目的探讨颅外体表参考线与大脑前、后联合(AC-PC)线之间的关系.为脑功能性立体定向手术的颅内靶点定位提供可靠、准确的体表参考线.方法收集我院2005年11月至2010年3月39例颅内肿瘤患者的头颅MRI神经导航资料,在GE Insta Trak 3500导航工作站中打开,在轴面与矢状面上将AC-PC线通过一系列的水平移动移至颅外并通过眼外眦,测量该线到外耳门中心的距离.结果 AC-PC线同一轴面体表平行线距离外耳门中心点的距离:男(49.31±6.28)mm,女(46.60±6.13)mm,男女差异有统计学意义,总体均数为(47.71±6.26)mm.通过眼外眦AC-PC平行线距离外耳门中心点的距离:男(32.27±6.32)mm,女(27.41±5.79)mm,检验结果差异有统计学意义.结论使用神经导航测量AC-PC线的颅外体表平行线方法直接、可靠.通过眼外眦的AC-PC线的平行线距离外耳门中心距离男女之间不同.

Objective To study the correlation between extracranial reference line and intracranial AC -PC line for finding an extracranial scan basic line and using it as reference line before stereotactic intracranial neurosurgery.Methods Brain MRI images neuronavigation data of 39 patients of intracranial tumors admitted to our hospital from Nov.2005 to March 2010 were analyzed.The data were treated by GE Insta Trak 3500 navigation workstation.The AC - PC line was moved to extracranial surface parallelly in sagittal plane and axial plane.The distances from these lines to the center of external mestus were measured.Results The distance from the parallel line of AC - PC line in the same axial plane to the central of external mestus in males and females were ( 49.31 ± 6.28 ) mm and ( 46.60 ± 6.13 ) mm respectively and the general average was (47.71 ± 6.26 )mm.There was no difference between males and females.The distance from the line , being the parallel line of AC - PC line and outer canthus, to the central of external mestus in males and females were (32.23 ± 6.32 )mm and (27.41 ± 5.79)mm respectively .The results showed statistical difference.Conclusion Using neuronavigation to measure extral cranial line of AC - PC line is direct and reliable.The distances from the line , being the parallel line of AC - PC line and crossing outer canthus, to the central of external mestus in males and females are different.
