Filter by:One of the main factors affecting the ability to maximize the full potential of a cochlear implant is an accurate map.The goal of mapping is to enable cochlear implant recipients to perceive a desired range of acoustic signals. The process includes programming of the minimum and the maximum stimulation levels that are based on subjective measurements of thresholds and the most comfortable level . The use of objective measures in the CI process has greatly contributed to the definition of the dynamic field, as they provide specific values that serve as the basis for the start of the mapping process, especially in cases of infants and young children. Some examples of these measures are electrically evoked stapedius reflex threshold , neural response telemetry , brainstem auditory evoked potential , and P300, among others.
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 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.
Patients who are genetically diagnosed with the recently reported and rare Wolfram syndrome type 2 ( WFS2) and have the degenerative and symptomatic disease including signs such as diabetes, platelet aggregation defect or visual problems will be asked to participate in this study. Knowing the pathomechanism of WFS2 with rapid cell death, after doing baseline investigations to asses the severity of their disease, the participants will be offered a chelator therapy with in addition to the antioxidant Acetylcystein, in diabetic patients an Incertin (GLP-1 ) therapy will be offered as well. The baseline investigations will be repeated after 2 months and after 5 months of therapy in order to asses the progression of the disease and to show if the chelator and anti oxidant therapy and in diabetic patients the GLP-1 therapy could stop the progression of the disease.
People with the congenital anatomical malformation known as "Enlarged Vestibular Aqueduct" (EVA) may experience decline in hearing ability. This is an online registry to gather patient experiences with EVA, with the goal of providing future researchers with the information necessary to better evaluate and make recommendations for patients with EVA. Data will be obtained from volunteers who enroll and submit their information on a website, https://eva.uhhospitals.org, and a limited data set may be provided to researchers interested in analyzing repository data. The limited data set would not contain any identifiable information except for ages, dates such as date of diagnosis, or city/state of residence.

This study investigates the possible benefits of using binaural spatialization techniques in digital wireless microphone systems for hearing aids. Speech intelligibility tests, speaker localization tests and preference tests are performed. The results of a diotic (current rendering) and a binaural (suggested rendering) rendering are compared.
The New Enrollment Post-Approval Study is designed to evaluate the safety and efficacy of the Esteem Totally Implantable Hearing System in subjects suffering from moderate to severe hearing loss.
Evaluate the Cochlearâ„¢ Nucleus® S-Round Window (S-RW) implant in newly implanted adults with broader requirements to be considered an eligible candidate.
Autologous human bone marrow mononuclear fraction (BMMF) will be harvested and given to children with bilateral moderate to severe sensorineural hearing loss. The aim is to determine if bone marrow mononuclear fraction (BMMF) infusion is safe, feasible, improves inner ear function, audition, and language development.
This study investigate weather one type of cochlear implant (CI) surgery (insertion of the electrode via paracentesis of the round window (RWA)) leads to less vertigo than another type of CI surgery (cochleostomy). The participants will be randomized into 2 groups: RWA or cochleostomy. They will be examined with a video head impulse test (vHIT) before and after CI surgery to clarify their vestibular function.
