RESUMO
PURPOSE: We evaluated a method to distinguish group A (abscess) from group B (cellulitis, pharyngitis, tonsillitis, epiglottis) through clinical variables in patients with a deep neck infection. METHODS: This was a retrospective chart review study consisting of the evaluation of CT scans or surgical diagnoses on adult patients (18 or more years of age). CT scans were reviewed by a radiologist. We evaluated several clinical variables in order to distinguish group A from group B. We also evaluated the ability of these clinical variables to distinguish group A from group B by a receiver operating characteristic curve. RESULTS: Sixty-three patients were enrolled in this study. Several clinical variables (swelling, odynophagia, tenderness, trismus, age>50years) differed between group A and group B. A AUC which was obtained by adding the number of variables (swelling, odynophagia, tenderness, trismus, age>50years) was 0.87 (p50, swelling, odynophagia, tenderness, trismus) were able to distinguish group A from group B.
