Cochlear Implantation in Children with Inner Ear Malformation and Cochlear Nerve Deficiency


Book Description

The purpose of this book is to contribute to basic and clinical medical research on cochlear implants for inner ear malformation and cochlear nerve deficiency. Cochlear implantation for children is performed worldwide, and the outcomes concerning speech and hearing acquisition are epoch-making. However, there are some difficulties associated with applying this operative treatment to patients who have complicated inner ear malformations or cochlear nerve deficiencies that have slowed the development of their speech, hearing, and/or sense of balance. The first part of the book outlines the fundamental aspects of inner ear maldevelopment to facilitate readers’ understanding of cochlear implantation from the point of view of embryology, morphology, and genetics. In turn, the second part describes current clinical cases and presents successful clinical reports. The book offers a primary resource for otolaryngologists, neurologists, and pediatricians with an interest in this field.




Cochlear Implantation for Cochlear Nerve Deficiency


Book Description

Having been found in 3%-21% patients with congenital sensorineural deafness, cochlear nerve deficiency (CND) is defined by a small or absent cochlear nerve. This book describes the updated information on the embryology, pre- and post- operative auditory, electrophysiology and vestibular aspects of CND. What’s more, the cochlear implantation (CI) strategy and CI outcomes as well as comparison with normal patients will be discussed in details with selected cases and high resolution illustrations. It will be a valuable reference for otologists, audiologists and practitioners who would like to understand more about CND and choose optimal clinical strategy of CI surgery for CND.




Pediatric Cochlear Implantation


Book Description

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.

This book, in which experts from around the world have contributed, comprehensively covers advances in all aspects of hearing implantation otology. Chapters review the evidence behind the current applications of the wide range of hearing implants available for different types of hearing loss. Further articles discuss the extended applications of implantation otology and let us have a glimpse into the future of hearing rehabilitation. New imaging techniques for the middle and inner ear are explored as well as innovations to improve Eustachian tube function. The publication is essential reading to otolaryngologists, audiologists and hearing rehabilitation professionals. It provides comprehensive coverage of state of the art hearing rehabilitation across the spectrum of hearing loss: as such it is a perfect tool for those who wish to develop their knowledge within the field.




Cochlear Implantation for Common Cavity Deformity


Book Description

The common cavity deformity (CCD) of the inner ear is characterized by cochlea and vestibule forming a single cavity. It indicates cochlear implantation (CI) and about 15% to 25% of inner ear malformation. However, complications such as facial nerve injury, penetration of the electrode array into the internal auditory canal (IAC) and electrode displacement are common, leading to unsatisfied outcomes. This book describes the embryology of CCD, preoperative auditory, balance and vestibular evaluation, and electrophysiology and radiology aspect for CCD. In addition, the surgical technique and CI outcomes will be focused. The electrode array design is also a highlight for CCD surgery, and will be discussed in details. Last but not least, the balance and vestibular function research of CCD patients before and after surgery is also thoroughly reviewed. It will be a good reference for otologist and practitioners in related field to understand more about CCD.




Cochlear and Brainstem Implants


Book Description

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: Mechanisms, Prevention and Cure


Book Description

This book systematically discusses the pathogenesis, prevention, and the current and potential clinical treatment of hearing loss, as well as the latest advances in hearing research. Hearing loss is a prevalent sensory disorder, which according to a 2015 World Health Organization (WHO) report affected 9% of the global population in 2015. As populations continue to age, more and more people are suffering from the condition, with 60% of those aged between 65 and 75 affected. Hearing loss seriously affects patients’ ability to work ability and quality of life, and as such deafness has become an increasingly urgent social problem around the globe. Sensorineural hearing loss is mainly caused by damage to the hair cells (HCs), and the subsequent loss of spiral ganglion neurons (SGNs). Damage to the HCs in the inner ear can result from exposure to loud noises and environmental and chemical toxins as well as genetic disorders, aging, and certain medications. This book provides ENT specialists and researchers, as well as individuals affected a comprehensive introduction to the field of hearing loss.
