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
Computer-assisted speech training is a speech recognition training system developed for cochlear implant users. With minimal facilities and skills, cochlear implant users can conduct this training at home. The purpose of this study was to apply this system to adolescent and young adult hearing aid users with prelingual severe to profound hearing loss.
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.
A bone anchored hearing system is used to improve hearing for patients with e.g. conductive/mixed hearing loss or single sided deafness. With this type of system, a titanium implant is installed in the temporal bone, where it osseointegrates, i.e. integrates with the bone. An abutment (also in titanium) is attached to the implants and penetrates the skin. The sound processor (hearing aid) is then connected to the abutment, and can be attached and removed by the patient via a snap-coupling. This type of system has been successfully implanted in more than 100.000 patients. Recently, a simplified surgical procedure, where no skin thinning around the abutment is made, was approved. The results after using this installation technique, here called soft tissue preservation, are the focus of this study. The objective of the study is to compare the outcomes after a surgical procedure with soft tissue preservation (test) and a surgery with soft tissue reduction (control) for placing Oticon Medical Ponto implants and abutments. The main hypothesis is that patient numbness around the implant is less in the test group compared to the control group.
Noise-induced hearing loss affects an estimated 5% of the worldwide population, with 30-40 million Americans exposed to hazardous sound or noise levels regularly. Sources of noise may be occupational, blast noise, or recreational. Trauma to the inner ear can occur through transient hearing loss or permanent hearing loss. Although hearing recovers after temporary transient hearing loss, growing evidence suggests that repeated temporary transient hearing loss may lead to a permanent hearing loss. Currently, there are no treatments and there are no known medications that can be used clinically to prevent noise-induced hearing loss in humans. The long-term goal of this research is to find medications that can prevent noise-induced hearing loss. The purpose of the present pilot study is to evaluate zonisamide and methylprednisolone as medications to prevent temporary transient hearing loss in humans.
The primary purpose of the study is to develop and test the preliminary efficacy of a first-in-kind community-based intervention to provide affordable, accessible and effective hearing health care to low-income, minority older adults.
The EarLens System is an assistive hearing device that is intended to provide amplification for the treatment of patients with sensorineural hearing impairment. The purpose of this multi-center definitive study is to assess the safety and efficacy of the EarLens System for subjects with bilateral mild to severe sensorineural hearing impairments wearing the fully activated system in their daily lives for a 4 month period of time. This study is designed to support US and International marketing applications to commercialize the EarLens System. The main efficacy hypothesis is that the EarLens System will be shown to improve speech understanding in quiet.
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.
Hearing loss screening rates in for older persons in primary care clinics are very low even though hearing loss is relatively common for older persons. When diagnosed with hearing loss older persons are often reluctant to follow through. This study involves a prospective controlled trial comparing the effectiveness of three primary care based protocols for older adults ≥ 60 who screen positive for possible hearing loss in promoting subsequent access to and use of hearing health care services. The protocols will compare: 1) screening only (standard care control); 2) screening plus an illustrated educational brochure; and 3) screening plus an in-person educational intervention and an illustrated educational brochure. Screening will be done by primary care personnel. Participants will be tracked for 8 months to assess outcomes.
