ABSTRACT
INTRODUCTION: Osteomyelitis is an inflammatory-infectious state that may involve trabecular bone, cortical bone, bone marrow and periosteum. The source of the infection may be hematogenic, acquired from an adjoining infectious focus or by direct inoculation into the bone. Its treatment involves antibiotic administration and surgery, but its management remains challenging. PRESENTATION OF CASE: A 76-year-old male patient with a history of car accident 3 months earlier sought hospital care with nasal fracture and loss of substance in the right frontotemporal region, where a pectoral muscle free graft was performed to reconstruct the facial defect. The grafted region had hyperemic edges, necrotic appearance, purulent discharge and bone exposure in the nasal dorsum. The initial diagnostic hypothesis was an infectious process due to graft rejection, with likely evolution to osteomyelitis. The surgical procedure was performed by a multidisciplinary team and the patient received the antibiotic regimen according to the antibiogram, with hospital discharge after 39 days of hospitalization. DISCUSSION: Treatment of osteomyelitis requires the combination of antimicrobial therapy and surgery. Despite surgical and chemotherapeutic advances, it is a difficult condition to treat and there is no universally accepted protocol for treatment. CONCLUSION: Surgical treatment was essential for stabilization of the condition. Due to the complexity of this type of infection in the craniofacial region, planning and execution must be carried out through a multidisciplinary team.
