Morphometric Study of the Trachea in Korean / 체질인류학회지

ABSTRACT

This morphometric study of the trachea was performed to provide the basic data necessary for shielding crico-thyroid membrane incision, tracheal intubation and tracheotomy in korean bodies 48 (33 male, 15 female). Tracheal measurement included the number, the length, the anteroposterior and transverse diameters of trachea, and the height of tracheal cartilages, and the inter-rings distances of cartilages. The length of trachea was 104.0+/-1.4 mm in male and 102.3+/-1.9 mm in female, but there was no significance between males and females. All of the anteroposterior and transverse diameters, and the height were longer in males, compared with females, in the first, fifth, tenth and fifteenth tracheal cartilages. The anteroposterior and transverse diameters of the first and fifteenth tracheal rings, and the height of the first tracheal ring differed significantly male's from female's. The distances between posterior end of rings of the first, tenth and fifteenth tracheal cartilages were broader in males. The inter-rings distances of tracheal cartilage were also wider in the male, and showed significant differences in the 1st~2nd and 10~11th. These results suggest that this might be useful as a clinical basic data for the emergency physician, anesthetist, and associated medical doct
