Craniofacial osteomyelitis in a patient with systemic involvement: a case report

Abstract

This report presents the case of a 61-year-old male patient with diabetes, hypertension, and a history of severe COVID-19 with osteomyelitis of the frontal sinus and upper jaw. The patient reported intense pain in the facial and maxillary area for two months. The computed tomography images showed mucoperiosteal thickening of the maxillary sinus and the magnetic resonance imaging showed multiple lytic lesions at the frontal sinus level, as well as brain abscesses in the left frontal region that were correlated with the microbiological cultures. In the intraoral clinical examination, segments with a necrotic appearance of the upper jaw, orosinusal fistula and multiple dental infectious foci were observed. The patient was treated with antibiotics, analgesics, antiinflammatories, insulin, and proton pump inhibitor. Trephination of the frontal sinus, drainage of the abscess and sequestrectomy in the maxilla were performed and sessions with a hyperbaric chamber were ordered.
