Age (years) at time of operation ranged from 3 to 20 years (M = 10.89, SD = 4.76 years). Patients with complete postsurgical seizure freedom (Engel Score = 1) were designated as “Sz-Free” (n = 9) while patients exhibiting recurrent seizures (Engel Score ≥2) were assigned to the “Sz-Persist” group (n = 9). p values for group comparisons were computed using Wilcoxon rank sum tests. L, left; R, right; F, frontal; T, temporal; Hemi, hemisphere; SOZ, seizure onset zone; LE, lesional; NL, non-lesional.
