View clinical trials related to Hearing Loss, Unilateral.
Filter by: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.
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).
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.
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 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).
Neck pain is a common complaint in the general population affecting 10-15% of the general population. females more than men. Known risk factors are: Trauma, Repetitive lifting of heavy objects at work, driving vibrating vehicles, frequents diving from boards and smoking. No study dealt with the possible role of unilateral loss of vision or hearing as a risk factor for the development of neck pain. Intuitively, one might suspect that unilateral blindness or deafness will lead to a tilted position of the head, in order to cover a better visual/audio field. This position, in time, might lead to the development of neck pain. Our hypothesis is that patients with unilateral blindness/deafness will suffer from neck pain more frequently than the general population.
The purpose of this 3-year prospective investigation is to examine the short-term and long-term (1 year)efficacy of the bone-anchored hearing aid (BAHA) in adults with single sided deafness
