Department of Neurology, University of Munich, Germany

Subdural electrodes are useful in selected patients with cortical dysplasia for planning resective epilepsy surgery. Their potential risks have to be balanced against the diagnostic yield and expected benefit of epilepsy surgery for the patient. Recent advances in imaging techniques now allow more accurate placement of the subdural electrodes and also limit the number required.
