方法应用CT测量50例(男30,女20)头颅小脑延髓池安全穿刺深度和头最大长、眉间点至枕外隆凸点长,作了相关和回归分析。
Methods Correlation of safety paracentesis depth in cerebellomedullary cistern , maximum heads length and glabella inion line of 50 adults ( 30 males and 20 females ) head specimens were measured by CT . It was done the correlation and regression analysis .

枕外隆凸显著(41.67%)。
External occipital protuberance was obvious ( 41.67 % ) .
-
方法:在枕外隆凸下缘中点处作T字型切口,去除左侧枕骨。
Methods Make in the next the middle point of the type of T slice , do away with the left side Occipital bone .

结果:枕外隆凸到颧弓根连线为横窦标志。(2)颧弓拆装;
Results : The line connecting the root of the zygoma with the inion was used to locate the distal transverse sinus . ( 2 ) zygomatic arch disassemble approach ;
-
结果实验所收集的数据表明在定位横窦下缘和窦汇时,上项线及枕外隆凸尖不是一个可靠的浅表解剖学标志。
Results The data of this study showed that the superior nuchal line and inion is not always a reliable external anatomical mark to locate the transverse sinus and torcular herophili .

结果小脑延髓池安全穿刺深度为男3834±369mm,女3553±339mm,由头最大长和眉间点至枕外隆凸点长推导出推算小脑延髓池安全穿刺深度的男、女两个回归方程。
Results The safety paracentesis depth in the cerebellomedullary cistern are 38.34 ± 3 69 mm ( male ) and 35 53 ± 3 39 mm ( female ), maximum heads length and glabella inion line calculated two regression equation of safety paracentesis depth in the cerebellomedullary cistern .
