目的:通过对正常头颅MRI资料的观测,为第三脑室造瘘术的手术定位提供参考数据.方法:对300例正常头颅MRI资料进行标注和测量,经统计学处理,得出第三脑室造瘘术的相关参考数据.结果:入颅点前、后距离之间的比值(BC/AC)在各年龄组之间差异无统计学意义(P＞0.05);手术入路参数值入颅点旁开中线距离(L)、内窥镜的人颅深度(H)、内窥镜与正中矢状面的夹角(a),≤9岁年龄组与其他年龄组之间差异均有统计学意义;得出了不同年龄组手术人路各项参数均值的95%可信区间.结论:头颈MRI在第三脑室造瘘手术中具有定位准确,适用范围广的优点,可为个体化手术治疗提供依据.

Objective: To provide references for the locating the third ventriculos tomy by measuring normal brain MRI data. Methods: Three hundreds normal brain MRI data were tagged and measured. The relevant reference data about third ventricle fistulization were obtained after statistics processing. Rosults: There were no statistical differences in the ratio of the distance before and after into the skull (BC / AC) in all age groups (P＞0.05). There were statistical differences in parameters of surgical approach-the distance of the middle line beside the incision (L),the depth inside the scalp (H) and the angle between the long axle of endoscope and the center sagittal plane (a) between ≤ 9-year--old and other age groups. The 95 percent confidence interval about parameters of surgical approach was obtained among all age groups. Conclusion: The results provide the reference of surgical treatment for the individual, enjoying the advantage of accuracy location and wide application.
