Filter by:In this study Triamcinolone acetonide will be applied intratympanically before cochlear implant surgery. After round window exposure, a perilymph sample and simultaneously a blood sample will be drawn. Triamcinolone levels will then be analyzed in the samples.
The purpose of this investigation is to expand FDA-approved labeling for MED-EL cochlear implants to include adults who have moderate to profound sensorineural hearing loss and obtain limited benefit from appropriately fit hearing aids.
Listening with a cochlear implant remains difficult and most listeners will report high levels of listening effort.The present study is a "pilot" aiming to evaluate listening effort for cochlear implant users. The listening effort is measured with pupillometry, by monitoring the variations of pupil size in response to different stimuli. The size of the pupil is known to increase with the listening effort. The listening effort is evaluated in two different situation: speech perception in quiet and speech perception in noise. The pupillometry measures will be compared for the two listening conditions. Moreover, the study will evaluate the relationship between objective (pupil dilatation) and subjective measures (auto evaluation) of listening effort, and between speech comprehension, cognitive abilities and listening effort.
The purpose of this study is to investigate speech understanding in simulated reverberant environments with MED-EL cochlear implant recipients.
The main purpose of this study is to monitor the response from the cochlea as the electrode is inserted during the operation to receive a cochlear implant. The Cochlear Response Telemetry tool aims to measure the response from the cells within the cochlea and may be useful in the future to help to improve the surgical technique and potentially help surgeons better preserve any natural hearing that is available. The measurements are obtained using the cochlear implant and sound processor while a sound is presented to the ear through an earphone (like an earplug) placed into the ear canal.
The purpose of this study is to assess the benefit of new super-power bone-anchored hearing aid (BAHA) processors in BAHA users. BAHAs are able to help people with mixed/conductive and single-sided hearing loss when they are unable to use or receive limited benefit from traditional hearing. Until recently, BAHAs were only recommended to people with up to a moderate hearing loss. New super-power BAHA processors may be able to help people who previously were not candidates for BAHAs or received limited benefit from them. The information collected in this study may lead to improved evaluation of and expanded treatment options for people considering BAHA. Different types of hearing tests will be used to compare the devices.
Sensorineural type of hearing loss is the most common sensory deficit among older adults. Some of the psychosocial consequences of this condition include difficulty in understanding speech, depression and social isolation. Studies have shown that older adults with hearing loss show some age-related cognitive decline. There is no clinically proven method to predict the onset of this condition, as its occurrence is slow and progressive, affecting both ears equally. Although hearing aid use and auditory training have been proven as successful interventions to alleviate sensorineural hearing loss, no research has been designed to look at the effect of both hearing aid use coupled with auditory training on cognitive performance in older adults. This study will investigate whether wearing hearing aids will improve the impact of auditory training on cognition, mood and social interaction for older adults with sensorineural hearing loss. This is a crossover trial targeting older adults between 50 and 90 years with either mild or moderate symmetric sensorineural hearing loss. Consented, willing participants will undergo a six month intensive auditory training program (active control), as a rigorous means of examining the impact hearing aid use has on a person's cognition, mood and social interaction. Participants will be assigned in random order to receive hearing aid (intervention) for either the first three or last three months of the six month auditory training program. Each participant will be tested at baseline, three and six months on a battery of computer based cognitive assessments, together with mood, and social engagement measures. Effectiveness of hearing aids and auditory training will be evaluated using an online speech perception test (SPT) and the Abbreviated Profile of Hearing Aid Benefit (APHAB) Inventory. This study will investigate whether using a hearing aid coupled with auditory training can improve a person's cognition and learning abilities, relationships with family and friends, and quality of life. Results from the study will inform strategies for aural rehabilitation, hearing aid delivery and future hearing loss intervention trials.
The overall goal of this study is to determine the clinical benefit and safety of antiviral therapy for asymptomatic congenital cytomegalovirus (cCMV) infected hearing-impaired infants. We will conduct a multi-center double-blind randomized placebo-controlled trial to determine whether hearing-impaired infants with asymptomatic cCMV have better hearing and language outcomes if they receive valganciclovir antiviral treatment. We will also determine the safety of antiviral valganciclovir therapy for asymptomatic cCMV-infected hearing impaired infants. This study will be unique in that the cohort enrolled will only include hearing-impaired infants with asymptomatic cCMV. Primary Objective: To determine if treatment of cCMV-infected hearing impaired infants with isolated hearing loss with the antiviral drug valganciclovir reduces the mean slope of total hearing thresholds over the 20 months after randomization compared to untreated cCMV-infected infants with isolated hearing loss. Main Secondary Objectives: 1. To determine if valganciclovir treatment improves the following outcomes when compared to the control group: 1. The slope of best ear hearing thresholds over the 20 months after randomization. 2. The MacArthur-Bates Communicative Development Inventory (CDI) percentile score for words produced at 20 months of age. 2. To evaluate safety measures based on all grade 3 or greater new adverse events designated by the NIAID Division of AIDS (DAIDS) toxicity tables.
The Microtable® Microstereotactic Frame and Drill Press and Associated Method for Cochlear Implantation consists of a patient-customized microstereotactic frame which targets the cochlea. The intended use of the device in this early feasibility study is to surgically access the cochlea, allowing placement of an intra-cochlear electrode array for cochlear implantation, thereby providing a less invasive surgical option than currently performed. Compared to traditional cochlear implantation (CI) surgery, the investigators hypothesize that the minimally invasive, image-guided approach may offer the following benefits: (1) shorter procedure time including shorter general anesthesia time, (2) less tissue removal potentially eliminating post-operative mastoid bone depression, decreased post-operative patient discomfort, and quicker wound healing, (3) better chance of preservation of taste secondary to preservation of the chorda tympani nerve, and (4) standardization of electrode placement potentially allowing more consistent placement within the scala tympani sub-compartment of the cochlea which has been shown to be associated with improved post-operative audiological performance. This early feasibility study will focus on the advantages of the new technology to the patient. Advantages to the healthcare delivery system will be examined during the pivotal study phase.
