Abstract

The thyroid cartilage is located just below the hyoid bone and is the biggest cartilage in laryngeal cartilage. The purpose of this study is to identify the sex based on the morphological analysis of the thyroid cartilage of Koreans. This study was carried out on the thyroid cartilage of 109 specimens of adult subjects (age over twenty years old) including 69 males and 40 females. We measured 27 measurements, followed by the statistic procedures. The results were as followed ; 1. Male subjects exhibited larger values of width, height and length of the thyroid cartilage and height of lamina than female subjects (p < 0.01). 2. Female subjects exhibited larger values of angle of lamina, angle of inferior horn and angle of upper margin of lamina than male subjects (p < 0.01). 3. Discriminant functions were obtained with the measurement values of length of the thyroid cartilage and height of lamina. In conclusion, the thyroid cartilage in Korean is different depending on sexes. Therefore we can identify the sex for over twenty years old Koreans by the morphometric analysis of the thyroid cartilage.
