| Stereo EEG | Surgery | Follow up | Engel class | |||
|---|---|---|---|---|---|---|
| Interictal | Ictal (EZ) | Involved structures | Type | |||
| ant, anterior; EZ, epileptogenic zone; inf, inferior; int, internal; L, left; lat, lateral; R, right. | ||||||
| Case 1 | L temporal (pole, amygdala, hippocampus, T1 → T4) | Corticectomy + complete lesionectomy | 2 y 11 m | Ia | ||
| Case 2 | R temporal (pole; ant T1; ant-mid T2, T3, T4; mesial) | Corticectomy + complete lesionectomy | 3 y 1 m | Ia | ||
| Case 3 | R temporal (polar, basal and lateral; ant hippocampus) | Corticectomy + complete lesionectomy | 5 y 4 m | Ia | ||
| Case 4 | L triangular and opercular part of F3 | Corticectomy + incomplete lesionectomy | 2 y 11 m | IV | ||
| Case 5 | Lesional zone: orbital and dorsal F2/F3 | Widespread frontal, mesial and lateral | L frontal (polar, orbital and dorsal area) | Corticectomy + complete lesionectomy | 3 y 8 m | IV |
| Irritative zone: orbital, F2, F3, ant and medium cingulated gyrus | ||||||
| Case 6 | Lesional zone: gyrus rectus, int and lat F1, mid ant F2 | Global explored zone except: precentral gyrus, posterior F1 and mesial frontal cortex | L frontal (lateral and mesial polar, basal and dorsal F1, F2, F3) | Corticectomy + complete lesionectomy | 2 y 1 m | Ia |
| Irritative zone: int and mid F2, orbital gyrus | ||||||
| Case 7 | Lesional zone: T2, T3, T4, mid and inf occipital gyrus | Lesion + cuneus and fusiform gyrus, T3, T4, posterior hippocampus | R temporo-occipital (mesial, basal and lateral) | Corticectomy + incomplete lesionectomy | 3 y 7 m | Ia |
| Irritative zone: T1, T2, mid T4, fusiform gyrus, hippocampus | ||||||
| Case 8 | Lesional zone: widespread | Widespread | R fronto-parieto-temporal | Second intervention: incomplete lesionectomy | 5 y 10 m | IId |
| Irritative zone: widespread | ||||||
| Case 9 | Lesional zone: orbital, dorsal F2, mesial F1 | F2-F3 sulcus, F2, anterior cingular gyrus | L frontal (lateral) | Corticectomy | 2 y 4 m | Ia |
| Irritative zone: F2-F3 sulcus, dorsal F2, precentral gyrus | ||||||
