Abstract

Purpose: A real-world study of the Ultra cochlear implant was completed in 2022, aiming to compare preoperative and postoperative performance. The use of two different electrode arrays and their ability to preserve residual hearing were also investigated.

Methods: a total of: 78 subjects were enrolled in this study. All participants completed the preoperative baseline assessment and postoperative speech and hearing tests. Subjective questionnaires were administered to participants under 6 years old. The development of impedance and M-levels over time was also analysed. For participants older than 6 years of age, pure tone audiometry was performed to evaluate hearing preservation.

Results: The postoperative average aided hearing threshold and speech test results showed a statistically significant improvement compared to preoperative results (p < 0.05). No significant difference was observed between the two electrode arrays (p > 0.05). Overall, impedance and M-levels showed typical trends of progression. Most participants obtained good hearing preservation, while no significant difference in hearing deterioration was reported between the two electrodes (p = 0.20).

Conclusion: The Ultra implant can significantly improve hearing and speech abilities. No significant difference was observed in speech perception between the two arrays. Results confirmed that the Ultra implant is safe and effective for both paediatric and adult populations.

中国人群单侧人工耳蜗植入术后言语表现和听力的评价。

目的：在2022年完成了一项超人工耳蜗的现实世界研究，旨在比较术前和术后的表现。使用两种不同的电极阵列及其保留残余听力的能力也进行了研究。方法：本研究共纳入：78名受试者。所有参与者都完成了术前基线评估和术后语言和听力测试。对6岁以下的参与者进行主观问卷调查。还分析了阻抗和m电平随时间的发展。对于6岁以上的参与者，进行纯音听力学来评估听力保护。结果：术后平均辅助听力阈值和言语测试结果较术前有统计学意义的改善（p p > 0.05）。总体而言，阻抗和m水平呈典型的上升趋势。大多数参与者获得了良好的听力保存，而两个电极之间的听力退化无显著差异（p = 0.20）。结论：Ultra种植体能明显改善人的听力和语言能力。两组的语音感知无显著差异。结果证实，Ultra植入物对儿童和成人都是安全有效的。

期刊介绍： Cochlear Implants International was founded as an interdisciplinary, peer-reviewed journal in response to the growing number of publications in the field of cochlear implants. It was designed to meet a need to include scientific contributions from all the disciplines that are represented in cochlear implant teams: audiology, medicine and surgery, speech therapy and speech pathology, psychology, hearing therapy, radiology, pathology, engineering and acoustics, teaching, and communication. The aim was to found a truly interdisciplinary journal, representing the full breadth of the field of cochlear implantation.
