The authors report on their experience with a 3D virtual reality system for planning minimally invasive neurosurgical procedures.
Between October 2002 and April 2006, the authors used the Dextroscope (Volume Interactions, Ltd.) to plan neurosurgical procedures in 106 patients, including 100 with intracranial and 6 with spinal lesions. The planning was performed 1 to 3 days preoperatively, and in 12 cases, 3D prints of the planning procedure were taken into the operating room. A questionnaire was completed by the neurosurgeon after the planning procedure.
After a short period of acclimatization, the system proved easy to operate and is currently used routinely for preoperative planning of difficult cases at the authors' institution. It was felt that working with a virtual reality multimodal model of the patient significantly improved surgical planning. The pathoanatomy in individual patients could easily be understood in great detail, enabling the authors to determine the surgical trajectory precisely and in the most minimally invasive way.
The authors found the preoperative 3D model to be in high concordance with intraoperative conditions; the resulting intraoperative "déjà-vu" feeling enhanced surgical confidence. In all procedures planned with the Dextroscope, the chosen surgical strategy proved to be the correct choice. Three-dimensional virtual reality models of a patient allow quick and easy understanding of complex intracranial lesions.
作者报告了他们使用三维虚拟现实系统进行微创神经外科手术规划的经验。
在2002年10月至2006年4月期间，作者使用Dextroscope（Volume Interactions有限公司）为106例患者规划神经外科手术，其中包括100例颅内病变患者和6例脊柱病变患者。规划在术前1至3天进行，12例患者在规划过程中的三维打印模型被带入手术室。规划过程完成后，神经外科医生填写了一份问卷。
经过短时间的适应后，该系统证明易于操作，目前在作者所在机构常规用于困难病例的术前规划。人们认为，使用患者的虚拟现实多模态模型显著改善了手术规划。能够轻松、详细地了解个体患者的病理解剖结构，使作者能够以最微创的方式精确确定手术轨迹。
作者发现术前三维模型与术中情况高度一致；由此产生的术中“似曾相识”感增强了手术信心。在所有使用Dextroscope规划的手术中，所选的手术策略被证明是正确的选择。患者的三维虚拟现实模型有助于快速、轻松地理解复杂的颅内病变。
