Endoscopic and microsurgical anatomy of the upper basal cisterns
Microsurgical techniques related to the basal cisterns and their walls were initially - veloped by Yasar ¸ gil based on anatomical and neuroradiological findings. Subsequently, numerous additional authors have contributed to the body of publications concerning the routine application of endoscopic techniques for intraventricular and intracerebral surgery guided by stereotaxy and/or neuronavigation. In the last ten years, transnasal endoscopic approaches for intrasellar target areas have been applied with increasing success. Snyderman and coworkers, as well as Al-Mefty and others have elaborated on these methods to approach areas within other basal cisterns. Today these applications, in particular regarding the problem of CSF-fistulas, are a source of controversy amongst neurosurgeons reminiscent of the scepticism towards microneurosurgery forty years ago. At that time, surgical techniques were developed to approach target areas within the brain, which could not be reached before. Similar aspects today are recognizable with reference to endoscopy. The author has confined his activities to the description of anatomical aspects of modern endoscopic neurosurgical techniques. The desire to impart this information to others has been the motivation for writing and illustrating this book. Three aspects regarding the present work should be noted: – The subject of this book is restricted to the presentation of the upper basal cisterns, except to some aspects regarding the fifth and sixth cranial nerves. The descriptions of anatomy and surgery inside the infratentorial cisterns are sufficient.
