Background/Aim: Crista galli (CG) is an essential anatomical formation located in the midline on the cribriform plate. In the presence of pneumatized CG (PCG) variations, changes will occur in the anatomy of the anterior skull base. Anterior ethmoidal artery (AEA) crosses the medial wall of the orbit and progresses intraethmoidally; in case it is damaged during endoscopic procedures, it may cause severe epistaxis or intraorbital hematoma. This study aims to examine the CG morphometric features in the Turkish population and to investigate the changes in the distance of the AEA from the nasion and sphenoidal sinus (SS) according to CG morphometry. Materials and Methods: In the study, computerized tomography images of 200 cases were used, CG height-in the coronal plane, PCG ratio, and the distances of the AEA from the nasion line to the anterior wall of the SS were measured in the horizontal plane. In the presence of PCG, the changes in AEA according to their distance from the mentioned formations were examined. Results: The mean CG height was 12.8 +/- 2.4 mm; partial or total pneumatization was observed in 31.5% of the cases. The average distance from the anterior border of the AEA to the Nasion during its intraethmoidal course was 28.3 +/- 3.6 mm, with males having a greater distance than females. Additionally, the average distance to the anterior wall of SS was 17.5 +/- 2.9 mm. Conclusion: This study determined that the distance of the AEA to the nasion was greater in cases with PCG than in cases without pneumatization on both sides.
