LESIONECTOMY IN INDIA
A lesionectomy is an operation to remove a lesion — a damaged or abnormally functioning area — in the brain. Brain lesions include tumors (masses of cells), scars from a head injury or infection, abnormal blood vessels and hematomas (swellings filled with blood).
A lesion causes seizures (is the seizure focus) in about 20% to 30% of people with epilepsy that do not improve after taking medication (intractable or refractory epilepsy). It is not known for certain if the lesion itself triggers the seizures, or if the seizures result from irritation to the brain tissue surrounding the lesion. For this reason, surgery may also include the removal of a small rim of brain tissue around the lesion, called lesionectomy plus corticectomy.
Who Can Have a Lesionectomy ?
Surgeons generally only perform lesionectomies on people who have abnormal lesions on the brain that are the identified source of seizures.
Lesionectomy may be an epilepsy surgery option for those who : -
- Have seizures that are localized to that lesion and that area of the brain
- Have lesions in an area of the brain that can be easily removed with little or no damage to brain function
- Have seizures that can’t be managed with epilepsy medications, which have been tried for at least two years prior to considering surgery
- Have lesions that need to be removed anyway, to prevent further complications such as bleeding or growth of a tumor

Lesionectomy Success Rates in India
Lesionectomy for lesions in the temporal lobe offer the best results, showing significant improvement in more than 80 percent of people who have this surgery. Many of those people don’t have any more seizures following lesionectomy.
How much of the lesion is removed is another factor in determining how successful the surgery is. The more of the lesion that’s removed, the better – people who only have a portion of a lesion removed do not see as great a benefit in seizure reduction as those who lose the entire lesion.
