Abstract: Objective:To investigate the upper airway shape and hyoid position in the early permanent dentition in Uygurs and Hans. Methods: Cephalometry was carried on patients with early permanent dentition. The jaw, hyoid bone, and upper airway were traced and measured for statistical data processing. Results: In the upper airway measurements, no difference was found between Uygur and Han. With regard to vertical direction of hyoid position, no difference was found. However, in the horizontal direction, H-CVP in Han was significantly larger than that in Uygur. Conclusion: There was no significant difference in the upper airway shape between the Uygur and Han patients with early skeletal class I malocclusion, however, the difference in the horizontal direction of hyoid was significant.
