Natural History in Children up to 16 Years With Mild to Profound Hearing Loss Due to Mutations in GJB2 / OTOF Genes

The purpose of this study is to follow the natural history of non-syndromic hearing loss caused by mutations in two genes (GJB2 or OTOF) in children up to 16 years of age.

Pivotal Clinical Trial Evaluating the Safety and Efficacy of the Fully Implanted Acclaim Cochlear Implant

The goal of this clinical trial is to learn if the Acclaim CI works to treat severe to profound sensorineural hearing loss in adults. It was also learn about the safety of the Acclaim CI implant. The main questions it aims to answer are: * Does the Acclaim CI device help participants hear words better compared to before the implants? * What medical problems do participants have after the Acclaim CI device was implanted? Participants will: * Have the Acclaim CI implanted; and * Visit the clinical site for checkups and tests at 1-Month, 3-Months, 6-Months, and at 1-year and 2-years after the device has been turned on.

Gene Therapy Trial for Otoferlin Gene-mediated Hearing Loss

Part A of this trial will evaluate the safety and tolerability of a single surgical administration procedure in one or both ear(s) with one of two dose levels of AAVAnc80-hOTOF and will evaluate the Akouos Delivery Device, together with the Precision Delivery Mechanism, to safely achieve the intended product performance.

Otoferlin Gene-mediated Hearing Loss Natural History Study

This is a retrospective and prospective longitudinal study in participants with Otoferlin Gene-Mediated Hearing Loss.

Comparison in New Cochlear Implanted Subjects of a Tonotopy-based Bimodal Fitting and a Conventional Fitting

Main objective: For a bimodal fitting (hearing aid (HA) + cochlear implant (CI)): Comparison of a tonotopy based fitting strategy (TFS4) to a default fitting strategy (FS4) for the speech recognition in noise. Secondary objectives: Comparison of TFS4 to FS4 for speech recognition in quiet. Comparison of TFS4 to FS4 for the auditory skills experienced by the subject.

Comparison in New Cochlear Implanted Subjects of a Tonotopy-based Bimodal Fitting With or Without Synchronization

Main objective: For a bimodal fitting (hearing aid (HA) + cochlear implant (CI)): Comparison of a tonotopy based fitting strategy with synchronization between HA and CI (ABFS) to a tonotopy based fitting strategy without synchronization (ABFnoS) for the accuracy of sound localization. Secondary objectives: Comparison of ABFS to ABFnoS for the bias of sound localization. Comparison of ABFS to ABFnoS for speech perception in noise. Comparison of ABFS to ABFnoS for the auditory skills experienced by the subject.

Auditory Performances With Different Stimulation Depths in Cochlear Implanted Subjects Using a Fine Structure Strategy

Main objective: Investigate on new cochlear implanted patients whether the FineHearing strategy of the MED-EL cochlear implant gives better results on musical perception if the depth of stimulation (stimulation or not of the apical areas) is greater. Secondary objectives: Evaluate the effect of stimulation depth on vocal audiometric results, results of differential frequency threshold test and on qualitative sound perception.

Cross-sectional and Prospective Study to Characterize Early-onset Presbycusis

The purpose of this study is to characterize and assess the evolution of hearing impairment of patients with adulthood-onset bilateral sensorineural hearing loss carrying mutations on GJB2 gene.

Speech Perception of a Tonotopy-based Fitting for Cochlear Implant Recipients for 6 Months With Conventional Setting

Main objective: Compare speech recognition in noise with tonotopic fitting (FS4T) and with conventional non-tonotopic fitting (FS4noT) in adult patients implanted for 6 months with a MED-EL cochlear implant with FS4noT strategy. Secondary objectives: Comparison of FS4noT and FS4T settings * for speech recognition in quiet * for subjective auditory spatial perception

Comparison of Speech Understanding Between Tonotopy-based Fitting and Setting Based on Evolutionary Algorithms

Main objective: Compare speech recognition in noise with tonotopic setting (FS4T) and with tonotopic fitting modified by evolutionary algorithm (EAFS4T) in adult patients implanted for 6 months or more with a MED-EL cochlear implant with FS4T. Secondary objectives: Comparison of FS4T and EAFS4T settings * for speech recognition in quiet * for subjective auditory spatial perception * for subjective auditory and musical perception

Post Approval Study to Assure the ContInued saFety and effectIveness of Neuro Cochlear Implant System in Adult Users

On June 23, 2021, the Oticon Medical Neuro Cochlear Implant System (NCIS) was granted premarket approval (PMA) in the US to treat individuals 18 years or older, with bilateral severe-to-profound sensorineural hearing loss, who obtain limited benefit from appropriately fitted hearing aid(s). To help assure the continued safety and effectiveness of an approved device, a post-approval study was required as a condition of approval under 21 CFR 814.82(a)(2). The purpose of this study is to provide longer-term data on the safety and effectiveness of the Neuro Cochlear Implant System under general conditions of use in the postmarket environment.
