    • 摘要: 目的:在构建虚拟现实解剖模型基础上,探讨远外侧入路经枕髁和经颈静脉突两种不同方向的微创手术路径对相关解剖结构显露的影响。方法对15例尸头标本行头颅CT和MR扫描,影像数据输入Vitrea Fx 3.0虚拟现实系统构建颈静脉孔区3D解剖模型。在模型的颅后窝中选取颈静脉结节前缘为标志点,分别做经枕髁和经颈静脉突两个方向的、直径1 cm的圆柱体模拟远外侧入路微创手术路径,观察路径中的解剖结构、测量其体积,并采用配对t检验进行分析比较。结果两种方向的模拟手术路径中均可清晰显示所包含的颅底骨质、神经和血管等解剖结构,均不包含脑干、小脑、椎动脉和小脑后下动脉。经枕髁方向路径包含部分迷走神经、副神经,经颈静脉突方向手术路径包含部分颈内静脉和颈静脉球。经枕髁和经颈静脉突两种方向手术路径体积[(3236.20±228.01) mm3 vs (3306.00±248.23) mm3]及路径中舌下神经的体积差异均无统计学意义(P值均>0.05)。经枕髁方向路径中包含的骨性结构和小脑前下动脉的体积大于经颈静脉突方向路径,而包含的静脉的体积小于经颈静脉突方向路径,差异均有统计学意义( t=7.324、56.526、140.580, P值均0. 05). The volumes of osseous structures and anterior inferior cerebellar artery involved in trans-condyle route were more than those in trans-jugular process route with statistically significant differences. The volume of vein in trans-jugular process route was more than that in trans-condyle route with statistically significant difference(t=7. 324, 56. 526, 140. 580, all P values <0. 01). Conclusions The routes from two directions in the far lateral approach can expose hypoglossal nerve effectively, of which trans-condyle route is prone to expose anterior inferior cerebellar artery. Trans-jugular process route can bypass the lower cranial nerve but with the risk of vein injury.

    • 摘要: Objective To explore the preliminary application of the construction of anatomic model of falx meningioma entity based on 3D printing technology in the surgical treatment of falx meningioma. Methods Three patients with falx meningioma admitted in Department of Neurosurgery of Fujian Provincial Hospital from April to June 2015 were selected. According to the DICOM data of patients obtained from enhanced spiral CT scanning,data information of skull,blood vessel and tumor were extracted and reconstructed with different segmentation methods. The assembly and integration of the three ones were achieved in the same coordinate system to form three - dimensional visual composite virtual models. Combined with 3D printing technology,three - dimensional visual composite virtual model was substantialized. The construction of anatomic model of falx meningioma entity and the operation of falx meningioma for patients were observed. Results The three - dimensional visual composite virtual models were constructed for three patients and the anatomic models of falx meningioma entity were made successfully,which could clearly show the relationship between tumor and skull,cerebral falx,superior sagittal sinus,inferior sagittal sinus and peripheral vessels. Surgeons could use this model to make perfect operation plan,guide surgical positioning and implementation according to anatomic model of falx meningioma entity during operation,avoid important blood vessels and reach Simpson Ⅰ grade excision. Moreover,patients had no obvious encephaledema,hematoma and dysneuria after operation. The operation was successful in three patients. Conclusion The anatomic model of falx meningioma entity based on 3D printing technology can effectively guide medical staff to make and improve operation plans,precisely remove tumor,reduce intra -operation injuries,and contributes to the rehabilitation of patients.%目的:探究基于3D 打印技术的大脑镰旁脑膜瘤实体解剖模型构建在大脑镰旁脑膜瘤切除术中的初步应用情况。方法选取2015年4—6月福建省立医院神经外科收治的大脑镰旁脑膜瘤患者3例,根据患者螺旋 CT 增强扫描所得的 DICOM 数据,针对颅骨、血管和肿瘤等组织结构采用不同的分割方法进行数据信息提取和重建,并在同一坐标系下实现装配和三者融合,形成三维可视化复合虚拟模型,再结合3D 打印技术将三维可视化复合虚拟模型实体化。观察大脑镰旁脑膜瘤实体解剖模型构建情况及患者大脑镰旁脑膜瘤切除术的手术情况。结果3例患者均构建出三维可视化复合虚拟模型,并成功制作出大脑镰旁脑膜瘤实体解剖模型,且其可清晰显示肿瘤与颅骨、大脑镰、上下矢状窦及周边血管的关系。手术医师利用该模型制定出完善的手术预案,术时根据大脑镰旁脑膜瘤实体解剖模型指导手术定位与实施,避开重要血管,达到 Simpson Ⅰ级切除,且患者术后无明显脑水肿、血肿及神经功能障碍,手术成功。结论基于3D 打印技术的大脑镰旁脑膜瘤实体解剖模型能有效指导医务人员制定与完善手术方案,精准切除肿瘤,减少术中损伤,有助于患者康复。
