Challenges in Intraoperative Corticography in epilepsy

Corticography during surgery is a relatively new method, which can be used to improve surgical outcomes if selected and appropriately performed. Besides recording and identifying seizure focuses, corticography is also required in the brain mapping process. This issue is also important during awakening craniotomy and can prevent false interpretations in mapping of eloquent areas including languag corteex and subcortex areas. However, there is no consensus on its effectiveness and usefulness. Depending on the underlying pathology, its usefulness may vary. Sometimes technical problems also interfere with standard corticography. This article describes how to conduct corticography during surgery and its problems and how they are managed, as well as their indications and existing discrepancies.
