Book Description
Improved cochlear implant (CI) designs and surgical techniques have allowed CI patients to retain acoustic hearing in the implanted ear post-operatively. These EAS (electric-acoustic stimulation) CI users listen with a combination of acoustic and electric hearing in the same ear. While electric hearing alone improves speech recognition in quiet, preserved acoustic hearing allows EAS CI users to outperform traditional CI users in speech recognition in noise and demonstrate "speech masking release," an improvement in speech recognition in temporally fluctuating noise relative to steady noise. Masking release is arguably an ecologically valid metric, as listeners often attend to target speech embedded in fluctuating competing speech. Improved speech recognition outcomes have been attributed to the spectral and temporal resolution provided by acoustic hearing. However, the relationship between spectral and temporal resolution and outcomes in EAS CI users is not clear. This study evaluated speech masking release, spectral ripple density discrimination thresholds, and fundamental frequency difference limens (f0DLs) in EAS CI users. Both the ripple and f0DL tasks are thought to measure underlying spectral resolution and temporal fine structure. EAS CI subjects underwent testing in three listening modes: acoustic-only, electric-only, and acoustic+electric. Comparisons across listening modes allowed the benefit provided by acoustic hearing to be quantified. It was hypothesized that speech masking release, spectral ripple density discrimination thresholds, and f0DLs would be poorest with electric-only hearing and would improve in the acoustic-only and acoustic+electric listening modes. This would reflect the benefit of preserved acoustic hearing. It was also hypothesized that speech masking release would correlate with spectral ripple density discrimination thresholds and f0DLs, reflecting the roles of spectral and temporal fine structure cues.

Book Description
Not all cochlear implant cases present in a traditional manner, which calls for audiologists to seek a second opinion in more intricate and difficult cases. Complex Cochlear Implant Cases: Management and Troubleshooting offers both new and experienced cochlear implant audiologists the opportunity to tap into the knowledge and experience of skilled colleagues who have handled unique and challenging clinical situations with current or potential implant recipients. The book includes pediatric and adult complex cases pertaining to issues in mapping because of various medical conditions, equipment issues, improper device programming, lack of objective methods, and more. Each case starts with a clinical presentation, audiological testing, device programming, and suggested reading with research-backed references. The addition of questions for the reader offers time for the clinician to work through the case in their mind before providing answers, insights, summary, and key points. In addition to cases, the book also includes information on common methods for troubleshooting, objective measures, and instruction, as well as supplemental information regarding programming electrical-acoustic stimulation (EAS) cochlear implants. Key Features: * Includes pediatric and adult complex cases * Cases are descriptive and offer highly illustrative insights * Cases written by experienced cochlear implant audiologists working in high-volume cochlear implant centers in hospital and university settings * 125+ figures including audiograms, mapping, and objective measures provide a visual representation to each case, helping the reader rationalize recommendations from leaders in the field "In this book you'll be exposed to a variety of complex cases that will help you improve your clinical skills. You'll learn about practices that clinicians use to alleviate problems and improve outcomes. Some of these practices are standard while many are unique steps you may never have considered." –Terry Zwolan, PhD, CCC-A, Clinical Professor Emerita, Department of Otolaryngoloay, Head & Neck Surgery, Michigan Medicine, Universtiy of Michigan, Ann Arbor

Book Description
This updated second edition of Cochlear Implant Patient Assessment, Evaluation of Candidacy, Performance, and Outcomes, Second Edition is an instrumental reference for clinicians working with cochlear implant recipients and graduate students in the fields of speech-language pathology and audiology. The content of the text is logically organized, and begins with necessary background information for cochlear implant candidacy and the selection process. Later chapters provide information on assessment of implant candidacy, postoperative assessment of performance over the long term, and possibilities for future research and understanding. Though Cochlear Implant Patient Assessment, Second Edition contains useful information for even the most seasoned clinicians, it will serve an especially important role in the education and training of students and clinicians being introduced to cochlear implant clinical practice. Having an experienced audiologist and speech-language pathologist authoring this work unites the inter-disciplinary nature of this practice. New to the Second Edition: * Up-to-date research guiding candidacy and outcomes assessment—particularly relevant for cases of hearing preservation, determining bilateral CI candidacy, bimodal hearing, and assessment of the nontraditional cochlear implant candidate * Assessment of candidacy and postoperative outcomes for individuals with unilateral deafness * Assessment of non-English-speaking patients * Role of imaging in device selection and postoperative assessment Disclaimer: Please note that ancillary content (such as documents, audio, and video, etc.) may not be included as published in the original print version of this book.

Book Description
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.
