Summary
This summary is machine-generated.

Augmented reality (AR) enhances pediatric epilepsy surgery by improving navigation and enabling precise resection of seizure zones. This approach demonstrated low morbidity and favorable seizure outcomes in a retrospective study.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Augmented Reality

Background:

  • Augmented reality (AR) is increasingly utilized in surgical procedures for enhanced planning and real-time guidance.
  • Pediatric epilepsy surgery presents unique challenges in precisely identifying and resecting epileptogenic zones.

Purpose of the Study:

  • To investigate the feasibility and outcomes of using AR-enhanced neuronavigation in pediatric epilepsy surgery.
  • To evaluate the safety and efficacy of AR-assisted surgical resections in a pediatric population.

Main Methods:

  • A retrospective study involving 43 pediatric patients undergoing epilepsy surgery between October 2020 and October 2023.
  • Functional neuronavigation integrated multimodal imaging data (fMRI, DTI, PET, SPECT, sEEG) with AR to overlay surgical fields.

  • AR maps were transferred to the surgical microscope for real-time guidance during resection.

    • Main Results:

    • No adverse events were reported with AR-enhanced neuronavigation.
    • Among 24 patients with over one year follow-up, 83.3% achieved favorable ILAE grade 1 seizure outcome.
    • Histological diagnoses included Focal Cortical Dysplasia (FCD), ganglioglioma, and Dysembryoplastic Neuroepithelial Tumors (DNET).

    Conclusions:

    • AR-supported navigated microscope resection is a feasible and safe technique for pediatric epilepsy surgery.
    • This method allows for accurate targeting and removal of both lesional and non-lesional epileptogenic zones.
    • The approach is associated with low morbidity and promising seizure control rates.
