Objectives Descending necrotizing mediastinitis (DNM) developing after deep neck infection (DNI) is a potentially lethal disease of the mediastinum with a mortality rate as high as 40% prior to the 1990s. No standard treatment protocol is available. Here, we present the outcomes of our multidisciplinary approaches for treating DNM originating from a DNI. Methods Between June 2016 and July 2021, there were 390 patients with DNIs admitting to our tertiary hospital. A total 21 patients with DNIs complicated with DNM were enrolled. The multidisciplinary approaches included establishment of airway security, appropriate surgery and antibiotics, extracorporeal membrane oxygenation, and intensive care unit management. The clinical variables were analyzed. Results Two patients died and 19 survived (mortality 9.5%). The patients who died had a higher mean C-reactive protein (CRP) level than did those who survived (420.0 ± 110.3 vs 221.8 ± 100.6 mg/L) (P = .038). The most common pathogens were Streptococcus constellatus and Streptococcus anginosus. From 2001 to 2021, the average mortality rate of studies enrolling more than 10 patients was 16.1%. Conclusion Multidisciplinary approaches, early comprehensive medical treatment, and co-ordination among departments significantly reduce mortality. Patients with severe inflammation and high CRP levels require intensive and aggressive interventions.
