Filter by:Single-sided deafness (SSD) refers to severe to profound sensorineural hearing loss on one side (average pure-tone hearing threshold≥70 dB HL at 0.5, 1, 2, and 4kHz) while the opposite side maintains normal hearing or mild hearing loss (30 dB HL). Asymmetrical hearing loss (AHL) refers to severe to profound sensorineural hearing loss in the bad ear (average pure-tone hearing threshold≥70 dB HL at 0.5, 1, 2, and 4kHz) and mild to moderate hearing loss in the contralateral ear. Moderate hearing loss (30≤mean pure-tone hearing threshold≤55dBHL). It is generally acknowledged that SSD is a particular clinical manifestation of AHL. The number of people who have hearing loss accounts for 5.3% of the total population, with children for 9%. According to the Second National Sampling Survey on Disabled Persons, China has 27.8 million people with hearing disabilities. The incidence of SSD adults in the United States is 7.2%, with 60,000 new cases per year, compared with 7,500 new patients with SSD annually in the UK. The incidence of SSD in neonates is 0.04%-0.34%, and it ranges from 0.1% to 0.5% in children and adolescents. The etiology of congenital SSD is primarily unknown, which is related to genes. Among the causes of acquired SSD, sudden deafness is the most common. Other causes include head trauma, Meniere's disease, labyrinthitis, unilateral acoustic neuroma, middle ear surgery, ototoxic drug exposure, Virus infection, noise-induced deafness, senile deafness, etc. SSD and AHL impede intellectual development and speech development in children and adolescents, which is associated with the side of hearing loss. For example, children with right-sided hearing loss have relatively poor language learning, logical thinking, and divergent thinking. In contrast, children with left-sided hearing loss have weaker analytical, comprehensive and visual memory abilities and relatively poor spatial imagination and visual-motor coordination. In addition, the lack of long-term monaural listening and sound source localization makes SSD children require excessive concentration, which is prone to fatigue and behavioral problems, and their academic performance is lower than that of normal children.
Among risk factors of neurodevelopmental disorder is congenital hearing loss. However, congenital deafness is neither necessary nor sufficient for the occurrence of warning signs of neurodevelopmental disorder. The investigative team hypothesizes that the co-occurrence of these two clinical entities results from a common origin, within a syndromic diagnosis including other medical issues. These situations would therefore be very different from those of babies suffering from isolated sensorineural deafness. This study aims to identify which factors are statistically correlated with the association of congenital deafness and early symptoms of neurodevelopmental disorder, thanks to a partnership between a regional center for psychiatry of deaf children (Therapeutic Childhood and Deafness Unit of St Maurice Hospitals, UTES) and a pediatric audiophonology department (ENT department of the Necker-Enfants Malades hospital). This work is based on a cohort of 26 children under ten months of age diagnosed with severe to profound congenital sensorineural hearing loss. As part of their pre-implantation cochlear assessment, a consultation was filmed to precisely analyze the interactional and sensorimotor skills of these children (clinical observations, administration of a specific evaluation grid called Olliac Grid), after reviewing the films. The investigative team will then be able to grade the neurodevelopmental risk. In order to clarify what factors are linked with a neurodevelopmental risk, medical data concerning the child's family context, birth, and audiological profile will also be collected, and put in perspective with the assessed neurodevelopmental risk gradation.
Participants will be recruited by performing chart reviews of patients to be seen at University of Texas Medical Branch at Galveston Ophthalmology and Optometry Clinic. A sample size of at least 30 patients is needed (60 eyes). Patients aged 55 and higher will be further evaluated to meet the inclusion criteria. Patients meeting inclusion criteria will be provided with informed consent to participate in the study before their office visit. Patients will receive a consent briefing then asked to sign and date the informed consent form. Participants will then be randomized to undergo an eye exam and refractive exam with noise cancelling Bluetooth headphones for one eye and without for the other eye. Participants will fill out a written survey asking them to rate the quality of the eye exam with and without headphones. Primary aim: Assess the quality improvement of Ophthalmic exam in geriatric patients with hearing loss with use of noise cancelling headphones with Bluetooth feature. Secondary aims: 1)Compare the response to the standardized questions with and without Bluetooth noise cancelling headphones to determine their effectiveness in conducting Ophthalmic refractive exam. 2) Explore the ease of conducting refractive exam as reported by provider.
The proposed study is designed to evaluate the effect of at-home executive function training on cognition and mobility in older adults with age-related hearing loss (ARHL), older adults with normal hearing, and middle-aged adults.
Vestibular loss can co-occur with hearing loss causing dual sensory deficits. This project examines vestibular loss as a contributing factor to reading difficulties for children with hearing loss, where previously only the effects of hearing loss and subsequent language difficulties have been considered. These results are expected to influence the identification and habilitation of vestibular loss in children with hearing loss.
The investigators balance and balance related problems and exercise programs should be handled multi-dimensionally. In this study, the investigators' aim is to investigate the effect of dual task-oriented education with stroboscopic glasses on balance, functional mobility and general walking parameters in children with hearing impairment, despite conventional balance exercises. The study will be started when the consent form which prepared in accordance with the ethical committee conditions, explained and approved to all participants and their families. Participants aged 7-12 years, who have not undergone cochlear implant surgery, who can walk independently, have a hearing threshold of 75 decibels (dB) and above, and are diagnosed with congenital bilateral sensorineural hearing impairment will be included in the study. Hearing impaired children who have physical, visual impairment, lack of cooperation for the application and have any neurological problems (other than sensorineural hearing loss) or orthopedic problems that may affect their balance will not be included. Children who meet the inclusion criteria will be divided into three groups by block randomization method; as control (Group 1), conventional exercise balance (Group 2), dual task-oriented stroboscopic visual training group (Group 3) and a healthy control group (Group 4) without any disability will form the fourth group. Only assessments and scales will be applied to the participants in Group 1 and Group 4 at the beginning of the study and at the end of 12 weeks. Group 2 and Group 3 will be included in the exercise program twice a week for 40 minutes for 12 weeks. Conventional balance exercises are planned to be done in groups, and other trainings are planned with one-on-one therapist. Before starting exercise training, demographic characteristics such as dB values (specified in the health reports of), age (years), height (cm), body weight (kg) of the children included in the study will be recorded. At the beginning of the exercise training and at the end of the 12-week training; balance, functional mobility and gait, fall history and fear of falling, quality of life, hand-eye coordination will be evaluated. This study is important in terms of being an example for researches to be carried out for the hearing impaired or other disability groups and contributing to the exercise programs of the trainers working in this field.
Migraine and sudden sensorineural hearing loss(SSNHL) are two related disorders. A systemic steroid is usually used to treat SSNHL but the role of migraine prophylaxis medication remained unknown. Mehdi Abouzari et al. found a better improvement when combining topiramate and nortriptyline with steroids in a retrospective study. However, a prospective study with randomization is needed to elucidate the efficacy of these agents. This is a clinical study using medication approved and currently prescribed in the clinic. The included patients were those who came to the clinic and were diagnosed with SSNHL within 14 days of onset. Those patients were asked whether they agreed to participate in this clinical trial. Patients who were diagnosed with SSNHL but were later found to be other diseases such as Meniere's disease and cerebellopontine angle will be excluded from this study. The involved patients were randomized divided into two groups. Both groups received systemic steroids with/without intratympanic steroids. The experimental group receives additional oral topiramate for 6 weeks. Follow-up time is at least 3 months. This study is multi-center. Location of the study is performed at Chang gung memorial hospital Linkou branch, Taipei branch, Taoyuan branch, and New Taipei Municipal Tucheng Hospital.
Cochlear fibrosis development can compromise the success and the outcomes of the cochlear implantation (CI) thus affecting the quality of life of the implanted patient. Correlating the results of the Transimpedance Matrix (TIM) measurements to the implant electrode location determined by the Cone Beam Computer Tomography (CBCT), this study aims to identify a range of TIM profiles within the implanted population, certain profiles suggesting the growth of the fibrosis tissue in cochlea
The purpose of this study is to follow the natural history of non-syndromic hearing loss caused by mutations in two genes (GJB2 or OTOF) in children up to 10 years of age.
Using a randomized controlled trial, we are going to examine whether a training program that incorporates both auditory training and working memory training (AT-WMT) would generate significantly better results in communication and cognition than an auditory training program and a mindfulness training program (active-control). Participants are 120 older adults (40 per group) with untreated mild-to-moderate sensorineural hearing impairment .
