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.
