Morphometric and Morphological Assessment of Crista Galli in Gender Determination – A CBCT Study

Context: Gender determination using crista galli (CG). Aims: To estimate the morphometric and morphological characters of CG in cone beam computed tomography (CBCT) scans and to evaluate its relation with gender determination. Settings and Design: A Retrospective Study. Methods and Material: In total, 281 (112 males and 169 females) CBCT images were analyzed, and the height, length, and width of CG were calculated. The morphological types according to the position of CG based on the base of the cribriform plate and the shape of the CG were assessed. Pneumatization of CG was investigated. Statistical Analysis Used: ROC curve analysis was used to predict the gender; descriptive analysis and independent student t -test were used to compare mean values of CG morphometric parameters with gender; and the Chi-square test was used to analyze the presence of pneumatization and morphological classification of CG. Results: The most common types of Keros were type II, type III, and type I; the teardrop type was seen more frequently, followed by tubular and ossified types. Pneumatization was present in 4.3% of the patients. The study showed a significant relationship between morphometric measurements and gender, with an accuracy of 60% in gender determination when height was considered and 58% accuracy when the width of CG was considered. The morphological characters of CG showed no significant relationship with gender. Conclusion: The morphometric and morphological characters of CG can be evaluated using CBCT images, and these characters can be used in gender determination.
