本研究的主要目的是确定是否有必要修订和/或扩展当前的听力学人工耳蜗植入体候选标准。研究设计是对22名成年人工耳蜗植入者的术后言语感知性能进行回顾性审查，这些植入者在最佳辅助条件下表现出术前辅音核辅音单词识别得分为30%或更高。选择该标准是为了超过Nucleus Freedom人工耳蜗植入系统北美临床试验规定的标准。22名患者的平均术前最佳辅助单音节词评分为41%正确。最佳术后条件（仅电或双峰）的术后受益程度范围为10 - 68个百分点，仅电条件的平均受益为27个百分点，双峰条件的平均受益为40个百分点。统计分析显示，非常显着差异术前辅助，植入，和双峰性能的辅音核辅音单音节词识别性能。也就是说，两种术后评分-仅电动和双模态-彼此之间以及与术前最佳辅助性能之间存在显著差异。目前的研究结果表明，大规模重新评估制造商和医疗保险术前听力候选人标准的成年人是必要的，让更多的听力受损的人利用人工耳蜗植入提供的好处。
The primary objective of this study was to determine whether a revision and/or expansion of current audiologic cochlear implant candidacy criteria is warranted. The study design was a retrospective review of postoperative speech perception performance for 22 adult cochlear implant recipients who demonstrated preoperative Consonant Nucleus Consonant word recognition scores of 30% or higher in the best-aided condition. This criterion was chosen to exceed that specified by the North American clinical trial of the Nucleus Freedom cochlear implant system. The mean preoperative best-aided monosyllabic word score for the 22 patients was 41% correct. The degree of postoperative benefit for the best postoperative condition (electric only or bimodal) ranged from 10 to 68 percentage points with a mean benefit of 27 percentage points for the electric-only condition and 40 percentage points for the bimodal condition. Statistical analyses revealed highly significant differences between preoperative-aided, implant-only, and bimodal performance on Consonant Nucleus Consonant monosyllabic word recognition performance. That is, both postoperative scores— electric only and bimodal—were significantly different from one another and from the preoperative best-aided performance. The current results suggest that a large-scale reassessment of manufacturer and Medicare preoperative audiologic candidacy criteria for adults is warranted to allow more hearing-impaired individuals to take advantage of the benefits offered by cochlear implantation.
