摘　　要：目的:比较替牙期不同垂直骨面型儿童上气道形态和舌骨位置的差异,为临床诊疗和颅面部生长发育的研究提供一定的参考依据。方法:采用计算机辅助X线头影测量技术,对120名替牙期不同垂直骨面型儿童的X线头颅定位侧位片进行测量研究,比较不同性别,不同垂直骨面型组间上气道矢状径和舌骨位置的差异。结果:上气道矢状径:女性大于男性,但除低角组PNS-Ad2、PNS-UPW、SPP-SPPW、U-MPW外无统计学差异;不同垂直骨面型组间存在统计学差异,高角组<均角组<低角组。舌骨位置:男性比女性偏前下;高、均、低角组间舌骨垂直向位置无显著差异,水平方向上高角、均角、低角组舌骨位置逐渐前移。结论:替牙期不同垂直骨面型儿童上气道形态,舌骨位置存在差异。Objective： To study the difference of upper airway form and hyoid position of the children with different vertical facial types in mixed dentition. Methods： Cephalograms of 120 children with different vertical facial types in mixed dentition were retrospectively investigated by computerized cephalometric analysis. Upper airway depths and hyoid position were measured, and differences were compared between male and female, and compared among different vertical facial type groups. Results： The sagittal depth of upper airway in female was larger than in male, but there was no statistical difference except PNS - Ad2, PNS - UPW, SPP - SPPW, U - MPW in low angle group. Significant difference was found among differem vertical facial types, the sagittal depth of upper airway in high angle group was smaller than that in average angle group and low angle group. There had statistical difference in hyoid position between genders. Hyoid of male was positioned more anterior - inferiorly than that of female. In vertical position of hyoid, there was no significant difference among different vertical facial type groups. But in horizontal, the hyoid was more forward in low angle group and more backward in high angle group. Conclusion： In mixed dentition, there had statistical differences in upper airway form and hyoid position in children with different vertical facial types.
