Abstract

Keyhole Corticoamygdalohippocampectomy for Mesial Temporal Lobe Epilepsy

Author(s): Peng-Fan Yang

Keyhole corticoamygdalohippocampectomy is a modification of conventional trans- middle temporal gyrus selective amygdalohippocampectomy. It involves a small linear incision, a low anterior temporal keyhole craniotomy, a cylinder-like corridor through the anterior-most middle and inferior temporal gyri, and subpial resection of the hippocampus and amygdala. During this approach, the guidance of neuronavigation is not necessary and unaffected areas including the superior temporal gyrus and temporal veins are not exposed and manipulated. Compared with the conventional approach, this technique is easier, safer, and less traumatic to functional lateral neocortex.
