Epilepsy Surgery in India
Epilepsy is one of the most common neurologic diseases, present in about 4% of the world's population. The disease can be well controlled with medications alone, but many patients do not respond well to the epileptic medications and thus need surgery to control seizures
Epilepsy surgery is advised to people who have tried at least two epilepsy drugs without success and have seizures originating on the same place of the brain.
Epilepsy surgery removes or isolates the area of brain where seizures originate. If it is an area of the brain which cannot be removed, the surgeon makes incisions to prevent seizures from spreading to other parts of the brain
Why is Epilepsy surgery required?

Types and Techniques for Epilepsy Surgery

This is the most common type of surgery and is highly successful. Medically known as resective surgery ( and popularly known as temporal lobe resection), it entails removal of a portion- a lobe, portion of lobe or the lesion that is causing seizures, about the size of golf ball
Removal of connection between brain hemispheres
Medically known as corpus callosotomy, this type of surgery is usually performed in children who have seizures starting in one hemisphere spreading to the other. The surgery severs the neural connections between the right and left halves of the brain and thus stops seizures from spreading and reduces its severity as well.
Removal of half of the brain
Medically known as hemispherectomy, this is the most radical surgery, which removes the outer layer of the half of the brain. It is done in children with seizures because of damage to one half of the brain, occurring in rare conditions during birth. The chances of recovery are quite good in young children.
