This book aims to provide the trainee surgeon with the anatomical knowledge required to perform safe endoscopic sinus surgery. It provides a stepwise approach to sinus anatomy and is loosely based around the curriculum of the University of Cambridge Endoscopic Sinus Anatomy Course. High quality images derived from cadaver dissection, with CT scan radiological correlates and endoscopic photographs, are used throughout. This book is ideal for trainees at registrar or resident level for use in the operating theatre and as a dissection guide for cadaver endoscopic sinus surgery courses. The authors, with plenty of experience in running such courses, add useful clinical and surgical information as relevant.
