In this paper, the authors' goal was to report their novel presurgical simulation method applying interactive virtual (IVS) using 3D computer graphics (CG) data and microscopic observation of color-printed plaster models based on these CG in surgery for skull base deep tumors.For 25 operations 23 patients with or intracranial tumors (meningiomas, schwannomas, epidermoid tumors, chordomas, others), authors carried out created by image analysis radiological data. Interactive performed modifying imitate various surgical procedures, such as bone drilling, brain retraction, tumor removal, manipulation a haptic device. The also produced modified selective laser sintering observed them under operative microscope.In all patients, IVS provided detailed realistic perspectives sufficient quality, thereby allowing surgeons determine an appropriate feasible approach. Surgeons agreed that 44% showed high utility (as indicated rating "prominent") comprehending microsurgical anatomies which reconstruction only 2D images complicated. Microscopic 12 further confirming anatomies.The advanced imaging modeling techniques environment practicing procedures virtually enabled ascertain complex anatomy, optimal strategies, efficiently educate neurosurgical trainees, especially during tumors.
