Facial necrotizing fasciitis from an odontogenic infection

Necrotizing fasciitis (NF) is defined as rapidly progressive necrosis of subcutaneous fat and fascia. It is a rare but life-threatening infection characterized by a progressive, usually rapid, necrotizing process of the subcutaneous tissues and fascial planes. The condition is commonly described in the extremities, abdominal wall, and perineum but rarely seen in the head and neck. The diagnosis of NF depends mainly on clinical features, which are not always observable, so that the disease is often diagnosed late in its course, resulting in high mortality. Broad-spectrum antibiotics, aggressive surgical treatment and supportive therapy are the most widely accepted modalities of successful treatment. We describe a case of necrotizing fasciitis of the head and neck, arising from odontogenic origin.
