Cortical Resections in Drug Resistant Epilepsy
Cortical Resections in Drug Resistant Epilepsy
The aim of the study is to evaluate safety and efficacy of epilepsy surgery in the form of
 cortical resections in patients with refractory epilepsy and to review outcomes of resection
 procedures in focal epilepsy.
Nearly one-third of epilepsy patients are refractory/resistant to medical treatment .
 Refractory or drug-resistant epilepsy is defined as resistance to treatment with two
 appropriately chosen and tolerated antiepileptic drugs (AED) . Nevertheless, epilepsy surgery
 is an effective alternative treatment for some patients as it suggests seizure freedom .
 During the past 3 decades, surgery has found more acceptance as an option for drug-resistant
 epilepsy . Developments made in surgical techniques (cortical resections) have significantly
 increased the effectiveness and safety of these techniques; as such techniques have been
 demonstrated to improve seizure control/freedom outcomes and enhanced quality of life in
 patients . Neuro imaging developments with the introduction of positron emission tomography
 (PET), magnetic resonance imaging (MRI), functional MRI, single-photon emission computed
 tomography (SPECT), and magneto encephalography, electroencephalography and neuronavigation
 have facilitated the presurgical evaluation of patients, thus providing the lesion-directed
 surgeries more possible , also reducing the number and severity of complications .
 Complications of epilepsy surgery including failure to stop seizures and neuropsychological,
 psychosocial, or psychiatric impairment are still difficult to define, and there is no
 universal consensus in this regard .

 This technique characterized by :

 • Once the epilepsy focus is located by using interpretation and collection of data from
 functional MRI, EEG long term video and clinical findings, the specific surgery involved in
 treatment is decided on. The type of surgery depends on the location of the seizure focal
 point. Surgeries for epilepsy treatment include, but are not limited to, the following types:
 temporal lobe resection, ground temporal and extra temporal resection, parietal resection,
 occipital resection, frontal resection, extra temporal resection.
