Aims: To investigate post-operative seizure outcomes, and predictors of surgical outcomes of the malformation of cortical development (MCD) in children with drug-resistant epilepsy (DRE) and age-specific characteristics.
Methods: We retrospectively analyzed clinical data from 428 children with MCD-related DRE who underwent curative surgical treatment. Statistical analyses were conducted to identify correlative characteristics, prognostic predictors, and differences among various age groups.
Results: After more than 3 years of follow-up, 81.3% of patients achieved Engel I outcomes. Prognosis was correlated with factors such as age at surgery, MRI findings, invasive EEG, pathology, acute postoperative seizures (APOS), and the number of preoperative and postoperative anti-seizure medications (AEDs). Age at surgery and the number of preoperative AEDs (p < 0.001) were significant predictors of seizure recurrence. Distinct clinical characteristics were observed among different age groups.
Conclusion: Surgery is effective in terminating MCD-related DRE. Younger age at surgery and fewer preoperative AEDs are associated with better prognoses. Clinical characteristics vary significantly with age.
