| Abstract:

Oroantral fistula (OAF), most commonly termed as oroantral communication, is the abnormal condition in which there is a communicating tract between the maxillary sinus and the oral cavity. Oro-antral communications and fistulas are complications frequently encountered by oral and maxillofacial surgeons as a complication most commonly during extraction of upper molar and premolar teeth (48%). Other causes include tuberosity fracture, dentoalveolar/periapical infections of molars, implant dislodgement into maxillary sinus, trauma (7.5%), presence of maxillary cysts or tumors (18.5%), osteoradionecrosis, flap necrosis, dehiscence following implant failure and sometimes as a complication of the Caldwell-Luc procedure. The aim of this article is to describe OAF, introduce the approach algorithm for the treatment of OAF; and review the fundamental surgical techniques using local flaps for fistula closure with their advantages and disadvantages. Databases of PubMed central register of randomised controlled trials were searched for related studies along with a complementary manual search for relevant journals. Data extraction and collection from the included studies was conducted by the primary author and reviewed by the second author. It can be concluded that long term treatment for oro antral fistulas are by the use of with resorbable PLGA-coated -TCP root analogs, hemostatic gauze and local flaps which have all proved to be effective and longer lasting without secondary infection and recurrence. The most effective from literature among the local flaps is the buccal sliding flap.
