An Introduction to Minimally Invasive Pediatric Epilepsy Surgery

Abstract

The field of minimally invasive surgery has evolved over the past 50 years, including neurosurgery, with an evolution to “minimally invasive neurosurgery” when feasible. Epilepsy surgery has followed this trend, with a transition from standard neurosurgical techniques to minimally invasive techniques in all phases of neurosurgical involvement. These include the diagnostic intracranial electroencephalogram with a subdural exploration to stereoelectroencephalography, the actual resection from an open craniotomy to a less destructive technique, or the multiple modalities of neuromodulation instead of a destructive surgery.The influence of these minimally invasive techniques has resulted in a change in the overall philosophy of pediatric epilepsy surgery. The expectations of what is considered “successful” epilepsy surgery has changed from total seizure control, in other words, a “cure,” to palliative epilepsy surgery with a decrease in the targeted seizures, especially “disabling seizures.” This has led to an overall greater acceptance of epilepsy surgery. This article summarizes the major reasons behind the explosion of minimally invasive pediatric epilepsy surgery, which are amplified in the subsequent articles. Some of this chapter includes the authors' opinions.
