Lesional epilepsy: lesionectomy versus ECoG-guided resection

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

Lesion-related epilepsy, especially that related to cortical dysplasia and low-grade tumors, is one of the most common causes of pediatric focal epilepsy. Although removing the lesion may control the seizures, often, the epileptogenic zone (EZ) is wider than the lesion itself. Many variables may affect the EZ in relation to the lesion, such as the pathology, location, and duration of epilepsy. When operating on children with lesional epilepsy, the added value of tailoring the resection by intraoperative electrocorticography (ioECoG) over a lesionectomy is a matter of debate. In this chapter, we discuss the current evidence for each surgical approach (lesionectomy vs ECoG tailored).
