Transcanal endoscopic ear surgery (TEES) is minimally invasive surgery to operate on tiny, delicate structures within the middle ear. It differs from traditional ear surgery in that surgeons access the middle ear through the ear canal rather than through an incision behind the ear. This atlas is a step by step guide to TEES for practising and trainee otologists. Divided into 15 sections, the book begins with an overview of the history and principles of endoscopic ear surgery. The next chapters cover middle ear anatomy, operation theatre set up, instruments, and imaging. The remaining sections describe TEES techniques for different disorders, covering both basic and advanced procedures, concluding with a chapter on recent advances and future developments. Presented in a step by step approach, each method is explained clearly with pre- and intraoperative considerations and guidance on their management. The book is highly illustrated with more than 400 high definition figures and 140 hand-drawn images demonstrating each step of surgery. Tips and pearls are also included. With this comprehensive atlas, comes access to operative videos via a QR code provided in the book.
