【摘要】 目的:研究恒牙早期青少年不同矢状骨面型上气道宽度及舌骨位置,从而探讨阻塞性睡眠呼吸暂停综合症发病与矢状骨面型的关系。方法:对110名青少年分成3组,分别为Ⅰ、Ⅱ、Ⅲ类骨面型,无鼾症,无腺样体,扁桃体肥大等咽部疾患,进行X线头影测量分析,研究不同矢状骨面型的气道宽度,舌骨位置。结果:通过ANB角进行分组,得出3种矢状骨面型青少年的气道宽度值,舌骨位置值和变异范围,并比较3组间的差异。结论:3组矢状骨面型间腭咽宽度无显著性差异,但舌咽宽度Ⅱ、Ⅰ、Ⅲ类有渐增大趋势,并且Ⅱ类与Ⅲ类比较舌咽宽度有显著性差异,舌骨垂直向位置无明显关系,而矢状位置有显著差异。更多还原

【Abstract】 Objective: The purpose of this study was to investigate various upper airway widths and tongue positions according to different Angle classification in adolescence. Methods: 110 adolescences without snoring, cardiocirculatoy disturbances, tonsil hypertrophy and similar pharynx disturbances were recruited and classified into 3 groups in terms of Angle classification. Lateral cephalometric were taken respectively to compare the difference of upper airway width and tongue position among three groups. Results: The variety of upper airway widths and tongue positions were led to 3 groups. Conclusion: There was no significant difference in the upper airway width in 3 groups, but the tendency was that the upper airway width increased in the order of Angle class Ⅱ, Ⅰ and Ⅲ Besides. There was significant difference in the upper airway width between Angle class Ⅱand Ⅲ. And there was significant difference in the sagittal position of tongue.更多还原
