Evaluation of the Hyoid Bone Position Based on the Hyoid Triangle in Patients With Different Skeletal Patterns: A Lateral Cephalometry Cross‐Sectional Study

Background and Aims: We aimed to compare the hyoid bone triangle among individuals with Class I, II, and III skeletal patterns, considering different facial growth patterns. Methods: A total of 296 patients were included in the study. Skeletal patterns were classified using the A Point-Nasion-B Point (ANB) angle and Wit's appraisal, while the Bjork angle and Jarabak index were employed to categorize facial growth patterns (vertical, horizontal, and normal). Hyoid triangle measurements-based on two facial parameters (C3-H and H-RGn) and one cervical vertebral parameter (C3-RGn)-were compared across skeletal classes and facial growth patterns. Results: = 0.030) compared to Class II. Conclusion: Class II patients tend to have a more posterior hyoid bone position, except in normal growth patterns, where the hyoid position is relatively more anterior. Vertical growth patterns in Class II patients are associated with a lower hyoid bone position.
