The nose with normal feeling of nasal patency, and no gross structural changes has been described in 82 individuals by acoustic rhinometry. Curves for one and both sides of the nasal cavity and before and after decongestion have been recorded. We have found that the minimal cross-sectional area (MCA) is located anteriorly in the nasal cavity; in some subjects it is localized at the head of the inferior turbinate and in other subjects more anteriorly at the nasal valve. After decongestion MCA moves even more anteriorly. Beyond the MCA the dimension of the nasal cavity increases, with maximal effect of decongestion at 4 cm from nostrils. Decongestion increases the total volume of the nasal cavity by 35%.
通过鼻声反射仪对82名个体进行了研究，这些个体鼻腔感觉通畅正常，且无明显结构改变。记录了鼻腔一侧及两侧在使用减充血剂前后的曲线。我们发现，最小横截面积（MCA）位于鼻腔前部；在一些受试者中，它位于下鼻甲头部，而在另一些受试者中更靠前位于鼻瓣膜处。使用减充血剂后，MCA甚至更向前移动。在MCA之后，鼻腔尺寸增大，在距鼻孔4厘米处减充血效果最大。使用减充血剂使鼻腔总体积增加了35%。
