This book addresses the increasing need for a text related to endoscopic-based middle ear surgery, offering the reader a step-by-step surgical dissector that focuses on high quality images, illustrations, and videos. Written by well-respected physicians at Harvard University and the Massachusetts Eye and Ear Infirmary, who have spent years researching endoscopic middle ear surgery, this book discusses the important benefits of an endoscope compared to a microscope. Additionally, the use of high quality medical illustrations and high-resolution images of endoscopic middle ear surgery, otologists, otolaryngologists, and neurologists alike will acquire basic endoscopic ear surgery techniques. ?? ?Endoscope-based otologic surgery is a fast growing field and the use of rigid endoscopes to perform ear surgery, rather than just to visualize the middle ear, is increasing and primed to expand as refined instrumentation and operative approaches become available.
