Summary

Ear, Nose, Throat, and Tracheobronchial Diseases in Dogs and Cats is the first textbook to provide a complete overview of all ENT diseases, both common and rare. It includes such problems as inflammation of the outer ear, deafness, nasal discharge, swallowing disorders, and cough. Detailed and up-to-date clinical information gives insight into ENT function and dysfunction for teachers and researchers, veterinarians in practice and veterinary students.Six chapters give key information on functional considerations, etiology, clinical signs, diagnosis, and therapy of ENT disorders. Special diagnostic and imaging techniques are described in detail. Approximately 180 top quality illustrations emphasize and supplement the specific features of the diseases and disorders described in the text. A detailed index gives easy access to the content of this book.This unique textbook will provide a highly useful and informative reference guide to everyday practice, based on the author's 35 years as a specialist in ear, nose, throat, and tracheobronchial diseases in companion animals.
