ABSTRACT
Objective To explore surgical treatment of gliomas involving the motor eloquent area. Methods Twelve cases of gliomas involving precentral gyrus were underwent awake surgery procedures assis- ted with neuronavigation and brain functional mapping by cortical electrical stimulation.Results Eleven ca- ses acquired accurate location of both lesions and eloquent areas by neuronavigation and direct cortical stimula- tion.7 cases of motor cortices and 2 cases of motor speech centers were confirmed during the operation.Re- section,verified by postoperative MRI,was total in 8 cases (66.7%) and subtotal in 4 patients.Histological examination revealed an infiltrative glioma in all cases (8 low grade astrocytomas,2 high grade astrocytomas and 2 glioblastoma).Four patients had no postoperative deficit,while the other 8 patients were impaired, with,in all cases except one,complete recovery in 7 days to one month.Conclusion Direct cortical elec- trical stimulations and awake surgery offer a reliable,precise and safe method,allowing functional mapping es- pecially useful in case of infiltrative cerebral tumors in eloquent areas.This technique allows improvement in the quality of tumoral resection and concurrently a minimization of the risk of definitive postoperative neurologi- cal deficit.
