- Abstract
Several preoperative clinical variables have been reported to have value as predictors of seizure outcome following the surgical resection of epileptogenic focus in adults who have had medically refractory epilepsy. The present paper reports the results of a retrospective review of the ability of these variables to predict seizure outcome in a group of pediatric patients who had medically refractory epilepsy and underwent surgical resection of an epileptogenic focus at the Children's Hospital of Eastern Ontario. Variables in this review included age at first seizure, age at time of surgery, duration of seizures, seizure type, sex, family history, etiology, level of intelligence, EEG data, results of imaging studies, findings on examination of the central nervous system, and location and site of surgical resection. We found 64 patients who met the entry criteria for this review. Normal intelligence and tumor as etiology were associated with a good postoperative seizure outcome in patients who had a temporal resection; no variables had positive correlation with outcome in the extratemporal group. Caution must be used in the extrapolation of data and inclusion of studies of predictors of seizure outcome for adults to pediatric age groups.
