Abstract: Introduction: Oro-antral fistula is an unnatural communication between the oral cavity and the maxillary sinus. This is a common phenomenon after dental avulsion, osteomyelitis, granulomatous diseases. Several surgical options exist for management. The aim of this study was to report the management of a case of oro-antral fistula after sequestrectomy. Clinical observation: A 60-year-old patient consulted our department for an endooral purulent discharge evolving for 6 months following a vestibular gingival swelling with regard to the 17th, 16th, 15th and 14th. The exooral examination was unremarkable. The endooral examination revealed poor oral hygiene, significant tartaric deposit, and generalized dyschromia. There was also a right vestibular gingival swelling with thick well under finger pressure. The exploration of the strait by the probe revealed the existence of a bone sequestration objectified by the orthopantomogram image. Sequestrectomy under local anesthesia resulted in an oral-sinus communication that was immediately repaired. The patient was subjected to antibiotic therapy. The anatomical pathological study of the bone sequestration revealed a benign fibroosseous lesion of the maxilla. After 15 days of follow-up, we found an oro-antral fistula that we secondarily repaired with mucoperiosteal flap surgery. The result was satisfactory after 21 days. Conclusion: In this study, the oro-antral fistula caused by sequestrectomy was successfully treated with a combination of antibiotic therapy and surgery under local anesthesia.
