Abstract

Temporal lobe epilepsy is one of the most frequent forms of drug-resistant epilepsy in adults. It has been well established that temporal lobectomy and amygdalohippocampectomy are more efficacious than medications for seizure control in patients with medial temporal lobe epilepsy. In epilepsy surgery, hippocampectomy means removal of the "hippocampal formation", i.e. the hippocampus and parahippocampal gyrus, because both structures are highly interconnected and associated with epileptogenesis. During the removal of the hippocampus, the hippocampal arteries are cut within the hippocampal sulcus, which is located between the fimbria and subiculum (parahippocampal gyrus). The anterior choroidal artery should also be identified in relation to the choroidal fissure, which becomes an important landmark in determining the superior limit of amygdala removal. En-bloc removal of the hippocampus and parahippocampal gyrus is accomplished safely by careful subpial dissection. In this article, we outline the surgical anatomy of the hippocampal formation required for transsylvian selective amygdalohippocampectomy.
