ABSTRACT

The asymmetry of the ethmoid roof is a well-known anatomic variation; it is important to be aware of it in order to avoid complications during endonasal sinus surgery. The goal of the study was to determine the asymmetric distribution of the ethmoid roof and see if the findings could have a gender-based correlation. A retrospective, comparative and descriptive study was made on direct coronal paranasal sinus computed tomography scans of patients of both genders. The height and contour of the fovea ethmoidalis were examined for symmetry between the right and left sides, as well as the Keros type in each computed tomography scan. The study included a total of 100 patients, 49 men and 51 women. Asymmetry in the height of the fovea ethmoidalis was determined in 97 patients, 39 were lower on the left side (36 women and 22 men) and 58 had a lower right side (36 women and 22 men). The asymmetry was also determined in the lateral lamina in 97 patients: left side was longer in 39 patients (24 women and 15 men), right side was longer in 61 patients (28 women and 33 men). Measurements, with asymmetrical results. This study can help future investigation programs to establish the risk of intracranial penetration based on the difference in height and length of the ethmoid roof.
