The ear is a sensory system consisting of organs which help in hearing sounds. The main ear diseases include otosclerosis, Ménière's disease, tinnitus, barotrauma and presbycusis. Tinnitus is an ear disease which results in perception of sound in absence of any external sound. Otosclerosis is a disease caused due to the development of small bones in the ear. Ménière's disease is a condition affecting the inner parts of the ear resulting in hearing loss and pressure in the ear. The diagnosis of ear diseases generally involves a physical exam, assessment of medical and health history, and undertaking a hearing test. The requirement for imaging studies arises in case of suspicion of complications and when treatment does not work effectively. Computed tomography and magnetic resonance imaging are utilized to diagnose inner ear pathology. The drugs that are utilized to tackle the inner ear diseases include neurotrophins, corticosteroids, antioxidants, anesthetics and aminoglycoside antibiotics. This book provides comprehensive insights on ear diseases. It includes some of the vital pieces of work being conducted across the world, on various topics related to diagnostic imaging and therapeutics for diseases related to the ear. Medical professionals and students actively engaged in the study and management of these diseases will find this book full of crucial and unexplored concepts.
