Abstarct:
Oroantral communication can be defined as a pathologic opening created between the oral cavity and the maxillary sinus. It mostly results from the extraction of upper molars and premolars. If left untreated, it may lead to an oroantral fistula and/or maxillary sinusitis. Several modalities have been described for the management of this communication. The most employed surgical flaps involve advanced buccal flap, palatal flap, and buccal fat pad flap. Yet, these techniques have shown advantages as well as limitations . The treatment of oroantral communication using a rotational crestal flap in conjunction with platelet-rich fibrin (PRF) represents an innovative technique that integrates the benefits of PRF with a minimally invasive surgical approach.
