摘　　要：目的观察人工耳蜗植入后植入耳残余听力的变化。方法对人工耳蜗植入术前能较好配合行为测听的58例听障儿童,人工耳蜗植入后利用游戏测听或纯音测听评估其术耳残余听力,58例术后随访3个月,43例术后随访1年,17例术后随访2年。结果与术前0.25-4kHz残余听力相比较,58例术耳术后3个月残余听力较术前明显下降(P<0.05),43例术后1年残余听力明显下降(P<0.05),但0.25-0.5kHz残余听力较术后3个月提高,差异有统计学意义(P<0.05);17例术后2年0.25-0.5kHz残余听力较术后3个月明显提高。结论人工耳蜗植入后可导致0.25-4kHz各频率残余听力下降,但术后1、2年时0.25、0.5kHz处的残余听力较术后3个月有所提高,1、2、4kHz残余听力无明显改变。Objective To investigate the effects of cochlear implantation on residual hearing and to evaluate the potential impact of long-term electrical stimulations on residual hearing. Methods 58 hearing impaired children with cochlear implants were included in this study. All subjects could cooperate with behavioral audiometry. Audiometric evaluations were carried out pre--implantation and 3, 12, 24 months post implantation respectively. Of 58 subjects, 43 were followed up more than 1 year and 17 were followed up more than 2 years. Results All 58 subjects showed significant differences （P^0.05） between pre and 3 months post--implantation of residual hearing at the individual frequencies of 0.25, 0. 5, 1, 2 and 4 kHz. 43 subjects followed up more than 1 year showed statistic differences （P〈0.05） between pre-and 3 months post--implantation, pre-- and 12 months post--implantation at 0.25, 0.5, 0, 2 and 4 kHz respectively. Comparing 3 months with 12 months post--implantation, there were statistic differences at 0.25 and 0.5 kHz, while no significant difference （P〉0.05） at 1, 2 and 4 kHz. Of 17 subjects followed up more than 2 years, there were significant differences （P〈0.05） between pre-- and various return visits post--implantation. Post--implantation return visits, there were significant differences between 3 months and 12, 24 months at 0.25 and 0.5 kHz respectively, not any significant differences on 1, 2 and 4 kHz. There were no sig nificant differences on each frequency between 12 months and 24 months post- implantation. Conclusion Residual hearing after cochlear implantation could decrease to some extent for various reasons. There were significant differences between 3 and 12 months post--implantation at 0.25 and 0.5 kHz. Not any significant differences were observed between 12 months and 24 months post--implantation at each frequency.
