| Abstract | ||||
| Background: oroantral fistulas (OAFs) are pathological communications between oral cavity and maxillary sinus that occurs during extraction of upper posterior teeth. With increasing demand for Implant rehabilitation, bony closure of the OAF is required. Purpose: the aim was to assess simultaneous closure of oroantral fistula with sinus linning repair using chin bone graft. Patients and methods: this study was conducted on twelve patients had OAF following extraction of maxillary posterior teeth. Patients were collected from department of Oral and Maxillofacial surgery, Faculty of Dentistry, Tanta University. The sinus linning was repaired using fistulous tract which dissected and rotated into the sinus membrane, then the bony defect was grafted with autogenous corticocancellous chin graft and platelet- rich fibrin membrane and graft was covered with buccal advancement flap. Patients were followed up clinically after 1, 2 weeks, 1,3 and 6 months to evaluate closure of the fistula. Radiographic evaluation was performed immediate and 6 months postoperatively using C.B.C.T to evaluate the fate of bone graft. Results: Successful closure of the OAF was achieved in 11 cases, only one case (case no. 3) showed wound dehiscence and graft exposure immediate postoperatively and the wound not healed so, by the end of the 1st month we removed the graft and the wound was closed with buccal advancement flap. Radiographically: evaluation using C.B.C.T after 6 months when compared to immediately after surgery showed complete healing of the bone defect with non- significant increase in both bone density and alveolar bone height for 11 cases | ||||
