神经导航与直线测量法对定位矢状窦旁脑膜瘤准确性比较

Comparison of the accuracy of neuronavigation and linear measurement in the positioning of parasagittal meningioma

目的探讨神经导航与直线测量定位法在矢状窦旁脑膜瘤术前定位的准确性。方法2016年1月至2018年4月于蚌埠医学院第一附属医院神经外科,对38例手术治疗的矢状窦旁脑膜瘤患者进行术前定位,分别采用神经导航定位及直线测量定位法,术中观察肿瘤实际位置,比较两种方法定位的准确性。并记录神经导航定位及直线测量定位法所用时间,比较两种方法耗时是否有差异。结果所有病例分别采用神经导航定位及直线测量定位法,经过定位均完整暴露肿瘤。与术中测量实际肿瘤中心位置相比,38例神经导航定位与实际肿瘤中心位置平均误差距离(2.7±1.9)mm,直线测量定位与实际肿瘤中心位置平均误差距离为(3.2±1.3)mm,两组间比较差异无统计学意义(P>0.05)。神经导航包括开机、数据导入、注册、定位等,平均耗时(22.3±2.3)min。直线定位法包括影像资料测量、定位,平均耗时(1.7±0.3)min,两组间比较差异有统计学意义(P<0.001)。结论直线测量定位法与神经导航定位法对矢状窦旁脑膜瘤术前定位均具有很好的准确性。

Objective To explore the accuracy of preoperative positioning of neuronavigation and linear measurement localization in the parasagittal meningioma. Methods Thirty-eight patients with parasagittal meningioma who underwent neurosurgery in the First Affiliated Hospital of Bengbu Medical College from January 2016 to April 2018 were preoperatively positioned with neuronavigation localization and linear measurement localization. The actual position of the tumor was observed during operation, and the accuracy of the two methods was compared. The time taken by the neural navigation positioning and the linear measurement positioning method was recorded, and the difference between the two methods was compared. Results All cases were treated with neuronavigation and linear measurement, and the tumors were completely exposed after localization. Compared with the actual tumor center position measured during surgery, the average error distance between 38 nerve navigation and actual tumor center position was (2.7±1.9) mm, and the average error distance between linear measurement and actual tumor center position was (3.2±1.3) mm. The difference was not statistically significant, P value=0.207. Neuronavigation includes booting, data import, registration, positioning, etc., which takes an average of (22.3±2.3) minutes. The linear positioning method included image data measurement and localization, and the average time was(1.7±0.3) minutes. The difference between the two groups was statistically significant, and the P value was less than 0.001. Conclusion The linear measurement localization method and the neuronavigation localization method have good accuracy for preoperative localization of the parasagittal meningioma.
