【摘要】 目的比较研究Ⅰ类与Ⅱ类矢状骨面型成年女性上气道形态和舌骨位置的差异,探讨颅面形态与上气道及周围结构的关系。方法选取成年女性,垂直向平均型,矢状向Ⅰ类与Ⅱ类矢状骨面型者各25例的头颅侧位定位片进行上气道矢状径及舌骨位置的测量并分析比较其差异。结果上气道矢状径均Ⅰ类矢状骨面型组大于Ⅱ类矢状骨面型组,在鼻咽段、腭咽段、喉咽段均有测量指标显示差异有统计学意义(P<0.05);舌骨的位置在垂直向两组间差异无统计学意义(P>0.05),水平方向上,Ⅱ类组舌骨位置较Ⅰ类组后位(P<0.05)。结论Ⅰ类与Ⅱ类矢状骨面型成年女性的上气道形态和舌骨位置存在一定的的差异,矢状骨面型对成年女性的上气道形态和舌骨位置有影响。更多还原

【Abstract】 Objective To analyze the difference of upper airway form and hyoid position between classⅠand classⅡsagittal facial type in adult female and investigate the relationship between craniofacial structures and upper airway form.Methods Cephalograms of 50 female adults with classⅠor classⅡsagittal facial type and average vertical facial type were collected and divided into two groups according to sagittal facial type.Each group were 25 cases.All the cephalograms were measured in upper airway depths and hyoid position and the differences were compared between two groups.Results All the measurements of upper airway depths of classⅠsagittal facial type group were larger than that of class Ⅱ sagittal facial type group and there were statistical differences in some depths of nasopharynx,high oropharynx and laryngopharynx(P<0.05).There was no statistical difference in hyoid vertical position of two groups(P>0.05),but the hyoid position was more backward in class Ⅱ group than in class Ⅰ group in sagittal position(P<0.05).Conclusion There were some differences in upper airway form and hyoid position between classⅠand classⅡsagittal facial types in adult females,so craniofacial structures had some effects on the upper airway form.更多还原
