Epilepsy surgery is any type of 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.
- Resections are surgeries which cut out part of the brain
- Disconnections are surgeries which cut the fibers from areas of brain cells, called neurons, so that they cannot communicate seizures to other parts of the brain
- Destructive surgeries may destroy a small or large part of the brain with heat from a laser, radiation, sound, or by preventing blood flow
- Stimulative surgeries, more commonly called neuromodulation, are surgeries where part of the brain is stimulated usually through thin wires that are placed in different parts of the brain or on the vagus nerve in the neck.
In this webinar from our awareness campaign “Let’s Talk About Epilepsy Surgery,” Dr. Sandi Lam, Division Head of the Pediatric Neurosurgery Program at Lurie Children’s Hospital of Chicago joins the conversation by providing an overview of the many different epilepsy surgeries used to treat drug-resistant seizures in children. It’s a great place to start if you want to understand epilepsy surgery.
Curative surgery
Many surgeries are categorized as curative. This means that the goal of the surgery is to stop the seizures completely.
These surgeries are:
- Laser ablation
- Lesionectomy
- Lobectomy
- Hemispheric surgeries
- Amygdalohippocampectomy
- Hippocampal transection
- Posterior quadrant resection or disconnection (also known as temporoparietaloccipital disconnection or TPO)
- Radiofrequency ablation
- Stereotactic radiosurgery
- Interstitial radiosurgery
Whether the surgery stops the seizures depends on many factors, including the type of surgery, the cause of the seizures, how long the child has been having seizures, and whether other parts of the brain are developing normally.
Palliative surgery
Some surgeries are palliative. This means that the goal of surgery is to reduce the number of seizures your child is having. Usually, these surgeries will not stop seizures completely.
