简介 人工耳蜗植入被认为是恢复患有严重至极重度舌后听力损失的成人听力感知的可行选择。目的 分析双侧感音神经性听力损失成人的行为听力反应以及 P300 潜伏期和振幅测量，首先是使用助听器 (HA) 时，然后是使用人工耳蜗 (CI) 12 个月后。我们探讨了行为和电生理学评估之间的关联，因为人们相信，使用不同助听器进行听觉处理的研究有助于未来的 CI 调整和验配，特别是对于无法提供主观反馈的患者（例如幼儿和患有多种残疾的个人）。方法 前瞻性比较研究（伦理批准 11489/2014）。对 12 名成年人进行了评估，其中 7 名男性和 5 名女性，年龄范围在 22 至 76 岁之间，他们在 HA 经历后接受了 CI 手术。结果 分析显示，当患者开始使用 CI 时，听力阈值有所改善。比较 P300 潜伏期测量数据，CI 后 Cz 和 Fz 处的 P300 波有所增加。关于振幅，P300平均值在Cz处减小，但在Fz处增大。行为和电生理评估与年龄、性别、听觉剥夺和使用的电子设备变量之间没有显着相关性。结论 经过 12 个月的 CI 体验后，听力阈值有了显着改善。使用 CI 12 个月后，P300 的平均潜伏期值在 Cz 和 Fz 处增加，而平均振幅值在 Cz 处减少，在 Fz 处增加。
Introduction Cochlear implantation has been considered a viable option to restore hearing perception in adults with severe to profound postlingual hearing loss. Objectives To analyze behavioral hearing responses and P300 latency and amplitude measurements in adults with bilateral sensorineural hearing loss at two phases, first when they were using hearing aids (HAs) and, then, after 12 months of cochlear implant (CI) use. The association between behavioral and electrophysiological evaluations was explored, as it is believed that the study of auditory processing with different hearing devices can contribute to future CI adjustments and fittings, especially for patients who cannot give subjective feedback (such as small children and individuals with multiple disabilities). Methods Prospective comparative study (Ethical approval 11489/2014). Twelve adults were assessed, 7 males and 5 females, in the 22 to 76 years old age range, who had undergone CI surgery after HA experience. Results The analyses showed an improvement of hearing thresholds when patients started using CIs. Comparing data from P300 latency measurements, there was an increase of the P300 wave post-CI at Cz and Fz. Regarding the amplitude, P300 mean values decreased at Cz, but increased at Fz. There was no significant correlation between behavioral and electrophysiological assessment and the variables age, gender, auditory deprivation, and electronic device used. Conclusion There was a significant improvement of hearing thresholds after twelve months of CI experience. The mean latency values of P300 after 12 months of CI use increased at Cz and Fz, while mean amplitude values decreased at Cz and increased at Fz.
