Clinical Trials [694 Associated Clinical Trials listed on BioPortfolio]

Cochlear Implantation for Treatment of Single-sided Deafness

This is a research study to determine whether a cochlear implantation (CI) device can improve hearing in people who are deaf in one ear (known as single-sided deafness).

Evaluation of the Benefit of Antiviral Treatment With Valganciclovir on Congenital CMV Infection-related Deafness on Hearing and Balance

Congenital cytomegalovirus (CMV) infection is the leading cause of non-genetic neurosensory deafness and affects 0.5 to 1% of births. Twenty to thirty per cent of children will develop dea...

Cochlear Implantation in Pediatric Cases of Unilateral Hearing Loss

This feasibility study evaluates whether children with unilateral, moderate to profound sensorineural hearing loss experience an improvement in speech perception, hearing in noise, localiz...

Bilateral Cochlear Implantation in Children With the MED-EL Cochlear Implant

The purpose of this study is to evaluate and document longitudinal efficacy in young children implanted bilaterally with MED-EL COMBI 40+ / PULSARCI100/SONATATI100 cochlear implant systems...

Designing a Trial of Bilateral Cochlear Implantation in Adults

In the UK, cochlear implantation is the standard treatment for adults with 'severe-to-profound' deafness. This level of deafness means that without a cochlear implant they have difficulty ...

Effect of Cochlear Implantation on Quality of Life in Adults with Unilateral Hearing Loss.

Patients with moderate-to-profound sensorineural hearing loss in 1 ear and normal hearing in the contralateral ear, known as unilateral hearing loss (UHL) or single-sided deafness (SSD), may experienc...

Bimodal benefit for cochlear implant listeners with different grades of hearing loss in the opposite ear.

To determine speech perception in quiet and noise of adult cochlear implant listeners retaining a hearing aid contralaterally. Second, to investigate the influence of contralateral hearing thresholds ...

Cochlear Implantation in Children With Congenital Unilateral Deafness: A Case Series.

Cochlear implant is regarded as a treatment option for hearing rehabilitation of adults with unilateral sensorineural hearing loss. A clear benefit has been experienced in regard to speech comprehensi...

Using aided cortical assessment as an objective tool to evaluate cochlear implant fitting in users with single-sided deafness.

To assess the use of cortical auditory evoked potentials (CAEPs) to verify, and if necessary, optimize the cochlear implant (CI) fitting of adult CI users with postlingual single-sided deafness (SSD).

Results in Adult Cochlear Implant Recipients With Varied Asymmetric Hearing: A Prospective Longitudinal Study of Speech Recognition, Localization, and Participant Report.

Asymmetric hearing with severe to profound hearing loss (SPHL) in one ear and better hearing in the other requires increased listening effort and is detrimental for understanding speech in noise and s...

Medical and Biotech [MESH] Definitions

Hearing loss due to disease of the AUDITORY PATHWAYS (in the CENTRAL NERVOUS SYSTEM) which originate in the COCHLEAR NUCLEI of the PONS and then ascend bilaterally to the MIDBRAIN, the THALAMUS, and then the AUDITORY CORTEX in the TEMPORAL LOBE. Bilateral lesions of the auditory pathways are usually required to cause central hearing loss. Cortical deafness refers to loss of hearing due to bilateral auditory cortex lesions. Unilateral BRAIN STEM lesions involving the cochlear nuclei may result in unilateral hearing loss.

The cochlear part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The cochlear nerve fibers originate from neurons of the SPIRAL GANGLION and project peripherally to cochlear hair cells and centrally to the cochlear nuclei (COCHLEAR NUCLEUS) of the BRAIN STEM. They mediate the sense of hearing.

Surgical insertion of an electronic hearing device (COCHLEAR IMPLANTS) with electrodes to the COCHLEAR NERVE in the inner ear to create sound sensation in patients with residual nerve fibers.

Sensorineural hearing loss which develops suddenly over a period of hours or a few days. It varies in severity from mild to total deafness. Sudden deafness can be due to head trauma, vascular diseases, infections, or can appear without obvious cause or warning.

Multi-channel hearing devices typically used for patients who have tumors on the COCHLEAR NERVE and are unable to benefit from COCHLEAR IMPLANTS after tumor surgery that severs the cochlear nerve. The device electrically stimulates the nerves of cochlea nucleus in the BRAIN STEM rather than the inner ear as in cochlear implants.
