A

variety of anatomical variants in the sinonasal region are commonly identfied through sinus CT scans. The variations are potentially linked to chronic rhinosinusitis.

Purpose. To determine the computed tomography validities of nasal cavity and paranasal sinuses in normal anatomical variant and to assess the role of CT in chronic sinusitis.

Materials and methods. A prospective study was conducted at department of radiology in Al-Hilla General Hospital from 26th July 2023 to 29th May 2024. Participants data, including age, sex, effected sinus and CT findings were evaluated. All multidetector computed tomography (MDCT) scan findings were analyzed by experience radiologist.

Results. In this study, 27 patients with chronic sinusitis were enrolled. The mean age of patients was 19.63±8.76 yrs. Among them 20 (66.7%) were male, and 10 (33.3%) were female. The commonest effected sinus was Maxillary sinus in 19 cases (70.4%). Nasal septal deviation (NSD) seen in the most of patients in 21 cases (77.8%). Concha Bullosa (CB) was visualized in 8 cases (44.4%).

Discussion. In this study, the commonest effected sinus was Maxillary sinus in 19 cases (70.4%), sphenoid sinus were 6 cases (22.2%), and ethmoid sinuses in 6 cases (22.2%). NSD seen in the most of patients in 21 cases (77.8%). Uncinate process variation and mucosal thickening of the sinuses seen in one case for each. Mucosal thickening of the sinuses was noticed in seven cases. Concha bullosa was visualized in 8 cases (44.4%). Nasal septal spur reported in 5(27.8%) cases. Inferior turbinate enlargement was visualized in 2 cases (7.4%). Pneumatization lateral sphenoid bone wings and pneumatization of anterior cliniod process of sphenoid bone were seen in one case for each. Nearly, same percent than our findings seen by Dawood mentioned several anatomic variants as NSD (71.7%),  septal spur (34%), septal pneumatization (16.7%), paradoxical turbinate (19%), hypoplastic turbinate (1%), Aggernasi cells (72%), Haller cells (70.7%), Onodi cells (44.7%), elongation of ethmoid Uncinate process (69.7%), pneumatization of ethmoid process (3%), frontal sinus agenesis (hypoplasia) (11.7%), Keros classification [I=31%, II=66.7%, III=2.3%], asymmetry of ethmoidal roofs (43.3%), sphenoidal variants (78.7%), crista galli pneumatization (5.7%), hypoplasia of maxillary sinus (1.3%) and maxillary septum (25%). Also, these data similar to other studies like Kaya et al., Kubota et al., Choby et al., and Han et al. NSD in this study is common, this is similar to Kaya et al., Kaplanoglu et al., Sharma et al. and differ from Reddy et al. and Alsowey et al.

Conclusions. Maxillary sinus is the commonest effected sinus. Nasal septal deviation is the commonest anatomical variants. The mucosal thickening and Concha bullosa variants more visualize in male than female. The effected sinuses of anatomical variants distribution influences by age of patients but not by sex. CT scan more reliable to detection numerous anatomic variants of nasal cavity and PNS.
