Filter by:The goal of this observational study is to describe the multi-omics characteristics and to learn about the prognostic factors in patients with idiopathic sudden sensorineural hearing loss (SSNHL). The main problems it aims to deal with are: - if there is a difference in data of exome and targeted sequencing among patients with SSNHL affecting bilateral and unilateral sides, and healthy controls - if there is a difference in the parameter of MRI among patients with SSNHL affecting bilateral and unilateral sides, and healthy controls - to find out which factor from multi-omics data relates to outcomes of SSNHL - to develop the best prognostics model based on the multi-omics data. Participants will be received audiological tests, blood specimen collection and radiological examination. Researchers will explore the relationship between the multi-omics data and the prognosis and develop the predictive model.
The goal of this clinical trial is to investigate the factors and mechanisms underlying tinnitus generation and chronification in patients with sudden sensorineural hearing loss (SSNHL) . The main questions it aims to answer are: - What are the peripheral and central influencing factors that contribute to tinnitus in patients with SSNHL? - Can serum metabolic biomarkers be identified to predict and monitor tinnitus prognosis in these patients? Participants in this study will include patients with SSNHL and tinnitus, patients with SSNHL without tinnitus, and healthy subjects. They will be asked to undergo a series of assessments, including audiological tests, vestibular function examinations, and functional magnetic resonance imaging (fMRI). Additionally, blood samples will be collected for metabolomics analysis. Investigators will compare the brain functional states and serum metabolite profiles of patients with SSNHL and tinnitus to those without tinnitus. Morever, tinnitus symptom characteristics, audiological outcomes, and brain functional states will be assessed during time.
The purpose of this study is to characterize and assess the evolution of hearing impairment of patients with adulthood-onset bilateral sensorineural hearing loss carrying mutations on GJB2 gene.
The objective of this study is to examine whether ABO and Rhesus (Rh) blood group systems have an association with distortion product otoacoustic emission (DPOAE) and transient otoacoustic emission (TEOAE) amplitudes with the hypothesis of blood groups may affect hearing thresholds.
Cochlear implants (CIs) are devices that partially restore hearing for people with severe to profound hearing loss. This research focuses on CI users who use bilaterally implanted devices (two CIs, one on each side) and also "single-sided deafness" (SSD) CI users who use one CI together with good acoustic hearing in their opposite ear. The goal is to measure and understand the impact of large input asymmetries across the two ears. These asymmetries are common in BI-CI listeners and always present in SSD-CI users. Although most CI listeners benefit from a second source of auditory input, this project measures how these asymmetries limit speech understanding and spatial hearing. The long-term goal is countering or compensating for input asymmetries. Electrophysiological measures are used to describe the health of the auditory system. Behavioral measures are used to assess if training improves performance. CT imaging is utilized to describe the placement of the CIs.
This is a retrospective study designed to collect speech perception results for HiRes Ultra CI and HiRes Ultra 3D CI users as measured in the clinical routine and to confirm the performance of these devices.
This is a retrospective study designed to collect long-term speech perception results for cochlear implants recipients using electro-acoustic-stimulation as measured in the clinical routine and to confirm the performance of sound processors associated with acoustic earhooks.
This study aims to investigate the effect of stimulation parameters and different electrode modes on speech perception in adult cochlear implant recipients.
This study aims to evaluate the safety and efficacy of cochlear implantation for adults with bilateral sensorineural hearing loss who currently do not meet the FDA-approved indications for cochlear implantation. Following cochlear implantation, participants will complete speech perception assessments and questionnaires over the course of seven visits.
Evaluation of the diagnostic and prognostic efficacy of nuclear magnetic resonance imaging in patients with acute sensorineural hearing loss or in patients suffering from probable or definite MD. The neuroradiological and audiological evaluation are held on in the same day in order to better clarify the radiological and clinical correlates.
