Aggressive resection of intracranial gliomas, which has a positive impact on prognosis, is unfortunately associated with an increased risk of neurological complications. To preserve brain function and avoid major postoperative morbidity, various intraoperative neurophysiological monitoring methods have been introduced in clinical practice. Specifically, it is critical to understand and master the utility of monitoring by somatosensory evoked potential and motor evoked potential (MEP). Functional mapping during awake craniotomy can be used to detect individual eloquent tissues of motor function and to observe patient’s voluntary movement with an aim of preventing unexpected deficits and promote extensive resection. Corticocortical evoked potential (CCEP) is a novel method useful for functional monitoring of language-related fibers such as arcuate fiber.
Finally, the future monitoring we propose will support decision making of tumor removal by integrating information from various medical devices and positional information of navigation in time synchronization.
