We reviewed 41 studies on epilepsy surgery in 1645 children and adolescents. The available data vary greatly from one paper to another, particularly as regards the age of the patients included, selection criteria, presurgical methodology, and the type of surgical intervention. Moreover, the surgical results are classified according to very different criteria. Our experience in Grenoble concerning 55 children (age < or = 16 years; postoperative follow-up > 18 months) is discussed in the light of data in the literature. The need is stressed for a consensus on the type of information that must be supplied by well-detailed studies on homogeneous groups of epilepsy surgery patients.
