摘要： 目的:比较恒牙期单侧完全性唇腭裂患者正畸治疗前后舌骨位置的变化,探讨正畸治疗对恒牙期单侧完全性唇腭裂患者舌骨位置的影响。方法:选择恒牙期单侧完全性唇腭裂前牙反患者20名,其中男性15名,女性5名,平均年龄18.60±4.72周岁。测量所有患者正畸治疗前后头颅侧位片上反映舌骨位置的6项指标,用配对t检验比较治疗前后舌骨位置的变化。结果：正畸治疗后H-PTRper(mm)，H-Sper (mm) 明显增大（P＜0.05）,差异有统计学意。 其他指标差异无统计学意义。结论：恒牙期唇腭裂患者在接受正畸治疗后,舌骨矢状向后移明显，但垂直向变化和旋转角度变化并不显著。

Abstract: Objective：To compare the hyoid bone position in patients with the Unilateral Cleft Lip and Palate(UCLP) following the orthodontic treatment. Methods: 20 UCLP patients with crossbite of anterior teeth were included in this study. There were 15 male and 5 female patients,with average age 18.60±4.72 years. Lateral cephalogram were taken for each patient before and after treatment. 6 measurements were carried out to find the changes of the hyoid. The paired t test was used to evaluate the changes of the hyoid bond. Result: H-PTRper(mm) and H-Sper(mm) increased significantly（P＜0.05）after the orthodontic treatment. Other measurements had no significant changed after treatment. Conclusion: The anteroposterior position of the hyoid bone was significantly backward after orthodontic treatment There were no significant changes of the vertical position and the axial inclination of the hyoid
