Trends in pediatric epilepsy surgery

Area of Science:

• Pediatric Neurology
• Neurosurgery
• Epileptology

Background:

• Epilepsy surgery is an established treatment for drug-resistant epilepsy in children.
• Its application has significantly increased in India over the past decade.
• Early surgical intervention is crucial for children whose cognitive and behavioral development is compromised.

Purpose of the Study:

• To review key aspects of pediatric epilepsy surgery for general pediatricians.
• To highlight the importance of timely surgical evaluation and intervention.
• To discuss advancements in pre-surgical evaluation and surgical techniques.

Main Methods:

• Comprehensive pre-surgical evaluation including clinical assessment, EEG (inter-ictal, ictal, video-EEG), and advanced neuroimaging (MRI).
• Analysis of seizure semiology and electroencephalography (EEG) data.
• Consideration of invasive EEG for discordant or non-lesional cases.
• Palliative surgical options like corpus callosotomy and vagal nerve stimulation for generalized or multi-focal epilepsy.

Main Results:

• Resective surgery offers good outcomes in approximately two-thirds of pediatric patients.
• The procedure is associated with low rates of morbidity and mortality.
• Advances in MRI have improved the identification of surgical candidates.

Conclusions:

• Epilepsy surgery is a safe and effective treatment option for drug-resistant pediatric epilepsy.
• A multidisciplinary pre-surgical evaluation is essential for optimal patient selection.
• Preservation of eloquent cortical areas is a critical consideration during surgery.
