Filter by:Hearing is the ability to perceive sounds through the ear. If the transmission of sound is defective, the person suffers some degree of hearing loss. Cochlear Implants (CI) provide partial hearing by stimulating auditory nerve cells. The evaluation of the functionality of the CI is facilitated by several analysis tools, such as the clinical calibration software. This offers the possibility of measuring electrical impedances in the cochlea. The electrical impedance is the opposition to the current flow between two electrodes. It is composed of two main elements: resistance and reactance. The impedances in a cochlear implant are not stable over time. The value is minimal immediately after surgery, and increases progressively in the first 2 to 3 weeks after the procedure due to the immune response of the organism against a foreign body and the trauma of the array insertion. Several authors have suggested the use of topical or intravenous corticosteroids to decrease intracochlear fibrosis. The use of Dexamethasone could have a protective effect by reducing the initial inflammatory response, apoptosis, and delayed fibrosis, which could impact the impedance. There is limited evidence on the effect of intra-surgical topical corticosteroids on the impedance of the cochlear implant. The aim of this clinical trial is to evaluate the impact of topical dexamethasone on the electrical impedance of the cochlear implant, with special attention to the analysis of the capacitive component. It will be carried out through an experimental, prospective, randomized and double-blind study. Objective To determine whether the use of topical dexamethasone in a single dose applied in the tympanic cavity (middle ear) during cochlear implant surgery modifies the capacitive component of the electrical impedance of the electrodes in the cochlea before the activation of the cochlear implant. Material and methods A phase 3 clinical trial will be conducted. The design is a parallel, randomized, controlled and double-blind experimental study. Expected impact The use of local dexamethasone during cochlear implant surgery would decrease the inflammatory response, improving postoperative impedances.
A hearing loss affects the quality of life and the natural development of children. The new generation of hearing devices provides a huge number of options to them. These new hearing aids are often aesthetically acceptable, less invasive and user-friendly. The ADHEAR Non-Implantable Bone Conduction Hearing System is connected directly to the skin with a special adhesive adapter. The device transmits the sound to the mastoid by vibrating on the skull and stimulates the inner ear without any previous surgery. The objective of this study is to evaluate of the audiological benefit and subjective satisfaction of ADHEAR Audio Processor with Adhesive attachment in a group of children suffering from conductive hearing loss and/or single sided deafness.
As part of the proposed work, the investigators would like to examine whether there is a need to use a training video to train IDF combat soldiers to improve the use of ear plugs and to prevent hearing loss from exposure to noise, and to characterize the hearing impaired epidemiology of recruits and the basic rate of hearing loss During basic training.
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.
The present cross-sectional study aims to examine the cognitive capabilities of older adults, aged 50 to 89, with normal hearing or age-related hearing loss by means of the Repeatable Battery for the Assessment of Neuropsychological Status for Hearing impaired individuals (RBANS-H). Secondly, the correlations between cognition on the one hand and hearing and speech reception capabilities on the other hand are investigated. For this purpose, twenty participants are included in the age categories 50 to 59, 60 to 69, 70 to 79 and 80 to 89, bringing the total number to 80. Three questionnaires are administered to the participants: the Health Utilities Index-2/3 (HUI 2/3), Dizziness Handicap Inventory (DHI) and a general questionnaire on education and profession, medical history, hearing aid use and tinnitus. Also an audiological examination is performed, including pure tone audiometry, speech in quiet and speech in noise audiometry. Finally, cognition is assessed using the RBANS-H.
This study evaluates the efficacy of using augmentative and alternative communication (AAC) technology for enhancing language development in children who are deaf or hard of hearing. Half of the participants will receive AAC technology with their speech and language therapy and half will continue with their usual care models.
The purpose of study is to determine the diagnostic value of Hearing test program on smart phone for detected patients who has hearing loss.
This study is an open label proof of concept study of rilonacept for patients with ANSHL
The cognitive profile of older adults with a severe to profound hearing impairment is determined by means of the Repeatable Battery for the Assessment of Neuropsychological Status, adjusted for Hearing impaired subjects (RBANS-H) before and after cochlear implantation. In this prospective, longitudinal study the participants are tested preoperatively, at six months and twelve months postoperatively and from then on yearly up to 10 years after implantation. In addition to the RBANS-H an audiological examination and an semistructured interview is conducted concerning the cochlear implant use and the self-reliance of the patient and subjective questionnaires are filled out by the subjects to assess quality of life and hearing benefit.
This community-based cross-sectional survey will estimate the frequency and risk factors of Chronic Suppurative Otitis Media and Hearing Impairment in Children ages 4-6 years in the Chikwawa District. These data will be useful for service planning, disease prevention efforts and to guide future research in this field.
