摘要
目的：探讨年轻成年男性无鼾症错[牙合]畸形患者上气道大小与牙[牙合]结构的相关性。方法：52例男性无鼾症的错[牙合]畸形患者（年龄18—24岁，平均19岁），正畸治疗前拍摄头颅定位侧位片，选择有代表性的牙颌结构测量参数为自变量，以上气道间隙参数为因变量，进行两者间的逐步回归统计学分析。结果：软腭后气道间隙（SPAS）与下颌矢向位（SNB角）、前颅底长度（S-N）、舌骨矢向位（H—C3距）呈正相关；软腭尖后气道间隙（MAS）与H-3C，距、SNB角呈正相关，与下切牙倾斜度（L1—MP角）呈负相关；舌根后气道间隙（IAS）与SNB角、H-C3距、S-N距呈正相关，与L1-MP角呈负相关。结论：年轻成年男性无鼾症错[牙合]畸形患者上气道大小与牙颌结构及舌骨位置密切相关。
Objective：To investigate the correlation of dentofacial structure and the sagittal size of the upper airway in youthful nonsnoring men with malocclusion. Methods：Lateral cephalometry was carried out in 52 nonsnoring males with malocclusion. The average age of the patients was 19.23 years, with a range of 18 to 24 years. Stepwise regression analysis was used to relate those cephalometric parameters to the sagittal airway size at different levels. Results： SNB angle,S-N length and H-C3 length were the related variables to superior posterior airway space（ SPAS ）. H-C3 length,SNB angle and L1-MP angle were the related variables to middle airway space（MAS）. SNB angle, H-C3 length,S-N length and LI-MP angle were the related variables to inferior airway space（IAS）. Conclusion：The sagittal upper airway size in youthful nonsnoring men with malocclusion is correlated to the dentofacial structure and the hyoid position.
