Neuronavigation-assisted glioma surgery

Objective To evaluate the application of the neuronavigation system in gliomassurgery. Methods We used the BrainLAB VV2 navigationr system in 62 patients with gliomas in different region of hemisphere. The value of this system for glioma resection was assessed, and the advantages and cautions for application were discussed. Results Of our cases, the mean registration error was 1.2±0.5mm. According to the imaging data, total lesion removals were achieved in 35 patients (56.5%). The clinic status of all patients showed improvement, and the critical functions, e.g. motor, were not significantly affected. There were no complications attributed to the use of this system. Only three patients relapsed during the short-time followup. Conclusion The neuronavigation system is reliable and accurate in surgical treatment for gliomas. It increases radicality in glioma resection without injuring the critical functions.
