Abstract

Oroantral fistula is a pathological communication between oral cavity and maxillary sinus. There are many treatment modalities of closure of oroantral fistula and communication. We found double layer closure using buccal fat pad (BFP) and buccal advancement flap as most effective technique in large defects. Since the procedure was first described by Egyedi and has been reported in literature thereafter. In this article we present a case report of a 37 year old male patient who was suffering from oroantral fistula and was managed by double layer closure using BFP and buccal advancement flap.
