Surgical techniques for relief from seizures1
Surgery for the relief of seizures is a well-known technique since the early 1930s; however, only approximately 250 procedures are done for the relief of epilepsy each year. Various techniques have been developed which include hemispherectomy, stereotactic ablations, corticectomy and lobectomy, most often of the temporal lobe and a section of the corpus callosum. Recent advances have been in the development of techniques to isolate the seizure focus and thereby enhance its definition for surgery. The authors present their format for this, and show examples of subdural electrodes in place. An analysis of the data is included.
