Gamma knife surgery for refractory insular cortex epilepsy.

Background: Resection of the epileptogenic insular cortex is surgically challenging. We sought to evaluate the potential of Gamma Knife surgery (GKS) for the treatment of pharmacoresistant insular cortex epilepsy (ICE) in patients who underwent GKS between 2005 and 2010. Adverse events and effects on seizure frequency were assessed.
