Crista Galli Morphometry and Morphology in Sagittal Skeletal Malocclusions: A Retrospective Cross-Sectional Study

Objective: This study aimed that examine the relationship between crista galli morphometry and morphology in different types of sagittal skeletal malocclusion. Materials and Methods: A total of 45 individuals included in the study were examined by dividing them into three subgroups Class I, Class II, and Class III, which included an equal number of samples according to the ANB°. In this study, different morphologies (teardrop, tubular, ossified) and morphometric (length, width, height) measurements of the crista galli were analyzed in adult patients with different sagittal malocclusions. Results: When linear measurements of the crista galli were evaluated, no difference was found between skeletal malocclusion classes in terms of width and height. On the other hand, while the crista galli length is significantly larger in Class I individuals (13.131.93 mm) than in Class III individuals (11.561.26 mm), it is of similar size in Class II individuals (11.672.28 mm). There is no significant relationship between crista galli morphology, Keros classification and crista galli pneumatization and skeletal malocclusion groups. Conclusion: The anteroposterior crista galli length of skeletal class II and III individuals is less than that of skeletal class I individuals. Crista galli morphology does not differ according to sagittal skeletal malocclusions.
