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.

This is a comprehensive survey of imaging of the petrous temporal bone; it includes the imaging appearances of both rare and common pathology. All the latest imaging techniques are included, in particular magnetic resonance with the new paramagnetic contrast agent Gadolinium DTPA. Opening chapters give an account of imaging techniques and normal anatomy and are followed by chapters on congenital ear disease, trauma, inflammatory disease and neoplasia; acoustic neuroma is given a separate section. The two concluding chapters are on vertigo and otosclerosis.

This open access book offers an essential overview of brain, head and neck, and spine imaging. Over the last few years, there have been considerable advances in this area, driven by both clinical and technological developments. Written by leading international experts and teachers, the chapters are disease-oriented and cover all relevant imaging modalities, with a focus on magnetic resonance imaging and computed tomography. The book also includes a synopsis of pediatric imaging. IDKD books are rewritten (not merely updated) every four years, which means they offer a comprehensive review of the state-of-the-art in imaging. The book is clearly structured and features learning objectives, abstracts, subheadings, tables and take-home points, supported by design elements to help readers navigate the text. It will particularly appeal to general radiologists, radiology residents, and interventional radiologists who want to update their diagnostic expertise, as well as clinicians from other specialties who are interested in imaging for their patient care.

The second edition of this reference features more than 300 high-quality color illustrations to assist practicing veterinarians and veterinary students in identifying small animal ear diseases. It begins with a review of the science involved in diagnosing and treating ear disease, including the anatomy of the ear, examination techniques, and pathophysiology. Coverage also includes discussions of specific ear disease conditions, based on the standard ear disease classification scheme of predisposing factors, primary causes, and perpetuating factors. The consistent presentation of each disorder includes an introduction, color illustrations of the condition, description of diagnostic techniques, treatment options, suggested readings, and updated references. - More than 300 high-quality images illustrate a variety of ear conditions to assist practitioners in practical diagnosis. - A comprehensive chapter on marketing ear care and otitis therapy includes strategies for successfully integrating these services into practice to offer expanded patient services and increase profits. - A chapter on diagnostic imaging provides the latest information on using imaging to diagnose small animal ear disease. - An Ear Product Formulary in the appendix serves as a complete guide to products available for treating small animal ear diseases. - 6 new chapters covering: - The microbiology of the ear of the dog and cat Laser ear surgery Cytology of the ear in health and disease Adverse food reactions Diseases that affect the pinna Otitis interna and vestibular disease - Expanded coverage of otic cytology and a photographic manual of ear cytology - In-depth discussions of video otoscopic diagnostics - New photos of interesting cases contributed by practitioners

This constitutes one volume of Wood's Library of Standard Medical Authors, and its aim, as stated in the preface, is "to present, in text-book form, a picture of diseases of the ear as they have appeared to the author in hospital and private practice." Boston Medical and Surgical Journal 1881, 104::158 Feb. 17, 1881.
