A detailed cephalometric analysis of the soft and hard tissues of the upper airway was conducted with lateral cephalographs from 116 normal Chinese, aged between 18 and 25 years. Normal values and deviation range were preliminarily established for the size of the tongue, soft palate, nasopharynx, oropharynx, and hypopharynx, and for the relative position of the hyoid bone and vallecula in both sexes. Statistical findings showed that there were significant differences between the sexes. Significant relationships (P < 0.001) were observed 1) between the hypopharyngeal depth and the position of the hyoid bone and the vallecula, in which the horizontal position of vallecula appears to be the best predictor of the hypopharyngeal depth, as confirmed by the multiple regression equation; 2) between the upper airway depths at four different levels; and 3) between the naso-oropharyngeal area and tongue, soft palate, and oral area. The present data can be used to investigate further the upper airway in abnormal states.
对116名年龄在18至25岁之间的正常中国青年的头颅侧位片进行了上气道软硬组织的详细头影测量分析。初步确定了男女舌、软腭、鼻咽、口咽和下咽的大小以及舌骨和会厌谷相对位置的正常值和偏差范围。统计结果表明，男女之间存在显著差异。观察到显著相关性（P < 0.001）：1）下咽深度与舌骨和会厌谷位置之间，多元回归方程证实会厌谷的水平位置似乎是下咽深度的最佳预测指标；2）四个不同水平的上气道深度之间；3）鼻-口咽面积与舌、软腭和口腔面积之间。本研究数据可用于进一步研究异常状态下的上气道。
