Gamma knife radiosurgery for callosotomy in children with drug-resistant epilepsy.

Objectives: Gamma knife radiosurgery as a noninvasive procedure is increasingly used as a treatment option in patients with intractable seizures. We investigated efficacy and safety of gamma knife radiosurgery (GKRS) for callosotomy in children.

Materials And Methods: Between 2000 and 2004 three children between 4 and 14 years (mean 8 years) underwent radiosurgical callosotomy.
