Abstract
Oroantral communications (OAC) are probable surgical complications of dentoalveolar procedures. OACs 2mm in diameter or smaller are likely to close spontaneously without the need for any surgical intervention. However, OACs 3mm in diameter or larger, or OACs associated with maxillary or periodontal inflammation, may persist, and surgical closure is recommended. Various surgical techniques have been suggested for the closure of oroantral defects. We have found the technique of two layer closure with buccal fat pad (BFP) and buccal mucoperiosteum quite useful for closure of chronic Oroantral fistula (OAF) and this article reports a case of OAF in the left first molar region of a 50year old male, which has been closed successfully with this technique. Buccal fat pad is a pedicled locally available flap which has its own blood supply and hence can be used with great efficacy in closure of OAF. This paper aims to elaborate the surgical details of this technique and its usefulness in closure of chronic OAF.
