Abstract
Background
Stereoelectroencephalography-guided radiofrequency thermocoagulation (SEEG-RFTC) is a minimally invasive therapy for drug-resistant focal epilepsy. However, the relationship between specific seizure-onset patterns (SOPs), particularly low-voltage fast activity (LVFA), and postoperative scalp EEG normalization remains inadequately characterized. This study investigates whether LVFA predicts RFTC efficacy and whether postoperative EEG serves as an objective complement to clinical outcome measures.
