摘 要：Background: Drug-resistant epilepsy can be defined as the existence of seizures within 6 months, despite adequate therapy regimens with one or more antiepileptic drugs. Epilepsy surgery has been the standard therapy to help those patients who suffer from drug-resistant epilepsy. The goal of this surgery is to halt or reduce the intensity of seizures. This literature review aims to provide an overview of existing surgical procedures for the treatment of drug-resistant epilepsy and the degree of seizure control they provide based on available literature. Methods: Data were collected from medical journal databases, aggregators, and individual publications. The most used databases were PubMed, Medline and NCBI. Some of the keywords used to search these databases include: “drug resistant epilepsy, “seizure control, and “neurosurgery. Results: Epileptic surgery is divided into resective and non-resective procedures. Studies have shown that a full resection of the epileptogenic brain area increases the probability of seizure eradication, however, the risks of postoperative impairments grow as the resection area is extended. On the other hand, patients who are unsuitable for seizure focus removal by resective surgery, such as those with multifocal seizures or overlapping epileptogenic zone with a functional cortex, may benefit from non-resective surgical options such as Vagus Nerve Stimulation and Responsive Neurostimulation. Conclusion: This literature review discusses the comprehensive treatment of epilepsy, especially the surgical treatment of drug-resistant epilepsy. The reviewed studies have shown that epilepsy surgery has promising outcomes in achieving seizure freedom/reducing seizure frequency with minimal adverse effects when performed correctly with the appropriate choice of surgical candidates.
