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.　©　2017　China　Anti-Cancer　Association.　All　rights　reserved.
