Objective: To describe localizing value of surface EEG recording in the presurgical evaluation of medically intractable pediatric epilepsy patients.
Methods: We review the relevant concepts required for understanding the role of surface EEG in the presurgical evaluation and in identifying the epileptogenic zone. The unique features of EEG and its limitations are discussed.
Conclusion: Despite recent technological advancements, surface EEG continues to play a crucial role in defining the epileptogenic zone, and thus in presurgical planning.
