title: Craniocervical necrotizing fasciitis: critical factors in management.
abstract: Necrotizing fasciitis involving the head and neck is rare. The authors describe two such patients treated at their institution and analyse 39 cases reported in the literature. This entity may be divided into two groups based on the site of origin of the infection: group 1 (13 cases) infections, originating in the scalp and eyelids, mostly secondary to trauma, do not progress rapidly, respond well to medical and operative measures and result in minimal permanent disability. These infections usually are caused by hemolytic streptococci and Staphylococcus aureus. Group 2 (28 cases) infections, originating in the face or neck and mostly complications of dental and pharyngeal sepsis, progress rapidly to adjoining sites including the chest wall and mediastinum. These infections are caused by a wide variety of microorganisms including anaerobes; fatal complications are frequent and the death rate is high (32%). Early and very aggressive débridement and drainage are mandatory and should be repeated if warranted.
