Abstract
Cisterna ambiens, Cisterna valleculae and Cisterna fossae lateralis form an U-shaped configuration surrounding the base of Uncus. The roof of Cisterna ambiens is the flattened Tractus opticus, which is not useful as a surgical landmark during amygdalectomy, in contrast to the medial extension of this cistern, Cisterna cruralis. In this area Tractus opt. is readily identifiable. Resections of Corpus amygdaloides (which is enclosed by Gyrus uncinatus) might jeopardize Aa. perforantes crossing Uncus-Amyg-dala- base. Furthermore the pyramidal tract, which is located close to this area, surrounded by the flattened Tractus opt. is put at risk.
