title: Determination of precise focus distribution and tailored lobectomy in temporal lobe epilepsy.
abstract: For the purpose of precise localization of epileptic foci, combined depth and subdural electrodes were applied to patients with intractable complex partial seizures. To determine speech-related areas, extraoperative functional mapping of the temporal lateral cortex was also carried out through the subdural electrodes. Based on these data, the extent of surgical resections was tailored to include as much of the epileptogenic areas as possible, while preserving the functionally essential zones of the lateral cortex. The results thus acquired have been satisfactory in terms of seizure control and the preservation of speech function.
