Filter by:Severe to profound hearing loss affects 0,8% of the global population. For these people, a conventional hearing aid often does not provide sufficient benefit. However, these people can benefit from a cochlear implant (CI). A CI needs to be individually programmed (fitted) for each recipient. A fitting "map" is defined as a set of electrical parameters that are individually adapted to a recipient's needs to achieve optimal sound perception. At present, most CI recipients are fitted with a default frequency allocation map that doesn't take individual variability in size and shape of the cochlea into account. In this study, a fitting strategy based on the post-operative CT scan, that will allow the audiologist to set a frequency-band distribution for CI fitting that may be more closely aligned to the natural tonotopic frequency distribution of a normal hearing cochlea, will be evaluated.
Hearing loss is a major cause of disability that affects over 48 million Americans. There are currently no medications used to treat sensorineural hearing loss. Cochlear implants can significantly restore hearing in adults with moderate to profound sensorineural hearing loss, but their utility is limited by the wide variability in hearing outcomes. Differences in cochlear implant outcomes may be explained by neuroplasticity, as neural networks must reorganize to process the new auditory information provided by the implant. The investigators predict that cholinergic enhancement with donepezil (an acetylcholinesterase inhibitor) may facilitate cortical reorganization in cochlear implant users, leading to functional improvements in speech recognition and cognition. In addition to taking donepezil, study participants will be asked to increase their daily processor use. Studies suggest that increasing daily device use can improve speech recognition, and this study will explore whether this effect can be augmented further with donepezil. In this randomized, double-blind controlled trial, the investigators aim to assess the effects of donepezil on speech recognition, cortical plasticity, and cognition. Participants will start daily treatment with either donepezil 5 mg or placebo. Participants will be followed longitudinally at 1 month and 3 months after starting the study. The findings from this study will provide important insight into the mechanisms of hearing restoration and could potentially improve hearing and cognitive outcomes for future cochlear implant users.
Vestibular loss can co-occur with hearing loss causing dual sensory deficits. This project examines vestibular loss as a contributing factor to reading difficulties for children with hearing loss, where previously only the effects of hearing loss and subsequent language difficulties have been considered. These results are expected to influence the identification and habilitation of vestibular loss in children with hearing loss.
Migraine and sudden sensorineural hearing loss(SSNHL) are two related disorders. A systemic steroid is usually used to treat SSNHL but the role of migraine prophylaxis medication remained unknown. Mehdi Abouzari et al. found a better improvement when combining topiramate and nortriptyline with steroids in a retrospective study. However, a prospective study with randomization is needed to elucidate the efficacy of these agents. This is a clinical study using medication approved and currently prescribed in the clinic. The included patients were those who came to the clinic and were diagnosed with SSNHL within 14 days of onset. Those patients were asked whether they agreed to participate in this clinical trial. Patients who were diagnosed with SSNHL but were later found to be other diseases such as Meniere's disease and cerebellopontine angle will be excluded from this study. The involved patients were randomized divided into two groups. Both groups received systemic steroids with/without intratympanic steroids. The experimental group receives additional oral topiramate for 6 weeks. Follow-up time is at least 3 months. This study is multi-center. Location of the study is performed at Chang gung memorial hospital Linkou branch, Taipei branch, Taoyuan branch, and New Taipei Municipal Tucheng Hospital.
Cochlear fibrosis development can compromise the success and the outcomes of the cochlear implantation (CI) thus affecting the quality of life of the implanted patient. Correlating the results of the Transimpedance Matrix (TIM) measurements to the implant electrode location determined by the Cone Beam Computer Tomography (CBCT), this study aims to identify a range of TIM profiles within the implanted population, certain profiles suggesting the growth of the fibrosis tissue in cochlea
The purpose of this study is to follow the natural history of non-syndromic hearing loss caused by mutations in two genes (GJB2 or OTOF) in children up to 10 years of age.

This study will focus on patients that are already implanted with the HEARO robotic system.
The main objective of this study is to assess the effectiveness of an integrated program of fitting and training interventions aimed at reducing unexpected variability and addressing the specific error patterns of each recipient. The participants will undergo 1 visit lasting approximately 2 hours at the Radboud university medical center's ENT department, where they will undergo a series of diagnostic tests. Some of the participants will also be asked to self-administer additional tests using a Windows tablet. Based on the outcomes of speech recognition tests in quiet at the first visit, the participants will be called for follow-up interventions concerning both the fitting of their CI and personalized auditory training based on their personal error patterns. These interventions will take place over the course of approximately 5 months and will be made up of three follow-up visits and a period of self-administered training through a mobile application on a tablet. One final follow-up visit will check whether any changes from the interventions are retained after four weeks.
The aim of this study is to establish the connection between the cochlear implant programming parameters with the auditory effort associated with the speech perception evaluated by pupillometry techniques in different audiometric conditions.
Main objective: Compare the recognition of environmental sounds with an anatomy-based fitting and with a default fitting adult patients newly implanted with a MED-EL cochlear implant. Secondary objectives: Compare speech recognition in quiet with an anatomy-based fitting and with a default fitting in adult patients newly implanted with a MED-EL cochlear implant. Compare speech recognition in noise with an anatomy-based fitting and with a default fitting in adult patients newly implanted with a MED-EL cochlear implant.
