ABSTRACT

This study is aimed to measure the morphology of Korean cricoid cartilages. A total of 48 - 33 males and 15 females - cadavers were used in this study. When it comes to their average age, males were 70 years old (50 to 91 years old), and females were 74 years old (47 to 92 years old). For this study, anteroposterior diameter and transverse diameter of superior side, anteroposterior diameter of inferior side, height of arch and lamina, anterior and posterior thickness of cricoid cartilages were measured. Anteroposterior diameters of superior and inferior cricoid cartilage were 28.5, 18.78 mm in male, and 23.85, 15.97 mm in female, respectively. And transverse diameters of superior side were 17.19 mm in male and 13.36 mm in female. Heights of arch and lamina were 7.10, 22.33 mm in male and 5.72, 20.10 mm in female, respectively. Thickness of anterior arch and posterior lamina were 2.57, 2.83 mm in male and 2.22, 2.42 mm in female, respectively. As a result, most Korean male measurements were significantly longer than female measurements except the anterior and posterior thickness of cricoid cartilages. Moreover the majority of measurements were shorter than Nigerians or Europeans. However, they were very similar to American Indians’ measurements. In conclusion this study stated above can be a valuable foundation for the research of Korean cricoid cartilages’ anatomic structures and morphology.
