Relationship of cisterns to vessels and relationship of cranial nerves to intra- and extradural structures (Figs. 52 to 60, and Figs. 7, 10, 14, 17, 22 to 24, 29, 31, 38, 40, 43, and 49)

Abstract

The topography of the brain and its vessels and cranial nerves is defined using imaging methods. CTs and MRTs with 3D reconstruction may be applied into addition to cadaver brain dissections. Individual exact distance measurements can be taken from the imaging studies nowadays. Even high resolution imaging does not allow the definition of arachnoid structures, fine vessels or fascicles of cranial nerves. Here cadaver brain-and skull-dissections are necessary to acquise the microsurgical and endoscopic techniques, as demonstrated in Freiburg in 2006 by Al Mefty, and by Snyderman et al.
