BACKGROUND AND PURPOSE: Temporal lobe epilepsy (TLE) encompasses 10-20% of the cases of intractable epilepsy in pediatric patients. Mesial temporal sclerosis (MTS) can still be encountered in adolescent patients, but is rare in children under 5 years of age. In this paper we report on the surgical outcome of a series of TLE patients ranging in age from 1 to 18 years at the time of operation. PATIENTS AND METHODS: Thirty-five patients (37 surgeries) with medically intractable TLE were operated upon between January 1996 and December 2002. The following variables were analyzed: age at surgery, age at epilepsy onset, history of an initial precipitating injury, etiology, seizure semiology, interictal and ictal EEG findings, surgical complications, and post-surgical seizure outcome. RESULTS: There were 68.6% females and 31.3% males, and complex partial seizures (CPS) occurred in 86.5%. The most common etiology was MTS (40%) followed by isolated cortical developmental abnormalities (22.9%). In the age group up to 5 years, cortical development abnormalities predominated, and 71% of these children had multifocal interictal EEG. Patients older than 10 years had more frequently MTS (78.6%) and focal temporal interictal EEG abnormalities. Post-surgical seizure outcome showed that 88.5% of patients were in Engel classes I and II. CONCLUSIONS: Adolescents with TLE had clinical features, electrographic findings, and seizure outcome similar to those observed in adult patients. However, younger children up to 5 years of age had distinct ictal semiology and different etiological, electrophysiological and outcome profiles, clearly suggesting that they behave as a special subgroup within the TLE.
