Necrotizing fasciitis of the head and neck in era of COVID-19: a single-institution experience

Abstract

ObjectivesNecrotizing fasciitis (NF) of the head and neck is a critical condition, known for its severe impact and high mortality rates, often linked with diabetes, odontogenic infections, and immunosuppression. Observations from the University of Ottawa's Department of Otolaryngology – Head and Neck Surgery indicate an increase in NF cases since the COVID-19 pandemic began, suggesting a possible association between COVID-19 and NF. This study aims to assess the incidence of NF since the pandemic's onset and explore its association with COVID-19. DesignConducted as a single-center retrospective review from January 1, 2015 to April 7, 2023, this study included patients aged over 18 years with histopathologic confirmation of NF, analyzing clinical risk factors, treatment, and outcomes. Patients were divided into pre- and post–COVID-19 groups for comparison. ResultsOf 16 patients, 68.7% were in the post–COVID-19 group, with a notable increase in 2022. The most common risk factors were diabetes mellitus (43.8%) and history of odontogenic infection or extraction (31.3%). Only one patient (6.3%) presented with concomitant COVID-19 infection and NF. All patients underwent treatment with serial surgical debridement and intravenous antibiotics with mortality rates rising to 12.5% after the pandemic. ConclusionsOur study demonstrates an increased incidence of NF cases in our institution after the COVID-19 pandemic.
