Current technological progress in neurosurgery and its impact on surgical treatment of glioma brain tumours

Brain gliomas are characterized by infiltrative growth, with possible finding of functional brain tissue within the tumor. Intraoperatively are glioma borders often indistinguishable from surrounding brain. Eloquent areas can be damaged during surgical removal of tumors near or within these areas. Therefore, in addition to preoperative identification of cortical and subcortical eloquent areas, meticulous microsurgical technique, neuronavigation, intraoperative imaging, neuromonitoring and awake surgery are necessary. Using these methods, satisfactory and safe resection of tumors previosly considered as unresectable is possible.

Keywords: Glioma, eloquent areas, neuromonitoring, awake surgery.
