The aim of this study was to determine the success rate of sEEG in locating the epileptogenic zone (EZ) in patients with pharmaco-resistant epilepsy. Secondary objectives were to analyze sEEG-related morbidity and outcomes for post-sEEG thermocoagulation and cortical resection. ⋯ Our findings suggest that sEEG is an effective technique for EZ location in patients with drug-resistant epilepsy. sEEG was contributive in up to 92% of patients, allowing thermocoagulation and/or surgical resection that resulted in seizure-freedom in two-thirds and seizure-reduction in one-third of cases. This study highlights the need for strict selection of implantation candidates, with strong initial hypothesis as to EZ location.
