Audiological medicine is a relatively new specialty spanning the investigation, diagnosis and medical management of hearing and balance disorders. Recent years have seen its growth as a separate medical discipline, although its practice depends not only upon a clear understanding of the basic sciences relevant to auditory and vestibular function, but also upon experience and knowledge in a wide range of clinical disciplines relevant to hearing and balance disorders, including genetics, immunology, pediatrics, geriatrics, neurology, otolaryngology, ophthalmology, psychiatry and general internal medicine. A Textbook of Audiological Medicine integrates the science and medicine of auditory and vestibular disorders, providing the first comprehensive textbook on the subject. There are five main sections; the first deals with both the auditory and vestibular systems, and then each system is considered in terms of the relevant basic sciences and clinical disorders.
