Active clinical trials for "Hearing Loss, Sensorineural"

A phase 2 trial with LY3056480 in patients with stable SNHL

The purpose of this clinical study is to validate the comparability of prescription formula fitting of hearing aids based on full diagnostic audiometry and SelfFit interactive fitting of hearing aids based on hearing loss screening (mild to moderate hearing losses) using in-situ audiometry, provided and executed through the mobile medical app.

This study studies the prevalence between obstructive sleep apnea syndrome and sensorineural hearing loss. We recruit patients who have been treated for sudden sensorineural hearing loss in Poitiers' University Hospital between 2010 et 2017, and we detect if they have OSA with a ventilatory polygraphy.

Stellate ganglion block (SGB) is known to increase blood flow to the innervation area of the stellate ganglion. Near infrared spectroscopy reflects changes of blood volume and allows continuous, non-invasive, and bedside monitoring of regional cerebral oxygen saturation (rSO2). Previous studies have shown the increment of the rSO2 on the block side from the baseline and the decrement of the rSO2 on the non-block side after SGB. Patients with cerebral vascular disease undergoing SGB might be at risk a decrease in cerebral blood flow in the non-block side. The investigators researched the effect of oxygen administration on rSO2 in the non-block side using a near infrared spectroscopy after SGB. 5 L/min oxygen was supplied via nasal cannula from 15 minutes after SGB. The rSO2 in the non-block side were measured before SGB and 5, 10, 15, 20, 25 and 30 minutes after SGB. The present study suggests that oxygen administration can increase the rSO2 of non-block side. In conclusion, it is our belief that oxygen supplement is helpful to the patient with cerebral vascular disease during SGB.

The objectives of the current project aim to determine whether a more controlled amplification method or a visual administration has an effect on hearing impaired older individuals' cognitive test scores.

This study will involve collaborating with oncologists in the post-chemotherapy follow-up appointments. The participants who wish to consent to this study will then answer 3 short questionnaires (THI, HHIA and SF-36) about hearing loss, tinnitus and quality of life. The audiologist or the researcher, under the supervision of an audiologist, will then perform a simple, non-invasive hearing test on the participant. Should the participant have a hearing loss, they will be advise to seek help from their General Practitioner.

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.

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.

The aim of this study is to investigate the effect of varying additional factors on loudness summation in Neuro Zti Cochlear Implant users.
