This publication is dedicated to healthcare professionals, residents, and medical students seeking a practical and up-to-date resource in this subspecialty.Over the past three decades, I have been fortunate to care for countless patients with thyroid disorders, and I have learned invaluable lessons from my colleagues, mentors, and the institutions where I have worked. My goal is to distill this knowledge into a clear and concise text that will serve as a valuable reference for all those interested in thyroid surgery.This guide will cover the most relevant aspects of thyroid pathology, with a particular focus on thyroid cancer. I will present the latest advances in diagnosis and surgical treatment, as well as strategies for preventing and managing complications. To enhance understanding, I have included numerous illustrations and diagrams.I hope that this manual will contribute to the ongoing training of future surgeons and ultimately improve the care of patients. While this work represents my personal perspective based on my experience an thorough review of the literature, I acknowledge the contributions of countless researchers and clinicians who have shaped the field.
