Oroantral communication/fistula is one of the complication of dentoalveolar procedures that needs surgical intervention.Aim
This study focused on evaluation of layered closure of oroantral fistula by using buccal fat pad (BFP) and buccal advancement flap.Patients and methods
Fifteen participants were enrolled in the study. Preoperative assessment included the clinical history of the patients and physical and radiographic examination. The fistulas were closed using BFP and buccal advancement flap.Results
The postoperative course was uneventful. All cases healed satisfactorily with a success rate of 100%. BFP is mobilized easily, being in the same surgical field. It is well vascularized and epithelialized at a considerable rate resulting in no morbidities.Conclusion
Layered closure of oroantral fistula by using BFP and buccal advancement flap can prevent obliteration of vestibular depth.
