Application of virtual reality system for individualized preoperative planning of sphenoidal ridge meningioma

To evaluate the usefulness of virtual reality (VR) technique for individualized preoperative planning of sphenoidal ridge meningioma. Multiple imaging data of CTA/MR were acquired from 41 surgical patients with sphenoidal ridge meningioma during the period from July 2009 to June 2013 were transferred into the Dextroscope system. A suite of built-in 3D tools enabled users to obtain measurement and simulated intraoperative viewpoint about the lesion and adjacent anatomic structures. A sophisticated preoperative plan was defined.Operative duration, total resection rate, complication rate and KPS scores were compared with control group undergoing routine operation (n = 27). 3D stereoscopic VR images in accordance with reality were reconstructed for 41 cases. As compared with control group,VR preoperative plan could shorten operative duration and reduce complication rate (P < 0.05). However, there was no improvement in total resection rate or KPS score (P > 0.50). VR technique of Dextroscope system offers comprehe
