The effect of nasal septal deviation on maxillary sinus volume in patients undergoing septoplasty surgery

Background: In this sudy, we aimed to determine the association between nasal septal deviation and maxillary sinus volume in patients undergoing septoplasty. Materials and Methods: 164 paranasal sinus computed tomography (PNS CT) of the patients(80 female, 84 male) undergoing septoplasty surgery were retrospective evaluated between September 2022 and September 2023. Bilateral maxillary sinuses volüme (MSV) and septal deviation angle(SDA) were calculated using the computed program. SDA was divided into right and left, also was described as mild, moderate, or severe. Results: The mean of right MSV was measured as 14.34 ± 3.91 (7.45-23) and the mean of left MSV was 15.11 ± 4.29 (6.34-24.3). The average SDA of all patients was 15.51 ± 5.22 (6.7-34). The difference between right and left MSV was measured lower in patients with mild septal deviation than in patients with moderate or severe septal deviation (p=0.016, p=0.024, respectively). In the evaluation made according to MSV, the difference values between ipsilateral MSV, contralateral MSV, total MSV and right-left MSV according to the side of septal deviation were found to be higher in men than in women (p=0.011, p=0.001, p=0.004, p
