Opercular reflex seizures: A case report with stereo-electroencephalographic demonstration

Reflex epileptic seizures of opercular origin have been described previousl y based on video-electroencephalographic monitoring, but very few patients have been explored with depth electrodes. We report a woman with late-onset epilepsy who had intractable seizures despite trials of several antiepilep tic drugs. At the time of the depth-electrode recordings, seizures were usu ally continuous and occurred either spontaneously or were induced by moveme nts of the jaw and mouth. The seizures originated in the deep central operc ular cortex; localization was confirmed by a good surgical outcome.
