摘要

Chronic rhinosinusitis poses a substantial health concern, impacting approximately 5–12% of the overall population (de Loos et al., In J Allergy Clin Immunol 143(3):1207–1214, 2019). For patients with chronic rhinosinusitis, the preferred radiological investigation is a CT scan of the nose and paranasal sinuses (PNS), encompassing both bone and soft tissue windows (Kato, In Allergol Int 64(2):121-130, 2015). There is a lack of data regarding the comparison of pre-operative CT scan and intra-operative findings in patients with chronic rhinosinusitis. Therefore, the present study was undertaken to compare pre-operative CT scan findings with intra-operative findings in patients diagnosed with chronic rhinosinusitis, both with and without polyps. Out of 70 cases, 45 had CRS with polyposis while rest 25 presented with CRS without polyposis. CT PNS showed maximum involvement of maxillary sinus, which correlated with FESS findings and the least involved sinus was sphenoid sinus.
