Cochlear implantation has been considered a viable option to restore hearing perception in adults with severe to profound postlingual hearing loss. 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). 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. 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. 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.
人工耳蜗植入已被视为恢复重度至极重度语后听力损失成人听力感知的可行选择。
分析双侧感音神经性听力损失成人在两个阶段的行为听力反应以及P300潜伏期和波幅测量结果，第一阶段是他们使用助听器时，第二阶段是人工耳蜗植入（CI）使用12个月后。探讨行为评估与电生理评估之间的关联，因为人们认为使用不同听力设备进行听觉处理的研究有助于未来人工耳蜗的调试和适配，特别是对于无法给出主观反馈的患者（如幼儿和患有多种残疾的个体）。
前瞻性对照研究（伦理批准号11489/2014）。评估了12名成人，7名男性和5名女性，年龄在22至76岁之间，他们在使用过助听器后接受了人工耳蜗植入手术。
分析表明，患者开始使用人工耳蜗后听力阈值有所改善。比较P300潜伏期测量数据，人工耳蜗植入后Cz和Fz处的P300波有所增加。关于波幅，Cz处的P300平均值下降，但Fz处增加。行为评估与电生理评估以及年龄、性别、听觉剥夺和使用的电子设备等变量之间无显著相关性。
人工耳蜗植入使用12个月后听力阈值有显著改善。人工耳蜗植入使用12个月后，Cz和Fz处P300的平均潜伏期值增加，而Cz处的平均波幅值下降，Fz处增加。
