Area of Science:

  • Neurosurgery
  • Neurophysiology
  • Medical Imaging

Background:

  • Intraoperative neuromonitoring (IOM) is a critical perioperative tool in neurosurgery.
  • It complements advanced techniques like stealth navigation and fluorescence microscopy.
  • IOM provides real-time functional information during surgical procedures.

Purpose of the Study:

  • To review the role and application of intraoperative neuromonitoring in brain surgery.
  • To highlight its ability to map eloquent brain areas.
  • To emphasize its contribution to optimizing surgical resection and preserving neurological function.

Main Methods:

  • Electrical stimulation of cerebral cortex and subcortical areas for mapping.
  • Real-time identification of eloquent brain regions.
  • Functional guidance during both awake and asleep neurosurgery.

Main Results:

  • Successful cortical and subcortical mapping.
  • Real-time identification of eloquent brain areas.
  • Facilitation of functional guidance throughout neurosurgery.

Conclusions:

  • Intraoperative neuromonitoring is essential for functional guidance in brain surgery.
  • It enables precise identification of critical brain areas.
  • The method optimizes the extent of resection while preserving neurological function.
