CT-based study of anatomical variations in chronic rhinosinusitis patients

Abstract

Introduction: Chronic rhinosinusitis (CRS) is frequently associated with anatomical variations that may predispose individuals to impaired sinus drainage and mucosal inflammation. Computed tomography (CT) of the paranasal sinuses provides an essential diagnostic tool for evaluating these variations. Objective: To assess the prevalence and types of anatomical variations in patients with CRS using CT Data. Material and Methods: A retrospective cross-sectional study was conducted on 75 patients diagnosed with CRS. CT scans were evaluated for anatomical variations including concha bullosa, deviated nasal septum, agger nasi cells, Haller cells, Onodi cells, uncinate process variations, and paradoxical middle turbinate. Results: The most frequent variation observed was concha bullosa (64%), followed by deviated nasal septum (61.3%), agger nasi cells (49.3%), and Haller cells (32%). Onodi cells were observed in 21.3% of patients, uncinate process variations in 17.3%, and paradoxical middle turbinate in 12%. Conclusion: Anatomical variations are common in CRS patients and can play a critical role in the pathophysiology of the disease. CT imaging is vital in identifying these variations, which can guide appropriate surgical planning.
