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.
Insights
Necrotizing fasciitis of the head and neck is rare, often presenting in two distinct groups based on infection origin. Early, aggressive surgical intervention is crucial for survival in severe cases.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Plastic Surgery
Background:
- Necrotizing fasciitis (NF) of the head and neck is an uncommon but severe soft tissue infection.
- This condition requires prompt diagnosis and aggressive management to prevent mortality and morbidity.
Observation:
- The study analyzed 39 cases of head and neck NF, categorizing them into two groups based on the infection's site of origin.
- Group 1 (scalp/eyelids) infections, often trauma-related, were less aggressive and responded well to treatment.
- Group 2 (face/neck) infections, frequently linked to dental or pharyngeal sepsis, showed rapid progression and higher mortality.
Findings:
- Group 1 infections, typically caused by hemolytic streptococci and Staphylococcus aureus, had better outcomes.
- Group 2 infections involved diverse microorganisms, including anaerobes, and were associated with rapid spread to the chest and mediastinum.
- Group 2 NF had a significant mortality rate of 32%.
Implications:
- Early and aggressive surgical débridement and drainage are essential for managing head and neck NF.
- Prompt recognition and intervention are critical, especially for Group 2 infections, to improve patient outcomes.
- Further research into optimal antimicrobial strategies for polymicrobial infections is warranted.
