We report evaluation and results in 100 patients who had undergone anterior temporal lobectomy for intractable complex partial seizures. Average follow-up was 9.0 years (range, 2 to 21 years). In the 2nd postoperative year, 63% were seizure free, 16% were significantly improved, and 21% were considered not significantly improved. Mean number of seizures in the last group was 27% of preoperative levels. Surgical results did not change significantly in subsequent postoperative years; good outcomes tended to persist over the longer term. We also examined the utility of continuous depth electrode monitoring in the evaluation of patients with independent bitemporal interictal epileptiform activity. Despite limited numbers of subjects in this category, there was a trend toward improved surgical outcome when such subjects were evaluated with depth electrodes.
