In the Netherlands all patients who are considered candidates for surgical treatment of their epilepsy are referred to the Dutch Workgroup for Functional Neurosurgery. Resective neurosurgery in partial epilepsy is a focus of special interest of national health authorities. Annually 15-20 patients can now be operated upon. Presurgical evaluation includes a.o. 18/FDG PET. For depth-EEG recording a specially designed method of "Combined Subdural and Depth-EEG Recording" is used which has been described previously. 70 patients underwent depth-EEG recording with the combined method. In 4.2% of the patients there were transient complications, in 1.4% there was a possibly permanent slight neurological deficit caused by the method. Fifty-six patients were evaluated at least one year after their surgical treatment (median follow-up 3 years). In the frontal lobe group comprising 9 patients 56% were seizure-free, 76% benefited from the treatment. In the temporal lobe group with 47 patients 68% were seizure-free and 92% benefited. No patient deteriorated from the resection. Permanent morbidity was nil.
