View clinical trials related to Unilateral Hearing Loss.
Filter by:Patients with unilateral transmission hypoacusis due to otosclerosis undergoing stapedectomy surgery will be prospectively included. They will be undergoing a free field vocal audiometry using the Oldenburg MATRIX software to evaluated the squelch effect gain between audiometry before and after 9months after surgery. Our hypothesis is to show a squelch effect with the rehabilitation of the binaural audition.
The objective is to study the relation between the reorganization of the central auditory system, and the psychophysical deficits in binaural hearing in subjects with single sided deafness.
Unilateral hearing loss (UHL) in children has been demonstrated to have a negative impact on quality of life, school performance and behavior. Despite this knowledge, it remains unclear how to best manage this common problem. There has been much debate regarding this issue with many programs recommending preferential seating in the classroom and use of a frequency-modulated (FM) system to amplify the teacher's voice in the classroom (conventional measures), and others recommending these accommodations in addition to use of a hearing aid for amplification (amplification). There is very limited research to support or refute the efficacy of a hearing aid in improving measurable academic, behavioral, or quality-of-life (QOL) outcomes in children with UHL. We propose a study evaluating the impact of hearing aid use in school-aged children (ages 6-12 years) with mild to moderately severe UHL. In this study, subjects will be randomized to receive either conventional measures or conventional measures plus amplification. After a three month period, the groups will be reversed, with each subject serving as their own control. Outcome measurements will include patient reported disease-specific QOL reported by patients, parents, and teachers using validated survey instruments at regular intervals throughout the study period.
People with single-sided deafness (SSD) have significant hearing loss in one ear and normal or near normal hearing in the other ear. Those living with SSD experience several communication difficulties, particularly when listening to speech in the presence of background noise. This problem is worse in situations where the noise is on the side of the good ear and the speech is on the side of the poor ear. The Bone-Anchored Hearing Aid (BAHA) and the Contralateral Routing of Signals (CROS) hearing aid are two devices designed to improve hearing in people who have significant hearing loss in one ear only. The BAHA is a surgically implanted device which also includes an external processor; sounds from the poor ear are transmitted to the good ear through skull vibrations. The CROS does not involve surgery; instead a hearing aid is fitted behind each ear, and the sounds on the side of the poor ear are wirelessly transmitted to the good ear. The majority of previous studies comparing the BAHA to the CROS have used older CROS models with basic technology and a wire along the neck to send sounds from the poor ear to the good ear. There is a lack of studies comparing newer digital wireless CROS hearing aids to the BAHA. The current research will compare the effect of the BAHA and CROS hearing aid on speech perception scores when listening to speech in quiet and in noise. The research will also investigate patients' reported benefits with each device during everyday situations. In order to compare the BAHA and CROS, individuals who already have been implanted with a BAHA will be given a trial period with a new wireless digital CROS hearing aid. The research hypothesis states that the CROS hearing aid will be as equally beneficial or greater than the BAHA in improving hearing and patient benefit. If the findings support the hypothesis that the CROS offers just as much benefits as the BAHA, or is an even better alternative, more patients may choose to avoid surgery and decide to receive a CROS hearing aid instead.
The objective of this study is to assess the long-term safety and quality of life improvement of the Sonitus SoundBite Hearing System.
The purpose of this study is to determine the safety and efficacy of using bone conduction via the teeth to treat Single-Sided Deafness (SSD).
