Fig. 1: The differences between FCD types I and II in lesion location, extent, surgical approach and prognosis.

a The proportion of lesion location, extent, and surgical approach in FCD type I and its pathological subtypes. b The proportion of lesion location, extent, and surgical approach in FCD type II and its pathological subtypes. c Recurrence-remission proportions for FCD type I and type II following surgery. d The Kaplan-Meier curve of FCD type I and type II. The difference in surgical prognosis between these two pathology types was statistically significant (p < 0.05). e Recurrence-remission rates of postoperative seizure in 4 pathological subtypes. f The Kaplan-Meier curve of 4 pathological subtypes. The difference in surgical prognosis among these pathological types was statistically significant (p < 0.05). Abbreviations: FCD, focal cortical dysplasia.
