Abstract
Nasal endoscopy and computed tomography (CT) scans are used as diagnostic modalities of paranasal sinus disease. A randomized study was carried over 40 patients diagnosed with chronic rhinosinusitis who undervent a diagnostic nasal endoscopy and a CT scan. The purpose of the study was to demonstrate the effectiveness and limitations of CT and endoscopy in assessment of CRS. In this study we observed that endoscopy was superior for assessment of localized disease like polyp, pathological secretion, presence of accessory maxillary ostia and condition of mucosa. CT scan gave a better idea of the condition of paranasal sinuses, the osteomeatal complex and various anatomical variations including concha bullosa, paradoxical middle turbinate and deviated nasal septum. Keywords: Tomography, Endoscopy.
