语后聋患者人工耳蜗植入后听觉行为及言语可懂度分级的相关因素分析

目的：应用听觉行为分级（CAP）和言语可懂度分级（SIR）评估语后聋患者人工耳蜗植入后言语交流状况，探讨其得分与听力下降时间、植入时间、术前助听器使用情况的关系。方法：回顾分析23例语后聋人工耳蜗植入者的临床资料，收集其听力下降时间、植入时间、术前助听器使用情况等相关资料，应用CAP、SIR分级评估其言语交流状况。运用IBM SPSS Statistics19软件进行统计描述及结果分析。结果：CAP分级平均得分为6．13分，统计分析示CAP分级与听力下降时间、植入时间、术前助听器使用时间无显著相关关系（均P〉0．05）。患者均为语后聋，其SIR分级的平均得分为4．91分。结论：语后聋患者人工耳蜗植入后CAP分级与听力下降时间、植入时间、术前助听器使用情况无相关性。这可能是由于CAP分级的精确性和细节上的欠缺或该研究样本量限制，未显示出其与3个变量之间的关系。SIR不适用于评估语后聋患者人工耳蜗植人后的言语状况。

Study of categories of auditory performance and speech intelligibility rating of post-lingual cochlear implantes

Objective：To evaluate the verbal communication skills of post-lingual cochlear implantees with categories of auditory performance（CAP）and speech intelligibility rating（SIR）,and to explore their relationships with the duration of hearing loss,the postoperative time and preoperative hearing aid usage.Method：A retrospective analysis was conducted on 23cases of post-lingual patients with cochlear implantation.CAP and SIR were applied in the evaluation of verbal communication skills.IBM SPSS Statistics 19was used in statistical analysis.Result：The average score of CAP was 6.13,and statistical analysis showed CAP score was not significantly correlated with the duration of hearing loss,the postoperative time or the time of wearing a hearing aid preoperatively.The average SIR score of all these post-lingual patients was 4.91.Conclusion：It showed that CAP score was not significantly correlated with these three factors.This may due to the low accuracy of CAP or the small sample size in the present study.SIR was not suitable for the evaluation of post-lingual cochlear implantees.
