There are various methods of epilepsy surgery, which can be divided into 3 types according to broad categories. The first is lesion excision. This is also the most effective radical procedure. The first is focal epilepsy, which is broadly divided into temporal lobe resection of the epileptogenic foci and extratemporal lobe resection of the epileptogenic foci, where only localized lesions are removed. Second, some children have extensive intracranial lesions involving the entire cerebral hemisphere, some of which can be removed. It is important to note that for these children, the function of the affected and contralateral hemispheres should be evaluated preoperatively. If the function of the affected side is poor and the corresponding function has been partially or mostly transferred to the contralateral hemisphere, especially if the patient is young and the brain is highly plastic, the surgery can achieve the desired result. If the affected side of the brain assumes some of the important functions and the contralateral brain cannot compensate for them, hemispherectomy on the affected side cannot be done. The second is dissection surgery, in which the connection between the two cerebral hemispheres is severed so that abnormal discharges on one side cannot be transmitted to the other side. This approach is indicated in cases where the intracranial lesion is extensive, or where the lesion is located in a known functional area and removal would affect the patient’s ability to behave normally. Disconnection surgery can reduce and mitigate seizures and provide some relief from symptoms. The third is vagus nerve magnetic stimulation, which is mainly for children with abnormal discharges on both sides of the brain. A vagus nerve stimulator is surgically embedded under the skin and electrodes are implanted in the vagus nerve that is wrapped around the left side of the neck, using different stimulation parameters and intermittent stimulation to achieve seizure control. This procedure is relatively simple and can be installed in almost all patients, but the equipment is expensive, costing approximately $180,000 for the entire procedure and equipment.
