摘要:

 目的 探讨现代西藏世居藏族正常青年人颅型特征。  方法 以拉萨市籍自愿参加的世居藏族青年人为研究对象。利用西门子 MAGNETOM ESSENZA 1.5T 磁共振扫描仪,使用3D-fSPGR序列扫描,有效调查对象93例,年龄18~44岁,平均年龄(28.52±8.76)岁,其中男性37例,女性56 例。利用工作站自带的图像处理软件测量,按照国际学术界通用的方法测量颅骨最大长、颅骨最大宽和颅高,并计算颅长宽指数、颅长高指数Ⅰ、颅宽高指数。  结果 男性与女性颅骨最大长比较差异有统计学意义(t=7.304,P<0.01),颅骨最大宽比较差异有统计学意义(t=5.780,P<0.01),颅高比较差异有统计学意义(t=5.107,P<0.01)。经 Spearman 相关分析,女性颅骨最大长与年龄成正相关(r=0.264,P<0.05),颅长高指数Ⅰ与年龄成负相关(r=-0.303,P<0.05)。  结论 现代西藏世居藏族正常青年人颅长宽指数分型以圆颅型为主,颅长高指数分型以高颅型为主,颅宽高指数分型男性以阔颅型为主,女性以中颅型为主。

Abstract:

Objective To study the cranial characteristics of normal young people living in modern Tibetan.   Methods With the voluntary participation of Tibetan young people as the research object. Using Siemens MAGNETOM ESSENZA 1.5T Magnetic resonance scanner, and using 3D-fSPGR sequence scanning, effective investigation of 93 cases, age 18-44 years old, average age (28.52±8.76) years was carried out. There were 37 male cases and 56 female cases. Manual measurement of maximum cranial length, maximum cranial breadth and basi-bregma heigh, and calculation of cranial index, cranial length-height index Ⅰ, cranial breadth height index were obtained.   Results The difference between male and female maximum cranial length was statistically significant (t=7.304,P<0.01), the difference of maximum cranial breadth was statistically significant (t=5.780,P<0.01), and the difference of basi-bregma heigh was statistically significant (t=5.107,P<0.01). By Spearman correlation analysis, the female maximum cranial length was positively correlated with the age (r=0.264,P<0.05), and the cranial length-height index Ⅰ was negatively correlated with the age (r=-0.303,P<0.05).   Conclusion The cranial index of normal young people in modern Tibet is divided into male and female with brachycrany, male and female with hypsicrany of cranial length-height index I, the main cranial breadth-height index is dominant in male with tapeinocrany, female are dominated by metriocrany.
