Necrotizing fasciitis of the head and neck: an analysis of 47 cases.

Necrotizing fasciitis is an overwhelming infection common to the perineum, abdominal wall, and extremities. It is a surgical emergency related to a high mortality rate that is more often seen in elderly and immunocompromised patients. Necrotizing fasciitis occurs uncommonly in the head and neck region. Over a 12-year period, 47 cases of necrotizing fasciitis of the head and neck region were collected at this hospital. The demographics, predisposing factors, clinical presentation and courses, management, complications, and outcomes were analyzed. The cases were divided into two groups: survivors and nonsurvivors. Statistical comparisons were made of the parameters age, gender, smoking or drinking habit, underlying medical problems, laboratory data, and treatments used. Forty-two patients (89.4 percent) had associated systemic disease; most of these patients had diabetes (72.3 percent). The clinical manifestations are nonspecific but are often typical for diagnosis. The necessity of computed tomographic scans is not conclusive in this study. Presentation of septic shock (p = 0.004) and association with underlying malignancy (p = 0.03) were the only statistically significant factors that led to a poor prognosis. The cornerstones of proper management include early diagnosis, aggressive surgical debridement, broad-spectrum antibiotics, and intensive supportive care.
