might be required for larger fistulae, as resulting from ablative surgery or traumatic loss of posterior maxilla.
