VINÍCIUS RODRIGUES GOMES, JOSFRAN DA SILVA FERREIRA FILHO, RICARDO FRANKLIN GONDIM, BRENO SOUZA BENEVIDES

The maxillary sinusitis is characterized by the infection of this paranasal sinus, causing dysfunction, pain, bad odor and fever. The oro-sinusal fistula represents a complication in which communication occurs between the maxillary sinus and the buccal cavity. The objective of this study is to report the case of a 45 years-old male patient, who sought a clinic of Oral and Maxillofacial Surgery presenting history of traumatic tooth extraction #17, complaining of: liquid flux from the mouth into the nasal cavity and pain, with an evolution time of approximately four months. Intraoral clinical exam showed the absence of teeth #16 and #17, fistula associated with these alveolar ridge and positive outcome of the Valsalva maneuver. Imagiologic exams showed continuity between the oral cavity and right maxillary sinus, with extensive opacification. Before the diagnostic confirmation of maxillary sinusitis and buco-sinusal fistula, the right sinusectomy and closure of the fistula were planned by sliding the buccal adipose flap. Currently the patient is in 90-day follow-up, in which the fistula is enclosed and regression of the associated symptoms. The treatment course proved to be safe and effective for solving this case.
