About

Oroantral fistula (OAF) is a pathological communication between the oral cavity and the maxillary sinus. A variety of surgical techniques have been developed, with recurrence rates of up to 33%7, mainly due to wound contraction and postoperative infection. To increase the success rates of OAF closure procedures, the use of double-layered closure techniques has developed, but most of these techniques alter the original oral anatomy and may result in significant postoperative morbidity.
