RT Journal Article T1 Survival rate of odontogenic descending necrotizing mediastinitis. Our experience in last 5 years A1 Sada Urmeneta, Ángela A1 Agea Martínez, Marc A1 Monteserín Martínez, Eduardo A1 Antúnez Conde, Raúl A1 Gascón Alonso, Dafne A1 Arenas de Frutos, Gema A1 Navarro Cuéllar, Carlos A1 Navarro Cuéllar, Ignacio AB BackgroundDescending necrotising mediastinitis is one of the most lethal and least frequent forms of mediastinitis. It is a life-threatening infection most frequently originating from an oropharyngeal or odontogenic infection.Material and MethodsA retrospective study of 6 patients diagnosed and treated for descending necrotising mediastinitis between 2015 and 2020 is reported.ResultsAll patients were male, mean age of 34.83 years; 66% were smokers. 83% had an orocervical infection and 34% had initial mediastinal spread. All patients were treated initially with empirical broad-spectrum antibiotics and surgical drainage, with subsequent admission to the Intensive Care Unit; only one of them required tracheostomy. The mean hospital stay was 27.37 days. After a mean follow-up of 6 months, 100% of the cases had a complete recovery.ConclusionsEarly diagnosis and surgical treatment combined with improved life-support treatment in intensive care units and broad-spectrum antibiotic therapy leads to a decrease in associated mortality.
