Active clinical trials for "Deafness"

In this study, the investigators will evaluate whether auditory training with speech-related acoustic features in psychophysical testing will help CI subjects improve speech recognition. The primary endpoint is the speech recognition measures.

The purpose of this study is to measure the potential effects of surgical drilling noise and/or vibration exposure on the hearing in the ear contralateral to the surgical site during skull-based surgeries

This study measures sounds produced by the sensory receptors of the inner ear called hair cells. These sounds are called otoacoustic emissions and one special case the investigators are studying are called distortion product otoacoustic emissions (DPOAEs) produced by presenting two tones to the ear. If the ear is damaged by noise exposure DPOAEs are reduced. In this study the investigators are attempting to improve the DPOAE test by adding a third tone to make the test more frequency specific. Whether the third tone helps will be determined by comparing DPOAEs collected with and without the third tone to clinical audiograms. If the addition of the third tone helps then the investigators expect DPOAEs tracked as a function of frequency (DP-grams) will more closely match the clinical audiograms.

The lyric hearing device is a commercially available device produced by Sonova, and designed to be used for extended periods of time. We further want to investigate the morphology of the tissue around the device at different periods of time after the device has been fitted and used for a while. An initial imaging of the tissue will be taken for baseline measurements. Questionnaires will also be used to assess patients satisfaction with the device and cognitive abilities.

The number of patients with cochlear implants increases every year, constituting an active queue increasingly important (60 new cases per year in Toulouse, active list in 2013: 380 adult patients). The number of approved cochlear implant centers is limited by guardianships, and corresponds to the Hospitals University. It is not possible to create networks of correspondents. Teams of implantation centers must meet the needs of new patients and ensure continuity of care for patients already implanted: speech therapy monitoring, adjustment and rehabilitation. In case of malfunction of the implant, patients use in first-line reference center. The increasing number of patients leads to a lack of specialized teams that can not meet the demands of patients in a timely manner, while continuing to provide support for new patients. It is therefore necessary to find solutions to improve the service provided to patients who received a cochlear implant system to respond quickly and effectively to the request of troubled patients, while optimizing the workload of the teams . The introduction of a telemedicine platform is expected to achieve these goals, distinguishing minor malfunctions, not requiring a consultation in a center, and the most complex situations requiring consultation in a center.

The aim of this retrospective study is to collect and assess hearing performance data that have been measured by five clinics in Germany as part of their clinical routine in recipients implanted with a commercial CI532.

Currently, the data from the literature do not evaluate the use of the middle ear implant in implanted patients in the medium term (10 years and over) but only in the short term (1-5 years). Based on the observation of the absence of these data, we considered it necessary to evaluate in the medium term the satisfaction of the patients carrying a middle ear implant and their rate of abandonment with a horizon of 10 to 20 years of apparatus.

Observational study about children with cleft palate from surgery to pre-adolescence :Description of language development and hearing profile.

Hypothesis: Treatment for head and neck tumors often involve methods that affect the auditory system and cause hearing loss. Neck dissection negatively impacts the lymphatic drainage, chemotherapy uses ototoxic drugs, radiotherapy affects blood flow and tissue radiation is toxic to the ear and may lead to hearing losses of various types and degrees. Objective: To investigate occurrences of hearing loss and complaints among patients with head and neck tumors who underwent radiotherapy. Study design: Prospective, case-control study. Setting: Tertiary care center hospital. Subjects and Methods: 282 subjects were evaluated, 141 with head and neck tumors and 141 as an age-matched control group. The controls had never undergone oncological treatment that put their hearing at risk. All subjects underwent audiological evaluation, including the HHIE questionnaire, pure tone audiometry, speech audiometry and immittance audiometry. The radiation dose received by the auditory system was calculated based on the percentage of the external auditory canal included in the radiation field.

There are no differences between the exams made with the new device,that evaluates the hearing, and the device gold standard, that is widely used in clinics and hospitals.
