神经内镜经蝶手术三维可透视化模型的构建及术前规划作用的研究
Construction of three-dimensional perspective model of endoscopic transs-phenoidal surgery and the role in surgical planning
摘要
Abstract
Objective:Virtual reality technology was applied to build three-dimensional perspective model of transsphenoidal surgery to explore the role in application value in endoscopic transsphenoidal surgical planning. Methods:A total of 36 patients with sellar tumor diagnosed by MRI were included in the study. The CT,MRI,MRA data of each patient was collected preoperatively. Then Vitreafx Imaging Data Workstations was used to bulid the three-dimensional perspective model of sellar region. Anatomical structures re-lated to surgical approach and spatial positional relationships with tumor were observed and surgical procedure was simulated. Finally the simulated endoscopic operation and actual endoscopic surgery process was compared. Results:Three-dimensional perspective model of each patient was established sucessfully and the anatomic location like bone,sphenoid sinus interval,cervical internal carotid arterial eminence,bulges of optic nerve canal,optic nerve and tumors as well as the adjacent relationships of markers with tumors were clearly displayed. Surgical planning and surgical approach were formulated successfully,and the actual endoscopic surgery process was consist-ent with the simulated endoscopic operation. Conclusion:Three-dimensional perspective model has high authenticity and it provides a clear three-dimensional anatomical information and effective assistance to the pre-surgery planning. The simulated endoscopic operation under the guidance of three-dimensional perspective model before surgery can reduce risks of surgery and improve surgical accuracy and safety.关键词
