Abstract

Introduction: The crista galli, a prominent bony ridge located in the ethmoid bone, has garnered attention as a potential anatomical landmark for various medical and surgical procedures. Cone Beam Computed Tomography (CBCT) has emerged as a reliable imaging modality for detailed craniofacial analysis.
Aim: The aim of this study is to measure the width, length, and height of the crista galli and analyze any potential variations in these dimensions using CBCT images. Additionally, the study aims to investigate the morphological variations of the crista galli and assess the presence of pneumatization.
Material and Methods: A retrospective analysis was conducted on CBCT images of 558 patients using IBM SPSS Statistics 18 software. Morphometric measurements, including width, length, and height, were recorded. The crista galli was morphologically classified into three types, and the presence of pneumatization was investigated. Statistical analysis was performed to compare the findings between genders, and ROC (Receiver Operating Characteristic) analysis was conducted to determine the discriminative performance of the data.
Results: Of the 558 patients included in the study, 228 (51.6%) were female and 270 (48.4%) were male, with a mean age of 46.92±16.81 years. The mean width value in all patients was 3.34±1.28, the length value was 11.5±2.33, and the height value was 13.25±2.67.The distribution of morphological types significantly differed between genders (p<0.001). Tear type was more prevalent in women (71.5%) while the tubular type was more common in males (34.4%). Ossifying type was also more frequent in males (10.7%) .The most common morphological type among all patients was tear type(63.4%). The presence of pneumatization was observed in 7.5% of all patients, with no statistically significant difference between genders (p=0.062).
Conclusions: This study provides a comprehensive morphometric analysis of the crista galli using CBCT images. The findings demonstrate variations in the morphometric analysis of crista galli, as well as significant differences in morphological types between genders. These results contribute to our understanding of the anatomical characteristics of the crista galli and have implications for medical and surgical procedures involving this bony ridge. The findings highlight the importance of individualized assessments and considerations when utilizing the crista galli in clinical practice.
