Pediatric epilepsy surgery is increasingly viable due to advanced diagnostics and safer neurosurgery. Early surgical intervention for drug-resistant epilepsy in children offers significant benefits for seizure control and quality of life.

Area of Science:

  • Pediatric Neurosurgery
  • Epileptology
  • Neuroimaging

Background:

  • Childhood epilepsy surgery is advancing with improved presurgical techniques and neurosurgical safety.
  • Resective and functional surgeries are options, with temporal lobectomy and hemispherectomy being most common.

Purpose of the Study:

  • To review current presurgical evaluation methods for pediatric epilepsy surgery.
  • To highlight the importance of tailored approaches considering the wide range of pediatric presentations.

Main Methods:

  • Noninvasive evaluations including optimized MRI (3D datasets) and video electroencephalography (EEG) telemetry.
  • Advanced neuroimaging like quantitative/semiquantitative MRI, ictal/interictal SPECT, and interictal PET.
  • Neuropsychological testing and functional MRI (fMRI) for assessing cognitive function and cerebral dominance.

Main Results:

  • Optimized MRI and video EEG telemetry are crucial for documenting seizures and identifying abnormalities.
  • SPECT and PET offer complementary information, especially in infants with incomplete myelination.
  • Neuropsychology and fMRI aid in determining cerebral dominance and functional localization.

Conclusions:

  • Presurgical evaluation for pediatric epilepsy surgery requires a comprehensive, individualized approach.
  • Careful consideration of surgical timing and drug resistance definition is vital in young children.
  • Successful epilepsy surgery in children can lead to seizure elimination or reduction, improving long-term outcomes.
