The aim of this book is to enable the reader to reach a fast and accurate diagnosis of ear disease in the dog and cat and then to manage the treatment. Ear disease, particularly otitis externa is a common condition presented in veterinary practice and is not always obvious to the pet owner. Other vital conditions covered include otitis media, vestibula syndrome or acquired conducive deafness which, although less commonly seen in practice, can be devastating to the animal concerned.
All three authors are actively involved in the diagnosis and management of ear disease, both in first opinion and referral practice. Between them, they encompass the three major disciplines necessary – dermatology, neurology and surgery. Illustrated throughout with superb colour photographs and fully referenced, this book will be of value to veterinarians in both training and practice.
