Filter by:This clinical study will test a newly developed cochlear implant known as CI622D. This experimental cochlear implant has been designed to slowly release a drug called dexamethasone. Dexamethasone works to ease inflammation, which is common after any surgical procedure. The goal is to learn if there are added benefits in implant performance and hearing outcomes with the dexamethasone-releasing cochlear implant (CI622D) vs. the standard cochlear implant (CI622) without dexamethasone. The study will be conducted in adults with sensorineural hearing loss, a type of hearing loss caused by damage to the inner ear or auditory nerve. The study participants will undergo a series of tests that include testing their implant and their hearing. They will also complete questionnaires to see how they rate their hearing ability and their overall general health.
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.
This is a feasibility study for a inner ear catheter which will be used to apply steroids to the inner ear. It will be used on nearly deaf patients during their surgery, when they receive an implant that will restore the hearing. Treatment with steroids will improve the maintenance of residual hearing, which will be tested during and after the surgery.
This trial is a monocentric, prospective and controlled study of the pupil response to detect hearing threshold and comfortable loudness of normal-hearing (NH) and CI-subjects.
This study is to build a cohort of sudden sensorineural hearing loss (SSNHL) patients. When the patient visited the Department of otolaryngology clinic for hearing loss, we can diagnose the SSNHL following the result of pure tone audiometry and the history of the patient. The cohort is a system that tracks the hearing recovery status, timing, and degree of recovery of patients who received cocktail therapy with or without high-dose steroids, vasodilators, antiviral agents, and intratympanic steroid injections, satellite ganglion block, and hyperbaric oxygen therapy.
Hearing comprehension under complex listening conditions is considered to be the central complaint of everyday life for patients with cochlear implants. Localization is one of the cues for listening comprehension. However, only few studies have investigated the effect of spatial localization training on listening comprehension performance in noise. None of these studies correspond to the desire to purpose training by speech therapists while using affordable equipment. The main objective of this study is to evaluate the effect of a spatial localization training protocol in cochlear bi-implanted subjects with post-lingual deafness on their ability to understand in noise. 2 groups of 10 subjects each will be recruited: a patient group and a control group. The patient group will undergo 8 sessions of spatial localization rehabilitation lasting an average of 45 minutes each. After this programme, the pre-test and post- test results obtained will be compared.
This observational study evaluates the effects of cochlear implantation in patients with deafness in one ear.
Hearing-aid (HA) users with insufficient HA may be better helped with a "Bimodal solution" when replacing the HA with a Cochlear implant (CI) to the poorer hearing ear and a HA to the better hearing ear. This randomised controlled trial can show the benefit in terms of better speech perception of the bimodal solution with CI to the poorest hearing ear compared to binaural hearing aids. It can clarify if HAs users with insufficient HAs benefit will benefit from the bimodal solution when adding a CI to the poorer hearing ear in terms of better speech perception. It can report the degree of perceived hearing handicap in bimodal CI-users versus bilateral HA-users by hearing -specific patient reported outcome measures (PROM) questionnaires. And it can contribute to a specific cochlear implant candidacy criterion related to the transition from HA treatment to the CI treatment. The purpose of this study is to determine if bimodal treatment with a hearing aid to the better hearing ear and CI to the poorer hearing ear increases the ability to understand speech and improve quality of life compared to patients that are treated with hearing aids only. The benefit of bimodal fittings compared to the best possible bilateral HA treatment will be evaluated.
In France, children cochlear implantation (CI) is performed 400 times per year. Causes of profound sensorineural hearing loss (SNHL) are represented by congenital malformation of the inner ear for 50 to 60%. Most of the remaining cases of CI in children are caused by congenital CMV infection. The proportion of CMV inducing SNHL with a CI in children is not clearly defined. During CI, we aim to collect a very small sample of perilymphatic fluid and to analyse it with a CMV polymerised-chain-reaction to evaluate the involvement of CMV in SNHL.
The aim of the study is to evaluate the interaural time difference (ITD) benefit in patient with bilateral cochlear implants and to assess speech performance in noisy conditions compared to normal hearing listeners. Half of participants are bilateral cochlear implants users, while the other are normal hearing listeners.
