Resection of tumors within and near to the primary Sensory-Motor cortex using Phase reversal Cortical mapping and bipolar stimulation

Objective Brain mapping techniques allow one to effectively approach tumors involving the primary sensory-motor cortex and nearby area (M1). Tumor resectability maintenance of patient integrity depend on ability successfully identify motor tracts during resection by choosing most appropriate neurophysiological paradigm for mapping. Mapping with a high frequency (HF) stimulation technique has emerged as efficient tool because its versatility in different clinical settings. At present, few data are available use HF removal predominantly M1. Methods The authors have analysed series 6 patients brain within M1, reviewing guide. protocols adopted resections were described correlated patients’ tumor imaging features. Feasibility mapping, extent resection, function assessment used evaluate oncological functional outcome be selected parameters guiding resection. study aimed define protocol guide each condition. gliomas
