Necrotizing Fasciitis In The Head And Neck Region-Three Case Reports And A Review Of The Literature

Necrotizing fasciitis (NF) is a life-threatening, usually bacterial, soft tissue infection that rarely affects the head and neck region. Rapid progression and systemic illness are typical for the disease and complicate diagnosis. Immediate surgical and antimicrobial therapy is required. Three cases of cervicofacial NF are presented in this case report. All patients showed a rapidly progressing, painful swelling and redness in the cervicofacial region. After diagnosing NF based on clinical symptoms, laboratory parameters, and CT, the patients were treated with systemic antibiotics and multiple extensive debridements. Two of the three patients died within 48 h from systemic illness with septic organ failure; one patient was discharged after intensive care treatment and reconstruction of the tissue defects caused by debridement. NF is a fast-developing soft tissue infection associated with high mortality and morbidity, and is often recognized too late. Diagnosis is based on clinical signs such as progressive diffuse swelling, pain, erythema, and early systemic illness. Laboratory parameters (Laboratory Risk Indicator for Necrotizing Fasciitis [LRINEC] score) and imaging via CT or MRT are helpful. CT/MRT images can show soft tissue swelling with pathognomonic gas formation. Immediate surgical debridement and antimicrobial therapy are critical for survival. Intravenously administered immunoglobulins and hyperbaric pressure therapy should only be used as supplementary treatments.
