The use of palatal flaps has been documented for treating such fistulae. The presence of the oroantral fistula at the area of second molars or maxillary tuberosity could complicate the use of the palatal rotational flap where the arch of its rotation is increased leading to compromised blood supply. The use of the buccal flap is not advocated because it is very thin. Rationale Double or triple-layer closure is indicated to avoid recurrence of the COAF. Different layers have been documented to minimize the risk of recurrence and reinforce buccal flaps. The oral tissues at the oral side of the oroantral fistula could used as an additional l
