摘要
目的 :探讨国人头颅形态的基本特征及其与颅骨有关结构的相关性。方法 :随机抽取我院颅脑CT扫描结果阴性的 1 0 7例受检者 (年龄 1 7~ 89岁 ,平均 4 7.0 5岁 ,男 1 0 1例 ,女 6 9例 )的影像资料 ,排除颅脑病变和先天性畸形。测量头颅前后径、横径、岩矢角的角度、枕内粗隆及筛骨鸡冠的高度。计算头指数 ,并对头颅分型 ,分析头型与所测解剖结构间的相关性。结果 :本组研究对象中长头型 1 2例 (7% ) ,中头型 5 5例 (32 .4 % ) ,圆头型 1 0 3例(6 0 .6 % )。 3种头型之间岩矢角的差异具有统计学意义 (P <0 .0 1 ) ,而枕内粗隆和筛骨鸡冠的高度在各头型间差异无显著性。头颅指数与枕内隆突的高度呈负相关 (P <0 .0 1 ,r=- 0 .2 0 1 ) ,与岩矢角的大小呈正相关 (P <0 .0 1 ,r =0 .4 8)。结论 :国人头型以圆头型居多。头型与颞骨岩矢角及枕内粗隆的解剖学特征存在一定相关性 。
Objective: To investigate the essential characters of head form of Chinese and its correlation with relative skull. Methods: 170 cases with negative result of brain CT scan were randomly selected, excluding the cases with brain pathological changes and congenital abnormality. The fore and aft and transverse distance of the head, the angle of temporal petrous, the height of internal occipital protuberance and crista galli of ethmoid were measured. The cephalic index was calculated. Results: According to the cephalic index, the 107 cases were classified into three types of head form, dolichocephalic skull (12 cases, 7%), mesocephalic skull (55 cases, 32.4%) and brachycephalic skull (103 cases, 60.6%). The difference of the angle of temporal petrous among different head form was significant( P <0.01). There was a negative correlation between head form and height of internal occipital protuberance( P <0.01, r =-0.201) and a positive correlation between head form and the angle of temporal petrous( P <0.01, r =0.48). Conclusion: The majority of head form in Chinese is brachycephalic skull. It is confirmed that the correlation exists between head form and the angle of temporal petrous, as well as the height of internal occipital protuberance. It also influences the quality of CT scan of brain.
