Endoscopic ear surgery,(EES) is defined as the use of the rigid endoscope, in contrast to the operatingroom microscope, to visualize the middle and inner ear during otologic surgery. During endoscopic earsurgery the surgeon holds the endoscope in one hand while working in the ear with the other.Endoscopic visualization has improved due to high-definition video imaging and wide-fieldendoscopy, and being less invasive. EES is gaining importance as an adjunct to microscopic ear surgery.The contents of this book cover every aspect of endoscopic ear surgery. This book is a comprehensiveoverview and provides a significant information on this field. The techniques have been supported withadequate number of tables, diagrams and photographs and clearly explains the basics of this fieldincluding scientific principles. Scientists and students actively engaged in this field will find this bookfull of crucial and unexplored concepts. It is hoped that this book is sufficiently comprehensive to guidethe surgeons of this branch. Main aim of this book is to provide a mature approach to basic principles ofthis branch of surgery.
