Comparing the Efficacy of Platelet-Rich Fibrin (PRF) With the Buccal Advancement Flap for the Closure of Acute Oroantral Communication

Oroantral communication (OAC) is a pathological communication between the oral cavity and the maxillary sinus. Numerous methods are described to manage an acute OAC with some adverse effect and limitations. Our comparative cross-sectional study tried to evaluate the efficacy of Platelet-rich fibrin (PRF) by comparing with the Buccal advancement flap for the closure of acute OAC on 38 patients (n=38), were divided into two groups. One group treated by traditional Buccal advancement flap and compared with the group treated with PRF clot and membranes. Statistically significant better healing with less complication was observed (P< 0.05) in group treated with PRF clot and membranes considering as an effective way to manage acute oroantral communications.

Three-Layered Closure of Persistent Oroantral Fistula Using Chin Graft, Buccal Fat Pad, and Buccal Advancement Flap: A Case Report with Review of Literature

Various techniques have been used for the repair of oroantral fistula (OAF) but majority of them have focused on the soft tissue closure alone, and most of the time, the osseous floor of the sinus was ignored. Existing literature supports that bone grafts supported by Buccal Fat Pad (BFP) heal well without undergoing significant resorption and necrosis. Through this case report, we wish to elaborate on the clinical success of using BFP and autogenous chin graft for simultaneous reconstruction of a large long-standing oroantral fistula with underlying osseous defect. The combination technique can prove beneficial for osseous regeneration of sinus floor and improve chances for future implant prosthetic rehabilitation.
