EVALUATING THE EFFICACY OF NEURONAVIGATION IN SURGICAL TREATMENT OF GLIAL TUMORS.

The experience of Medtronic Stealth Station S7 neuronavigation system in surgical treatment of patients with brain tumors is presented in this article. The study included 280 patients in age from 17 to 70 years, 128 women (46.6%), 152 men (53.4%) with tumors of the cerebral hemispheres. Basic topical diagnosis was based on MRI data. Intracerebral tumors were diagnosed in 248 patients, extracerebral in 32. Lesions of the dominant hemisphere of the brain were observed in 146 (52.1%) patients. We operated with navigation technologies. Medtronic Stealth Station S7 neuronavigation system allows to integrate data of preoperative neuroimaging studies and intraoperative information that optimizes the surgical treatment; video monitoring of surgical operations in real time provides control of tumor removal and related dislocational changes. The use of neuronavigation in neurooncology allows to improve tumor resection, to avoid damage of functionally important brain areas and to reduce the risk of postoperative neurological deficit.
