Abstract:
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.
