nTMS for Motor Mapping of Rolandic Lesions

To compare presurgical motor mapping by navigated transcranial magnetic stimulation for surgery (nTMS) of rolandic lesions to surgery with mapping without implementing these data into neuronavigation as control. Primary objective: Permanently new postoperative deficit is lower when the preoperative motor mapping is available to the surgeon

Experimental intervention: presurgical motor mapping by navigated transcranial magnetic stimulation and fusion with intraoperative neuronavigation Control intervention: presurgical motor mapping by navigated transcranial magnetic stimulation without access of the surgeon to this data Follow-up per patient: 6 months Duration of intervention per patient: 45 minutes
