Active clinical trials for "Hearing Loss"

A bone-anchored hearing aid (Baha) consists of a titanium implant located at the mastoid, and a sound processor connected with the implant. The sound processor delivers bone conducted stimuli to the cochlea, bypassing the outer and middle ear. Some patients who are unable to wear or do not benefit from a conventional air-conduction hearing aid, are candidate for a Baha. Typically, these patients suffer from a conductive or a mixed hearing loss. Recently however, Baha's are also being recommended in patients with unilateral deafness. Sound coming from the deaf side is captured and transmitted through bone conduction to the normal inner ear. The overall benefit of a Baha is more difficult to assess in those patients. Therefore, the goal of the current study is to examine the benefit of a Baha in patients with different audiological profiles (unilateral or bilateral conductive or mixed hearing loss, and unilateral deafness). Special attention will be given to predictive determinants of the benefit with a Baha, and to the improvement of pre-operative criteria and counseling of patients.

The main objective of this study is to evaluate the correspondence between eCochG and residual hearing by adding two modifications. First, a novel technique for placing and maintaining the probe in place during the whole insertion will be used. Second, a new metric for estimating the eCochG response will be evaluated (eCochG trauma index). The secondary objective is to find other markers of the cochlear trauma insertion associated to eCochG measures. This will be used to evaluate to which extend a traumatic insertion will be deleterious for the patient's post-operative hearing, and ultimately to prevent trauma to the inner ear. Finally, the potential differences in cochlear trauma resulting of the electrode array insertion from two different surgery techniques will be investigated; Either using a manual insertion or using a robotic arm that will drive the insertion automatically.

The primary objective of this study is to obtain a greater understanding of the range in benefit from acoustic amplification combined with electric stimulation in cochlear implant recipients with low-frequency hearing who do not currently use the commercially approved Advanced Bionics Acoustic Earhook. The aims of this study are to 1) obtain subjective sound quality judgements of recorded speech and music samples, 2) assess vocal emotion perception, and 3) evaluate post-operative speech perception and sound field detection thresholds in CI recipients both with and without use of the acoustic ear hook.

In France the indication of bilateral cochlear implant (CI) is limited to specific cases. The impact on perception and language of bilateral CI simultaneous versus sequential has to be established before discussing the enlargement of indications.

This is an observational study to examine the characteristics of gene-related hearing loss in pediatric participants with biallelic otoferlin (OTOF) Mutations, Gap Junction Beta 2 (GJB2) Mutations, or Digenic GJB2/Gap Junction Beta 6 (GJB6) Mutations. This study will follow the participant for 4 years with annual visits each year.

The primary objective to this study is to describe the auditory development and performance of young deaf children who receive bilateral implants during the first two years following device activation.

The purpose of this proposed study is to examine the benefits of using electropalatography (EPG) during speech therapy with adult individuals who are either congenitally deaf or adventitiously deaf and use a cochlear implant.

Hearing loss maybe: -Symmetrical: in which the severity and pattern of hearing loss are the same in each ear. Or -Asymmetrical: is defined as binaural difference in bone conduction thresholds of >10 dB at two consecutive frequencies or >20 dB at one frequency (0.25-8.0 kHz), Poorer speech perception will often accompany poorer hearing and may be the reason for the patient's presentation .Unilateral or asymmetrical sensorineural hearing loss is important to discern, as it is an important risk factor for auditory nerve tumors (i.e. vestibular schwannoma) which is a life threatening condition, and in such cases further investigation is required (i.e. MRI scan) unless there is a known reason for the asymmetry, Several reports have recommended that further evaluation, especially expensive imaging studies, be conducted to rule out acoustic tumors when AHL is present

At present, few research on the auditory perception function and possible neural mechanisms of unilateral sudden hearing loss patients with complete or partial recovery of peripheral hearing.This project evaluate the speech perception function in noise of unilateral sudden hearing loss patients with with complete and partial hearing recovery by cognitive behavioral experiments, event-related potentials (ERPs) and functional magnetic resonance imaging (fMRI), and longitudinal follow-up to explore its underlying neural mechanisms.

Vestibular system activity supports many functions ranging from gaze stabilization and postural control to high-level cortical functions involving spatial cognition, body perception, verticality perception, orientation, navigation, and spatial memory. Few studies have assessed the impact of a vestibular deficit on executive functions taking into account the simultaneous existence of sensorineural deafness in a child population. The BRIEF questionnaire (Behavioral Rating Inventory of Executive Function) allows a parental assessment of executive functions and is validated from the age of 5. Children were recruited from a pediatric population followed in the Ear Nose and Throat (ENT) department for audio-vestibular assessment and BRIEF questionnaire was completed by the accompanying parent.
