Filter by:Main objective: Compare the recognition of environmental sounds with an anatomy-based fitting and with a default fitting adult patients newly implanted with a MED-EL cochlear implant. Secondary objectives: Compare speech recognition in quiet with an anatomy-based fitting and with a default fitting in adult patients newly implanted with a MED-EL cochlear implant. Compare speech recognition in noise with an anatomy-based fitting and with a default fitting in adult patients newly implanted with a MED-EL cochlear implant.
The goal of the present study is to use computationally driven models of speech understanding in CI users to guide the search for which combination of active electrodes can yield the best speech understanding for a specific patient. It is hypothesized that model-recommended settings will result in significantly better speech understanding than standard-of-care settings.
Fibrosis due to surgical trauma is a common problem with cochlear implants. Fibrosis limits the effectiveness of implant and increases the power consumption. Our aim in this study is to benefit from the anti-inflammatory effects of autologous platelet-rich fibrin to reducing the fibrotic cascade.
Project synopsis: This prospective cohort study investigates impact of (1) hearing loss and (2) cochlear implantation on cost and health state on one hand, and employment, productivity and social wellbeing on the other hand in a professionally active group using validated questionnaires. Participants: The investigators aim to include 100 professional active adults between 18 and 65 years old. All participants have a bilateral severe-to-profound sensorineural or mixed hearing loss. Due to several reasons such as an optimal hearing aid fitting, the presence of a residual hearing or physical contra-indications, half of these participants will not be implanted with CI. Additionally, 100 participants with a single-sides deafness (SSD) in the acute or chronic setting (SDD present for at least three months) will be included. Study design Study measures: All audiological tests and patient-reported outcome measures will be included in this test protocol and repeated throughout the follow-up visits depending on aided or unaided setting. The cognitive evaluation will be executed during the first and last test moment. The investigators anticipate that the protocol will take 1 hour per follow-up in the hospital (audiological testing and to go over the questionnaires), plus an extra hour at home to fill out the questionnaires. For the cognitive tests, an extra hour in the hospital will be scheduled. Hypothesis As a primary endpoint, the investigators anticipate demonstrating that severe-to-profound hearing loss has a significant impact on sick leave and self-reported productivity. Health state will also be analyzed as a secondary endpoint because the investigators anticipate only marginal improvement (if any) on these instruments due to the lack of sensitivity and responsiveness, even in this population. The investigators will also determine the rate of usage and non-usage at this long-term follow-up to demonstrate the utility of cochlear implants. Statistical analysis IBM SPSS Statistics (IBM; Armonk, NY) will be used for the statistical analyses. The participants' hearing profiles will be summarized using descriptive statistics (median, and range). In view of the sample size, non-parametric tests and linear mixed models (to describe evolution in time and difference between groups) will be used. Quantitative data will be presented as median and range (minimum and maximum). Descriptives will be used to summarize the outcomes of the subjective data logging. For the speech perception in noise results, a Wilcoxon signed-rank test will be used. In addition, to correct for the multiple speech in noise test configurations, Holm's correction will be applied. The level of significance will be set at p.0.05. Data storage REDCap (Research Electronic Data Capture) is a secure, web-based application designed exclusively to support data capture for research studies. REDCap provides an interface for data entry (with data validation) and audit trails for tracking data manipulation and export procedures. Data will be pseudomized before storage in REDCap.
The proposed study will investigate whether an auditory brain training program can improve cochlear implant (CI) outcomes in older post-lingually deafened CI users. The study will evaluate the potential benefit of training on speech recognition performance, psychosocial and cognitive function.
One common side effect of cisplatin chemotherapy is ototoxicity. The drugs sodium thiosulfate and mannitol may protect against cisplatin-induced hearing loss. Specifically, sodium thiosulfate has been found to protect the cells in the inner ear, and may therefore prevent hearing loss. Mannitol can help sodium thiosulfate enter the inner ear, and ponteially increase the effectiveness of sodium thiosulfate. This study aims to assess the efficacy of sodium thiosulfate and mannitol to reduce the hearing impairment caused by cisplatin chemotherapy.
The objective of this study is to examine the effects and safety of Liuwei Dihuang pill and placebo in presbycusis with Shen (kidney)-yin deficiency.
This research is being done to determine whether a test that measures a "Visual Evoked Potential" can be used in a new way for individuals that have hearing loss. This test measures the participant's brain's response (so called "brain waves") to specific visual images. This study will help the investigators determine whether this test could be used to improve treatments for patients with hearing loss. The "Visual Evoked Potential" measurement test is already used in the investigator's Neurology clinic at Dartmouth Hitchcock Medical Center for various conditions to measure "early" brain responses that occur in the first 1-2 seconds after a new cue. Our research aims to explore your brain's response just after that early 1-2 second period by looking at a specific response called the "P300". The P300 wave is a brain response to new or different images or sounds. A visual evoked P300 has not been studied in individuals with hearing loss. The investigators will compare the results of this test to standard auditory tests, tests of cognitive function, and cochlear implant patient outcomes to explore how these factors can predict successful use of a hearing aid or cochlear implant.
Hearing impairment in older adults is becoming a common health problem as the population ages. The impact of hearing impairment in older adults includes not only physical function and cognitive performance, but also depression, loneliness and social isolation, as well as having a negative impact on quality of life and financial status. Therefore, an audiological rehabilitation program intervention is recommended. The purposes of this study are to examine the effects of an audiological rehabilitation program (Hear-Talk-Activity audiological rehabilitation program) intervention on communication abilities, depression, loneliness and quality of life outcomes in older adults with hearing impairment. The single-blind, randomized control trial will include older adults aged 65 years or older with hearing impairment and aid user. Participants will be randomized to either intervention groups or control groups.
Prospective 2-arm cohort consisting of a preoperative visit and visits at the time of implantation (Day 0) and follow-up in patients for whom their treating physician indicated a perimodiolar or straight cochlear implant.
