We conducted an analysis to assess the relative contribution of auditory brainstem response (ABR) testing and auditory steady-state response (ASSR) testing in providing appropriate hearing aid fitting in hearing-impaired children with difficult or unreliable behavioral audiometry. Of 150 infants and children who had been referred to us for hearing assessment as part of a neonatal hearing screening and cochlear implantation program, we identified 5 who exhibited significant discrepancies between click-ABR and ASSR testing results and difficult or unreliable behavioral audiometry...

Currently, there are no studies assessing everyday use of cochlear implant (CI) processors by recipients by means of objective tools. The Nucleus 6 sound processor features a data logging system capable of real-time recording of CI use in different acoustic environments and under various categories of loudness levels. In this study, we report data logged for the different scenes and different loudness levels of 1,366 CI patients, as recorded by SCAN. Monitoring device use in cochlear implant recipients of all ages provides important information about the listening conditions encountered in recipients' daily lives that may support counseling and assist in the further management of their device settings...

BACKGROUND: Persistent dizziness symptoms after cochlear implantation have an impact on quality of life. In this study, the effects of bilateral cochlear implants (CI) on quality of life as well as on subjective dizziness complaints are analyzed using questionnaires, some of which have never been applied before in these patient collectives. OBJECTIVE: In this article, questionnaires for the assessment of dizziness symptoms and quality of life are introduced in order to realize quality assurance...

Speech intelligibility, or how well a speaker's words are understood by others, affects listeners' judgments of the speaker's competence and personality. Deaf cochlear implant (CI) users vary widely in speech intelligibility, and their speech may have a noticeable "deaf" quality, both of which could evoke negative stereotypes or judgments from peers. In this study, college students with typical hearing (TH) used semantic differential scales to rate speech samples of highly-intelligible TH young adults and age-matched CI users with high or low intelligibility (CI-Hi, CI-Lo) on personality traits related to competence (intelligence, achievement), friendship skills (friendliness, popularity), and attractiveness as a friend (extraversion, dependability)...

HYPOTHESIS: Microtopographical patterns generated by photopolymerization of methacrylate polymer systems will direct growth of neurites from adult neurons, including spiral ganglion neurons (SGNs). BACKGROUND: Cochlear implants (CIs) provide hearing perception to patients with severe to profound hearing loss. However, their ability to encode complex auditory stimuli is limited due, in part, to poor spatial resolution caused by spread of the electrical currents in the inner ear...

OBJECTIVE: Biomarkers reflecting the etiology and pathophysiology of inner ear diseases are limited. Evaluation of proteins in the perilymph may improve our understanding of inner ear disease. Heat shock proteins (HSP) belong to a superfamily of stress proteins and promote refolding of denatured proteins. The aim of the study was to analyze HSP in human perilymph and to identify possible correlation with audiological and etiologic data. METHODS: Sampling of the perilymph was performed during cochlear implantation and vestibular schwannoma removal...

OBJECTIVE: Determine the change in general health-related quality of life (HRQOL) after cochlear implantation and association with speech recognition. STUDY DESIGN: Meta-analysis. METHODS: Search was performed following the PRISMA statement using PubMed, Medline, Scopus, and CINAHL. Studies on adult cochlear implant (CI) patients measuring HRQOL before and after cochlear implantation were included. Standardized mean difference (SMD) for each measure and pooled effects were determined...

OBJECTIVES: Bilateral cochlear implants (CI) are the standard treatment for bilaterally deaf children, but it is unclear how much the second CI can be delayed in sequential bilateral CI. We investigated the performances of sequential CI to answer this question. STUDY DESIGN: Retrospective case series review. SETTING: Tertiary referral center. METHODS: We studied a cohort of congenitally deaf children (n = 73) who underwent sequential CI without any inner ear anomaly or combined disabilities...

OBJECTIVE: Children affected by hearing loss can experience difficulties in challenging and noisy environments even when deafness is corrected by Cochlear implant (CI) devices. These patients have a selective attention deficit in multiple listening conditions. At present, the most effective ways to improve the performance of speech recognition in noise consists of providing CI processors with noise reduction algorithms and of providing patients with bilateral CIs. The aim of this study was to compare speech performances in noise, across increasing noise levels, in CI recipients using two kinds of wireless remote-microphone radio systems that use digital radio frequency transmission: the Roger Inspiro accessory and the Cochlear Wireless Mini Microphone accessory...

A young bilateral cochlear implant (CI) user required magnetic resonance imaging (MRI) to determine the cause of hydrocephalus. The images obtained with the CIs in place were not diagnostically useful due to large artefacts generated by the CI magnets. We obtained useful images by bilaterally explanting the CI-magnets and replacing them with non-magnetic placeholder dummies then conducted the imaging. The artefact in the new images was greatly reduced and the images were diagnostically useful. Lastly, we explanted the dummies and reimplanted the CI-magnets...

OBJECTIVE: Personality psychology has largely ignored the experiences of people with disabilities. This paper strives to bring the thriving, interdisciplinary field of disability studies to personality psychology via a case study of Samantha (N=1). Samantha feels that she grew up as a hearing person who could not hear and is now a deaf person who can hear. METHOD: Narrative identity provides the theoretical, methodological, and analytical framework for the rich, qualitative examination of Samantha's life story, interwoven with approaches from disability studies and intersectionality theory...

OBJECTIVE: An amplitude growth function (AGF) shows the amplitude of an electrically evoked compound action potential (eCAP) as a function of the stimulation current. AGFs can be used to derive the eCAP threshold, which represents the minimum amount of current needed to elicit a measurable eCAP. eCAP thresholds have been widely used clinically to, for example, assist with sound processor programming. However, no eCAP precision has been included to date. The aim of this study was to investigate the precision of eCAP thresholds and determine whether they are precise enough for clinical use...

OBJECTIVE: Although speech perception tests are available to evaluate hearing, there is no standardized validated tool to quantify speech quality. The objective of this study is to develop a validated tool to measure quality of speech heard. STUDY DESIGN: Prospective instrument validation study of 35 normal hearing adults recruited at a tertiary referral center. METHODS: Participants listened to 44 speech clips of male/female voices reciting the Rainbow Passage...

OBJECTIVE: Electrically evoked auditory steady-state responses (EASSRs) are potentially useful for objective cochlear implant (CI) fitting and follow-up of the auditory maturation in infants and children with a CI. EASSRs are recorded in the electro-encephalogram (EEG) in response to electrical stimulation with continuous pulse trains, and are distorted by significant CI artifacts related to this electrical stimulation. The aim of this study is to evaluate a CI artifacts attenuation method based on independent component analysis (ICA) for three EASSR datasets...

OBJECTIVE: To examine practice variance of cochlear implant candidacy assessment and off-label indications across centers in the United States. METHODS: Cross-sectional survey of the American Neurotology Society (ANS). RESULTS: A total of 81 surveys were returned from ANS members who report regular involvement in cochlear implant care.
