Summary

The authors present the surgical results of the first 20 out of 24 medically uncontrollable epileptic patients operated on using the technique described by Talairach et al. The minimum postoperative follow-up period was 6 months and the mean 19.6 months. 12 patients became seizure free. Three patients have had a significant decrease in the number of seizures and 5 have had the frequency of attacks reduced to 20-50% of the preoperative level. In 11 of the 20 patients, the epileptogenic zone lay in the frontal lobe.

Of the 12 patients in whom the delimitation of the epileptogenic zone was correct, only one has seizures, and these occur only 20% as frequently as during the preoperative period. Five patients with frontal epilepsy showed obviously bilateral foci in the SEEG study. In these cases it was decided to resect the more severely affected side and Overall results have been poor.

It is apparent that the correct location and delimitation of the epileptogenic zone and achievement of optimal surgical results is more difficult in frontal lobe epilepsy and in epilepsy of the temporo-parieto-occipital area.
