The first edition of William Lincoln Ballenger’s Diseases of the Nose, Throat and Ear: Medical and Surgical was published in 1908 and has since sold over 150,000 copies worldwide in 11 languages. The 18th edition has expanded to 114 chapters, continuing the tradition of excellence and applying Ballenger’s original concept of combining an atlas with text to produce a comprehensive reference for practitioners of the 21st century. Color plates, illustrations, endoscopic photographs, and other color photographs illuminate surgical concepts, the foundations of underlying disease, and procedures. Section editors and senior authors were selected for their valuable contributions
