The introduction of the endoscope for neurosurgical procedures began with great promise. It was developed to provide a magnified anatomical view of the ventricular system in a minimally invasive manner. The early endoscopes were too primitive for the majority of procedures performed today. The advent of illumination, optical systems, and modern endoscopes allow the neurosurgeon to perform these previously inoperable cases. This book introduces all aspects of the modern endoscope system, physics of optics, and all the techniques of intracranial neuroendoscopy. This is a must-have book for all levels of surgeons, residents, operating room staff, and anyone who wants to learn about endoscopy and its potential applications.
