ORAL-SINUSAL COMMUNICATION CLOSURE WITH BICHAT BALL: CASE REPORT

Abstract

Introduction: Oral sinus communication (CBS) is characterized as a complication that can occur in upper molar surgeries, causing a rupture of the sinus lining, bone defect and opening of the gingival tissue, which need to be closed and completely isolated from the oral environment and adjacent tissue. With the presence of infectious conditions in the maxillary sinus, initial therapeutic treatment of this condition through antibiotic therapy for a period of 14 to 21 days becomes mandatory. On the other hand, when the extension is equal to or greater than 3 mm in diameter, or presents an inflammatory or infectious process related to the existing period of time of CBS, the surgical procedure is the most indicated, requiring the use of rotation and flaps for sealing, as well as the use of Bichat Adipose Body. Case report: Female patient, 62 years old, Caucasian, sought dental care at the Oral and Maxillofacial Surgery service at Hospital Universitário Oswaldo Cruz, Recife, Brazil, complaining of pain after extraction in the posterior region of the left maxilla. The intraoral physical examination revealed a completely edentulous maxilla, depression in the premolar region on the left side and phlogistic signs in the underlying tissues. The patient in question was prescribed pre-surgical antibiotic therapy with amoxicillin 500mg with potassium clavulanate 125mg every 8 hours for 10 days, with the aim of controlling the infectious condition present in the maxillary sinus and avoiding postoperative complications. Final Considerations: The clinical case discussed corroborates the literature, demonstrating that the use of the Bichat ball is an acceptable, versatile type of reconstruction with a simple surgical technique, presenting an extremely satisfactory result.
