摘要

目的分析语前聋患儿一侧人工耳蜗植入(cochlear implant,CI)对侧佩戴助听器模式下的聆听效果,以及非植入耳残余听力对聆听效果的影响。方法选取一侧人工耳蜗植入对侧佩戴助听器的语前聋患儿18例,分别测试其在单侧人工耳蜗植入、一侧人工耳蜗植入对侧佩戴助听器的双耳聆听模式(bimodal fitting,BIM)安静环境及稳态噪声环境下标准中文短句、双音节词、单音节词的识别率。结果安静状态下本组患儿CI、BIM模式单音节词言语识别率分别为82.67%±12.23%、83.61%±12.22%,双音节词分别为76.00%±16.13%、78.11%±14.84%,标准中文短句分别为60.11%±17.18%、65.43%±16.76%;信噪比10dB环境下CI、BIM助听模式患儿单音节词识别率分别为75.50%±14.12%、76.83%±14.15%,双音节词分别为68.22%±17.15%、77.18%±16.83%,标准中文短句分别为49.39%±19.26%、56.33%±19.55%,除两种模式下单音节词外其余言语识别率差异均有统计学意义(P<0.05),且非植入耳250、500 Hz助听听阈与BIM模式言语识别率呈负相关。结论语前聋患儿双耳双模式聆听时有一定优势,这种优势可能主要来自低频残余听力。
