This original book provides a comprehensive overview of endoscopic ear surgery through more than 70 clinical cases, covering the external ear canal, tympanic membrane perforations, and ossicular chain surgery, including ossiculoplasties, and stapes procedures. This work is the result of a collaboration among prominent experts from all over the world. Many of these experts are members of the International Working Group on Endoscopic Ear Surgery (IWGEES). The contributors describe real cases from their own practice, and each clinical case combines commentaries, key points, color illustrations, drawings, decision trees, and the latest bibliographic references, with step-by-step surgical videos explaining anatomy, techniques, devices, tips, and pitfalls. Given its very practical approach, this volume will be an essential companion for surgeons wishing to improve their technique, as well as for beginners in the field of endoscopic ear surgery. This volume is part of a comprehensive and innovative approach to ear endoscopy. It is complemented by a second volume dedicated to additional key areas of ear surgery, including congenital and acquired cholesteatoma, tympanic retraction pockets, middle ear tumors, facial nerve, inner ear surgery, lateral skull base surgery, and cochlear implantation. Together, the two volumes constitute a complementary reference set, offering comprehensive coverage of ear surgery and serving as an invaluable resource for surgeons in the meticulous planning and preparation of their cases.
