This color atlas, compiled by five experienced clinicians from Europe and the USA, is the first German-language professional book to describe the most common clinically relevant diseases of the ear, upper respiratory tract, oral cavity, and pharynx in small animals. The head and neck region is divided into six anatomical areas, each addressed in a dedicated chapter of the book. Following a brief introduction to the anatomy and physiology of the respective area, various case studies are discussed in detail regarding etiology, diagnostics, differential diagnosis, therapy, and disease progression. The concept of this practical professional book is to allow the veterinarian to first make a diagnosis and develop a treatment plan after reading the respective medical history. The reader can then verify their approach.
