Interactive virtual simulation was performed by modifying the 3D CG data to imitate various surgical procedures, such as bone drilling, brain retraction, and tumor removal, with manipulation of a haptic device. The authors also produced color-printed plaster models of modified 3D CG data by a selective laser sintering method and observed them under the operative microscope.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In all patients, IVS provided detailed and realistic surgical perspectives of sufficient quality, thereby allowing surgeons to determine an appropriate and feasible surgical approach. Surgeons agreed that in 44% of the 25 operations IVS showed high utility (as indicated by a rating of \u201cprominent\u201d) in comprehending 3D microsurgical anatomies for which reconstruction using only 2D images was complicated. Microscopic observation of color-printed plaster models in 12 patients provided further utility in confirming realistic surgical anatomies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The authors' presurgical simulation method applying advanced 3D imaging and modeling techniques provided a realistic environment for practicing microsurgical procedures virtually and enabled the authors to ascertain complex microsurgical anatomy, to determine the optimal surgical strategies, and also to efficiently educate neurosurgical trainees, especially during surgery for skull base and deep tumors.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/2013.3.jns121109","type":"journal-article","created":{"date-parts":[[2013,4,12]],"date-time":"2013-04-12T10:05:06Z","timestamp":1365761106000},"page":"94-105","source":"Crossref","is-referenced-by-count":74,"title":["Interactive presurgical simulation applying advanced 3D imaging and modeling techniques for skull base and deep tumors"],"prefix":"10.3171","volume":"119","author":[{"given":"Makoto","family":"Oishi","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Brain Research Institute, Niigata University, Niigata; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masafumi","family":"Fukuda","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Brain Research Institute, Niigata University, Niigata; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoki","family":"Yajima","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Brain Research Institute, Niigata University, Niigata; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenzo","family":"Yoshida","sequence":"additional","affiliation":[{"name":"3D Solution, Toyotsu Machinery Corporation, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Machiko","family":"Takahashi","sequence":"additional","affiliation":[{"name":"3D Solution, Toyotsu Machinery Corporation, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetsuya","family":"Hiraishi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Brain Research Institute, Niigata University, Niigata; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetsuro","family":"Takao","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Brain Research Institute, Niigata University, Niigata; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akihiko","family":"Saito","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Brain Research Institute, Niigata University, Niigata; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yukihiko","family":"Fujii","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Brain Research Institute, Niigata University, Niigata; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-jns121109","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"591","DOI":"10.3171\/jns.2004.100.4.0591","article-title":"Intraoperative stereoscopic QuickTime Virtual Reality","volume":"100","author":"Balogh","year":"2004"},{"key":"b2-jns121109","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"499","DOI":"10.1227\/01.NEU.0000047813.32607.68","article-title":"A threedimensional interactive virtual dissection model to simulate transpetrous surgical avenues","volume":"52","author":"Bernardo","year":"2003"},{"key":"b3-jns121109","series-title":"World Neurosurg","doi-asserted-by":"publisher","first-page":"106","DOI":"10.1016\/j.wneu.2010.09.033","article-title":"The use of a three-dimensional novel computer-based model for analysis of the endonasal endoscopic approach to the midline skull base","volume":"75","author":"de Notaris","year":"2011"},{"key":"b4-jns121109","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"463","DOI":"10.1227\/00006123-199409000-00015","article-title":"Combined and three-dimensional rendered multimodal data for planning cranial base surgery: a prospective evaluation","volume":"35","author":"Gandhe","year":"1994"},{"key":"b5-jns121109","series-title":"Neurol Med Chir (Tokyo)","doi-asserted-by":"publisher","first-page":"335","DOI":"10.2176\/nmc.41.335","article-title":"Efficacy of navigation in skull base surgery using composite computer graphics of magnetic resonance and computed tomography images","volume":"41","author":"Hayashi","year":"2001"},{"key":"b6-jns121109","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"144","DOI":"10.3171\/jns.2002.96.1.0144","article-title":"Interactive stereoscopic virtual reality: a new tool for neurosurgical education.
