Abstract
Objective To conduct a morphologic and anatomic study on nasal cartilages (including nasal alar cartilage, nasal septal cartilage and upper lateral cartilage) in Chinese, and to compare measured parameters with the other races. Methods 20 adult embalmed cadavers were dissected, 40 nasal alar cartilages, 20 nasal septal cartilages and 40 upper lateral cartilages were collected and scanned by CT, and three-dimensional images were reconstructed. As Zelnik' and Ofodile's work, the data of the images were collected. Results The distances from the nostril rim to the caudal boarder of the lateral crus in the series were (4. 54 ±0. 59) mm anteriorly, (5. 54±0. 69) mm in the middle, and (10. 45± 1. 15) mm posteriorly. The length of the lateral crus was (18. 51 ±1. 63) mm, the width was (7. 99±1. 66) mm, and the thickness was (0. 49±1. 28) mm. Conclusion The Caucasian nasal cartilages are the biggest in all races, and the other's were approximately same. Key words: Nasal cartilages; Anatomy; Three-dimensional image reconstruction measurement
