Summary
Extraoperative electrocorticography (ECoG) using epidural electrodes enables precise seizure localization in children. This technique improves surgical outcomes for intractable focal seizures, with 65% of resected patients experiencing seizure freedom or significant reduction.
Area of Science:
- Neurosurgery
- Pediatric Neurology
- Epilepsy Surgery
Background:
- Extraoperative electrocorticography (ECoG) using epidural electrodes allows functional localization in awake children.
- This technique enables cortical excisions based on criteria similar to adult procedures under local anesthesia.
- Simultaneous ECoG and video monitoring during seizures offers crucial localizing data impractical under local anesthesia.
Observation:
- Experience with 75 children (5 months to 15 years) managed with epidural electrode arrays is reported.
- Illustrative cases demonstrate the feasibility and utility of extraoperative ECoG in pediatric patients.
- Gliomas are identified as a common cause of chronic focal seizures in children.
Findings:
- Of 49 children undergoing resection, 32 (65%) achieved seizure freedom or significant seizure reduction.
- Surgical outcomes correlate with specific pathologic entities causing intractable focal seizures.
- The study distinguishes pathologies responsive to surgical intervention from those that are not.
Implications:
- Extraoperative ECoG is a valuable tool for pediatric epilepsy surgery.
- Accurate localization improves quality of life for children with intractable focal seizures.
- Understanding the underlying pathology is crucial for predicting surgical success in pediatric epilepsy.
