A Double Barrier Technique in Surgical Closure of Oroantral Communication

Abstract

Routine minor surgical procedures in the maxillary premolar or molar region often heal without any repercussions; however, some may culminate in an unintentional opening into the maxillary sinus, leading to the formation of oroantral communication. It is, therefore, imperative for a surgeon to recognize it and treat it sequentially to avoid long-term complications. This case report highlights a flapless double membrane closure of oroantral communication (OAC) with platelet-rich fibrin (PRF) and guided tissue regeneration (GTR) membranes and its edge over conventional methods.

Treatment of Odontogenic Maxillary Sinusitis with the Use of Growth Factors in Advanced Platelet-Rich Fibrin for Immediate Closure of Oro-Antral Communication: A Case Report

“…The most frequently utilized treatment for OAC and OAF involves a combination of platelet-rich fibrin and a tension-free buccal flap, or alternatively, the sole use of PRF. The results of treatment with growth factors were very good and all patients had good healing in follow-up [30][31][32][33][34][35][36][37][38][39][40][48][49][50][51][52][53][54][55]. In our patient, we also achieved very good treatment results and, additionally, healing of inflammatory lesions in the maxillary sinus in the case of odontogenic chronic sinusitis.…”

The double-barrier technique using platelet-rich fibrin for closure of oroantral fistulas

“…In the current study, bone defect regeneration did not take place. However, Pal et al reported that use of PRF along with a guided tissue regeneration membrane to close the OAF can result in thin bone formation within the defect 20 . Therefore, further study for simultaneous or secondary sinus augmentation may be needed to create bony support for potential placement of dental implants.…”
