In patients with symmetric hearing loss who meet traditional cochlear implant candidacy criteria yet demonstrate pre-operative unilateral vestibular weakness, the choice of which ear to implant may impact their post-operative vestibular course. The investigators aim to implement both objective videonystagmography metrics as well as subjective patient-reported outcome measures to assess whether selecting laterality for cochlear implantation as it relates to unilateral vestibular loss has a measurable impact on patients' post-operative vestibular function. In pursuing cochlear implantation on the ear that demonstrates worse vestibular function, the investigators hypothesize improved vestibular function in comparison to operating on the unaffected side. The randomized control pilot study plans to allocate 10 subjects to a treatment group that involves cochlear implantation on the ipsilateral side of vestibular hypofunction and a control group that will undergo implantation on the contralateral side. The investigators plan to compare scores derived from the Dizziness Handicap Inventory completed at pre-operative evaluation and at two subsequent post-operative visits between control and treatment groups as primary outcome. The investigators also plan to determine if there is a significant difference in measures derived from caloric vestibular testing pre- and post-operatively as well as between control and treatment groups.

The goal of the HAHA trial is to prove that the treatment of HI and prevention of HI-related cognitive decline are most likely to be effective if HI is approached as a broader neurodegenerative entity with multifaceted manifestations currently unaddressed in clinical practice and managed using a novel individualised data-driven protocol for early hearing rehabilitation. The main hypothesis is that, compared with standard care, the data-driven rehabilitation will likely have broader benefits manifested in three key areas: hearing, cognition, and quality of life and psychosocial outcomes. Participants will be randomized 1:1 to either intervention (individualised data-driven hearing rehabilitation) or control group (standard care hearing rehabilitation). The primary objective of this study is to investigate the effect of an optimized data-driven hearing rehabilitation protocol versus standard care protocol on change in speech perception in noise (SPIN) in older adults with mild to moderately severe sensorineural HI and without dementia.
NCT06598059
This clinical study will test a new type of cochlear implant known as CI632D. This experimental cochlear implant has been designed to slowly release a drug called dexamethasone. Dexamethasone works to ease inflammation and reduce tissue injury, which is common after any type of surgery. The goal is to learn if the dexamethasone in the CI632D implant lessens these reactions inside the ear following surgery and if this makes the implant work as well, or even better, in improving hearing than what would be expected with a standard cochlear implant. 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 nerve that carries sound signals from the ear to the brain). The study participants will receive the CI632D experimental implant and will complete tests to see how well they are hearing and how well the implant is working.

In children aged 0 to 7 years, behavioral evaluation during cochlear implant programming is often difficult or unreliable. Objective, reproducible, and rapid markers are therefore essential. While objective measures such as ECAP (electrically evoked compound action potentials) help guide safe programming, they can show inter-electrode and inter-subject variability. Electrically evoked stapedius reflex threshold (eSRT) has emerged as a relevant objective marker to approximate the comfort level of stimulation. Pediatric studies indicate that eSRT can be measured in the majority of children, closely corresponds to the comfort level, and is associated with improved speech outcomes when programming is guided by eSRT. In our previous single-center study in children aged 8 to 17 years (N=30; 44 implanted ears), eSRT was obtained in 83.3% of patients, with strong correlation between C-subjective and C-eSRT thresholds (r\>0.94; p\<0.001) across all electrodes. Tonal performance remained stable, and speech intelligibility, particularly in noise (FraSiMat), significantly improved with an eSRT-based program after one month of habituation. Daily device use remained stable, reflecting good clinical acceptability. These results support the relevance of systematic integration of eSRT in routine programming. The aim of the eSRT2 study is to evaluate the feasibility and reliability of eSRT measurement in real-world clinical care for children aged 0 to 7 years, and to monitor its stability during post-operative follow-up. Improved auditory accessibility and better-controlled acoustic comfort through eSRT are expected to accelerate speech development in children by enabling earlier improvements in vocal performance and intelligibility.

NCT07388784
An exploratory investigation of gain precalculation principles in CE-labelled Sonova brand hearing instruments (e.g. Phonak hearing instruments) is intended to be conducted on hearing impaired participants. These gain precalculation principles are enabled by respective hearing instrument technologies and hearing instrument algorithms. The aim of the study is to investigate and assess strength and weaknesses of these gain precalculation principles in terms of speech intelligibility to determine their application in hearing instruments (Phase of development). Objective laboratory measurements as well as subjective ratings will be carried out. This will be a controlled, single blinded and randomized active comparator clinical evaluation which will be conducted mono centric at Sonova AG Headquarter based in Stäfa.
NCT00023036
This study will try to identify and understand the genetic factors that lead to an inner ear malformation called "enlarged vestibular aqueducts", that can be associated with hearing loss. Patients with sensorineural hearing loss with or without inner ear malformations and their parents and siblings may be eligible for this study. Participants and their immediate family members, may undergo some or all of the following tests and procedures: * Medical and family history, including questions about hearing, balance and other ear-related issues, and review of medical records. * Routine physical examination. * Blood draw or buccal swab (brushing inside the cheek to collect cells) - Tissue is collected for DNA analysis to look for changes in genes that may be related to hearing loss. * Hearing tests - The subject listens for tones emitted through a small earphone. * Balance test (VEMP) to see if balance functions of the inner ear are associated with the hearing loss Electrodes will be placed behind your ear and at the base of your neck. From a reclining position, you will be asked to raise your head while clicking sounds are played into your ears. - Ultrasound tests - An inner ear malformation called EVA (enlargement of the vestibular aqueduct) indicates that a genetic disorder called Pendred syndrome may be the cause. Because thyroid abnormalities are also associated with Pendred syndrome, an ultrasound examination of the thyroid gland may be done. * Computed tomography (CT) and magnetic resonance imaging (MRI) scans - These tests show the structure of the inner ear. For CT, the subject lies still for a short time while X-ray images are obtained. For MRI, the patient lies on a stretcher that is moved into a cylindrical machine with a strong magnetic field. The magnetic field and radio waves produce images of the inner ear. The radio waves cause loud thumping noises that can be muffled by the use of earplugs.

Children who are deaf or hard-of-hearing (D/HH) are at risk of speech and language delays, which can be mitigated through early identification and intervention. Identifying hearing loss (HL) during preschool is crucial, but the most effective hearing screening method for preschoolers remains uncertain. The purpose of this study is to learn whether, compared to the gold-standard two-stage Pure-tone audiometry (PTA) + otoacoustic emissions (OAE) screening (TS-PO), single-stage OAE (SS-O) screening alone is not inferior at identifying hearing loss when performed in a community-based preschool setting. This study holds the potential to improve early hearing loss detection and intervention among D/HH children, reducing the likelihood of speech and language delays. A diverse group of 13,764 preschool-age children across community-based preschool centers will be recruited. The intervention involves all subjects undergoing both PTA and OAE screening, with the order determined through randomization. Children who show potential hearing issues based on screening results or teacher concerns will receive further testing to determine the final hearing outcome. Group allocation will be post-hoc, based on their screening results. In addition to the primary objective, the study will compare other hearing screening measures and outcomes between the two methods (TS-PO and SS-O). This approach aims to reflect the real-life effectiveness of hearing screening in a diverse population. Ultimately, the study seeks to provide insights into an optimal hearing screening method that could prevent speech and language delays among D/HH children.
NCT07222202
Conductive hearing loss (CHL) is the most common type of hearing loss among the pediatric population. CHL occurs when sound is not properly transmitted from the external ear to the cochlea, and congenital pathologies like microtia/anotia, atresia, and absent or malformed ossicles make hearing loss permanent.
NCT07218913
This phase I trial evaluates whether adding Pedmark to standard of care cisplatin-based chemotherapy reduces drug-induced ear damage (ototoxicity) in men with stage II-III testicular germ cell tumors that have spread from where they first started (primary site) to other places in the body (metastatic). Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Cisplatin-induced ototoxicity remains a major concern in adult patients with germ cell tumors as nearly four out of five patients develop hearing loss after treatment. Cisplatin is thought to cause ear damage by the production of chemically reactive molecules called reactive oxygen species. These molecules can cause damage when their levels get too high. Pedmark may reduce the negative side effects of cisplatin by neutralizing these reactive molecules. Pedmark has been approved for reducing the risk of cisplatin-induced ototoxicity in pediatric patients and older patients with solid tumors that haven't spread to other parts of the body. Adding Pedmark to cisplatin-based chemotherapy treatment may reduce ototoxicity in adult men with stage I-III testicular metastatic germ cell tumors.

NCT07200310
This study looks at whether working as a hot-air balloon pilot-being exposed to burner noise, changes in air pressure/temperature, and vertical acceleration-is linked to changes in hearing, Eustachian tube function, and vestibular (balance) function. Adult pilots from Cappadocia will be compared with adults who do not have these exposures. Approximately 90 participants are expected to be enrolled For contextual exposure information, representative in-field noise measurements during balloon operations and basic flight parameters may be documented Each participant will attend one visit (\~60 minutes) in an ENT/audiology laboratory. After a short questionnaire and an ear exam (otoscopy), the following non-invasive tests will be performed: tympanometry; tympanometry with simple maneuvers (Valsalva/Toynbee) to evaluate Eustachian tube function (ΔTPP); pure-tone audiometry (including extended high frequencies); otoacoustic emission tests (TEOAE and DPOAE); acoustic (stapedius) reflex thresholds; and a brief cervical vestibular evoked myogenic potential (cVEMP) test. Symptom-triggered questionnaires will also be used: for participants reporting tinnitus, the Tinnitus Handicap Inventory (THI); for those reporting dizziness, the Berg Balance Scale (BBS). No medications or blood tests are involved. Testing is safe and routinely used in clinical care. Risks are minimal (for example, temporary ear-canal pressure or brief dizziness). Testing will be stopped if any discomfort occurs. Personal information will be kept confidential, and results will be reported only in group form. Findings from this study may help improve occupational health guidance for hot-air balloon pilots.
NCT05552118
The aim of the study is to assess the real-world effectiveness of managing participants within the first year post-activation (between 3 and 12 months) using Cochlear's Remote Care (Remote Check and Remote Assist), as compared with standard in-clinic management. The study captures also the time and costs associated with both models of care to quantify the potential costs savings and efficiency gains possible with delivering Cochlear Implant (CI) aftercare remotely.
NCT06477354
ACEMg (Soundbites) is a neuroprotectant supplement designed to block the initiating biological events in the inner ear leading to inner ear hearing loss, sensorineural hearing loss, SNHL, which accounts for more than 90% of all hearing loss. SNHL is so common it is called hearing loss. There is no cure for SNHL. The 24-week OTIS Study aims to validate findings from the previous two-year real-world study demonstrating ACEMg (Soundbites) preserved or improved auditory function (hearing) for 75.3% of participants who used it daily, with most improvement occurring within six months. The study also aims to assess the potential of ACEMg to relieve tinnitus, hyperacusis, and hearing sensitivity symptoms. These symptoms are often correlated with SNHL; relief from tinnitus, hyperacusis and hearing sensitivity were were not measured in the previous two-year study. The OTIS study aims to answer two questions. First, does the real-world data demonstrate that hearing loss is stabilized or improved at the end of the test among participants with SNHL at the beginning? Second, do participants who self-report tinnitus, hyperacusis, or hearing sensitivity symptoms at the start of their test report reduced symptoms at the end? Participants must be eighteen years of age and older and self-report hearing loss and/or tinnitus. The study is conducted at home using a smartphone app and a web-based assessment and data reporting tool developed for this study. The study is conducted at home using an online hearing test and short surveys on tinnitus and hyperacusis. The tests are completed three times: Baseline tests are taken before participants begin to take ACEMg softgel capsules daily. The Test is repeated at about 11 and 24 weeks. Assessment scores at the beginning of the study will be compared with scores at the end. Participation in the study is free.

NCT06556160
In humans, surface electrophysiological recording of the cochlear nerve in response to a sound stimulus provides information about the integrity and function of synapses (synaptic transmission) and nerve fibre function. However, this information remains global. The investigators have preliminary data showing that it is possible to extract and characterise the functional properties of nerve fibres during otoneurosurgery in humans, and therefore to isolate the neuronal sub-populations mentioned above more precisely than is currently possible. The use of these electrophysiological data from near-field recordings, i.e. in contact with the nerve, will enable the design and improvement of a mathematical model of the human cochlea. This model will provide access to the individual responses of each nerve fibre and fill the current gap in knowledge between the functioning of these fibres and global surface recordings.
