Introduction: This report compares the use of a buccal fat pad (BFP) to Oro-Antral–Fistula (OAF) closure.
Materials & Methods: BFP was used as a pedicle graft to OAF closure in 13 patients. Five of the patients underwent primary closure with BFP and 8 patients were treated with BFP after an unsuccessful closure with a buccal advancement flap. The BFP was left uncovered to epithelialize in all patients.
Results: The BFP healed without complication within 3 to 4 weeks in all patients. The surface of the fat converted to normal mucosa.
Conclusion: The findings support the idea that BFP is a useful, safe, and easy method to close OAF, especially recurrent OAF.
