Abstract
Oro-antral communication and subsequent formation of an oro-antral fistula (OAF) is a common complication that occurs during extraction of the maxillary molars and also as a result of operative procedure involving maxillary sinus. The incidence of this complication may vary from 0.31% to 3.8% after simple extraction of maxillary posterior teeth. Many procedures have been proposed for the closure of OAF. Local flaps are usually adequate to close minor to moderate size defects; these include buccal or palatal alveolar flaps and their modifications and buccal fat pad. This article describes the closure of an OAF in a 49-year-old male patient with buccal fat pad.
