Massive necrotizing infections of the neck.

Necrotizing fascitis of the head and neck is a rare condition with only 7 cases recorded in the literature. Two cases are presented in which there was massive necrosis of the soft tissues of the neck with extension into the mediastinum. The offending organisms were a mixed bacterial flora which produced gangrene accompanied by subcutaneous emphysema. Both patients were successfully treated with a regimen of intravenous antibiotics, fasciotomy, radical debridement, and hyperbaric oxygenation (1 case). The clinical features, bacteriology, and treatment of necrotizing faciities are reviewed.
