摘　　要：目的分析正常成年人面积-距离曲线,得到大多数人面积-距离曲线上前两个最小横截面积(the first minimum cross-sectional area,MCA1;the second minimum cross-sectional area,MCA2)和整个鼻腔的最小截面积(total minimum cross-sectional area,MCA)的常见位置。方法正常成年人103例,年龄18～60岁,平均(35.6±12.6)岁,其中男性49例(98侧鼻腔),年龄18～60岁,平均(35.7±13.3)岁;女性54例(108侧),年龄18～60岁,平均(35.6±11.9)岁。利用Eccovision鼻声反射仪测量得到面积-距离曲线及MCA1,MCA2,MCA及其距前鼻孔的距离。结果多数受试者的MCA1位于前鼻孔附近,多数受试者的MCA2位于距前鼻孔2 cm的距离附近,与下鼻甲前端出现的位置基本一致,多数受试者MCA多位于鼻阈至下鼻甲前端出现的位置之间。结论MCA能客观地反映鼻腔的通畅程度,特别是将分析片断定于1 cm以后则更有意义。OBJECTIVE To obtain the areadistance curve of nasal airway in normal Chinese adults and analyze the location of the two first minimum crosssectional area （The first minimum cross-sectional area： MCA1, the second minimum cross-sectional area： MCA2） and the total minimum cross-sectional area（MCA）. METHODS One hundred and three normal Chinese adults were recruited. There were 49 males and 54 females. The age ranged from 18 to 60 years old （ mean 35.6＋12.6 years）. The Eccovision acoustic Rhinometry was used to obtain the area-distance curve of 0 to 5cm nasal cavity. RESULTS Most of MCA1 were near the nostril, most of the MCA2 were at about 2cm from the nostril around the head of the inferior turbinate, and almost all the MCA were between the limen nasi and the head of the inferior turbinate. CONCLUSION MCA is very useful in objective evaluation of the patency of nasal airway, especially when the analyzing segment is set lcm far from the nostril.
