The purpose of the feasibility study is to investigate hearing performance (audiometry and speech perception) using the CI624 in a group of adults (n=15) with low-frequency residual hearing who meet inclusion criteria.
The main objective of this study is to evaluate the correspondence between eCochG and residual hearing by adding two modifications. First, a novel technique for placing and maintaining the probe in place during the whole insertion will be used. Second, a new metric for estimating the eCochG response will be evaluated (eCochG trauma index). The secondary objective is to find other markers of the cochlear trauma insertion associated to eCochG measures. This will be used to evaluate to which extend a traumatic insertion will be deleterious for the patient's post-operative hearing, and ultimately to prevent trauma to the inner ear. Finally, the potential differences in cochlear trauma resulting of the electrode array insertion from two different surgery techniques will be investigated; Either using a manual insertion or using a robotic arm that will drive the insertion automatically.
36 patients will be enrolled in a pilot trial. Eligible patients (receiving CI at OSU) that consent to participate into the study will be enrolled. A simulation with visualize cochlear substructures will be created for each patient, and surgeon will conduct virtual surgery with various cochlear implant electrode types and using different techniques for optimal positioning. Based on the feedback from the simulation platform, the surgeon will find the optimal CI electrode and surgical technique using the virtual simulation and a formal plan will be recorded to guide the actual surgery. Patient demographic information, medical history and pre op audiogram will be collected once enrolled. Post-op images will be used to identify the actual electrode location (scalar location (SL), modiolar distance (MD) and and angular insertion depth (AID). At 6- and 12-months post-op, word score (CNC) will be obtained as primary clinical outcomes and AZBio scores will also be obtained and evaluated as a secondary clinical outcome. All outcomes data to be collected for SA3 are considered as part of routine clinical care for patients undergoing CI at our institution. The prospective data collection plan will ensure these data will be collected timely with high quality. OSU IRB approval has been obtained for this study (OSU IRB# 2020H0080: Virtual Reality simulation for patient specific surgical rehearsal in cochlear implantation - OSU#2) pending additional amendments as needed.
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.
The primary objective of this study is to obtain a greater understanding of the range in benefit from acoustic amplification combined with electric stimulation in cochlear implant recipients with low-frequency hearing who do not currently use the commercially approved Advanced Bionics Acoustic Earhook. The aims of this study are to 1) obtain subjective sound quality judgements of recorded speech and music samples, 2) assess vocal emotion perception, and 3) evaluate post-operative speech perception and sound field detection thresholds in CI recipients both with and without use of the acoustic ear hook.
Main objective: Investigate how the FineHearing strategy of the MED-EL cochlear implant can extract prosody based solely on the frequency of the voice fundamental (F0) in speech Secondary objectives: Evaluate the time evolution of the results of prosodic tests Evaluate the time evolution of the results of differential frequency threshold test Evaluate the time evolution of vocal audiometric tests in silence and noise Evaluate the correlation between prosodic test results and frequency differential threshold results
Cochlear implantation is performed in children with sensorineural hearing loss to restore hearing. Fifty percent of children with sensory neural hearing loss, who are candidates for cochlear implant, have vestibular (inner ear) dysfunction prior to surgery. Anatomically, the cochlea, semicircular canals, and otolith organs are located in close proximity in the inner ear and any procedure in the cochlea may affect the vestibular system, resulting in subsequent balance impairment. In addition, the process of implantation often results in further suppression of vestibular function necessary to develop normal balance. Vestibular dysfunction predisposes these children to balance impairments that can affect the normal development of gross motor skills such as sitting, standing, and walking. These balance and gross motor deficits may predispose the child to difficulties with safe community participation resulting in lower quality of life for the child and family. Evidence in the literature suggests that children with vestibular loss do not recover to the same levels as their peers, especially in the area of activities requiring vestibular input for balance. The purpose of this descriptive study is to examine balance, vestibular function, and gross motor skills in children following cochlear implantation over a period of one year. Children, ages 1 year to 5 years will be tested post cochlear implant , and at 6 and 12 months subsequent to initial testing, using clinically based tests of vestibular impairment (head impulse test, post rotary nystagmus or head shake nystagmus), balance (Pediatric Balance Scale) and gross motor skill development (Peabody Developmental Motor Scales, 2nd edition). Quality of life will be assessed using the Life-H (Assessment of Life Habits).
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.
