To evaluate whether the second cochlear implant (CI) provides any extra benefit with respect to health-related quality of life, tinnitus, and auditory abilities.
The data were evaluated using validated questionnaires before and after the first and second CI supply. Preimplantation data were collected retrospectively.
Forty postlingually deafened adults, 11 male and 29 female subjects were included in this study. All patients were sequentially bilaterally implanted with a multi-channel CI for at least 6 months.
The health-related quality of life assessed with the Nijmegen Cochlear Implant Questionnaire further increased after the second CI. In patients with initially higher level of tinnitus annoyance measured with the Tinnitus Questionnaire, the scores decreased after the first CI and remained steady after the second CI. Patients with initially lower level of tinnitus annoyance had a further decrease of the Tinnitus Questionnaire score after the second CI. Additionally, the second CI induced further improvement of auditory abilities, as assessed by the Oldenburg Inventory and the Freiburg monosyllable test in quiet and the HSM and Oldenburg sentence tests in noise. The quality of life scores correlated with the auditory abilities, especially after the second CI.
The present study provides evidence that the second CI leads to further increase in quality of life and reduction of tinnitus annoyance in addition to improvement of auditory abilities as compared with the first CI. Patients with bilateral CIs benefit from additional positive effects in all these fields.
评估第二人工耳蜗（CI）植入相对于健康相关生活质量、耳鸣和听觉能力是否有额外获益。
使用经过验证的问卷，在第一和第二次 CI 植入前后评估数据。植入前数据是回顾性收集的。
40 名后天失聪的成年人，包括 11 名男性和 29 名女性，纳入本研究。所有患者均顺序双侧植入多通道 CI，植入时间至少 6 个月。
使用奈梅亨人工耳蜗植入问卷评估的健康相关生活质量在第二次 CI 后进一步提高。在最初耳鸣困扰程度较高的患者（使用耳鸣问卷测量）中，第一次 CI 后评分下降，第二次 CI 后保持稳定。最初耳鸣困扰程度较低的患者在第二次 CI 后耳鸣问卷评分进一步下降。此外，第二次 CI 诱导听觉能力进一步改善，使用奥登堡听力测试和安静时的弗赖堡单音节测试以及 HSM 和奥登堡句子测试在噪声中进行评估。生活质量评分与听觉能力相关，尤其是第二次 CI 后。
本研究提供了证据，表明与第一次 CI 相比，第二次 CI 除了改善听觉能力外，还能进一步提高生活质量和减轻耳鸣困扰。双侧植入 CI 的患者在所有这些领域都受益于额外的积极影响。
