한국인후두에 관한 체지인류학적 연구 제1편 후두연골에 관하여
Anthropological Studies on the Larynx in Korean Part Ⅰ. The Laryngeal Cartilages
- Issue Date
- Seoul J Med, Vol.3 No.1, pp. 51-65
- The author carried out measurements and observations
on the laryngeal cartilages obtained from 35 male
and female adults and discussed statically the significance
between the mean values in male and females. Comparison
with other races was also made.
From these studies, the following conclusions were
1) The maximal diameter and the size of each part of
the thyroid cartilage are larger in males than in
females except the angle of the superior thyroid
notch. the degree of inclination of the superior
cornu and the anterior angle of the thyroid cartilage.
These are in general smaller than those of European
and Alsatian, about equal to those of Chinese,
about equal or somewhat larger than those ofJapanese, and larger than those of the Aborigines
2) The thyroid foramen is found in 50.3±6.5% of the
total cases and most frequently it is on the left
side, 32.1±6.13% of the total cases. Most frequently
it is located below the superior thyroid tubercle,
77.8±6.6% of the cases with foramen present. The
thyroid foramen appears in Koreans as frequently
as in Europeans and Chinese, and more frequently
than in Japanese.
3) The size of each item of the cricoid and arytenoid
cartilages is larger in males than in females except
the height of the lamina, the distance between the
inner margins of both arytenoid articular surfaces,
the sagittal diameter of arytenoid articular surface
and the height of the arytenoid cartilage. These are
in general smaller than those of European and Alsatian,
aboutequal to those of Chinese, about equal
or somewhat larger than those of Japanese and
larger than those of the Aborigines of Formosa.
4) The thyroid articular surfaces of the cricoid cartilage
are absent in 32.7±O.16% of the total cases.
This is comparable with the findings in Japanese
5) Type-a epiglottis is seen most frequently, 54.5±6.54
% of the total cases, and type-b is seen next in
order, 29.1±5.9%. This is almost indentical to the
findings in Japanese.
