摘要
目的:比较不同垂直骨面型成年患者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参考依据。方法:采用计算机辅助X线头影测量技术,对120名不同垂直骨面型成年患者的X线头颅定位侧位片进行测量,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:上气道各段矢状径男性大于女性,但除V-LPW外无统计学差异;不同垂直骨面型组间存在显著差异,高角组<均角组<低角组。舌骨位置存在性别差异,AH-SN,AH-FH男性大于女性(P<0.01),AH-C3男性大于女性(P<0.001),舌骨位置男性比女性偏前下。不同垂直骨面型组间舌骨垂直向位置无显著差异(P>0.05),水平向从高角、均角到低角组AH-O逐渐减小,AH-C3逐渐增大,舌骨位置在水平向逐渐前移。结论:不同垂直骨面型成年患者上气道形态、舌骨位置存在差异,这可能与不同垂直骨面型下颌骨的旋转方式有关。
Objective：To study the difference of upper airway form and hyoid position of the adults with different vertical facial types. Methods：Cephalograms of 120 adults with different vertical facial types were retrospectively investigated by computerized cephalometric analysis. Upper airway depths and hyoid position were measured, and differences were compared between male and female, also compared among different vertical facial type groups. Results ：The sagittal depth of upper airway in male was larger than that in female, but there was no statistical difference except V-LPW. Among different vertical facial types, the sagittal depths of upper airway in high angle group was smaller than that in average angle group and low angle group. There was statistical difference in hyoid position between genders, AH-SN, AH-FH and AH-C3 in male were larger than in female （ P 〈0.01 or P 〈0. 001 ） , it suggested that the hyoid of male was positioned more anterior-inferiorly than that of female. Among different vertical facial type groups, there was no significant difference in vertical position of hyoid. But in horizontal, AH-O decreased and AH-C3 increased from high angle group, average angle group to low angle group, it indicated that the hyoid was more forward in low angle group and more backward in high angle group. Conclusion：In adults with different vertical facial types, there are statistical differences in upper airway form and hyoid position, which might be due to different mandibular rotation.
