摘要
目的通过分析人工耳蜗植入术前听障儿童听觉稳态诱发反应（ASSR）与术后听觉能力的关系，旨在为预测人工耳蜗植入术后听觉能力提供客观依据。方法选取47例使用Nucleus C124型多导人工耳蜗系统的2～8岁语前聋儿童，收集受试患儿人工耳蜗植入术前的ASSR阈值，与患儿术后12个月有意义听觉整合量表（meaningful auditory integration scale，MAIS）得分比较，研究其相关性。结果47例患儿ASSR引出率为66．0％，其阈值与患儿术后1年MAIS得分呈负相关（相关系数r=-0．62），说明ASSR阈值越高，MAIS得分即听觉能力越低。结论虽然儿童人工耳蜗术后听觉能力受到多种因素影响，但根据ASSR测试结果可进行初步判断，为临床该预测提供了一定客观依据。
Objective To analyze the relationship between preoperative auditory steady-state responses （ASSR） and postoperative meaningful auditory integration scale （MAIS） scores and to provide objective evidences for predicting the auditory abilities of children after cochlear implantation （CI）. Methods Forty-seven prelingually hearing-impaired children of 2-8 years old with the Nucleus CI 24 multichannel cochlear implant system participated in this study.The preoperative ASSR thresholds and the MAIS scores of the patients 12 months after the cochlear implantation were obtained and their correlations were analyzed. Result The ASSR were successfully elicited in 31 of the 47 patients, with a percentage of 66%. There was a negative correlation between the ASSR thresholds before CI and the MAIS scores after CI （r=-0.62）, indicating that the higher the ASSR threshold, the lower the MAIS score or the auditory ability. Conclusion The auditory abilities of the children after cochlear implantation are influenced by several factors. ASSR results can be used as an objective parameter to preliminarily predict the postoperative auditory abilities.
