Filter by:Background: People with hearing, balance, and taste, smell, voice, speech, language, and other Ear, Nose, and Throat (ENT) disorders may seek treatment at the National Institute on Deafness and Other Communication Disorders (NIDCD). Some of these people may benefit from enrolling in the NIDCD intramural research program to receive their care. Enrolling will also allow investigators to collect participants clinical data and specimens for future research. Objective: This natural history study has 2 goals: (1) to collect data and specimens that may be used for research; and (2) to evaluate participants who may be candidates for other research studies. Eligibility: People aged 2 years or older with a hearing, balance, and communication disorder. Those at risk or who are suspected of having such a disorder are also eligible. Design: Participants will be screened. Their medical records will be reviewed. Participants will agree to have their medical data used for research. Specimens such as blood or other tissue samples may also be used for research. All data and specimens will be collected during their routine care visits. All tests done will be the normal care for each participant s condition. No tests will be done solely for research. Some of these tests may require blood or tissue samples. Some may use special tools to test hearing and balance. Some may test heart or lung function. These tests may also include different types of imaging scans. All tests will be explained. Participants may ask questions at any time. Participants may remain in this study for up to 2 years. If they need further care, they may sign a new consent. ...
Many patients receiving cochlear implant (CI) have some residual hearing prior to implantation surgery. However, approximately one third of them will lose it in next 6 months after cochlear implantation. Although the mechanisms involved in the residual audition loss remain unknown, animal experiments suggest the role of inflammatory or immune reaction in the cochlea. The goal of this project is to search in the perilymph (a fluid which fills the scala vestibuli and scala tympani of the cochlea) some predictive biomarkers of the residual hearing loss using modern proteomics and immunological techniques. A parallel search for blood biomarkers of post-implantation residual hearing loss and for molecular and cellular evidences of immune response to cochlear implantation will be performed. The study will recruit 50 subjects-candidates for cochlear implantation surgery; 30 normally hearing individuals eligible for other types of otological interventions will form a control group. For all the participants blood samples will be collected and preserved. In addition, the perilymph sampling will be performed during cochlear implantation surgery. This project relies on the calculation that from 50 patients post-cochlear implantation, 15 patients will form a group with maintained residual hearing and 15 will display delayed hearing loss. For these 30 subjects together with the control group the blood biomarkers search will be performed. For the group of implanted patients, the follow-up will last for 12 months with 6 visits in total : - the inclusion visit V0 during which the study will be presented and the consent form will be signed - the surgery visit V1 with blood sample and perilymph collection - the activation visit V2, 1 month ± 1 week after V1, visit V3 3 months ± 7 days after V1, V4 6 months ± 7 days after V1, V5 12 months ± 1 month after V1. During each of this visit blood sampling will be performed. For the control group, the follow up will be 6 months long with 4 visits in total arranged during the routine follow-up appointments: - the inclusion visit V0 during which the study will be presented and the consent form will be signed - the surgery visit V1, the 1 month visit V2 and the 6 months visit V3 during which the blood sampling will be performed.
This Registry represents a non-interventional systematic collection of clinical data in which prospective data from children and adults are collected as fully anonymized data sets, derived from original clinical records on appropriately informed subjects. This is a patient-outcomes Registry for subjects of any age who are provided in routine clinical practice with one or more MED-EL hearing devices. The Registry aims to collect data for hypothesis generation on subject device use, auditory performance, quality of life and health-related utilities, across different types of implantable and non-implantable hearing devices from MED-EL company. Subjects will be evaluated with a set of standardized tests and questionnaires prior to implantation or prior to initial device activation (baseline) and at follow-up intervals according to the clinical practice.
Vestibular system activity supports many functions ranging from gaze stabilization and postural control to high-level cortical functions involving spatial cognition, body perception, verticality perception, orientation, navigation, and spatial memory. Few studies have assessed the impact of a vestibular deficit on executive functions taking into account the simultaneous existence of sensorineural deafness in a child population. The BRIEF questionnaire (Behavioral Rating Inventory of Executive Function) allows a parental assessment of executive functions and is validated from the age of 5. Children were recruited from a pediatric population followed in the Ear Nose and Throat (ENT) department for audio-vestibular assessment and BRIEF questionnaire was completed by the accompanying parent.
This single-blind, placebo-controlled trial will be conducted to evaluate the safety of FX-345 administered as a single intratympanic injection in adults with acquired sensorineural hearing loss. The primary objectives are to assess the local safety, systemic safety, and pharmacokinetic (PK) profile to determine systemic exposure.
Acute cochleo-vestibular syndrome or labyrinthitis is characterized clinically by the sudden appearance of a great rotatory vertigo and a unilateral sensorineural hearing loss. In this clinical context, MRI is the examination to eliminate differential diagnoses and to make a positive diagnosis of labyrinthitis (supposedly infectious, immunologic or ischemic). The etiologies described are ischemic, infectious or autoimmune, so the risk factors are very variable (cardiovascular, autoimmune or infectious). Labyrinthitis has been little studied as a clinical entity in its own right. Indeed, studies mainly focus on sudden deafness with subgroups of patients with vertigo. The incidence of sudden deafness is of the order of 5 to 20 per 100,000 people per year but is probably under-diagnosed. The individual and medico-economic consequences are similar to those of hearing loss, with an increased risk of dementia, depression, premature death and an increase in health care consumption.
The investigation proposes to compare a narrow reference beamformer to a novel beamformer approach, when the talker is not in front of the hearing aid user and in the presence of background noise. The beamformer effect will be determined in terms of speech intelligibility, listening effort and ability to multitask when the talkers are located on the side or in the back.
The goal of this project is to compare aided and unaided speech discrimination among infants with hearing loss and a cohort of infants with typical hearing. Working Hypothesis: Among this group of infants with hearing loss, performance will be significantly better when infants are tested while using amplification (i.e., aided condition) compared to when tested without amplification (i.e., unaided condition). Infants fit with optimally programmed amplification will perform similarly to the infants with typical hearing on speech discrimination tasks.
Interest and demand for sound amplifiers are increasing due to the burden of purchasing hearing aids and technological advances in healthcare products, and the demand is expected to increase rapidly. For sensorineural hearing loss patients, who are subject to wearing hearing aids, it aims to compare the effect of hearing aid application and personal sound amplification product (PSAPs) compared to the hearing aids
The purpose of this early feasibility study is to explore several facets of hearing performance that may show improvements for alternative modes of stimulation compared to Monopolar (MP stimulation) in cochlear implant recipients. This study will iteratively evaluate different parameter sets that intend to maximize hearing performance benefits within technical requirements. This study is exploratory in nature and will achieve its objectives through ongoing review and adjustment of device parameters and fitting
