Materials and Methods: This was a retrospective cross-sectional study conducted using patient records from the institution. Institutional Ethical Committee approval was obtained prior to the study. A total of 60 subjects were divided into three groups and studied. Hyoid triangle analysis by Bibby and Preston was carried out to determine the position of the hyoid bone. All radiographs were traced by a single operator and they were retraced to check for measurement error. Results: Student's t-tests and Mann-Whitney U-test were used to find out whether any sexual dimorphism exists. The horizontal distance from the hyoid bone to the retrognathion was found to be significantly larger in males than in females. The hyoid bone is positioned at a lower level in class I and II in males than in females. Also, it was observed that the hyoid angle was significantly greater in males than in females in class II group. Conclusion: Sexual dimorphism was observed in the sample studied. ER -
