A Comparison Between Wireless CROS and Bone-anchored Hearing Devices for Single-Sided Deafness:...
Unilateral Hearing LossUnilateral DeafnessPeople with single-sided deafness (SSD) have significant hearing loss in one ear and normal or near normal hearing in the other ear. Those living with SSD experience several communication difficulties, particularly when listening to speech in the presence of background noise. This problem is worse in situations where the noise is on the side of the good ear and the speech is on the side of the poor ear. The Bone-anchored hearing device (BAHD) and the Contralateral Routing of Signals (CROS) hearing aid are two intervention methods designed to improve hearing in people who have significant hearing loss in one ear only. The BAHD is a surgically implanted device which also includes an external processor; sounds from the poor ear are transmitted to the good ear through skull vibrations. The CROS does not involve surgery; instead a hearing aid is fitted behind each ear, and the sounds on the side of the poor ear are wirelessly transmitted to the good ear. The majority of previous studies comparing the BAHD to the CROS have used older CROS models with basic technology and a wire along the neck to send sounds from the poor ear to the good ear. There is a lack of studies comparing newer digital wireless CROS hearing aids to the BAHD. The current research will compare the effect of the BAHD and CROS hearing aid on speech perception scores when listening to speech in quiet and in noise. The research will also investigate participants' reported benefits with each device during everyday situations. In order to compare the BAHD and CROS, individuals who already have been implanted with a BAHD will be given a trial period with a new wireless digital CROS hearing aid. The research hypothesis states that the CROS hearing aid will be as equally beneficial or greater than the BAHD in improving hearing and participant benefit. If the findings support the hypothesis that the CROS offers just as much benefits as the BAHD, or is an even better alternative, more individuals with SSD may choose to avoid surgery and decide to receive a CROS hearing aid instead.
A Study Of The Effects Of PF-04958242 In Subjects With Age-Related Hearing Loss
Hearing LossSensorineuralThe objective of this study is to examine the safety, tolerability, and effects on hearing thresholds of two single doses of PF-04958242 and placebo in subjects with age-related hearing loss.
Hearing Preservation Using Dexamethasone and Hyaluronic Acid for Cochlear Implantation
Hearing LossThe objective of the present study is to investigate the effect dexamethasone and hyaluronic acid have on hearing preservation
Stability of the Cochlear Baha BI300/BA400 Implant System Loaded From 1 Week Post-surgery
Hearing Loss - ConductiveObjectives To evaluate the safety of processor loading of the Cochlear BI300/BA400 implant system 1 week after implantation To evaluate the short term soft tissue healing and the long term skin reaction, with the new Cochlear BI300/BA400 implant system using the linear incision without subcutaneous tissue reduction. To produce reference data regarding the stability of the BI300/BA400 implant system. Study design: Prospective cohort study. Patients: 24 adults with anticipated normal skin and bone quality eligible for bone anchored implant surgery. Intervention: Loading of the sound processor one week after surgery Main outcome measures: Implant stability, soft tissue reaction, skin overgrowth, pain and numbness will be assessed. It is hypothesized that implant loading can be performed one week after surgery without any changes in implant stability, soft tissue reaction, skin overgrowth, pain or numbness around implant.
NAC to Prevent Cisplatin-induced Hearing Loss
Neuroectodermal TumorsPrimitive3 moreCisplatin is a key chemotherapy agent for the treatment of multiple childhood cancers but causes permanent hearing loss. This study investigates the drug N-acetylcysteine (NAC) to determine the dose necessary to protect hearing and also how well tolerated NAC is when combined with chemotherapy.
Clinical Assessment of the External Sound Processor Worn by Patients Implanted With Codacs
Severe to Profound Mixed Hearing LossThe purpose of this study is to evaluate the effect of the sound processor upgrade from the C-DACS investigational device Freedom sound processor to the Nucleus® CP810 sound processor for the Codacs™ system on the speech reception threshold in noise, to evaluate the usability of the Codacs™ Fitting Software, to evaluate the quality of life with the Nucleus® CP810 Sound Processor for the Codacs™ system, to collect long term data, to evaluate the acceptance criteria of the postoperative Codacs™ system test and to evaluate the usability of the Codacs™ Test System.
Outcomes In Children With Developmental Delay And Deafness
DeafnessHearing LossChildren with special needs require complex, individualized therapy to maximize their long-term quality of life. One subset of children with special needs includes those with both developmental delays and deafness. Currently, there is little compelling evidence supporting the idea that cochlear implantation provides benefit to children that don't have the cognitive potential to develop normal speech and language. We will perform a prospective, randomized clinical trial to answer the question of which intervention provides more benefit to this population of children using validated, norm-referenced tests. Our long-term goal is to develop guidelines that may help when selecting a treatment for hearing loss in a child with developmental delays. This proposal is significant because children with special needs are deserving of evidence upon which to base treatment decision-making, but remain under-represented in the medical literature and are often not studied. This research is designed to meet the criteria for the National Institutes of Health road map because it will generate this type of objective evidence that can directly improve patient care.
Pilot Study of the Feasibility and Efficacy of Working Memory Training in Children With Cochlear...
Bilateral Hearing LossThis study is an investigation of the effect of a computer-based working memory training program on memory and language processing in at-risk children (e.g., those with working memory weaknesses) who have received cochlear implants.
Safety and Efficacy of the Vibrant Soundbridge (VSB) for Mixed and Conductive Hearing Losses
Hearing LossThe purpose of this investigation is to collect feasibility data to assess the safety and efficacy of the Vibrant Soundbridge (VSB), a medical device designed to provide benefit in aided hearing thresholds, speech perception and sound quality to certain individuals with hearing loss with minimal changes in residual hearing. The VSB is currently indicated for adults with moderate-to-severe sensorineural hearing loss. Under the present investigation, adults with conductive and mixed hearing losses who are not successful users of traditional amplification will be assessed.
Supplementing Hearing Aids With Computerized Auditory Training
Hearing LossThe study is designed to examine the effectiveness of a computer-based auditory training program to improve the benefits received by individuals who wear hearing aids. The study will involve 3 groups - a computer-based training group, an active listening group which will involve listening to books on CD, and a placebo group that receives no additional treatment.
