Acute cervicofacial necrotizing fasciitis: three clinical cases and a review of the current literature.

Cervicofacial necrotizing fasciitis (NF) is a rare condition that can quickly become life-threatening if appropriate treatment is delayed. This condition is observed as a rapidly progressive infection that causes extensive necrosis of the superficial fascia. This report presents a case of cervicofacial NF with microbiological isolation of methicillin-resistant Staphylococcus aureus in a patient with a history of uncontrolled diabetes mellitus following a minor scalp trauma. The article also presents two cases of NF secondary to odontogenic infection. The radiographic finding of the presence of gas locules in the facial planes on the CT scan helped to confirm the diagnosis. Patients were treated with broad-spectrum antibiotic therapy, extensive surgical drainage, debridement, and supportive care. Awareness in the dental community of the signs of NF will facilitate optimal patient management.
