Surgical removal of seizure-producing areas of the brain has been an accepted form of treatment for over 50 years when medicines fail to prevent seizures. However, because of new surgical techniques and new ways of identifying areas to be removed, more of these operations are being done now than ever before, and with greater success. Surgery can be performed on both children and adults. However, it is not a suitable treatment for everyone who has epilepsy, or for everyone with poor seizure control.
