Introduction
Due to the diverse variation of the ethmoid bone, we evaluated the roof using the Keros and Yenigun classifications, stratifying results by gender and side to determine difference.
Materials and methods
Paranasal sinus high‐resolution computed tomography were included from 2012 to 2017, excluding all those with pathologies that alter the anatomy of the region in study. The depth of the cribriform plate in a coronal view and the anterior‐posterior length in a cross section were measured for classification and analysis.
Results
A total of 120 high resolution CT were included. The Keros Type II and Yenigun type I were the most frequent, with only statistical difference between men and women in Yenigun types I and II (p = 0.010 and p = 0.049, respectively). Statistical difference was observed in anterior‐posterior means in the comparison between both classifications. In both, right and left side for men (p = 0.003 and p = 0.05) and women (p = 0.029 and p = 0.039)
Conclusion
Morphological variability exists in a Mexican population. Bone injury may be more likely in men and vascular injury in women due to their incidence of classification. Gender differences that must be taken into account by the surgeon to avoid such complications.
