Filter by:This clinical investigation aims to collect data on the use of the Mi2000 system, a totally implantable cochlear implant system, for the first time in human subjects.
The goal of this project is to determine whether the selection of hearing aid settings should be based in part on an individual's cognitive characteristics (specifically, working memory). We anticipate the outcomes of this study to be applicable to realistic listening conditions.
The purpose of the study is to evaluate the long-term safety and effectiveness of cochlear implantation of the approved population in adults and children with single-sided deafness and asymmetric hearing loss.
More than 1/3 of adults in the United States seek medical attention for vestibular disorders and hearing loss; disorders that can triple one's fall risk and have a profound effect on one's participation in activities of daily living. Hearing loss has been shown to reduce balance performance and could be one modifiable risk factor for falls. Patients with vestibular hypofunction tend to avoid busy, hectic, visually complex, and loud environments because these environments provoke dizziness and imbalance. While the visual impact on balance is well known, less is known about the importance of sounds. In search for a possible mechanism to explain a relationship between hearing and balance control, some studies suggested that sounds may serve as an auditory anchor, providing spatial cues for balance, similar to vision. However, the majority of these studies tested healthy adults' response to sounds with blocked visuals. It is also possible that a relationship between hearing loss and balance problems is navigated via an undetected vestibular deficit. By understanding the role of auditory input in balance control, falls may be prevented in people with vestibular disorders and hearing loss. Therefore, there is a critical need for a systematic investigation of balance performance in response to simultaneous visual and auditory perturbations, similar to real-life situations. To answer this need, the investigators used recent advances in virtual reality technology and developed a Head Mounted Display (HMD) protocol of immersive environments, combining specific manipulations of visuals and sounds, including generated sounds (i.e., white noise) and real-world recorded sounds (e.g., a train approaching a station). This research will answer the following questions: (1) Are sounds used for balance and if yes, via what mechanism? (2) Do individuals with single-sided hearing loss have a balance problem even without any vestibular issues? (3) Are those with vestibular loss destabilized by sounds? To address these questions, the following specific aims will be investigated in individuals with unilateral peripheral vestibular hypofunction (n=45), individuals with single-sided deafness (n=45), and age-matched controls (n=45): Aim 1: Establish the role of generated and natural sounds in postural control in different visual environments; Aim 2: Determine the extent to which a static white noise can improve balance within a dynamic visual environment.
The purpose of this study is to evaluate the efficacy of OpenSound Navigator (OSN), a hearing aid speech-enhancement algorithm developed by Oticon, as treatment for pediatric hearing aid users. The study used a within-subjects design with pre- and post-comparisons involving fifteen pediatric (ages 6-12) patients with symmetrical sensorineural hearing losses ranging from the mild to moderately-severe degree. All participants were fit with bilateral Oticon OPN™ behind-the-ear hearing aids set with the OSN algorithm enabled. The investigators evaluated hearing aid benefit through word recognition in noise (behavioral testing) and everyday hearing/listening abilities (parental/legal guardian reported) within one week of the hearing aid fitting (pre-intervention) and two months post fitting (post-intervention).
The purpose of this study is to determine whether a scleral buckling surgical procedure performed on fellow eyes of patients with genetically confirmed Stickler syndrome can prevent the occurrence retinal detachment and/or severe vision loss of the study eye.
This is a randomized, double-blind study of PIPE-505, or placebo, in subjects with hearing loss associated with speech-in-noise impairment.
A newly developed MED-EL Cochlear Implant incorporates the anti-inflammatory agent dexamethasone (DEX) into the electrode array. The passive elution of DEX during the post-implantation period has the purpose of counteracting the increase of the post-operative impedance induced by the insertion trauma. The aim of this clinical investigation is to obtain a first experience in use of the investigational device in the adult clinical population, and to initially assess tools, techniques and performance outcome measures that may be considered in future clinical studies of similar devices.
The Bonebridge system using the BCI 601 is marketed since 2012. Previous prospective, multi-center, non-randomized studies on the BCI 601 Bonebridge performed in adult and paediatric populations have shown a significant improvement in terms of aided sound field (SF) thresholds, word recognition scores (WRS), speech reception thresholds (SRT) and subjective device satisfaction. Safety was established by stable residual hearing and low complication rates. The Bonebridge, implanted in over 600 clinics worldwide, is the world's first active transcutaneous bone conduction implant (BCI) system. This study now focuses on the further developed BCI 602 (marketed since 2019) that has the same indication criteria and performance characteristics. The aim of this post-market clinical follow-up (PMCF) study is to provide clinical data for the long-term performance and safety when implanted with the Bonebridge BCI 602 .
Adults with CF regularly receive anti-infective therapy that can result in impaired hearing. Recent studies have identified that up to 50% of adults with CF have hearing loss with resulting significant impact on quality of life. At present, however, there is no national recommendation to screen for hearing loss within adult CF. Formal hearing tests are costly, require specialist staff and equipment and require further outpatient visits resulting in significant impact on health, social and financial resource. We propose to analyse over a 12 month period at two adult cystic fibrosis centres in London whether outpatient tablet based audiometry testing and web-based hearing apps are able to accurately screen for ototoxicity in adults with CF, and whether these methods of screening are acceptable. The results of this study will aim to streamline audiometry screening to improve detection rates, reduce cost of healthcare, enable equity in service delivery, and minimize disruption to the patient's social and work-life using smart technology.
