Objective: Assess epidemiological data and clinical predictors of mediastinitis in deep neck infections (DNI) submitted to surgery.Study Design: Retrospective observational
Methods: Data analysis of every DNI patient submitted to surgery from January 2015 to December 2021 in the Otorhinolaryngology department of a tertiary hospital center.
Results: A total of 165 patients with a mean age of presentation of 48,5 years were included. The most frequent etiology was odontogenic infection (51,5%) and the most involved cervical space was the submandibular space (60,6%). Furthermore, the most isolated bacteria in patients with and without mediastinitis was Streptococcus spp. Progression to mediastinitis occurred in 20 (12,1%) patients. In a multivariate analysis, a bilateral DNI location (p=0,015) and a higher neutrophil to lymphocyte ratio (NLR) (0,037) were associated with progression to mediastinitis.
Conclusion: The presence of a bilateral DNI and NLR seem to be the most important clinical predictors of mediastinitis.
