Background: Computed tomography (CT) scan is a diagnostic tool for chronic rhinosinusitis (CRS). This study was attempted to correlate preoperative CT scan and endoscopic findings in patients with CRS. Aims: This study aimed to correlate CT scan and nasal endoscopic findings in the assessment of patients with CRS. Study Design: This is a hospital-based study. Subjects and Methods: One-year observational study was conducted in the Department of Otorhinolaryngology, KLES Dr. Prabhakar Kore Hospital and Medical Research Centre, Belgaum. Thirty patients meeting 2007 revised criteria for CRS underwent CT scan of paranasal sinus, diagnostic nasal endoscopy, and functional endoscopic sinus surgery. Statistical Analysis: Statistical analysis was performed by Kappa's measure of agreement and P value. Results: Correlation between CT scan and endoscopy was good in cases of anterior ethmoids (right, k = 0.867; P< 0.02, left, k = 0.525, P = 0.003), concha bullosa (right, k = 0.68; P< 0.001, left, k = 0.520; P = 0.003), and maxillary sinus (right, k = 0.786; P< 0.001, left, k = 0.636; P< 0.001). Correlation was acceptable for frontal sinus (right, k = 0.488; P = 0.007, left, k = 0.493; P< 0.05), mucosal thickening (k = 0.525; P = 0.003), polypoidal changes (k = 0.457; P = 0.012), posterior ethmoids (right, k = 0.590; P = 0.04; left, k = 0.432, P = 0.015), and sphenoid sinus (right, k = 0.492; P = 0.006, left, k = 0.444; P = 0.013). Correlation was poor in cases of paradoxical middle turbinate (k = 0.384; P = 0.051) and osteomeatal complex (OMC) occlusion (right, k = 0.416; P = 0.011, left, k = 0.367; P = 0.020). Conclusions: Endoscopy was superior to CT scan in localizing pathologies such as polyp, edema, and discharge, whereas CT scan was useful for OMC assessment to visualize paranasal sinus and anatomical variations.
