Background And Introduction: Intraoperative neuromonitoring for eloquent cortical lesions is irreplaceable in present-day neurosurgery.
Objective: We report a novel technique of combining awake craniotomy with direct cortical stimulation of the motor cortex using the NIM nerve monitoring system.
Technique: A 17-year-old boy presenting with focal motor seizures, diagnosed with left perirolandinc cavernoma, underwent awake craniotomy and complete excision under direct cortical stimulation with NIM monopolar stimulator electrode to locate the motor cortex.
