Diseases of the ear, nose, throat, larynx, neck, and skull base require not only solid knowledge of anatomy, physiology, and pathology but also heightened clinical judgment, skill, and collaboration with other specialties.

This complexity makes the presence of modern manuals essential, covering the specialty comprehensively with scientific validity and pedagogical excellence.

This work is structured to serve multiple needs: understanding the basic principles for students, systematic preparation for specialists, and the immediate reference needed by practicing physicians in daily clinical practice.

Each chapter is authored by specialized scientists with deep knowledge and experience in the subject. Special emphasis has been placed on presenting clinical examples, diagnostic algorithms, and treatment options, based on evidence-based medicine and international guidelines.
