Covering all aspects of the anatomy, physiology, diagnosis, and treatment of hearing loss, this is an accessible and comprehensive text for all clinicians interested in expanding their knowledge of hearing loss. There have been many exciting developments in the nearly two decades since the fourth edition was published. This revised edition includes new material on cochlear biology, synaptopathy, regenerative therapy for sensorineural hearing loss, systemic causes of hearing loss such as autoimmune inner ear disease, advances in audiometry and aural rehabilitation, and many other topics. In addition, it contains expanded chapters on tinnitus, dizziness, and facial paralysis, as well as updated material on otoacoustic emissions, sudden hearing loss, hearing protection devices, temporal bone tumors, nutraceutical research and hearing in dogs. The book is extensively augmented with case reports that illustrate important principles. The book is of value to otolaryngologists, general practitioners, pediatricians, residents, medical students, audiologists, nurses, audiometric technicians, attorneys, and other professionals with an interest in the ear and hearing.
