Utility of multi-material three-dimensional print model in preoperative simulation for glioma surgery
Abstract
Although the three-dimensional (3D) printing technology has spread in the field of neurosurgery, the use of 3D print models concerning glioma surgery has rarely reported. For glioma surgery, some preoperative and intraoperative assistive methods have been developed to avoid injury to the cortex and fiber that are related to the neurological function. Furthermore, in order to perform preoperative simulation of glioma surgery, we created a 3D print model using a multi-material 3D printer that provided the flexibility of adjusting the color, hardness, and translucency of each structure arbitrarily. The use of 3D print model was demonstrated in one case involving an intramedullary tumor in the right temporal lobe. The tumor, optic radiation, brain parenchyma, tentorium, ventricle, and sinus were constructed in a single model in one printing process. Design of the degree of resection, insertion of the fence-post, and tumor resection paying attention to the optic radiation were simulated preoperatively using this model. The surgery was performed generally as the simulation and gross total removal of the tumor was achieved. This model was useful for understanding the degree of resection, adequate insertion of the fence-post, and the relationship of the tumor with other important structures. A variety of printing materials contributed to make the model realistic and to understand anatomical relationship. In conclusion, the 3D print model can supplement an image of some portions that are not visible perioperatively and serve as a preoperative assistant modality.
