Acoustic rhinometry (AR) has been used as a specific test for nasal patency.
this study aimed to set the reference values for nasal cavity cross-section geometry in healthy adults through AR.
this is a clinical prospective study.
thirty volunteers (14 males and 16 females) without signs of nasal obstruction and aged between 18 and 30 years were enrolled in this study. They were assessed before and after being treated topically with a nasal vasoconstrictor drug. Their nasal cross-sectional areas were measured at the three dips of the rhinogram, corresponding respectively to the nasal valve (CSA1), the anterior (CSA2), and the posterior (CSA3) region of the inferior and middle turbinate.
the mean areas (+/-SD) for 60 nasal cavities before nasal vasoconstriction were: 0.54+/-0.13cm2 (CSA1), 0.98+/-0.31 cm2 (CSA2), and 1.42+/-0.44cm2 (CSA3). After vasoconstriction, the mean values of the three segments analyzed were significantly larger (p<0.05). Gender was not a statistically significant variable.
The nasal cross-sectional areas obtained for adults may be used for control purposes when studying patients with nasal obstruction, in conjunction with the nasal volume values previously reported by our group.
鼻声反射测量法（AR）已被用作评估鼻腔通畅度的一项特定检查。
本研究旨在通过鼻声反射测量法确定健康成年人鼻腔横截面几何形状的参考值。
这是一项临床前瞻性研究。
招募了30名志愿者（14名男性和16名女性），年龄在18至30岁之间，无鼻塞迹象。在局部使用鼻血管收缩药物治疗前后对他们进行评估。在鼻声反射图的三个凹陷处测量他们的鼻腔横截面积，分别对应鼻瓣膜（CSA1）、下鼻甲和中鼻甲的前部（CSA2）以及后部（CSA3）区域。
在使用鼻血管收缩剂之前，60个鼻腔的平均面积（±标准差）为：0.54±0.13平方厘米（CSA1）、0.98±0.31平方厘米（CSA2）和1.42±0.44平方厘米（CSA3）。血管收缩后，所分析的三个节段的平均值显著更大（p<0.05）。性别不是一个具有统计学意义的变量。
在研究鼻塞患者时，结合我们小组先前报告的鼻腔容积值，所获得的成年人鼻腔横截面积可用于对照目的。
