Anatomical Shape of the Airways in Two Different European Populations

Lateral radiographs of the airways were taken in 20 men and 24 women lying supine with the neck in the normal position. The mean configuration of the airways for men and women is presented in a standard coordinate system. The results (contours of the airways) are compared to those of a Swedish study since the same method was applied in order to find out, if the established model is valid for other populations. Significant differences were found between the two population groups as well as between males and females. This indicates both inter-racial and inter-sexual modification of the anatomical shape of the airways.
