Active clinical trials for "Hearing Loss"

The primary goal of this project is to determine whether subjects with Single-Sided Deafness (SSD) experience an improvement in speech perception, localization, and quality of life with a cochlear implant as compared to an unaided listening condition.

The rationale behind this post-market clinical follow-up investigation is to collect data regarding the usability and clinical performance of the Baha Attract System in subjects with hearing impairment that are candidates for Baha surgery: to evaluate the efficacy of the Baha Attract System in terms of hearing performance compared to the unaided situation and compared to a pre-operative test situation using the sound processor on a Baha Softband; to evaluate the mid- and long-term safety of the Baha Attract System.

The study compares two different operative techniques for placement of the Cochlear Bi300 implant to be used for bone anchored hearing aid. The operative techniques to be compared are Dermatome technique with soft tissue reduction Linear incision with minimal or no soft tissue reduction The hypothesis is that the operative techniques are comparable with regard to implant stability, soft tissue healing and loss of sensibility around the implant. To evaluate the evolution of implant stability during the early healing period after implantation, which is the most critical period for osseointegrated implants, in particular when early loading protocols are used. To compare soft tissue healing around Baha implants placed according to the recommended surgical technique with skin transplant and Baha implants without performing skin reduction. To compare the loss of sensibility of the skin around the Baha implant (some loss of cutaneous sensibility nerves in the transplant procedure) between the two surgical procedures. While the study focuses on the early healing period (3 months), long-term safety data will also be collected after 6 months and 1-year. The study will also evaluate the change in health status produced by the surgical intervention.

The purpose of this study is to determine whether ancrod is effective and safe in the treatment of sudden sensorineural hearing loss (SSHL).

Clinical study to evaluate the safety and efficacy of the Cochlear™ Nucleus® CI422 cochlear implant for new cochlear implant adult recipients with broader requirements to be considered an eligible candidate.

The University of Sao Paulo Department of Otorhinolaryngology developed prototypes for a digital new hearing aid with an integrated sound generator. These prototypes assist both hearing rehabilitation (about 10% of the population) and tinnitus sufferers (about 17% of the population). Currently, the Brazilian Public Heath Care does not have any such hearing aids. So, the development of devices for the hearing rehabilitation as well as the treatment of tinnitus represents an advance in the implementation of Public Policies in Brazil. The aim of this study is to compare the efficacy of the hearing aid with an integrated sound generator and amplification alone for tinnitus control in patients with tinnitus associated hearing loss.

Speech understanding in noise remains the greatest challenge for people using cochlear implants, particularly when the speech of interest comes from the side of the head opposite to the implant. Recent findings in hearing technology allow for people to either use a hearing aid or a Contralateral Routing of Signal (CROS) device on the non-implanted ear. Differences in speech understanding may result depending on the device chosen by a person, and these differences may be measureable through speech discrimination measurement methods. This study intends to determine whether or not a CROS device improves speech perception in noise when the source of the speech of interest originates from the side of the head opposite to the implant.

This study evaluates the benefits of short-term training via telehealth for post-lingually deafened adult cochlear implant users. Half the participants will receive aural rehabilitation and the other half cognitive training. The hypothesis is that short-term aural rehabilitation via telerehab technology will improve outcomes for post-lingually deafened cochlear implant users

Hearing aids are being fit on inexperienced hearing aid users and the short-term and long-term effects are measured. This research aims to improve understanding of the individual factors that contribute to receiving benefit from hearing aids and lead to more individualized treatment of hearing loss.

This prospective study is a randomized, double-blind, placebo-controlled Phase 3 clinical trial of oral D-methionine (D-met) to reduce noise-induced hearing loss (NIHL) and tinnitus. The goal of the study is to develop a safe, oral pharmacological agent to augment physical hearing protectors for noise exposures that exceed the protective capabilities of ear plugs and/or muffs. The study population is a cohort of Drill Sergeant (DS) instructor trainees during and 22 days after their 11 day weapons training. The primary objective of this study is to determine the efficacy of D-met in preventing NIHL or reducing tinnitus secondary to a minimum of 500 rounds of M-16 weapons training occurring over an 11 day period.
