Filter by:This retrospective study is conducted to gain more knowledge on use and complications of 3mm long implants used in percutaneous (through the skin) bone-anchored hearing system (BAHS) surgeries in adults. Patients included have already been treated and recieved an implant with the wide diameter (Ø: 4.5 mm) design, either of 3- or 4mm length. The main purpose of the study is to investigate implant survival three months after implantation.
The goal of this clinical trial is to optimize hearing aid benefit based on the individual auditory-cognitive need using different hearing aid features in first-time hearing aid users between 45-80 years old with bilateral Phonak Audéo Paradise/Lumity 70 hearing aids. The main questions it aims to answer are: Does cognitive functioning affect hearing aid benefit? How can hearing aid fitting be optimized based on the individual auditory-cognitive profile? The hypothesis posits that cognitive abilities influence the effectiveness of hearing aids, alongside hearing status. Furthermore, if features of hearing aids improve speech understanding and listening effort, it is proposed that individuals with lower cognitive functioning will experience heightened benefits from hearing aids. The study will consist of three groups: one control group and two groups where one different feature will be modified. Participants will be tested at baseline measurement, including: - screening tests - audiological tests - questionnaires - cognitive tests - real-ear-measurement Following this, participants will be divided in one of the three groups, after which speech audiometry will be repeated. After a 4-week acclimatization period, the second measurement will take place, repeating speech audiometry and questionnaires. Subsequently, the hearing aid settings will be restored to their initial configuration.
The need for future hearing rehabilitation is enormous. World Health Organization (WHO 2021) has estimated that by 2050, 2.5 billion people will have some degree of hearing loss, and 1/4 of them will require hearing rehabilitation. Currently, healthcare systems and processes are already overwhelmed and not adequately equipped to screen and diagnose this rapidly growing population suffering from hearing impairment. This study aims to investigate if the diagnostics of age-related hearing loss can be accelerated by involving patients in the hearing assessment process.
Hearing loss is one of the most prevalent impairments in the world. The World Health Organization estimates that as of 2020, around 466 million people worldwide are affected by disabling hearing loss, of which 34 million are children. Without appropriate diagnosis and treatment, hearing impairment can cause difficulties with communication, learning, social-emotional functioning, employment and quality of life. Early intervention is especially important for children, for whom unaddressed hearing loss has been proven to affect speech and language development, educational attainments, and social skills. Through early detection and interventions many of these impacts can be mitigated, highlighting the importance of accurate hearing diagnostics. Evaluation of speech intelligibility is a fundamental component of hearing assessment and rehabilitation. The current gold standard in measuring speech intelligibility relies heavily on behavioural tests. While these tests are reliable and fast in healthy adults, it is challenging to assess speech intelligibility for patients who cannot communicate clearly, such as young children. For example, behavioral tests require active participation from the patient, such as raising their hand when a sound is heard, or repeating words and sentences. Objective measures, for instance using electro-encephalography (EEG), could overcome the current challenges in hearing assessment and do not require active participation from the patient. For example, in Flanders, all newborns are screened with an objective test where a few sensors on the head detect brainwaves in response to sounds. However, objective tests only use simple sound stimuli, such as tones or clicks, which cannot be used to measure important high-level hearing outcomes, such as speech understanding. In other words, current objective tests are used to check if a person can hear a word, but they can't indicate if the person can understand the word. An obvious missing link in audiological practice is a diagnostic test that can measure high-level hearing outcomes such as speech understanding in an objective way. For this reason, CORGEE was developed. CORGEE uses a novel method of "neural speech tracking" to objectively measure speech intelligibility using EEG. In the current study, the efficacy and the clinical validity of the CORGEE software will be evaluated in young children with a hearing impairment.
The Montreal Cognitive Assessment (MoCA) is a screening test for detecting cognitive impairment that assesses several cognitive domains (attention and concentration, arithmetic and orientation, memory, etc.). The instructions as well as some test items of the MoCA are presented auditory (spoken). Consequently, performance on the MoCA may be co-dependent on hearing. Therefore, to rule out the possible negative influence of hearing loss on performance on the MoCA, a MoCA for individuals with hearing loss was recently developed. More specifically, the original MoCA was modified by providing the instructions audiovisually (spoken with visual support) as well as by replacing hearing-dependent items. Since replacing items may affect sensitivity and specificity, the MoCA for persons with hearing loss should be revalidated.
Children's motor skills and physical performance increase with age due to the development of neuromuscular and cardiorespiratory systems. Sensory impairment seen in children with hearing loss can cause balance and coordination disorders, as well as decreased muscle strength and respiratory functions. Anatomically, core stabilization is provided by the diaphragm, abdominal, hip, pelvic floor, and gluteal muscles. Training for these muscles is intended to improve strength, endurance, and neuromuscular control. This training can help to improve the control of intra-abdominal pressure, intersegmental control of the spine, and muscular control of trunk movement. It also helps in strengthening the respiratory muscles, especially the main inspiratory muscle, the diaphragm. In this study, the effects of core stabilization training on children with hearing impairments' thoracic mobility, functional ability, and trunk muscle endurance will be examined.
The results of the previous study on auditory effort in young children with cochlear implants show that pupils respond to the presence or the absence of the perceived stimuli. The investigators hypothesize that the perceived sounds will elicit increased pupil dilation compared to the non-perceived sounds and that the hearing threshold as measured with pure tone audiometry will correlate to the results in pupillometry test. The investigators hypothesize that the effect will be visible in all testing groups albeit the relative increase of pupil size with age. Hypothesis confirmed, the investigators will develop a standardised procedure for the auditory signal detection using pupillometry. Such a procedure could represent an important bridge between automatic and behavioral hearing tests. With a more precise test of auditory threshold of young children, post-operative monitoring and fitting of cochlear implants or hearing aids, and rehabilitation procedures, could be considerably more targeted and consequentially more efficient.
Background: Many disorders of the head and neck can affect a person s hearing; balance; smell; taste; swallowing; voice; or speech. These disorders include cancers and genetic and inflammatory diseases. To find better ways to diagnose and treat these disorders, researchers need to study tissues and other biological samples from people who have them. Objective: To collect biological samples for a repository that will be used for research. Eligibility: People of any age with a disorder of the head and neck that requires the taking of biological samples. The conditions may be any that affect hearing; balance; smell; taste; swallowing; voice; or speech. Design: Part 1: Participants will give permission for their leftover tissue samples to be used for research. These are tissue samples from the head and neck that were collected in the course of routine tests and care or other research studies. Information on each participant s age, diagnosis, and previous treatments will also be collected. Part 2: Some participants may be asked for more samples. All those aged 3 years or older will have a physical exam. They will provide blood and saliva samples. A cotton swab or brush will be used to collect cells from the inside of the cheek. Participants 18 years or older may have additional tests. They may provide nasal secretions: A piece of gelfoam or a sponge will be placed in the nose to soak up secretions for 5 to 10 minutes. They may have biopsies: Small samples of tissue will be cut from the skin and the tissue lining the mouth. Samples may be used for genetic testing.
