Surgery for medically intractable temporal lobe epilepsy during early life

Area of Science:

• Pediatric Neurology
• Neurosurgery
• Epileptology

Background:

• Early-life temporal lobe epilepsy (TLE) can be devastating, causing drug-resistant seizures and neurological decline.
• Limited data exists on epilepsy surgery outcomes in infants and young children, especially for TLE.

Purpose of the Study:

• To evaluate the efficacy and safety of temporal resection for TLE in children under five years old.
• To assess seizure control and neurological outcomes following surgery in this specific pediatric population.

Main Methods:

• Retrospective analysis of 20 children under age 5 who underwent temporal resection for TLE.
• Minimum 2-year follow-up period to assess seizure outcomes and complications.
• Utilized EEG, MRI, and SPECT for diagnosis and localization.

Main Results:

• 65% of children achieved seizure freedom, and 15% had over 90% seizure reduction at a mean follow-up of 5.5 years.
• Diverse clinical presentations included psychomotor seizures, motor changes, and epileptic spasms.
• Common pathologies included cortical dysplasia (8/20) and tumors (8/20), with hippocampal sclerosis in 4 cases (often dual pathology).

Conclusions:

• Temporal lobe epilepsy in early life presents with varied and severe symptoms.
• Excisional surgery for TLE in young children yields favorable seizure reduction rates comparable to older patients.
