The Effect of Deviated Nasal Septum on Sphenoid Sinus Exposure on Endoscopic Endonasal Transsphenoid Approach

Abstract

• Purpose: Endoscopic Endonasal Trans-Sphenoid Approach (EETA) to sphenoid sinus remains a valuable procedure for both neurosurgeon and ENT surgeon. Structural variants in the form of deviated septum, and concha bullosa were commonly found. This study was to evaluate the effect of deviated nasal septum on sphenoid sinus exposure and the correlation between the site and angle of deviation of nasal septum, the nasal width with the success of approaching the sphenoid sinus ostium. • Methods: The study included 30 patients with sphenoid or para-sphenoid lesions and septal deviation. All patients underwent an Endoscopic Endonasal Trans-Sphenoid Approach. Preoperative CT was used to calculate the angle of septum deviation and nasal width. • Results: The mean deviation angle of the participants was 13.77±5.16 and the mean width of the participants was 1.44±0.30. Intervention was done in one third of cases. A significant difference was found between the intervention and non-intervention groups, with a higher median deviation angle in the intervention group (20 degrees). No significant difference was found between the two groups regarding nasal cavity width. Our results shows that the deviation angle is a better predictor than width of the nasal cavity. Regarding deviation angle the cutoff angle at 11.5 is a good discriminating with p value <0.001. • Conclusion: Septal deviations with an angle greater than 20 degrees significantly affect the visibility of the operative bed, necessitating surgical intervention to improve visibility. Our study concludes that the deviation angle is a better predictor of surgical outcomes than the width of the nasal cavity
