ABSTRACT
The oroantral fistula is one of the complications that might occur following extraction of upper posterior teeth. The use of pedicled buccal fat pad graft has recently been considered in the treatment of oroantral fistula. The aim of this article was to evaluate using pedicled buccal fat pad flap for closure of oroantral communications. In this experimental study [case series], thirteen patients [11 male and 2 female] with oroantral communications, which either developed following the extraction of maxillary posterior teeth or odontogenic cyst removal, with an average age of 34.06 [24-52 years old], were treated with a pedicled buccal fat pad graft. Surgeries were performed under local or generalized anesthesia. All of patients were evaluated for maxillary sinus infection before and 6 months after surgery with Water's radiography. Clinical repair of wound was evaluated at the first and the second week and 6 months after the operation. Oroantral communication was treated successfully in all patients. Only one patient complained from pain and nasal obstructions six months following surgery. Pedicled buccal fat pad graft can be successfully used for closure of oroantral communication
