摘　　要：目的 :对比骨性安氏Ⅰ类及骨性安氏Ⅲ类早期恒牙患者的舌骨位置。方法 :选取骨性安氏Ⅰ类及骨性安氏Ⅲ类错患者 ,每组 30例 ,对其头颅侧位片上舌骨的位置进行比较分析。结果 :与安氏Ⅰ类错者相比 ,安氏Ⅲ类错者的舌骨位置更靠前 ,且与下颌平面呈顺时针方向旋转关系。结论 :舌骨的位置变化与下颌骨的位置改变有关。Objective:To analysis hyoid position in subjects with Class Ⅰ and Class Ⅲ malocclusions.Methods:Sixty patients (30 cases with Class Ⅰ,30 cases with Class Ⅲ) were selected according to skeletal relationships.Cephalometric analysis was made for the assessment of the hyoid position in relation to skeletal structures.Results:Compared with skeletal Class Ⅰ patients,Skeletal Class Ⅲ ones showed a more anterior position of hyoid bone and also a reverse inclination in relation to mandibular bone.Conclusion:This study showed that changes in hyoid bone position were related to changes in mandibular position.
