This book presents the latest and most cutting-edge surgical techniques with results achieved, as well as information that will enable the surgeon to create a three-dimensional mental image of the anatomy from the CT scans, so as to reduce the risk of every procedure. This theme will be carried through all the chapters. Endoscopic Sinus Surgery will thoroughly familiarize surgeons with intraoperative anatomic landmarks. It includes a separate section on Image-Guided Surgery, discussing when to use, how to use, and the value of this technique. This book is unique in that it will focus only on anatomy and surgical techniques with the accompanying video footage of the operations on the CD-ROM, which will also be designed to present examples of the anatomic variations that occur between individual patients. This accompanying CD-ROM will include Powerpoint presentations, and videos with audio commentary. The unusual organization of presenting anatomical information sequentially for all the aspects of the sinuses allows for a more focused and useful approach.
