Seizure outcome after corpus callosotomy in a large paediatric series.

Corpus callosotomy is an effective palliative treatment and well tolerated in children. Good outcomes for the first 12 months after surgery were likely to continue. The number of antiepileptic drugs can be significantly reduced after corpus callosotomy. Patients with fewer than three types of seizure had better outcomes. There were fewer injuries from drop attacks after surgery.
