About Epilepsy Surgery

Epilepsy surgery is any type of brain surgery where parts of the brain are removed, disconnected, destroyed, or stimulated to stop seizures. There are many different types of epilepsy surgeries. Which procedure is used depends upon the type of seizures presented, where they are localized in the brain and the training and experience of the neurosurgeon.

Curative surgery

The purpose of these procedures is to stop seizures completely. A small number of those with LGS may qualify for these types of surgery. Resections are surgeries that remove part of the brain, while a disconnection is a procedure that disconnects part of the brain while leaving the rest of the brain intact. Other surgeries may destroy a small or large part of the brain with heat (laser), radiation, or by preventing blood flow. They include:


Neuromodulation is a type of technology that acts directly upon nerves. A device is implanted in a person, and this alters nerve activity by delivering electrical impulses directly to specific nerves. The most common types of neuromodulation used in LGS are Vagus Nerve Stimulation (VNS), Responsive Neurostimulation (RNS), and Deep Brain Stimulation (DBS). All of these require some type of surgery to implant the device.

Palliative surgery

There are other procedures that are not intended to stop the seizures completely but instead aim to stop the seizures after they begin or reduce the number of seizures. These are known as palliative procedures. They include:
