New research supports earlier consideration of minimally invasive epilepsy surgery, yet an estimated 65% of candidates never receive a surgical evaluation.

Minimally invasive epilepsy surgery is well tolerated and, for many children with treatment-resistant epilepsy, can lead to seizure freedom faster than families may expect — changing the course of a child’s life sooner and helping them regain a more normal childhood.

“The perception of ‘epilepsy surgery’ is sometimes still associated with an earlier era of the field: a major operation, long recovery and a last resort,” said Ian S. Mutchnick, M.D., pediatric neurosurgeon with Norton Children’s Neuroscience Institute, affiliated with UofL School of Medicine. “That perception, more than clinical reality, can keep epilepsy patients out of the surgical pipeline.”

An estimated 65% of children who are appropriate epilepsy surgery candidates never receive a surgical evaluation.

“Minimally invasive epilepsy surgery techniques at Norton Children’s Neuroscience Institute offer children with drug-resistant epilepsy a well-tolerated path that, in many cases, delivers seizure freedom more safely and with less disruption to childhood than families might assume,” Dr. Mutchnick said.

A safer path to seizure control

Across two recent studies, minimally invasive and neuromodulatory epilepsy surgery techniques show consistently favorable safety profiles, shorter recoveries and seizure-freedom rates, even in complex cases.

Dr. Mutchnick co-authored a 22-year national analysis, published in Epilepsia, examining pediatric drug-resistant epilepsy (DRE) surgery through the National Inpatient Sample from 1998 to 2020. The study compared open resection against minimally invasive and neuromodulatory options such as laser interstitial thermal therapy (LITT), vagus nerve stimulation (VNS) and responsive neurostimulation (RNS).

Complication rates for LITT, VNS and RNS stayed under 10%, versus 16% for open surgery. For hospital stays, the median was just one day for LITT and VNS, and two days for RNS, versus seven days for open resection. Discharge-to-home rates ranged from 94% to 100% across the minimally invasive categories, and mortality was at or near 0% for every technique studied. Adoption of LITT and RNS has climbed steadily since their introduction, a trend the authors link to growing confidence in these approaches.

“For a child with drug-resistant seizures, that shorter recovery window means less time in a hospital bed and more time back in a classroom, participating in activities and socializing with peers,” Dr. Mutchnick said.
Achieving seizure freedom, even in complex cases

A second study, published in the Journal of Neurosurgery: Pediatrics, reinforces the point in a harder population to treat: extratemporal lobe epilepsy (ETLE), historically tied to lower seizure-freedom rates than temporal lobe epilepsy. Among 29 pediatric ETLE patients treated with LITT, 41.4% were completely seizure-free at 12 months and 48.3% achieved a good overall outcome (International League Against Epilepsy Class 1-3), results comparable to open resection in a population that has traditionally been harder to cure.

As for recovery metrics: mean length of hospital stay was 1.3 days, and no patient experienced a permanent neurological deficit, hematoma, infection or death. Only three patients had transient, steroid-responsive swelling that resolved within three months.

Patients whose PET imaging aligned with the eventual LITT ablation site had 8.8 times greater odds of a good outcome, illustrating evidence that careful, multimodal preoperative workups can meaningfully raise the odds of reaching seizure freedom on the first attempt.

Dr. Mutchnick has tracked the field’s evolution from a landscape dominated by craniotomy/open resection to one where LITT, RNS and VNS now offer children a faster, better-tolerated route to seizure control. These procedures are part of the broad spectrum of epilepsy treatment options available at Norton Children’s Neuroscience Institute.

For referring providers

According to Dr. Mutchnick, further efforts are required to close the surgical treatment gap — with early referrals serving as a meaningful way to improve epilepsy patient outcomes.

“Early referral doesn’t commit a family to surgery, but it can open the door to options that allow children to achieve seizure freedom sooner,” he said.
