Computed tomography analysis of fascial space involvement demonstrates correlations with laboratory tests, length of hospital stays and admission to the intensive care unit in odontogenic infections

Abstract Objectives: Odontogenic infections are frequent and can spread, leading to complications such as sepsis and the need for admission to an Intensive Care Unit (ICU). The purpose of this study was to perform a computed tomography analysis of the fascial space involvement and correlate with personal data, laboratory tests, length of hospital stays and admission to the ICU in patients with odontogenic infections who required hospitalization. Methods: Patients with odontogenic infections admitted between June 2017 and May 2018 were prospectively evaluated. The fascial spaces involved were studied using computed tomography with contrast. The possible correlations of tomographic findings with comorbidities, nutritional status, the causative tooth, laboratory tests, length of hospital stays and admission to the ICU were analyzed. Results: We identified 66 cases of odontogenic infections which were admitted in the period analyzed. The involvement of primary spaces (86.7%) predominated, followed by secondary ones (8.7%), and cervical (4.6%). The most frequently involved fascial spaces were submandibular (27.1%), buccal (20.8%), sublingual (18.3%), submental (16.7%), and others (17.1%). There were significant differences between laboratory tests (p
