Objective To investigate clinical features and surgical outcome in children with frontal lobe epilepsy by evaluating the correlation between the predictive factors and seizure freedom. Methods 18 children who underwent frontal lobe epileptogenic resection in the Epilepsy Center of the Children's Hospital of Fudan University between January 2017 and December 2019 with a minimum follow up of 2 year were analyzed retrospectively. Each patient was evaluated with detailed data to predict postsurgical seizure freedom by analysis of variance. Results Of the 18 patients, there were 11 males and 7 females, the age at surgery ranged from 21 months to 11 years old (6.8±2.73) and the duration of seizures was from 1 month to 9 years. 17 patients had focal seizures, while 1 had generalized epileptic spasm. In scalp EEG, interictal and initial ictal discharges were frontal in 11 and 9 cases, respectively. MRI was indicative of FCD in 10 cases, tumor in 2, tuberous sclerosis and gliosis lesion in 1 case each. 4 patients were MRI negative. 11 patients underwent epileptogenic lesion resections directly and 7 cases received depth electrodes implantation and underwent stereo-electroencephalography to localize epileptogenic zone. At follow-up of 2 years, 14 (77.8%) patients remained seizure-free (Engel Ⅰ), 1 (5.6%) had marked seizure reduction (Engel Ⅱ), 2 (11.0%) showed minor improvement (Engel Ⅲ), and only 1 (5.6%) showed no response (Engel Ⅳ). About predictors of seizure recurrence, there were no significant differences in gender, age at surgery, age of seizure onset, duration of epilepsy, lateralization of epileptogenic zone, positive MRI findings, interictal and ictal discharge, etiology, intellectual development and stereo-electroencephalography implantation, while significantly higher rates of seizure freedom correlated with complete the resection of the epileptogenic zone. Conclusions Focal cortical dysplasia is the most common cause in childhood with frontal lobe epilepsy and complete resection of the epileptogenic zone can lead to good seizure control outcome.
