Clinical classification of cervical necrotizing fasciitis

Abstract

Purpose

Necrotizing fasciitis of the craniofacial region is a rare and potentially life-threatening bacterial infectious disease. Odontogenic infections primarily spread along facial fascia and subcutaneous tissues, resulting in upper chest skin or thoracic necrosis. The purpose of this clinical classification was to demonstrate clinically important guidelines for early diagnosis and prompt management of CNF.

Methods

Although the incidence of cervical necrotizing fasciitis (CNF) is very rare in many developed countries, prompt management with appropriate initial diagnosis is essential, especially in tropical low-economic rural regions of African countries. Over the last 12 years, our charitable team in West Africa made clinical classifications of CNF according to onset time and spreading pattern to thoracic extension.

Results

CNF patients could be divided into two primary types, limited to neck type and extended to upper chest type. We also further categorized from each type into three different groups according to the CNF onset and clinical characteristics, including acute type with hematogenous spread within 2 weeks, subacute type with suppuration over 2 to 4 weeks, chronic type without suppuration over 4 weeks, multiple type with partial skin necrosis, island type with necrotic skin coverage, and broad type with whole skin necrosis.

Conclusions

These classifications will help decrease the mortality rate in severely infected patients.
