对侧使用助听器对人工耳蜗植入儿童句子识别能力的影响

摘要

Objective To explore sentence recognition rate differences in hearing-impaired children who are in electroacoustic stimulation(cochlear implant in one ear and a hearing aid in the opposite, CI&HA) mode and electrostimulation(cochlear implant in one ear, CI) mode in quiet and noisy environment.Methods In quiet and noisy environment, sentence recognition rate was compared in CI&HA mode and CI mode in 12 cases of children with cochlear implants.Results Electrostimulation mode is significantly impacted by the contralateral hearing aid.The sentence recognition rate of CI&HA mode and CI mode is 77.7%±15.0% and 73.0%±17.2% respectively in quiet, 60.8%±24.5% and 54.8%±19.7% respectively in noisy.Conclusion The performances of hearing-impaired children using CI&HA mode are much better than those using CI mode in quiet and noisy environment.%目的：探讨安静环境和噪声环境下，人工耳蜗植入儿童在电声双模式(对侧使用助听器)和电模式(对侧不使用助听器)助听下的句子识别率差异。方法在安静环境和噪声环境中，分别对12例人工耳蜗植入儿童进行句子识别率测试，比较两种助听模式之间的识别率差异。结果在安静环境中，电声双模式助听的人工耳蜗植入儿童句子识别率为77.7%±15.0%，电模式助听下的句子识别率为73.0%±17.2%，两者之间差异显著(P<0.05)；在噪声环境中，电声双模式助听下的句子识别率为60.8%±24.5%，电模式助听下的句子识别率为54.8%±19.7%，两者之间差异显著(P<0.05)。结论在安静环境和噪声环境中，电声双模式助听的句子识别率均高于电模式助听的句子识别率。
