What is the success rate of surgery for epilepsy?

The success rate of surgery for epilepsy is about 80-90%, but it is important to note that there is a gap between whether surgery is needed and what kind of surgery is done. Theoretically, about 75% of epilepsy can be controlled very clearly with medication, and although sometimes more medication needs to be taken, it can basically be controlled very well. Then there is epilepsy focal resection surgery, which is a very classical surgery for superficial epileptogenic foci, with an efficiency of about 80% after surgery, but not all of them are effective. Nowadays, as technology advances, there is another way to implant bipolar electrocoagulation directly into the brain, which is called electrode implantation.
