Sixty acoustic rhinographs from subjects of three different ethnic groups (Caucasian [Europeans], Negro, and Oriental) were examined at baseline and after decongestion. The main parameters analysed were minimal cross-sectional area (MCA), the distance at which this occurred (D), nasal volume at 0-4 cm (Vol), mean cross-sectional area at 0-6 cm (MA), and the cross-sectional area at 10 points in the nose (0, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, and 6 cm) analysed as a series (A). Values from left and right were combined and mean values used. Analysis was carried out using multiple linear regression and grouped linear regression with analysis of covariance and, for A, multifactorial analysis of variance. For MCA, race was the main determining factor with Orientals and Caucasians significantly lower than Negroes: p<0.0001 (corrected means and 95% confidence intervals [c.i.]: Orientals: 0.63 cm2, 0.55-0.71 cm2; Caucasians: 0.69 cm2, 0.62-0.77 cm2; Negroes: 0.87 cm2, 0.79-0.95 cm2). Height alone correlated with D in the decongested state (p<0.0001); race as well as height in non-decongested noses (p = 0.018). There were significant racial differences in Vol in both decongested (p = 0.014), and non decongested noses (p<0.0001). In the non-decongested state MA was significantly different in all racial groups: p<0.0001 (corrected means and c.i.: Orientals: 3.89 cm2, 3.47-4.31 cm2; Caucasians: 4.67 cm2, 4.27-5.09 cm2; Negroes: 5.13 cm2, 4.72-5.53 cm2). In the decongested state there was a significant difference between Negroes and the other two groups (p = 0.015), and Orientals and Caucasians were a homogenous population. We conclude that race has a significant effect on acoustic rhinometry measurements and this needs to be taken into account.
对来自三个不同种族群体（白种人[欧洲人]、黑人和东方人）的60份鼻声反射图在基线期和减充血后进行了检查。分析的主要参数有最小横截面积（MCA）、出现该横截面积时的距离（D）、0至4厘米处的鼻腔容积（Vol）、0至6厘米处的平均横截面积（MA）以及鼻内10个点（0、0.5、1、1.5、2、2.5、3、4、5和6厘米）处的横截面积并作为一个序列进行分析（A）。左右两侧的值合并后使用平均值。采用多元线性回归和分组线性回归并结合协方差分析进行分析，对于A则采用多因素方差分析。对于MCA，种族是主要决定因素，东方人和白种人显著低于黑种人：p<0.0001（校正均值和95%置信区间[c.i.]：东方人：0.63平方厘米，0.55 - 0.71平方厘米；白种人：0.69平方厘米，0.62 - 0.77平方厘米；黑种人：0.87平方厘米，0.79 - 0.95平方厘米）。在减充血状态下仅身高与D相关（p<0.0001）；在未减充血的鼻腔中种族以及身高也与D相关（p = 0.018）。在减充血（p = 0.014）和未减充血的鼻腔中Vol均存在显著的种族差异（p<0.0001）。在未减充血状态下所有种族群体的MA均有显著差异：p<0.0001（校正均值和c.i.：东方人：3.89平方厘米，3.47 - 4.31平方厘米；白种人：4.67平方厘米，4.27 - 5.09平方厘米；黑种人：5.13平方厘米，4.72 - 5.53平方厘米）。在减充血状态下黑种人与其他两个群体之间存在显著差异（p = 0.015），东方人和白种人是同质群体。我们得出结论，种族对鼻声反射测量有显著影响，这一点需要考虑在内。
