Epilepsy surgery
Epilepsy surgery is used to treat seizures, which could not be controlled using two or more Anti-seizure medications.
Types of Epilepsy Surgery
- Surgical resection: Removing the part of your brain where the seizures start or removing the abnormal brain tissue that’s causing the seizures. Examples include lesionectomy, lobectomy , multilobar resection and hemispherectomy.
- Surgical disconnection: Disconnecting parts of your brain or areas where nerve cells communicate to stop the spread of seizures. Examples include corpus callosotomy and multiple subpial transection.
- Laser interstitial thermal therapy: Using MRI scans to guide a small laser probe. This technique is used to destroy nerve cells at the seizure site. It’s less invasive than other types of open surgery.
- Neuromodulation (implanted devices): Implanting a device and electrodes that send electrical signals to block or disrupt seizure activity at its source. Examples include vagus nerve stimulation, responsive neurostimulation and deep brain stimulation
- Implantation of electrodes: Your provider may need to collect data by recording signals directly from your brain. They’ll do this by carefully implanting electrodes into (or on the surface of) your brain. This information helps your surgeon decide upon a good surgical strategy that’s tailored toward the treatment of your seizures. Examples include stereoelectroencephalography and subdural grid implantation.
