目的：初步探讨术前助听器佩戴史对婴幼儿人工耳蜗植入（cochlear implant ，CI）者早期开放式言语识别的影响。方法植入年龄0．9～3．0岁的CI儿童306例，按照术前是否佩带助听器分为助听器（hearing aid ， HA）组94例，非助听器（non－hearing aid ，NHA）组212例，用普通话词汇相邻性测试（Mandarin lexical neighbor‐hood test ，M －LNT）分别对两组受试儿童进行开放式言语识别能力评估，比较两组儿童M －LNT 正确识别率。结果年龄相同或人工耳蜗使用时长相同的助听器组与非助听器组间M －LNT正确识别率的差异均无统计学意义（P＞0．05）；术前佩戴助听器不同时长者与非助听器组之间M －LNT 识别率差异无统计学意义（P＞0．05）。结论对于0．9～3．0岁行人工耳蜗植入术的重度和极重度听力损失儿童，术前有无助听器佩戴史对其术后开放式言语识别能力无显著影响。

Objective To explore the impact of pre-implant hearing aid fitting on the early open-set word recognition in children who received a cochlear implant(CI) when they were infants .Methods A total of 289 chil‐dren who received a cochlear implant between 0 .9 and 3 .0 years of age were included in this study .According to pre-implant hearing aid fitting ,participants were divided into hearing aid group and non-hearing aid group .The open-set word identification abilities of the cochlear implant children were evaluated via Mandarin Lexical Neighborhood test(M -LNT) .Results Comparisons of the scores of M -LNT between two groups displayed no significant differ‐ence at the same identification age or duration of CI use .Conclusion The abilities of the early open-set word rec‐ognition between hearing aid group and non-hearing aid group didn’t make significant differences for the CI chil‐dren w ho received a cochlear implant betw een 0 .9 and 3 .0 years old .
