Cochlear And Brainstem Implants

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.

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.

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.

This is a comprehensive multi-author handbook covering all aspects of cochlear implantation, fully updated since its first edition was published in 1991. All aspects of this rapidly developing field are covered, from implant design, speech processing strategies, assessment and rehabilitation of children and adults to future developments. Chapters written by implant users and their parents give fascinating insight into the experience of hearing again with a cochlear implant.

This book will move the field of pediatric cochlear implantation forward by educating clinicians in the field as to current and emerging best practices and inspiring research in new areas of importance, including the relationship between cognitive processing and pediatric cochlear implant outcomes. The book discusses communication practices, including sign language for deaf children with cochlear implants and the role of augmentative/alternative communication for children with multiple disabilities. Focusing exclusively on cochlear implantation as it applies to the pediatric population, this book also discusses music therapy, minimizing the risk of meningitis in pediatric implant recipients, recognizing device malfunction and failure in children, perioperative anesthesia and analgesia considerations in children, and much more. Cochlear Implants in Children is aimed at clinicians, including neurotologists, pediatric otolaryngologists, audiologists and speech-language pathologists, as well as clinical scientists and educators of the deaf. The book is also appropriate for pre-and postdoctoral students, including otolaryngology residents and fellows in Neurotology and Pediatric Otolaryngology.

Introduction On behalf of the Organizing Committee of the Third Congress of Asia Pacific Symposium on Cochlear Implant and Related Sciences (3rd APSCI), I would like to extend my heartfelt thanks to all the attendants at the meeting, as well as to the contributors to these Proceedings. As most of you will have realized, the meeting was a great success both from a scientific as well as a social point of view. Almost four hundred attendants from 25 countries gathered in the Osaka Convention Hall. The program consisted of three parallel workshops spanning one and a half days, and three full days of scientific sessions. The weather was ideal, and our guests were able to see the cherry trees in full blossom and to enjoy their fill of Japanese culture. We have great pleasure in sending you your copy of the Proceedings of the 3rd APSCI, which contains all the updated information and state-of-the-art knowledge on cochlear implants and implantable hearing devices. As is indicated in the title of the meeting, this book covers many areas that are of scientific interest to us. The articles cover subjects ranging from surgical issues with regard to cochlear implantation, to basic studies on the auditory system, developmental studies in children, communication skills, speech, and education, etc. In addition, the reader will observe that some of the articles are related to implantable middle ear devices, a subject which was not covered in the proceedings of the 1st and 2nd APSCI meetings. The editors sincerely hope that this book will contribute to the development of cochlear implants and middle ear devices. Takeshi Kubo, MD President, 3rd APSCI

This comprehensive, high-level surgical reference and atlas is tailored for surgeons who are undertaking training for cochlear implant procedures and implantable auditory devices and for experienced surgeons who would like to expand their knowledge, improve their skills and outcomes, and learn advanced surgical techniques. Following the principle underlying Professor Sanna's other successful publications, Surgery for Cochlear and Other Auditory Implants takes an integrated approach to anatomy, imaging, technology, decision making, surgical procedures described step by step, and clinical cases. This book allows readers to: Improve the efficiency and outcomes of cochlear implantation and other auditory implant surgeries Learn the required basic and advanced surgical techniques Evaluate different surgical options and types of implants Review common and uncommon variations of anatomy and malformations Understand issues and surgical modifications unique to pediatric cochlear implantation, to revision surgery, and in postmeningitis, otosclerosis, and NF2 cases Find decision-making algorithms for difficult pathologies Examine common and not so common intraoperative dilemmas and identify strategies to resolve them Review preoperative assessment and set up and outcomes Find out about classification systems in cochlear implant failure, malformations, otosclerosis, and post meningitis Supplementing the 1200 images within the book are 15 outstanding videos available on Thieme's MediaCenter demonstrating the implantation of the different cochlear implantation devices that are currently available and the application of brainstem implants in these situations: tumor removal, malformation (missing auditory nerve in children), and cochlear ossification.
