Introduction: Epilepsy surgery is a standard of care in the treatment of medically intractable epilepsy. Twenty five percent of patients with intractable epilepsy in childhood can be candidates for epilepsy surgery. Corpus callosotomy is a surgical treatment option for patients with potentially injurious drop attacks and disabling generalized seizures. Postoperative improvement of cognition and speech are important gains after epilepsy surgery particularly during childhood. The aim of this study is to evaluate the outcome of corpus callosotomy for the treatment of childhood onset medically intractable epilepsy in a developing pediatric epilepsy surgery center. Method: We report 16 patients who underwent two thirds anterior corpus callosotomy for treatment of refractory seizures in childhood. Results: All patients had drop attacks or multiple types of seizures, yet some showed focal onset with secondary generalization on electroencephalogram (EEG). One patient was seizure free (class 1 outcome), five had class 2A outcome, five had class 2B outcome, and five had class 3 outcome. Overall 11/16 (69%) of our patients improved significantly after anterior callosotomy. Conclusion: Corpus callosotomy remains to be a fairly good choice of surgical treatment for childhood onset medically intractable epilepsy in selected patients.
