Multiple subpial resections are an alternate type of surgery that is used if seizures begin in a region of the brain that cannot be removed safely. This would include areas in the brain that control speech or movement.
The pia is a delicate membrane that surrounds the surface of the brain. The cuts transections work by interrupting fibers that are thought to be involved in the spread of electrical seizure activity. Sometimes MST are done in combination with a surgical resection when a part of the seizure focus is in a critical region speech or movement of the brain and a complete resection of the seizure focus is not possible.

Laser interstitial thermal therapy is sometimes called laser ablation surgery. During the surgery, a MRI magnetic resonance imaging is used to precisely map out the exact area of the brain to operate on. Laser is then delivered with pinpoint accuracy to this area to eliminate the seizure focus. All of this is done without needing to open the skull, making it a minimally invasive procedure.
This minimally invasive surgery can be effective for drug resistant focal epilepsy due to small lesions. This treatment has been used most commonly in people with temporal lobe epilepsy from mesial temporal sclerosis scar tissue in the temporal lobe. People most appropriate for this type of surgery include. Early data on laser ablation surgery shows more than half of people treated with LITT achieve freedom from seizures.
This type of surgery continues to be carefully studied. A multicenter clinical trial is ongoing to assess the safety and effectiveness of this procedure in individuals with mesial temporal sclerosis. The procedures involve separating the area of seizure onset from the rest of the brain. This typically is reserved for children with very large areas of seizure onset.

The results of these surgical procedures are very good. Corpus callosotomy is usually reserved for people with severe generalized epilepsy meaning seizures involve both sides of the brain who are subject to drop attacks atonic seizures and falls. The procedure involves splitting the main connection pathway between the two cerebral hemispheres sides of the brain. Stereotactic radiosurgery uses many precisely focused radiation beams to treat the area of the brain where seizures begin seizure focus.
There are several different types of stereotactic radiosurgery.

They are considered minimally invasive as the surgeon does not have to open the skull for the procedure. Stereotactic radiosurgery uses 3-D imaging to target high doses of radiation to the seizure focus with minimal impact on the surrounding healthy tissue. Three neurostimulation devices are approved for the treatment of drug resistant epilepsy. In summary, there are several different types of surgery that are available to treat people with drug resistant seizures. Your epilepsy team will discuss what options are possible for you and will help guide you through the proper evaluation and testing prior to making a decision about surgery.
The mission of the Epilepsy Foundation is to lead the fight to overcome the challenges of living with epilepsy and to accelerate therapies to stop seizures, find cures, and save lives.

Removing the seizure focus is the most common type of epilepsy surgery. It is an excellent treatment option for people who have seizures arising from one area of the brain.

The chances of success are highest in people who have an abnormality on MRI magnetic resonance imaging that matches the area where seizures start on EEG electroencephalogram monitoring. Since it involves removing a part of the brain, it is reserved for people whose seizures arise from non critical brain regions. Examples of critical brain regions include areas that control speech, movement, memory, and vision. Temporal Lobe Resection Temporal lobe resection is removing a portion of the temporal lobe of the brain.
Frontal Lobe Resection Frontal lobe resection refers to removing an area in the frontal lobe where seizures begin.
The frontal lobes of the brain control functions like motivation, attention, concentration, organization, planning, mood, and impulse control. People who have frontal lobe seizures may have problems with these functions before surgery. It is important to understand there may also be changes seen in these brain functions after surgery. Although this group continues to have seizures, the majority of people have a large decrease in the number of seizures. A small number of people do not have any improvement in seizure control. Parietal and Occipital Lobe Resection The parietal and occipital lobes are located in the posterior back part of the brain.
Lesionectomy Removing a lesion that causes focal seizures is called a lesionectomy. Multiple Subpial Transections MST Multiple subpial resections are an alternate type of surgery that is used if seizures begin in a region of the brain that cannot be removed safely. Anatomic hemispherectomy involves removing the frontal, parietal, temporal, and occipital lobes on one side of the brain.

Deeper brain structures basal ganglia and thalamus are left in place. This type of hemisphere surgery has higher risk and is usually considered for people with hemimegalencephaly a rare condition where one side of the brain is abnormally larger than the other. Functional hemispherectomy involves removing a smaller area of the affected hemisphere and disconnecting the remaining brain tissue.
This surgery involves less risk but is only helpful in a select group of people. Dizziness is a common side effect of the medications used to treat heart failure.
