Combined Stereoelectroencephalography (SEEG) and Laser Ablation

Combined Stereoelectroencephalography (SEEG) and Laser Ablation

If you have epilepsy and epilepsy medications are not effective enough to control your seizures, you’re not alone. In fact, almost one-third of patients who suffer from epilepsy experience this issue. If you’ve been taking medications with poor results, your doctor may recommend a procedure called a combined stereoelectroencephalography (SEEG) and laser ablation. This minimally invasive procedure can help you achieve a seizure-free outcome.

Minimally invasive approaches are the newest surgical innovation in epilepsy surgery. SEEG is a surgical procedure to place electrodes within the brain to precisely identify seizure-producing brain areas with minimal discomfort to the patient. In the SEEG surgical procedure, electrodes are placed in targeted brain areas through small 2mm pinholes while the patient is under anesthesia. That allows seizures to be recorded directly from the brain. Once the SEEG procedure reveals the abnormal brain areas producing epilepsy, the patient will undergo a second surgery to remove those pathological brain areas and render the patient free of disabling seizures.

By combining this approach for identifying the seizure-producing zone with other minimally invasive laser-based surgery, like  laser ablation, to disable seizure-producing areas of the brain, it is even possible to achieve a seizure-free outcome without having to undergo a bigger surgery involving craniotomy.
