Clinical application of a neuronavigation system in the resection of tumors in deep brain

Objective:To explore the application and superiority of BrainLAB Kolibri navigation system in the resection of tumors in deep brain.Methods:All 17 cases with tumors in deep brain underwent microsurgery assisted with neuronavigation system.The radiological information was uploaded into the neuronavigation system to perform navigation plan.The incision and operative approach were designed by neuronavigation system according to the location of tumors.The operative approach,tumor and important structures around the tumors were orientated accurately by neuronavigation system during microsurgery as well as the resection rate were judged precisely.Results: The tumors were found directly and removed properly in all cases.The tumors were totally removed in 15 patients and subtotally removed in 2 patients.1 patient got paralysis and aphasia transiently post operation,the symptoms alleviated 2 weeks later.1 patient received γ-knife therapy and there was no neurological deficit 3 months after microsurgery.The clinical symptoms in all patients were improved or disappeared.Conclusion:The application of neuronavigation-assisted microsurgery to the tumors in deep brain is helpful to accurate localization of the tumors and important structures around the tumors.The curative effect can be enhanced,the damage of normal brain and the operative complications can be reduced by the neuronavigation-assisted microsurgery in the patients with tumors in deep brain.
