“…Noninvasive and invasive mapping and definition of seizure focus Details of the preoperative evaluation protocol have been published elsewhere (Liiders, et al, 1983Lesser et al, 1984;Morris et al, 1986;Wyllie et al, 1987). Prolonged video and noninvasive EEG monitoring was done on at least two separate occasions, with tapering of antiepileptic drugs (AEDs) as needed to record several of the patient's typical seizures (Ives and Gloor, 1978;Mattson, 1980;Luders et al, 1987). Standard scalp electrodes were placed according to the International 10-20 system, and additional scalp electrodes were applied between and below the 10-20 positions over areas.of interest.…”

Forty-seven patients with structural brain lesions on neuroimaging studies and partial epilepsy intractable to medical therapy were studied. Prolonged noninvasive interictal and ictal EEG recording was performed, followed by more focused mapping using chronically implanted subdural electrode plates. Surgical procedures included lesion biopsy, maximal lesion excision, and/or resection of zones of epileptogenesis depending on accessibility and involvement of speech or other functional areas. The epileptogenic zone involved exclusively the region adjacent to the structural lesion in 11 patients. It extended beyond the lesion in 18 patients. Eighteen other patients had remote noncontiguous zones of epileptogenesis. Postoperative control of epilepsy was accomplished in 17 of 18 patients (94%) with complete lesion excision regardless of extent of seizure focus excision. Postoperative control of epilepsy was accomplished in 5 of 6 patients (83%) with incomplete lesion excision but complete seizure focus excision and in 12 of 23 patients (52%) with incomplete lesion excision and incomplete focus excision. The extent of lesion resection was strongly associated with surgical outcome either in itself (p less than 0.003), or in combination with focus excision. Focus resection was marginally associated with surgical outcome as a dichotomous variable (p = 0.048) and showed a trend toward significance (p = 0.07) only as a three-level outcome variable. We conclude that structural lesions are associated with zones of epileptogenesis in neighboring and remote areas of the brain. Maximum resection of the lesion offers the best chance at controlling intractable epilepsy; however, seizure control is achieved in many patients by carefully planned subtotal resection of lesions or foci.(ABSTRACT TRUNCATED AT 250 WORDS)

“…In the remaining 15% of the recorded attacks, the brain waves are obscured by muscle artifact, and the lateralization of the attack cannot be determined despite replaying the tape and using sophisticated filter technology. When visualization of the attack pattern and correlation with the EEG record is needed, continuous video monitoring (Ives and Gloor, 1978b) is added to the system (Fig. 2), filming at a rate of three frames per second so a single reel of video tape permits 18 h of continuous taping before the tape cassette needs to be replaced.…”

The underlying seizure tendency of complex partial seizures often involves the temporal region of the brain, but the frontal lobe can also produce similar complex partial seizures. By the end of 1980, 1,210 patients with medically refractory temporal lobe epilepsy had been operated on at the Montreal Neurological Institute. Nontumoral epileptogenic lesions were present in 1,034 patients, 169 had tumors, and 7 had major vascular malformations. Thirty-seven percent of the 894 evaluable patients with nontumoral epileptogenic lesions have become and remained seizure-free. Two hundred thirty-six (26%) patients had a marked reduction of seizure tendency. Within the seizure-free group, 63% had a complete or nearly complete reduction of their medically refractory tendency following temporal lobectomy. Of the patients with temporal lobe epilepsy due to tumoral lesions, 46% of the evaluable patients have become and remained seizure-free, and 76% have had a complete or nearly complete reduction of seizure tendency.

“…During the 1970s, this advance was accompanied by simultaneous cinemagraphic, and then video monitoring, of ictal behavior, in order to obtain second-by-second electroclinical correlations of ictal onset and propagation. Over the next decade, EEG artifact rejection became sufficiently sophisticated to permit long-term video and EEG monitoring using scalp and sphenoidal electrodes (60,61). …”

The objective of this article is to review the dramatic changes that have occurred in the field of epilepsy surgery since the founding of Epilepsy Action in 1950. We have chosen to consider these advances from the biomedical perspective (the physician and basic scientist), and the behavioral perspective (the psychologist and the patient). Both of these viewpoints are equally important in understanding the evolution of epilepsy surgery over the past 60 years, but may not always be well synchronized.
