For patients who had a second surgery, time to seizure and postoperative follow-up duration are measured from the time of the second surgery.

Epi duration, duration of the epilepsy; MTS, ipsilateral mesial temporal lobe sclerosis; PET, ipsilateral temporal hypometabolism on positron emission tomography; non-TL EEG, non-temporal lobe interictal EEG findings; IRSA, interictal regional slow activity; Non-lat or contra sz, non-lateralizing or contra-lateralizing seizure onset; side, side of surgery; Post-op, post-op follow-up months; time to sz, time from surgery to first postoperative seizure; ASM; anti-seizure medications; 2nd surg, second surgery.

^*Patient 4 had a seizure 11 months after the first ablation and was seizure free at 52 months after the second ablation.

^#Patient 9 had a seizure 36 months after the first ablation and was seizure free at 28 months after the second ablation.

^@Patient 14 had a seizure 7 months after the first ablation and was seizure free at 38 months after the second ablation.

^∧Patient 20 had a seizure 1 month after the first ablation and was seizure free at 39 months after the second ablation.
