[Identification of temporal epilepsy in children: contribution of sphenoidal electrodes]

The authors have evaluated the indications, method and results of utilising sphenoidal electrodes in epilepsy. This method makes it possible to study the hippocampal area which cannot be studied by extra-cranial electrodes. It also localizes in the temporal lobe complex seizures without investigation by an electroencephalogram, or with a non-specific electroencephalographic picture. Thus, sphenoidal electrodes enable temporal seizures to be identified and localized, leading to more specific neuroradiological exploration, and therefore to the selection of patients for specific surgery.
