：研究广东地区健康青年人鼻声反射参数：鼻限流节段的部位、鼻腔最小横截面积（ＮＭＣＡ）、鼻腔容积（ＮＣＶ）和鼻阻力（ＮＲ）的正常值，以及它们之间的关系。方法：应用声反射鼻测量计对２７６例该地区健康青年进行测试，同时对所得到的各种峰型进行分析。结果：７３％鼻腔限流节段的部位位于鼻内孔稍后，距前鼻孔的距离（ＤＣＡＮ）为：男１．３６±０．５３ｃｍ，女１．０６±０．４６ｃｍ，两者之间存在显著性差异（Ｐ＜０．０５）；男女之间的ＮＭＣＡ，ＭＣＶ及ＮＲ无显著性差异。经过多元回归检验，ＮＲ与ＮＭＣＡ的相关性最大，与ＮＣＶ的相关性次之，而与ＤＣＡＮ的相关性不大。结论：提示鼻瓣的意义不在于其位置，而在于其大小；界声反射测量为一种准确客观的鼻腔通气状态测量手段，但不同的人群应有不同的鼻声反射参数的正常值，注意了这一点才可以广泛地用于科研和临床。
: To study the nasal reflex parameters of healthy young people in Guangdong: the site of nasal flow-limiting segments, the normal nasal area (NMCA), nasal volume (NCV) and nasal resistance (NR), and the relationship between them. Methods: A total of 276 healthy young people in this area were tested with acoustic reflex nasal meter. At the same time, various types of peaks were analyzed. Results: 73% of nasal limiting segments were located in the nasal hole later, and the distance from the anterior nostril (DCAN) was 1.36 ± 0.53 cm in male and 1.06 ± 0.46 cm in female, There was significant difference (P <0.05); There was no significant difference between male and female NMCA, MCV and NR. After multiple regression test, NR had the highest correlation with NMCA, followed by NCV, but not with DCAN. CONCLUSIONS: The significance of nasal valve is not located in its position but in its size. Boundary acoustic reflectometry is an accurate and objective measure of nasal ventilation, but different populations should have different normal values of nasal reflex parameters. This can be widely used in scientific research and clinical.
