Oro antral communication or fistula most commonly occurs due to extraction of upper maxillary molars including upper seccond premolars. There are various flaps for closure like buccal advancement flap, palatal pedical flap, and buccal fat pad flap etc. buccal fat pad is the excellent flap due to its excellent vascularisation and no loss of vestibular depth. We have so far operated 15 patients for oro antral fistulla using this buccal fat pad flap with no faliure. Patients and methods: A prospective study on fifteen randomly selected with age from 16 to 70 with fresh or old oro antral communication were closed with pedicle buccal fat pad flap. And every communication was closed using single flap without advancing the buccal flap therby no loss of vestibular depth. Conclusions: buccal fat pad flap is a versatile flap for closure of oroantral communication with high success and with no loss of vestibular depth.1
