NCT06268340
The goal of the study is to determine the benefit of using an ECochG-based corrective action guide during cochlear implant surgery compared to the traditional surgical approach without ECochG surveillance and guidance.
NCT06051006
One of the most significant challenges in cochlear implant programming, particularly for very young children and those with an associated pathologies, is the measurement of subjective comfort levels (= C-Subjective). Currently, to define this C-Subjective level, patients are presented with a loudness scale and must indicate whether the sound stimulus, sent via the implant, is soft, comfortable, or loud. The lower and upper stimulation levels must be determined for each electrode in order to program the implant. For many patients this can be difficult due to a lack of auditory experience and confusion between the sensation of sound intensity (weak or loud) and frequency (low or high). A less commonly used but more objective approach to programming upper stimulation levels involves the use of the electrical stapedial reflex threshold (eSRTs) value. eSRTs are a promising measure, given the demonstrated correlation between the threshold that generates a stapedial reflex and the C-subjective level. Furthermore, eSRTs can be recorded in the majority of patients, and can typically be evoked at a comfortable stimulation level i.e. inferior to the uncomfortable level. The main objective of this study is investigate the link between subjective comfort levels (C-subjective levels) and the eSRT.
NCT02203305
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.
NCT04222296
The study will involve the comparison of three groups with severe-profound hearing loss. Patients with a Cochlear Implant only, patients with a cochlear implant and Hearing Aid, and finally patients with two hearing aids. This will enable a comparison of standard fitting protocols against the new rationale using the same devices. Devices used for patients in all 3 groups are now available in standard of care, and can be kept afterwards should the patients wish.
