The “Encyclopedia of Neuroendoscopic Procedures” aims to be an expanding comprehensive educational tool that will cover all technical aspects of neuroendoscopy. It is aimed to demonstrate examples of all the possible technical variations that can be employed in any given procedure. The focus is on technique and not on disease pathology or indications for using a particular technique. For every type of operation, there are several presentations of clinical cases, each one of which demonstrates a particular variation of the technique.
