Tratamento da infecção aguda bacteriana pós cirúrgica em elevação sinusal: Relato de caso.

Introduction: Infection of the sinus graft with consequent acute bacterial rhinosinusitis (ABRS) is a complication that can occur during the postoperative period of sinus augmentation surgery. A small group of bacteria seems to predominate in ABRS, and these bacteria are empirically susceptible to tetracycline antibiotics, preventing the presence of resistant strains. Historically, clinicians have mixed tetracycline with various biomaterials or hydrated biomaterials in a diluted solution of tetracycline in the treatment of periodontal disease and for crest preservation / enlargement indications. Case presentation: In the present case, a 39-year-old African American man with sinus graft infection and signs and symptoms consistent with ABRS was successfully treated by removing the initial material from the graft, completely debriding and irrigating the antrum and placing a lyophilized allograft bone hydrated in an aqueous solution of tetracycline. Conclusion: Given the typical bacteria present in ABRS, tetracycline applied locally can be useful prophylactically in sinus lift surgery or as an adjunct in the treatment of postoperative sinus graft infection.
