Trial Outcomes & Findings for High Frequency Oscillation in Pediatric Epilepsy Surgery (NCT NCT03790280)
NCT ID: NCT03790280
Last Updated: 2023-09-01
Results Overview
The primary outcome measure is the number of patients seizure-free after surgery in the treatment arm of combined HFO and standard of care, compared to the number of patients seizure-free in the control arm of standard of care alone, at 1 year after surgery.

Standard of Care PLUS HFO
Surgery is tailored by HFOs and standard ECoG interpretation (spikes on intra-operative ECoG or seizure onset on extra-operative ECoG) (arm 1).
HFO analysis: We hypothesize that the strategy of incorporating HFO data to a standard ECoG-guided resection in pediatric epilepsy surgery will result in improved postoperative seizure outcome than the traditional approach.

Standard of Care
Surgery is tailored by standard ECoG alone (arm 2).
