Electrocorticography (ECOG) aids epilepsy surgery by localizing tissue and predicting outcomes. However, evidence supporting its effectiveness in guiding resection and predicting success remains limited, especially in pediatric cases.

Area of Science:

  • Neurosurgery
  • Epileptology
  • Neurophysiology

Background:

  • Electrocorticography (ECOG) is crucial for surgical management of medically refractory epilepsy.
  • ECOG aids in localizing epileptogenic tissue, mapping cortical functions, and predicting surgical success.
  • Limited evidence exists to validate ECOG's effectiveness in these roles.

Purpose of the Study:

  • To review the effectiveness of ECOG in surgical epilepsy management.
  • To assess ECOG's role in pre-resection localization and post-resection outcome prediction.
  • To examine ECOG application in pediatric epilepsy surgery.

Main Methods:

  • Computerized medical literature search.
  • Review of retrospective studies on ECOG in epilepsy surgery.

  • Analysis of ECOG's utility in temporal and extra-temporal resections (lesional and nonlesional).

    • Main Results:

    • Most studies focused on adult patients and were retrospective.
    • Evidence supporting pre-resection ECOG for guiding resection extent was limited.
    • Post-resection ECOG's predictive value for surgical outcomes was also restricted.

    Conclusions:

    • The effectiveness of ECOG in guiding epilepsy surgery and predicting outcomes requires further robust evidence.
    • More prospective studies are needed to establish ECOG's definitive role.
    • ECOG application in children presents unique challenges due to age-related limitations.
