It is unclear if septal deviation at the insertion points to the nasal cavity is associated with the overall septal deviation. This study aimed to assess septal deviation at the cribriform plate (CP) and maxillary crest (MC) using CT scans and to see if there was any correlation with overall septal deviation. MethodsAll consecutive CT sinus scans between January 2020 and December 2021 were retrospectively reviewed.Patients were excluded if they had a history of head, nasal or facial trauma, or any previous nasal surgical procedure. Angles between the septum and MC and the septum and CP as well as maximal angle of septal deviation (MSD) were measured. ResultsA total of 70 scans were included in the nal analysis. The mean MSD was 8.14°. The mean septal deviation was 0.89° at the CP and 2.02° at the MC. The correlation coe cient between the deviation at the CP and MSD was 0.025 and between the deviation at the MC and MSD was 0.321. ConclusionOur data reveal a positive correlation between septal deviation at the oor of the nose and overall septal deviation; this was not observed at the septal deviation at the roof. This could be explained due to the inherent tilt in the cribriform plate or by earlier ossi cation and xation of the septum during its development at its insertion to the roof, thereby allowing further growth and potential for deviation of the lower part of the septum and its insertion to the oor.

“…They opposed our findings, however, on the grounds that there were no discernible differences in LNW among the comparison groups. Furthermore, they illustrated that an SDD of 2.43 mm or greater, an SDD/LNW of 0.25 or greater, or an SDA of 7.6° or greater may signify a clinically significant deflection that necessitates thought of septoplasty for access during sinus surgery [4].…”

Background High anterior septal deviation is an underreported anatomical variant that can influence the decision to conduct septoplasty throughout FESS and to facilitate after-surgery care. Objective To assess the prevalence and clinical implications of HASD on sinus access. Methods This retrospective, cross-sectional research was performed on patients with symptoms of DNS and CRS who were prepared for FESS. CT scan PNS coronal sections have been requested with three measurements: distance to the septum (SDD), distance to lateral nasal wall (LNW), and septal deviation angle (SDA). Results One-hundred fifty-seven patients were included; 73 of them received septoplasty. There is significant increase in SDD (mm), LNW (mm), SDD/LNW, and SDA (degree) in septoplasty group with significant AUC that predict the need of septoplasty. Characteristic cutoffs were SDD more than or equal 2.55 mm, SDD/LNW more than or equal 0.239, and SDA more than or equal 8.95°. There is significant decrease in polyps and edema in septoplasty group postoperatively compared to preoperative. Conclusion Septoplasty during FESS allows room for endoscopic instrumentation, provides adequate visualization of the surgical field and throughout postoperative care, and can reduce the possibility of failed FESS.

The mean MSD was 8.14°. The mean septal deviation was 0.89° at the CP and 2.02° at the MC. The correlation coefficient between the deviation at the CP and MSD was 0.025 and between the deviation at the MC and MSD was 0.321.Conclusion Our data reveal a positive correlation between septal deviation at the floor of the nose and overall septal deviation; this was not observed at the septal deviation at the roof. This could be explained due to the inherent tilt in the cribriform plate or by earlier ossification and fixation of the septum during its development at its insertion to the roof, thereby allowing further growth and potential for deviation of the lower part of the septum and its insertion to the floor.
