简介：目的评估语前聋人工耳蜗植入患者的听觉言语康复效果，分析康复效果的相关影响因素。方法采用听觉行为分级标准（categoriesofauditoryperformance，CAP）和言语可懂度分级标准（speechintelligibilityrating，SIR），对50例语前聋人工耳蜗植入患者术后1年的听觉能力和言语能力进行分级评估；分析CAP和SIR结果与植入年龄、性别、侧别、术前助听时间、术后配戴方式、耳蜗是否畸形、康复模式、性格、康复时间等9个因素的关系。结果植入年龄、术前助听时间、康复模式、性格、耳蜗畸形、康复时间对CAP有显著影响；植入年龄、术前助听时间、康复模式、康复时间、性格对SIR有显著影响；性别、术后配戴方式、侧别对CAP和SIR均无显著影响。结论术前及早进行听力补偿及康复训练，有利于术后听觉言语能力的提高；家庭参与及教养方式对患儿康复效果有很大影响。
