中国人鼻软骨的解剖和CT三维图像测量

目的测量中国人鼻软骨（鼻翼软骨、鼻中隔软骨和侧鼻软骨）的解剖学数据,并与其他人种相比较。方法20具（40侧）成人尸体标本,取下鼻翼软骨40枚,鼻中隔软骨20枚,侧鼻软骨40枚。参考Zelnik和Ofodile的测量参数,利用CT三维图像测量相关解剖数据,SPSS11．5软件进行统计学处理。结果中国人鼻翼边缘到鼻翼软骨的距离从内到外分别是（4．54±0．59）、（5．54±0．69）、（10．45±1．15）mm;鼻翼软骨外侧脚的长、宽、厚分别为（18．51±1.63）、（7．99±1．66）、（0．49±1．28）mm。结论白种人的鼻软骨最大,其他人种在伯仲之间。

Three-dimensional image reconstruction and anthropometry of nasal cartilages in Chinese

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.
