“…The mean gain in scores for the speech scale was 2.2 points, for the spatial scale 2 points, and for the qualities scale 1.9 points. These reported values were all very close to the mean SSQ gains recently reported in a larger cohort study of 291 unilaterally implanted adult subjects, consecutively recruited from multiple countries (Lenarz et al, 2017). Values obtained in the GBI also indicated that an overall benefit had been provided by the implant: The mean GBI total score was 28 ± 6, with significant gains in the general health subscale, but no improvement in the physical and social subscales.…”

Objectives: To report on electrode array measurements for the Nucleus ® CI532 Slim Modiolar Electrode device including: ECAP thresholds, electrode impedances, and psychophysical comfort levels, as well as speech perception results pre-and post-operatively and standardized evaluations of quality of life. Methods: Forty-four subjects were implanted with the CI532. Electrically evoked compound action potential (ECAP) thresholds and impedances were measured using automatic Neural Response Telemetry intraoperatively, at activation and at six months post implant. Pre-and post-operative measures of words in quiet and sentences in noise were made in multiple languages. Quality of life was assessed using The Speech Spatial Qualities questionnaire (SSQ) and Glasgow Benefit Inventory (GBI). Results: Intra-operative ECAP thresholds were recorded successfully from 90% of electrodes tested. ECAP thresholds varied across the array and a post-hoc Dunn's test showed that median thresholds for electrodes E1-E13 were significantly greater than those for E17-E22 (all P < 0.001). Impedances increased significantly between surgery and activation. Speech recognition scores for words in quiet and sentences in noise showed a significant improvement for the group at six months, when using the cochlear implant, compared with pre-operative performance (P < 0.001). There was a significant increase compared to pre-operative ratings for all sections of the SSQ at six months post activation (P < 0.001). The GBI gave scores significantly above zero for the 'general' subscale and total score. Conclusion: Objective ECAP and impedance measures for this new electrode array were as expected and similar to results reported for other array types. Speech perception and quality of life improved significantly following implantation. (Registered as NCT02392403 on ClinicalTrials.gov PRS)

“…The above work sums up and confirms previously marked and gradually published articles on the subject-matter along with data incoming to Poznań and cooperating centres. These publications demonstrate the benefits of improving the quality of life considered in various aspects of everyday life in patients treated with cochlear implants [27,28].…”

Introduction: Profound hearing loss significantly affects the quality of life of deaf people as well as their families. Observation of the benefit from the use of cochlear implants in deaf patients allows to assess the success of treatment with this method and its impact on the quality of life of these patients. The aim of this study was to determine the quality of life in patient after the cochlear implantation in the material of Department of Phoniatrics and Audiology of the Medical University in Poznań. Material and methods: The study involved implanted patients who voluntarily joined to the project entitled "Observational study of the implanted patient (Cochlear-IROS)". It has a prospective character, it is an international and long-term study, covering the observation of patients up to three years after implantation. Standardized HUI and SSQ questionnaires were used. 70 patients were included in the analysis, the mean age at the time of the cochlear implantation was 47.6 years. In the research group there were 33 men and 37 women. In the whole group, the patients' age at implantation was at least 18 years, max. 80 years. Results: The results of the SSQ questionnaire, which deals with the self-assessment of hearing ability in everyday situations, indicate that in the subjective assessment of patients one year after surgery the speech hearing improved by 77%, spatial hearing by 84%, and the quality of hearing by 49%. The general quality of life before the first connection of the sound processor according to the HUI questionnaire, the patients rated at 0.49 (0-1 scale, where 0 - corresponds to the death condition and 1 - full health). After one year from the implantation, this rating increased to 0.56. Conclusions: The implantation of the cochlear implant significantly increases the patient's quality of life, its physical and emotional functioning. Statistically significant better self-assessment of patients mainly concerned hearing speech and spatial hearing - especially after 1 year of connecting the speech processor.

“…The emotion questions asked if subjects were happy and interested in life and ranged down to very unhappy or so unhappy life is not worth living. The large utility gain of 0.18 recoded is equivalent to the gains recorded in a multinational survey of 291 bilaterally deafened but unilaterally implanted traditional CI patients, including patients with tinnitus and children over 10 years of age [Lenarz et al, 2017]. If we consider the baseline health status of the two groups, both had a utility score of 0.45.…”

Objective: To show that patients with unilateral hearing loss (UHL), with one ear fulfilling cochlear implant (CI) indication criteria, and an additional severe tinnitus handicap can be treated effectively with a CI. Method: A prospective multi-centre study was conducted in five Spanish centres. Sixteen adult patients with UHL and a mean Tinnitus Handicap Inventory (THI) score of at least 58 were implanted. The study design included repeated within-subject measures of quality of life (Health Utility Index Mark 3 [HUI3]), tinnitus (THI, Visual Analogue Scale [VAS] on tinnitus loudness), hearing (Speech, Spatial, and Qualities of Hearing Scale– [SSQ]), and hyperacusis (Test de Hipersensibilidad al Sonido [THS]) up to 12 months after the initial CI fitting. Results: Group data showed significant subjective benefit from CI treatment: the preoperative HUI3 total utility score of 0.45 went up to 0.57 at 6 months and 0.63 at 12 months; the preoperative THI total score of 75 decreased to 40 at 6 months and 35 at 12 months. The preoperative tinnitus loudness VAS score of 8.2 decreased to 2.4 at 6 months and 2.2 at 12 months with the implant “On” and to 6.7 at 6 months and 6.5 at 12 months with the implant “Off.” The preoperative THS total score of 26 decreased to 17 at 12 months. The preoperative SSQ total score of 4.2 increased to 5.1 at 6 months and 6.3 at 12 months. No unanticipated adverse events were reported during the study period. At 12 months after CI activation all subjects (except 1 subject who used the device 6 days a week) wore their devices all day and every day. The primary reason for CI use was split evenly between tinnitus suppression (n = 6) and both hearing and tinnitus (n = 6). Conclusion: A CI should be considered as a treatment option in patients with UHL and a concomitant severe tinnitus handicap. However, appropriate counselling of candidates on the anticipated risks, benefits, and limitations that are inherent to cochlear implantation is imperative.
