Surgical treatment
Surgical treatment can be an option for epilepsy when an underlying brain abnormality, such as a benign tumor or an area of scar tissue (e.g. hippocampal sclerosis) can be identified. The abnormality must be removable by a neurosurgeon.
Surgery is usually only offered to patients when their epilepsy has not been controlled by adequate attempts with multiple medications. Before surgery is offered, the medical team conducts many tests to assess whether removal of brain tissue will result in unacceptable problems with memory, vision, language or movement, which are controlled by different parts of the brain. These tests usually include a neuropsychological evaluation, which sometimes includes an intracarotid sodium amobarbital test (Wada test) - although this invasive procedure is being replaced by non-invasive functional MRI in many centres. Resective surgery, as opposed to palliative, successfully eliminates or significantly reduces seizures in about 50-90% of the patients who undergo it (the exact percentage depends on the particulars of the case and surgeon in question.) Many patients decide not to undergo surgery owing to fear or the uncertainty of having a brain operation.
The most common form of resective surgical treatment for epilepsy is to remove the front part of either the right or left temporal lobe. A study of 48 patients who underwent this operation, anterior temporal lobectomy, between 1965 and 1974 determined the long-term success of the procedure. Of the 48 patients, 21 had had no seizures that caused loss of consciousness since the operation. Three others had been free of seizures for at least 19 years. The rest had either never been completely free of seizures or had died between the time of the surgery and commencement of the study.[10]
Palliative surgery for epilepsy is intended to reduce the frequency or severity of seizures. Examples are callosotomy or commissurotomy to prevent seizures from generalizing (spreading to involve the entire brain), which results in a loss of consciousness. This procedure can therefore prevent injury due to the person falling to the ground after losing consciousness. It is performed only when the seizures cannot be controlled by other means. Resective surgery can be considered palliative if it is undertaken with the expectation that it will reduce but not eliminate seizures.
Hemispherectomy is a drastic operation in which most or all of one half of the cerebral cortex is removed. It is reserved for people suffering from the most catastrophic epilepsies, such as those due to Rasmussen syndrome. If the surgery is performed on very young patients (2-5 years old), the remaining hemisphere may acquire some rudimentary motor control of the ipsilateral body; in older patients, paralysis results on the side of the body opposite to the part of the brain that was removed. Because of these and other side effects it is usually reserved for patients who have exhausted other treatment options.
