Abstract

Objective

We evaluated the olfactory fossa and Keros classification in patients with unilateral mucosal contact points in septal deviation.

Methods

Paranasal sinus computed tomography images of 60 patients with mucosal contact points on the septum were compared with those of the control group (N = 60). The Keros types, septal deviation angles, mucosal contact point angles, olfactory fossa widths and depths, crista galli lengths, widths and pneumatisations, as well as the presence of anatomical variations, were analysed.

Results

The depth of the olfactory fossa contralateral to the mucosal contact point was greater in patients with septal deviation compared to those without (p < 0.05). A significant correlation was found between increased crista galli height and a higher Keros degree on the right side (p < 0.05).

Conclusion

The presence and differences of mucosal contact points should alert surgeons both before and during the surgical procedure, and further studies on this topic are of great importance.
