“…The mean improvement from baseline to 6 months post activation was 54% in quiet and 40% in noise. These results are comparable to studies that used the same sentence materials and presentation levels in adult CI users [11][12][13]. Of course, comparisons between studies should be done with caution given the large interindividual variability in CI outcomes as well as methodological differences.…”

“…As expected, HINT performance typically increases considerably after CI activation; for how long the performance continues to improve post-activation before reaching a plateau is variable but is most likely to be at least 1 year [11,12]. One year after activation, typical scores of adults with postlingual deafness tested in a CI-only condition with English HINT sentences presented at 60 dB SPL range from 69 to 74% in quiet [12,13,13] and from 54 to 61% in 70 dB noise, equivalent to a + 10 dB signal-to-noise ratio (SNR) [11,13]. In the Zwolan et al study [13], HINT sentences were presented from the front (0-degree azimuth) and speechshaped noise was presented from the CI side (90-degree or 270-degree azimuth), while the Cusumano et al study [11] presented both sentences and speech from the front.…”

“…The post-operative scores were measured with the CI only and with both the HINT sentences and the noise coming from the same loudspeaker. Two studies report HINT in noise results: in Zwolan et al [13], the sentences and the noise were presented from different loudspeakers (spatially separated), while the sentences and noise were co-located in Cusumano et al [11], as in the present study. Factors such as interindividual variability and spatial release from masking are known to affect sentence identification test scores [24].…”

A recent study reported the monosyllabic word identification scores in quiet and in noise of 44 adult Neuro CI system users [14]; however, the sentence identification scores of Neuro CI system users has yet to be reported.…”

Objective: This prospective longitudinal cohort study at six tertiary referral centers in Canada and Denmark describes the clinical efficiency and surgical safety of cochlear implantation with the Oticon Medical Neuro cochlear implant system, including the Neuro Zti implant, the EVO electrode array, and the Neuro One sound processor. Methods: Patients were adult cochlear implant candidates with bilateral sensorineural hearing loss. Results: The mean HINT scores in quiet pre-operatively and at 3, 6, and 12 months post-activation were 13%, 58%, 67%, and 72%, respectively, and in noise (+10 dB SNR) 13%, 46%, 53%, and 59%, respectively. The mean improvement from baseline to 6 months post-activation was 54% in quiet and 40% in noise. The surgical major complication incidence rate was 0% and the post-surgical major complication incidence rate (until 12 months post-activation) was 4%. There was no adverse event that was fatal, that required explantation, or that resulted in sound processor nonuse, and no implant failure. Conclusion: Cochlear implantation with the Oticon Medical Neuro system enables speech identification both in quiet and in noise and audiologic outcomes continue to improve in the year following activation. No substantial adverse events occurred during the surgical implantation procedure and during the 12 months post-activation.

“…Runge et al reported a mean 12‐month unilateral CNC word score of 52.9% in a group of 38 postlingually deafened adults with a traditional long electrode array. Cusumano et al completed a retrospective review of outcomes in pre‐ and postlingually deafened adults. For the 102 postlingually deafened adults, the mean 12‐month CNC word score was 57.6%.…”

ImportanceStandard-of-care treatment proves inadequate for many patients with bilateral vestibular hypofunction (BVH). Vestibular implantation is an emerging alternative.ObjectiveTo examine patient-reported outcomes from prosthetic vestibular stimulation.Design, Setting, and ParticipantsThe Multichannel Vestibular Implant (MVI) Early Feasibility Study is an ongoing prospective, nonrandomized, single-group, single-center cohort study conducted at Johns Hopkins Hospital that has been active since 2016 in which participants serve as their own controls. The study includes adults with severe or profound adult-onset BVH for at least 1 year and inadequate compensation despite standard-of-care treatment. As of March 2023, 12 candidates completed the eligibility screening process.InterventionThe MVI system electrically stimulates semicircular canal branches of the vestibular nerve to convey head rotation.Main Outcomes and MeasuresPatient-reported outcome instruments assessing dizziness (Dizziness Handicap Inventory [DHI]) and vestibular-related disability (Vestibular Disorders–Activities of Daily Living [VADL]). Health-related quality of life (HRQOL) assessed using the Short Form-36 Utility (SF36U) and Health Utilities Index Mark 3 (HUI3), from which quality-adjusted life-years were computed.ResultsTen individuals (5 female [50%]; mean [SD] age, 58.5 [5.0] years; range, 51-66 years) underwent unilateral implantation. A control group of 10 trial applicants (5 female [50%]; mean [SD] age, 55.1 [8.5] years; range, 42-73 years) completed 6-month follow-up surveys after the initial application. After 0.5 years of continuous MVI use, a pooled mean (95% CI) of within-participant changes showed improvements in dizziness (DHI, −36; 95% CI, −55 to −18), vestibular disability (VADL, −1.7; 95% CI, −2.6 to −0.7), and HRQOL by SF36U (0.12; 95% CI, 0.07-0.17) but not HUI3 (0.02; 95% CI, −0.22 to 0.27). Improvements exceeded minimally important differences in the direction of benefit (exceeding 18, 0.65, and 0.03, respectively, for DHI, VADL, and SF36U). The control group reported no mean change in dizziness (DHI, −4; 95% CI, −10 to 2), vestibular disability (VADL, 0.1; 95% CI, −0.9 to 1.1) or HRQOL per SF36U (0; 95% CI, −0.06 to 0.05) but an increase in HRQOL per HUI3 (0.10; 95% CI, 0.04-0.16). Lifetime HRQOL gain for MVI users was estimated to be 1.7 quality-adjusted life-years (95% CI, 0.6-2.8) using SF36U and 1.4 (95% CI, −1.2 to 4.0) using HUI3.Conclusions and RelevanceThis cohort study found that vestibular implant recipients report vestibular symptom improvements not reported by a control group. These patient-reported benefits support the use of vestibular implantation as a treatment for bilateral vestibular hypofunction.
