Retrospective chart review.
Tertiary referral center.
One hundred four (105 ears) postlingually deafened adults who scored ≥30% CNC word recognition in the ear to be implanted preoperatively.
One hundred four subjects underwent cochlear implantation.
Pre- and postoperative CNC word scores and AzBio sentences in quiet and noise in the ear to be implanted as well as the bilateral-aided condition pre-CI and at 1, 3, 6, and 12 months post-CI.
Statistically significant improvement was demonstrated for CNC and AzBio sentences in quiet and noise for the CI alone and bilateral listening conditions. Most improvement was demonstrated by 6-months postoperatively (p < 0.001) with the exception of AzBio sentences in noise demonstrating improvement within 3 months (p < 0.001). For patients with preop CNC scores up to 40% (n = 57), all recipients demonstrated either equivocal (n = 17) or statistically significant improvement (n = 40) for CNC word recognition in the CI-alone condition and none demonstrated a significant decrement in the bilateral condition. For patients with preop CNC scores >40% (n = 47, 48 ears), 89.3% (42 patients) demonstrated either equivocal (n = 24, 50%) or statistically significant improvement (n = 19, 39.6%) for CNC word recognition in the CI-only condition and none demonstrated a significant decrement in the bilateral condition.
CI candidates with preoperative CNC word scores higher than conventional CI recipients derive statistically significant benefit from cochlear implantation for both the CI ear and best-aided condition. These data provide further support for the expansion of adult CI candidacy up to at least 40% CNC word recognition preoperatively with consideration given to further expansion possibly up to 60%.
1）对术前 CNC 得分≥30%的成年人工耳蜗（CI）植入者的术后结果进行随访调查，2）描述这组表现较好的患者的术后表现轨迹。

三级转诊中心。
104 名（105 耳）后天失聪的成年人，术前植入耳 CNC 单词识别率≥30%。
104 名受试者接受了耳蜗植入。
植入耳术前和术后 CNC 单词得分和 AzBio 句子在安静和噪声中的得分，以及植入前和植入后 1、3、6 和 12 个月的双侧辅助条件下的 CNC 单词得分和 AzBio 句子在安静和噪声中的得分。
CI 单独和双侧听力条件下，CNC 和 AzBio 句子在安静和噪声中的得分均显示出统计学上的显著改善。大多数改善发生在术后 6 个月（p<0.001），除了噪声中的 AzBio 句子在 3 个月内改善（p<0.001）。对于术前 CNC 得分高达 40%的患者（n=57），所有接受者在 CI 单独条件下的 CNC 单词识别均表现出不确定（n=17）或统计学上的显著改善（n=40），而在双侧条件下则没有显著下降。对于术前 CNC 得分>40%的患者（n=47，48 耳），89.3%（42 名患者）在 CI 单独条件下的 CNC 单词识别中表现出不确定（n=24，50%）或统计学上的显著改善（n=19，39.6%），而在双侧条件下则没有显著下降。
术前 CNC 单词得分高于传统 CI 接受者的 CI 候选者从耳蜗植入中获得了统计学上的显著益处，无论是在 CI 耳还是最佳辅助条件下。这些数据进一步支持将成人 CI 候选者的术前 CNC 单词识别率扩大到至少 40%，并考虑进一步扩大到 60%。
