Filter by:The purpose of this study is to measure the size of the round window niche and its relation to the mastoid segment of the facial nerve and the mastoid cortex, using high resolution computerized tomography of the temporal bone, in order to assess preoperatively what is the extent of obstruction of the round window membrane and whether there is a surgical possibility of round window approach in the insertion of electrode array into the cochlea
The purpose of this study is to determine the true incidence of long QT (LQT) amongst a large cohort of subjects diagnosed with unilateral (right/left) or bilateral sensorineural hearing loss.
Purpose: The purpose of this study is 1) to evaluate the safety and efficacy of currently available multichannel cochlear implant systems for newly implanted adults with an indication based on open-set sentence recognition that expand criteria currently used by Center for Medicare & Medicaid Services (CMS), and 2) to assess the correlation between measures of speech recognition in candidates for cochlear implants and their utility in predicting audiologic and quality of life outcomes after implantation. Participants: Adults (≥ 65 years of age) and CMS-eligible as a primary source of medical insurance coverage. Procedures (methods): Evaluate objective and subjective outcomes of cochlear implantation in a patient population that does not meet current CMS candidacy criteria.
To determine if autologous human umbilical cord blood infusion in children with acquired hearing loss is safe, feasible, improves inner ear function, audition and language development.
The accurate assessment of auditory status is critical for planning treatment for Veterans with hearing loss to include medical and audiological management. Current physiologic tests of auditory function in the standard clinical audiological test battery for Veterans have limited sensitivity in detecting some middle-ear disorders, and do not include a direct test of cochlear function. Recent studies have shown promise for new wide-bandwidth (WB) tests of absorbance for improved sensitivity in the assessment of middle-ear function including acoustic reflex testing. The addition of WB tests of cochlear function included in the WB test battery provides an opportunity to improve audiological diagnosis of a range of hearing disorders in Veterans. The automation provided by the WB test battery could provide additional benefits in reducing the duration of the evaluation, leaving more time for evaluation of test findings and counseling. Results from this study may lead to the improvement of audiological care for Veterans with hearing loss.
The objective of the trial is to investigate whether early treatment with oral valganciclovir of infants with both congenital cytomegalovirus infection and sensorineural hearing loss can prevent progression of hearing loss.
To test the effectiveness of body-worn, digital hearing aids, model 02 which is developed by the National Electronics and Computer Technology Center, Thailand.
The purpose of this study is to evaluate the central auditory processing in patients with bilateral sensorineural hearing loss and to observe the change of the central auditory processing ability after using hearing aids.
The purpose of this clinical study is to validate the comparability of prescription formula fitting of hearing aids based on full diagnostic audiometry and SelfFit interactive fitting of hearing aids based on hearing loss screening (mild to moderate hearing losses) using in-situ audiometry, provided and executed through the mobile medical app.
The purpose of this program of research is to understand the perception of the dynamic spectral properties of speech by hearing-impaired listeners, with the long-term goal of improving speech understanding by these individuals in adverse listening conditions. The proposed research compares the performance of normally-hearing and hearing-impaired listeners on measures of speech understanding in the presence of different types of signal distortion and speech understanding of signals with enhanced spectral dynamics. A computational model based on the amount of potential information available in speech will be used to quantify differences in speech intelligibility due to hearing status and stimulus characteristics.
