Objectives: To determine the impact of sinus computed tomography (CT) on treatment decisions by otolaryngologists and to explore the factors leading to choice of surgical treatment for patients suspected of having chronic sinusitis. Design: Prospective cohort study. Setting: A tertiary academic medical center. Patients: Questionnaires were administered to 3 otolaryngologists in a tertiary academic institution regarding diagnosis and treatment decisions in 27 patients suspected of having chronic sinusitis, before and after they reviewed sinus CT scans. Main Outcome Measures: The dichotomous decisions regarding surgical or nonsurgical treatment and the agreement of treatment decisions among surgeons were evaluated. The factors strongly influencing surgeons' treatment decisions regarding patients selected for surgery were also determined. Results: The dichotomous treatment decisions were changed in one third of patients (9 of 27) after the sinus CT scans were reviewed. The agreement of treatment decisions among the 3 surgeons was markedly improved after they reviewed sinus CT scans. The factors favorably influencing surgical treatment were obstruction of the ostiomeatal complex on CT and concordance of CT abnormality with a patient's symptoms. Lund-Mackay stage, symptoms, and corticosteroid or antibiotic use were not significant predictors. Conclusions: Despite the common belief that treatment decisions for chronic sinusitis should be solely based on clinical grounds, with sinus CT providing only anatomic detail before surgery, our study indicates that the decision to perform surgery was altered by CT in a substantial portion of the patients. In our preliminary study, CT increased the tendency to elect surgical treatment by all 3 surgeons.
