Cochlear Prostheses

Cochlear implants have instigated a popular but controversial revolution in the treatment of deafness. This book discusses the physiological bases of using artificial devices to electrically stimulate the brain to interpret sounds. As the first successful device to restore neural function, the cochlear implant serves as a model for research in neuroscience and biomedical engineering. These and other auditory prostheses are discussed in the context of historical treatments, engineering, psychophysics and clinical issues as well as implications for speech, behavior, cognition and long-term effects on people.

Today cochlear implants are the most successful of all prostheses of the nervous system. They are used in individuals who are deaf or suffer from a severe hearing deficiency caused by loss of cochlear hair cells. Auditory brainstem implants provide stimulation of the cochlear nucleus and are used in patients with an auditory nerve dysfunction, a deformed cochlea which does not allow cochlear implantation, or traumatic auditory nerve injury. In this volume different aspects of cochlear implantation such as the role of neural plasticity, the interaction with the development of the auditory system, and the optimal time of implantation in children (sensitive periods) are discussed in detail. Further, the processors and the algorithms used in modern cochlear implants are described The second part is devoted to auditory brainstem implants. It describes surgical techniques, methods for intraoperative testing as well as speech processing. It also deals with electrical stimulation of neural tissue and the neurophysiologic basis for cochlear and brainstem implants. The publication provides the latest scientific and clinical knowledge on cochlear and brainstem implants and is highly recommended to audiologists, otolaryngologists and also neurosurgeons.

The cochlear implant is a device that bypasses a nonfunctional inner ear and stimulates the auditory nerve directly. Written by the "father" of the multi-electrode implant, this comprehensive text and reference gives an account of the principles underlying cochlear implants and their clinical application. For the clinician, the book will provide guidance in the treatment of patients; for the engineer and researcher it will provide the background for further research; and for the student, it will provide a through understanding of the subject.

The second edition of Cochlear Implants provides a comprehensive review of the state-of-the-art techniques for evaluating and selecting the cochlear implant candidate. Clear descriptions of surgical techniques guide the reader through implantation procedures, and chapters address important issues such as speech production, language development, and education in implant recipients. This second edition features: New chapters on the genetics of hearing loss, sound processing, binaural hearing, and electroacoustic stimulation Complete discussion of the most recent advances in evaluation procedures, surgery, programming methods, speech processing strategies, and more Precise, easy-to-follow tables and figures enhance comprehension of the basic science, research and clinical concepts covered in the text Coverage of the medical and surgical complications of cochlear implantation Insights from an interdisciplinary team of experts in otolaryngology, audiology, the basic sciences, speech pathology, and education Ideal for learning and reference, Cochlear Implants synthesizes the key information needed by practitioners, researchers, and students in a range of disciplines. Readers will benefit from both the scope and thoroughness of this authoritative reference.

Cochlear Implants: Audiologic Management and Considerations for Implantable Hearing Devices provides comprehensive coverage of the audiological principles and practices pertaining to cochlear implants and other implantable hearing technologies. This is the first and only book that is written specifically for audiologists and that exhaustively addresses the details involved with the assessment and management of cochlear implant technology. Additionally, this book provides a through overview of hybrid cochlear implants, implantable bone conduction hearing technology, middle ear implantable devices, and auditory brainstem implants. Key Features: Each chapter features an abundance of figures supporting the clinical practices and principles discussed in the text and enabling students and clinicians to more easily understand and apply the material to clinical practice.The information is evidence based and whenever possible is supported by up-to-date peer-reviewed research.Provides comprehensive coverage of complex information and sophisticated technology in a manner that is student-friendly and in an easily understandable narrative form.Concepts covered in the narrative text are presented clearly and then reinforced through additional learning aids including case studies and video examples.Full color design with numerous figures and illustrations. Cochlear Implants is the perfect choice for graduate-level courses covering implantable hearing technologies because the book provides a widespread yet intricate description of every implantable hearing technology available for clinical use today. This textbook is an invaluable resource and reference for both audiology graduate students and clinical audiologists who work with implantable hearing devices. Furthermore, this book supplements the evidence-based clinical information provided for a variety of implantable hearing devices with clinical videos demonstrating basic management procedures and practices.

Thoroughly updated for its Second Edition, this book provides an in-depth discussion on prosthetic restoration of hearing via implantation. The text succinctly discusses the scientific principles behind cochlear implants, examines the latest technology, and offers practical advice on how to assess candidates, how to implant the devices, and what rehabilitation is most effective. The authors thoroughly examine the outcomes of cochlear implantation, the impact on the patient's quality of life, the benefits in relation to the costs, and the implications of cochlear implants for language and speech acquisition and childhood education.

Cochlear implants are currently the standard treatment for profound sensorineural hearing loss. In the last decade, advances in auditory science and technology have not only greatly expanded the utility of electric stimulation to other parts of the auditory nervous system in addition to the cochlea, but have also demonstrated drastic changes in the brain in responses to electric stimulation, including changes in language development and music perception. Volume 20 of SHAR focused on basic science and technology underlying the cochlear implant. However, due to the newness of the ideas and technology, the volume did not cover any emerging applications such as bilateral cochlear implants, combined acoustic-electric stimulation, and other types of auditory prostheses, nor did it review brain plasticity in responses to electric stimulation and its perceptual and language consequences. This proposed volume takes off from Volume 20, and expands the examination of implants into new and highly exciting areas. This edited book starts with an overview and introduction by Dr. Fan-Gang Zeng. Chapters 2-9 cover technological development and the advances in treating the full spectrum of ear disorders in the last ten years. Chapters 10-15 discuss brain responses to electric stimulation and their perceptual impact. This volume is particularly exciting because there have been quantum leap from the traditional technology discussed in Volume 20. Thus, this volume is timely and will be of real importance to the SHAR audience.
