Beyond Resection: Neuromodulation and Minimally Invasive Epilepsy Surgery

Area of Science:

• Neurology
• Neurosurgery

Background:

• Epilepsy is a prevalent neurological disorder with significant patient and healthcare burdens.
• Approximately one-third of epilepsy patients have drug-resistant epilepsy (DRE), making them candidates for surgical interventions.
• Numerous barriers, including patient fear, healthcare disparities, and complex evaluations, limit surgical treatment rates for DRE.

Purpose of the Study:

• To review the role and effectiveness of advanced surgical techniques for drug-resistant epilepsy.
• To discuss minimally invasive surgeries (MIS) and neuromodulation in managing varied epilepsy subtypes.
• To evaluate seizure outcomes and adverse effects associated with these epilepsy surgeries.

Main Methods:

• Review of current literature on epilepsy surgery techniques.
• Analysis of minimally invasive surgical (MIS) methods: Laser Interstitial Thermal Therapy (LITT), RadioFrequency Ablation (RFA), Stereotactic RadioSurgery (SRS).
• Evaluation of neuromodulation techniques: Vagus Nerve Stimulation (VNS), Deep Brain Stimulation (DBS), Responsive Neurostimulation System (RNS).

Main Results:

• Resective surgery generally offers superior seizure control compared to medication for DRE.
• Minimally invasive epilepsy surgeries (MIS) and neuromodulation demonstrate promising seizure outcomes.
• These advanced techniques aim to minimize complications and patient concerns associated with traditional epilepsy surgery.

Conclusions:

• Minimally invasive epilepsy surgeries and neuromodulation represent significant advancements for DRE management.
• These techniques offer viable alternatives for patients with drug-resistant epilepsy, potentially improving quality of life.
• Further research and systemic improvements are needed to increase access to and optimize the use of epilepsy surgical options.
