Anatomical variations of nasal structures in chronic rhinosinusitis as detected by Computed Tomography scan

Abstract

Chronic rhinosinusitis is an inflammatory condition of the mucosa of the nose and paranasal sinuses persisting for more than 12 weeks without complete resolution and of multifactorial etiology. The relation between anatomical variations and sinusitis is not clear till now. Some studies showed statistically significant association between common anatomical variations and the presence of sinusitis while in other studies no statistically significant relationship was found. Our study included 88 cases which were divided into two groups: The first group was the case group including patients who had chronic rhinosinusitis as detected by CT of paranasal sinuses (44 patients). The second group was control group including patients who underwent paranasal CT scan and no chronic rhinosinusitis was detected (44 patients) to detect the relation between the following anatomical variations and chronic rhinosinusitis: 1. Concha bullosa. 2. Uncinate variations. 3. Nasal septal variations.
