RESUMO
Soft tissue infections are characterized by acute inflammation, diffuse edema, and suppuration, and are often associated with symptoms such as malaise, fever, tachycardia, and chills. Necrotizing fasciitis is a destructive bacterial infection affecting subcutaneous tissue and superficial fascia and is associated with high rates of mortality. It usually involves the abdomen and extremities, but it also can occur in the head and neck. Early diagnosis is critical and the most commonly accepted treatment includes radical surgical intervention and administration of broad-spectrum antibiotics. This article reports and discusses the case of a patient with odontogenic cervicofacial necrotizing fasciitis, and emphasizes the importance of early and effective treatment.
