The aim of this study was to examine how bimodal stimulation affects quality of life (QOL) during the postoperative period following cochlear implantation (CI). These data could potentially provide evidence to encourage more bimodal candidates to continue hearing aid (HA) use after CI.
In this prospective study, patients completed preoperative and 1-, 3-, and 6-month post-activation QOL surveys on listening effort, speech perception, sound quality/localization, and hearing handicap. Fifteen HA users who were candidates for contralateral CI completed the study (mean age 65.6 years).
Patients used both devices at a median rate of 97%, 97%, and 98% of the time at 1, 3, and 6 months, respectively. On average, patients' hearing handicap scores decreased by 16% at 1 month, 36% at 3 months, and 30% at 6 months. Patients' listening effort scores decreased by a mean of 10.8% at 1 month, 12.6% at 3 months, and 18.7% at 6 months. Localization significantly improved by 24.3% at 1 month and remained steady. There was no significant improvement in sound quality scores.
Bimodal listeners should expect QOL to improve, and listening effort and localization are generally optimized using CI and HA compared to CI alone. Some scores improved at earlier time points than others, suggesting bimodal auditory skills may develop at different rates.
本研究的目的是探讨双峰刺激如何影响人工耳蜗植入（CI）术后的生活质量（QOL）。这些数据可能为鼓励更多双峰刺激候选者在CI术后继续使用助听器（HA）提供证据。
在这项前瞻性研究中，患者完成了术前以及激活后1个月、3个月和6个月的QOL调查，内容包括听力努力程度、言语感知、声音质量/定位和听力障碍。15名对侧CI候选的HA使用者完成了该研究（平均年龄65.6岁）。
患者在1个月、3个月和6个月时分别以97%、97%和98%的中位率同时使用两种设备。平均而言，患者的听力障碍评分在1个月时下降了16%，3个月时下降了36%，6个月时下降了30%。患者的听力努力程度评分在1个月时平均下降了10.8%，3个月时下降了12.6%，6个月时下降了18.7%。定位在1个月时显著改善了24.3%，并保持稳定。声音质量评分没有显著改善。
双峰刺激使用者应预期生活质量会有所改善，与单独使用CI相比，使用CI和HA通常能优化听力努力程度和定位。一些评分在较早时间点比其他评分改善得更多，这表明双峰听觉技能可能以不同速度发展。
