人工耳蜗植入者对侧耳佩戴助听器的效果评价

目的　探讨人工耳蜗植入者对侧耳佩戴助听器的意义和作用。方法　对 6例年龄 7～ 18岁的语前聋患者于术后开机半年时在不同助听方式下 (人工耳蜗 +助听器和单独使用人工耳蜗 )进行声场 (啭音 )测听、言语功能评估和问卷调查 ,将结果进行统计分析。结果　人工耳蜗 +助听器较单独使用人工耳蜗声场 (啭音 )测试的各频率听阈低 (P <0 .0 1)。词汇识别测试显示两者均有良好的聆听效果 (P >0 .0 5 )。问卷调查显示患者普遍接受人工耳蜗 +助听器的方式 ,感觉舒适、方向性立体感强 ,交流更佳。结论　使用人工耳蜗者对侧耳佩戴助听器有助于更好地聆听。

Effect of Contralateral Hearing Aid for on Performance of Cochlear Implant User

Objective To investigate the effect of contralateral hearing aid on performance of cochlear implant user.Methods Free field measurement, Language-function evaluating and questionnaire were performed in 6 prelingual cochlear implant users (7-18 years old) in different conditions: with cochlear implant and contralateral hearing aid (CI-a),or cochlear implant only (CI).Those tests were performed at 6 months postoperation.Results The auditory threshold of CI-a was lower than that of CI in every test frequency ( P<0.05) .The hearing effect in words-identification test had no significant difference between two groups ( P >0.05).The questionaire showed that most cochlear implant users will choose contralateral hearing aid. With contralateral hearing aid the cochlear implant users could get better stereo felling, more comfortabale and more convenient communication.Conclusion Contralateral hearing aid for cochlear implant user can improve their hearing effect.
