Abstract
INTRODUCTION: Oroantral fistula is an epithelialized, pathological and unnatural communication between the oral cavity and the maxillary sinus. OBJECTIVES: The aim of this study was to evaluate the use of buccal antrostomy bone as a graft for closure of oroantral fistula clinically and radiographically. MATERIALS AND METHODS: A prospective study was done on 10 patients complaining of oroantral fistulae following extraction of maxillary posterior teeth. The bony defect of the oroantral fistula was closed by anterior wall of maxillary sinus as a graft material and fixed to the surrounding bone using N-Butyl-2-Cyanoacrylate (Histoacryl®), then covered by buccal advancement flap. The patients were followed up clinically after 4, 6, 8 and 12 weeks postoperatively Radiographic evaluation was performed by cone beam computed tomography (CBCT) preoperatively and after 12 weeks postoperatively. RESULTS: Evaluation of the patients revealed that proper healing of the wound occurred in most of the patients except in 3 patients whose bone graft was exposed and removed. Radiographicaly, significant amount of bone was formed comparing the preoperative and postoperative CBCT of the patients. CONCLUSIONS: According to the results of the present study, it is concluded that the use of the buccal antrostomy wall as a bone graft fixed with N butyl cyanoacrylate proved successful results in closure of large oroantral fistula.
