| Sumario: | Specific correlations between the outcomes of cochlear implantation (CI) and hearing thresholds of the both ears in post-lingual asymmetric hearing loss (AHL) patients were not clear. To identify the variables influencing the outcome of CI in post-lingual AHL patients. We included 18 adult subjects who had CI in the worse ear due to post-lingual AHL with average hearing asymmetry of 36 dB. Speech perception scores were evaluated in the sound field with hearing aid on the better ear before CI, and with the cochlear implant in the worse ear at 3, 6, and 12 months after CI switch-on. Average increases in phonetically balanced word score, spondee word score, and everyday sentence score at 12 months from CI switch-on compared with those before CI were 38.9%p, 46.2%p, and 52.4%p, respectively. Multiple linear regression analysis showed that speech perception scores were negatively influenced by age at implantation and hearing threshold difference of both ears (HTD-Both) itself, rather than the worse or better ear hearing thresholds. Post-lingual AHL subjects with high average hearing asymmetry can benefit from CI in the worse ear, while CI outcomes can be adversely influenced by HTD-Both and age at implantation both in the short- and long-term follow-up 背景：语言后非对称性听力损失（AHL）患者的耳蜗植入（CI）的结果与双耳听力阈值之间的具体相关性尚不清楚。 目的：识别影响语言后AHL患者CI结果的不同因素。 方法：我们纳入了18位因语言后AHL而在较差的耳朵植入CI的成人受试者, 平均听力不对称度为36 dB。在CI植入之前置助听器于较好的耳朵上, 将耳蜗植入在较差的耳朵中的3个月、6个月和12个月时, 在声场中评估语音感知得分。 结果：与CI启用前相比, CI启用后12个月的语音平衡单词得分、长长格单词得分和日常句子得分的平均增加分别为38.9％p, 46.2％p和52.4％p。多元线性回归分析表明, 语音感知得分受植入时的年龄和两只耳朵本身的听力阈值差异（HTD-Both）的负面影响, 而不是受耳朵听觉阈值差或好的影响。 结论和意义：平均听觉不对称程度较高的语言后AHL受试者可从较差的耳朵中受益, 而短期和长期随访中, 植入后的双耳HTD和年龄都会对CI结果产生不利影响。 |
