Cortical resections outside the temporal lobe for intractable epilepsy--excluding multilobar resections and hemispherectomy.

The principles underlying such surgery are reviewed, together with details of the necessary investigation, and a review of long term results from the literature. Cortical Resection for epilepsy remains a useful treatment for drug resistant epilepsy when a cortical focus can be identified by neurophysiological or radiological means. Such a resection has a reasonable chance of relieving or ameliorating the epilepsy with only a small chance of producing or worsening any neurological deficit.
