Filter by:The aim of this retrospective study is to collect and assess hearing performance data that have been measured by five clinics in Germany as part of their clinical routine in recipients implanted with a commercial CI532.
Communication on telephone is challenging for people with hearing loss. For hearing aid users, for instance, the inventions for improving speech intelligibility on the phone range from an integrated tele coil and individual hearing programs to specially designed phone devices. No formal studies involving these devices have been carried out with CI users. Thus, this comparative study includes hearing aid as well as CI and bimodal users to evaluate different hearing solutions for communication on telephone in terms of intelligibility and ease of use.
The MED-EL EAS Extended Follow-up Study is an extended follow-up of the subjects who were enrolled in the pivotal study to assess long-term safety and device performance.
The purpose of this study is to gather long-term data on the FDA approved CI532 cochlear implant, and CP1000 (Nucleus 7) sound processor
Busy Primary Care providers (PCPs) have complex practices with many competing demands, making it difficult to improve their HL identification rates. Little research has been conducted to identify effective approaches to address the poor PCP knowledge and provide tools for them to better identify/refer patients with HL for appropriate intervention. Current data suggests there is a critical need to redesign how PCPs deliver hearing health care (HHC) by developing focused educational programs and simple clinical management tools to help them integrate HHC into their practices. To address this need, this study will educate providers on hearing loss (HL) screening/treatment as well as create a Best Practice Alert (BPA), or clinical prompt, that is configured for maximal effectiveness in reminding PCPs to ask their patients if they think they have a HL. This combination of education for providers and clinical reminder could help increase HL screening rates but how much is not clear. This 5 year R21/R33 study funded by National Institute of Deafness and Communicative Disorders seeks to provide detailed understanding of both how educating providers on HL and the use of an effective BPA affects HL screening rates and identification for people with mild to moderate hearing loss.
Alzheimer disease is a neurodegenerative disease. Recent studies suggest that subjects with hearing loss are more likely to develop Alzheimer's disease. Hearing loss can be consecutive to presbycusis and/or to central auditory dysfunction. Standard audiometric measures with pure tone and speech intelligibility allow the diagnosis of presbycusis. However, to demonstrate central auditory dysfunction, specific audiometric tests as noisy and/or dichotic tests, are needed. Actually, no consensus exists to investigate hearing loss in people with Alzheimer's disease; therefore hearing loss may be an early manifestation of Alzheimer's disease. Until now, investigations and clinical procedure related to the diagnosis of Alzheimer's disease ignored the hearing ability of the patient. However, the major part of care management and investigations implies the patient's communication ability with caregivers. Hearing loss may be one of the most unrecognized deficit in subjects with Alzheimer's disease. Auditory rehabilitation with hearing aids could benefit to the patient to decrease cognitive decline but this management must be investigate during longitudinal studies in order to demonstrate their efficiency and need to be compared with a placebo.
The ability to predict post-operative outcomes after implantation is important for a number of reasons, including being able to advise candidates of appropriate expectations using evidence based guidance. The approved study involves investigation of the ability to predict outcomes in the implanted ear alone and in the best-aided binaural listening conditions, examining a number of measured factors both pre-, peri- and post-operatively. The study incorporates a range of functional outcome measures through questionnaires to ascertain social, functional and demographic factors that may be predictive of outcomes. Questionnaires are also administered to determine the degree of benefit obtained after implantation for each individual, since this forms a key component of providing pre-operative counselling to candidates.
Recent studies have reported successful reduction of tinnitus after cochlear implantation (CI) in most CI users, but the mechanisms of reduction and the amount of improvement is not fully understood. Especially, the relative role of peripheral and central auditory pathways is not clearly known. This study assessed the effect of CI electrical stimulation on tinnitus in subjects with unilateral tinnitus related to a single-sided deafness (SSD), and relative contributions of peripheral and central auditory pathways in tinnitus reduction.
This feasibility study evaluates whether children with unilateral, moderate to profound sensorineural hearing loss experience an improvement in speech perception, hearing in noise, localization, and quality of life with a cochlear implant as compared to an unaided listening condition.
Twenty patients with tinnitus and a typical noise-induced hearing loss (NIHL) audiogram were included. Each subject underwent an otoscopic examination, distortion product otoacoustic emissions, tinnitus-match testing, Tinnitus Handicap Inventory (THI) and serum zinc level analyses. After 2 months of treatment with zinc, all tests were repeated.
