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.

Hearing loss is one of the leading contributors to the global disease burden. In particular, the increasing population of people aged 65 years and older is expected to be a key driver. In children, hearing screening programs are becoming a worldwide standard, improving auditory rehabilitation options from a very young age. Implantable auditory technology–which, apart from cochlear implants, includes auditory brainstem implants, bone anchored hearing aids, and implantable middle ear devices–is an emerging field, and these devices represent a new era in hearing rehabilitation. However, cochlear implantation is still the biggest segment in the hearing implants market. Cochlear implantation is performed in a growing number of patients worldwide, and the indications are widening, helped by technological advances. 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 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.


Its Physiology and Pathophysiology

There is a new trend in the education of audiologists that emphasizes the basics of hearing--Hearing: Its Physiology and Pathophysiology addresses this trend. It covers not only the basics of hearing but also the basics of pathophysiology, which is not covered in a comprehensive way in any other text today. This book recognizes the fact that the diseased auditory system does indeed function, but in a different way than the normal system. Few books have addressed the pathophysiology of the ear and the auditory nervous system. Most books on hearing begin with a detailed description of the physics of sound, which scares many readers away because they believe they need to understand acoustics to understand how the ear functions. Hearing: Its Physiology and Pathophysiology does not assume that the readers are physicists, which would be analogous to assuming that visual physiologists would need to know quantum mechanics to understand how the visual nervous system functions. * This book provides a thorough understanding of the anatomy and function of the auditory system * To the basic scientist, it will provide an understanding of the auditory system and how it works * To the clinician, it will provide insight into the normal and diseased auditory system

Hearing loss can vary in type ranging from conductive, mixed to sensorineural, as well as in degree from mild, moderate, severe to profound. There could also be multiple permutations and combinations like moderate mixed hearing loss or severe conductive hearing loss. In addition, the hearing loss could be unilateral or bilateral. While cochlear implants were devised for bilateral profound sensorineural hearing loss, various other devices have been invented for other types of hearing losses. Research continues to design a suitable implant which would amplify sound for patients who cannot be candidates for cochlear implants.

Traumatic Brain Injury (TBI) can lead to loss of skills and to mental cognitive behavioural deficits. Paraplegia after Spinal Cord Injury (SCI) means a life-long sentence of paralysis, sensory loss, dependence and in both, TBI and SCI, waiting for a miracle therapy. Recent advances in functional neurosurgery, neuroprosthesis, robotic devices and cell transplantation have opened up a new era. New drugs and reconstructive surgical concepts are on the horizon. Social reintegration is based on holistic rehabilitation. Psychological treatment can alleviate and strengthen affected life. This book reflects important aspects of physiology and new trans-disciplinary approaches for acute treatment and rehabilitation in neurotraumatology by reviewing evidence based concepts as they were discussed among bio and gene-technologists, physicians, neuropsychologists and other therapists at the joint international congress in Brescia 2004.

The brain is plastic and it can change its function to adapt to changing demands of various kinds. The brain can also re-organize and change its function to better utilize its resources when parts of the brain have been damaged through injuries and diseases. This means that the brain is not “hard wired but can be reprogrammed when needed. This book describes different aspects of how the plasticity can become activated and how it can benefit the individual person. This book provides in-depth coverage of many important aspects of neural plasticity and how it applies to trauma, including strokes and disorders of the central nervous system that affect memory and cognition. The book also discusses how neural plasticity is involved in aphasia, pain and tinnitus. The roles of neural plasticity in motor rehabilitation and in adaptation to prostheses such as cochlear and cochlear nucleus implants are also topics of the book. * Provides in-depth coverage of many important aspects of neural plasticity and how it applies to trauma, including strokes and disorders of the central nervous system that affect memory and cognition * Discusses how neural plasticity is involved in aphasia, pain and tinnitus * Explains the roles of neural plasticity in motor rehabilitation and prosthesis such as cochlear and cochlear nucleus implants

Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.
