Surgery to remove a seizure-producing area of the brain is called epilepsy surgery. The most likely candidates for epilepsy surgery are those who suffer seizures at a specific location in the brain. Surgery is recommended when at least two anti-seizure medications have failed to prevent seizures.
Patients must undergo several preoperative tests to determine whether epilepsy surgery is right for them and how it is performed.
Epilepsy surgery: When is it necessary?
It is generally recommended to consider an epilepsy surgery in the following situations:
There is no control over seizures with antiseizure medication. Drug-resistant epilepsy refers to epilepsy in which at least two drugs have not successfully controlled seizures.
The side effects of antiseizure medications are too much for the patient to handle.
Ketogenic diets like the Atkins diet haven't controlled seizures.
The seizures have a high frequency, severity, and debilitating nature.
There may also be a need for surgery if non-epileptic conditions, such as an arteriovenous malformation or a brain tumour, cause such seizures. Visit our Epilepsy Surgery Treatment Hospital in Yeshwanthpur to know more about the need for surgery.
Epilepsy Surgery procedure
A section of the patient’s skull will be removed during the operation, for which their hair must be trimmed short or shaved to prevent infection. Intravenous access is administered to the patient, in which fluids, anaesthetic drugs, or other medications are delivered through a small, flexible tube placed in their vein.
A monitoring device will measure heart rate, blood pressure, and oxygen levels throughout the surgery. As part of the operation, an EEG monitor may record the patient’s brain waves to locate better the part of their brain that begins seizures.
General anaesthesia is usually used for epilepsy surgery to make the patient unconscious during the procedure. Some surgeons arouse patients during operations to test which parts of their brain control movement and language. The pain would be controlled by medication in such cases.
It depends on the type of surgery and how large a window the surgeon makes in the skull. An implant is used for healing after surgery to replace the window of bone.
As the patient wakes up from anaesthesia, they are closely monitored during recovery. A hospital intensive care unit may be needed for the first night following surgery, and a hospital stay of three to four days is typical for epilepsy surgeries.
It is usually painful and swollen when the patient awakens post-surgery. Most people need narcotics for the first few days to cope with the pain, and ice packs may also be helpful. Swelling and pain in the days and weeks following surgery usually subside.
Approximately one to three months will pass before the patient can return to work or school. After epilepsy surgery, they should rest and relax for a few weeks, then gradually return to normal activities.
In the event a stroke or loss of speech was to occur during the surgery, the patient would not need intensive rehabilitation.
Different types of epilepsy surgery result in different outcomes. Medication is expected to control seizures.
About two-thirds of people who undergo temporal lobe resections achieve seizure-free outcomes. Studies have shown that if individuals are seizure-free at two years after temporal lobe surgery - with medication - they are likely to be seizure-free at three years. In five years and ten years, 95% of people who haven't had a seizure in two years are likely to remain seizure-free.
