Implication
Observational study demonstrates that intraoperative brain mapping optimizes tumor resection and seizure control in pediatric patients, indicating its safety and utility near eloquent cortex.
Key Points
- To evaluate the efficacy and safety of intraoperative brain mapping for optimizing tumor resection, preserving functional cortex, and eliminating seizure foci in pediatric brain tumor patients.
- Applied direct cortical and subcortical stimulation alongside electrocorticography during resective surgery in children with supratentorial brain tumors.
- Identified and localized language cortex, sensorimotor pathways, and epileptogenic zones relative to the tumor nidus.
- Brain mapping permitted maximal tumor resection, reduced neurological morbidity, and successfully eradicated epileptogenic zones situated adjacent to the tumor.
- Language cortex localization displayed substantial individual variability that could not be reliably predicted by preoperative radiological or neurological assessments.
