Active clinical trials for "Hearing Loss, Sensorineural"

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 understanding what people are saying even when they wear hearing aids. The NHS provides a cochlear implant for one ear even though these adults are deaf in both ears. Two cochlear implants could help them understand speech in noisy environments, know where to look to see who is talking, and avoid hazards outdoors. The decision about who can receive cochlear implants and how many they can receive is based on guidance from the National Institute for Health and Care Excellence (NICE). NICE agreed that providing two cochlear implants can provide additional benefits over providing just one implant. However, they decided that there is not enough evidence to show that these additional benefits are worth the additional cost of providing the second implant. NICE recommended that a clinical trial should be conducted to gather this evidence. This study will consult with patients to explore whether the trial would be acceptable to future implant recipients. The study will also work with clinicians to design a trial comparing bilateral and unilateral implantation in adults. These clinicians will also be surveyed to assess the acceptability of the trial. A group of clinicians that span the range of professions involved in delivering the care pathway will be invited to attend a trial design workshop to establish a consensus on acceptable trial design elements from a clinical perspective. Representatives from cochlear implant manufacturers will be consulted to determine possible strategies for securing industry support for a future trial. Those who run cochlear implantation services will be engaged in a working group to gather information on the current care pathway to inform future assessments of whether bilateral implantation could be cost-effective.

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.

The aim of this study is to evaluate hearing characteristics in patients with and without tinnitus using DPOAE and specific tinnitus severity index (TSI) and tinnitus handicap inventory (THI) questionnaires in both groups. Purpose of the research: Demonstrate that the characteristics of tinnitus depend on the presence and magnitude of hearing loss. Research participants: 150 patients coming for further audiological treatment due to tinnitus. Data will be collected from an electronic database that is filled in during diagnostic processing. During the diagnostic processing, TSI and THI questionnaires will be filled in, a tone audiogram (TA) and DPOAE will be performed.

Study on patients with CNS infections.

The function of the vestibular system among patients with Sudden Sensori Neural Hearing Loss will be evaluted using the video Head Impulse Test

Evaluation of the outcome of cochlear implantation (CI) is very important issue since adequate hearing is linked to improved communication outcomes and school performance, development of speech and language, enhances speech perception in quiet and noise and even allows CI recipients to use the telephone. As well as there is a growing need for a widely used set of international quality standards on minimal outcome measurements to determine outcomes in CI recipients, monitor the auditory progress of CI recipients over time and to be able to relate on important issues as the most ideal age for implantation and the cut-off audiological thresholds for CI indication. This study will be conducted to evaluate outcome of cochlear implantation in sohag university hospital. Aim of work: To evaluate the outcome of cochlear implantation in Sohag university hospital.

Determining acceptability and usability of a wearable open-source speech processing platform (Master Hearing Aid) developed for hearing-aid research

To explore the genotype-phenotype correlation of SLC26A4 mutations in cochlear-implanted patients with enlarged vestibular aqueduct.

The purpose of this study is to measure the size of the round window niche and its relation to the mastoid segment of the facial nerve and the mastoid cortex, using high resolution computerized tomography of the temporal bone, in order to assess preoperatively what is the extent of obstruction of the round window membrane and whether there is a surgical possibility of round window approach in the insertion of electrode array into the cochlea
