FECHAMENTO DE COMUNICAÇÃO BUCO-SINUSAL UTILIZANDO O CORPO ADIPOSO BUCAL: RELATO DE CASO CLÍNICO.

Introduction: Bucosinusal communications are relatively frequent surgical complications in dental practice. Although several conditions are related to this type of communication, the exodontia of upper posterior teeth presents as the main etiological factor. They are diagnosed through fistulas, which communicate the buccal and sinus cavities, thus allowing the passage of food and other substances into the maxillary sinus, thus providing infectious pictures known as Sinusites. Objective: through the report of a clinical case of buccosalusal fistula, we will focus on the success of the closure of buccomasinal communication with Bichat Adipose Body. Technique report: male patient, 59 years old, leucoderma, with no systemic alterations, who attended the University of the Sacred Heart Postgraduation outpatient clinic reporting as a main complaint the fact of "getting fluids through the nose" during feeding and that this had started after performing a residual root exodon of element 16. It also reported that after the exodontia, an attempt was made to close the buccosinusal fistula through the repositioning of the vestibular flap and no success was achieved. After 45 days of conditioning the maxillary sinus mucosa through irrigations with saline solution and 0.12% chlorhexidine, the patient was proposed and the buccosinusal fistula was closed using the Bichat Adipose Body. Conclusion: Today, in order to achieve the high success rate in the closure of buscossinusal communications, we use the Bichat Adipose Body, because it is a simple procedure and provides satisfactory results for the patient.
