3D打印技术在蝶骨嵴脑膜瘤切除术中的应用价值

  目的  研究3D打印技术在蝶骨嵴脑膜瘤手术中的应用价值。  方法  选取福建省立医院2016年9月至2016年12月经头颅MRI及螺旋CT扫描发现的蝶骨嵴脑膜瘤患者5例，利用颅脑螺旋CT增强扫描的DICOM图像，针对颅骨、血管及肿瘤，分别进行数据信息的提取和重建，并在同一坐标系下实现装配融合，建立三维复合虚拟模型，再经3D打印技术制作出3D实体模型，于术前、术中参考。  结果  成功重建5例患者的蝶骨嵴脑膜瘤三维复合虚拟模型，并制作出实体解剖模型，模型清晰显示颅骨、肿瘤及其与毗邻血管的位置关系，将其应用于术前规划与术中参考，5例患者手术均获得成功。  结论  基于3D打印技术的蝶骨嵴脑膜瘤三维复合虚拟模型及其实体解剖模型在优化手术预案、提高肿瘤切除率、减少手术损伤等方面具有重要意义。 

Application value of 3D printing technology in the surgery of sphenoid ridge meningioma

  Objective  To investigate the value of 3D printing technology in sphenoid ridge meningioma dissection.  Methods  By using craniocerebral spiral enhanced CT scan DICOM images, the skull, vessels, and tumor were extracted, reconstructed, and assembled and integrated in the same coordinate system. Then, we constructed a 3D virtual model and a 3D-printed entity model, which was applied for preoperation and postoperation.  Results  Virtual models of the brains of five patients were reconstructed successfully and 3D entity models were produced. The models expressed the relationship among tumors, adjacent blood vessels, and the important position of the nerve tissue. Then, the models were applied to the reference before surgery planning and after surgery. Five cases were successfully performed.  Conclusion  The use of the entity model of sphenoid ridge meningioma is important in optimizing operation plans, improving tumor resection, and reducing intraoperative bleeding.
