Abstract

     Oroantral fistula (OAF) is an unnatural communication between maxillary sinus and oral cavity. It must be emphasized that unlike the oroantral communication, OAF is characterized by the presence of epithelium arising from the oral mucosa and/or from the antral sinus mucosa that, if not removed, could inhibit spontaneous healing. Generally, 10-15% of pathological conditions of the maxillary sinus were caused by dental origin. These complications occur most commonly during extraction of upper first and second molar. The major reason is the anatomic proximity orprojection of the roots to maxillary sinus. This case report presents oroantral fistula occurred after extraction of left upper first molar with sign of maxillary sinusitis. Treatments were irrigation with normal saline everyday and oral antibiotic. Buccal mucoperiosteum flap was taken to close the fistula. Four months later, communication did not resume, and the patient did not complain of pain, foul smelling, or purulent discharge and was satisfied with the outcome.
