Electrophysiological mapping improves surgical outcomes in patients with refractory focal epilepsy, indicating better quality of life post-surgery.

The goal is to enhance surgical outcomes for patients with refractory focal epilepsy through precise intraoperative localization techniques.
Evaluated seizure patterns and performed comprehensive clinical assessment before surgery.
Utilized preoperative MRI and intraoperative electrocorticography for mapping the epilepsy focus.
Conducted resections guided by neuronavigation and cortical reconstruction.
The patient experienced no neurological deficits post-surgery and seizure-free outcomes.
Histopathological analysis illustrated neuronal depopulation and chronic injuries in the remaining tissue.
Identified the importance of accurate lesion mapping and intraoperative guidance in epilepsy surgeries.
