目的：分析语前聋婴幼儿助听后听觉与言语能力发育的相关性，探讨不同耳聋程度、不同评估阶段其助听前后的言语能力发育随听觉能力发展变化的关系。方法以32例语前聋婴幼儿为研究对象，助听器选配年龄3～34个月，平均15．6个月，分为极重度耳聋组（16例）、重度耳聋组（11例）和中度耳聋组（5例），使用听觉行为分级（categories of auditory performance ，CAP）和言语可懂度分级（speech intelligibility rating ，SIR）问卷分别于助听前及助听后1、3、6、9、12个月时对患儿的听觉及言语发育能力进行评估，并进行线性相关与回归分析。结果极重度、重度及中度耳聋组CAP与SIR评估得分均存在线性相关，相关性由低到高依次为极重度耳聋组（R＝0．656）、重度耳聋组（R＝0．758）、中度耳聋组（R＝0．849）（均为 P＜0．05）。助听前后不同评估阶段CAP与SIR评估得分均存在线性相关，相关性由低到高依次为助听前（R＝0．559）、助听后1个月（R＝0．575）、助听后3个月（R＝0．726）、助听后6个月（R＝0．823）、助听后9个月（R＝0．838）、助听后12个月（R＝0．855）（均为 P＜0．05）。结论语前聋婴幼儿助听后听觉与言语能力发育密切相关，言语能力随听觉能力的提高而提高；耳聋程度越轻、助听器使用时间越长，助听后婴幼儿听觉与言语能力发育的相关性越高。

Objective The aim of this study is to analyze the relationship between the development of audito‐ry and speech in infants with hearing loss after hearing aid fitting and discuss the development of speech with the a‐bility of auditory in infants with different degree of hearing loss and different stage of evaluation after hearing aid fit‐ting .Methods A total of 32 infants (17 boys and 15 girls) with prelingual hearing loss participated in this study . The age at hearing aid fitting ranged from 3 to 34 months with a mean of 15 .6 months .According to their hearing level ,all infants in this study were divided into three groups :group of profound hearing loss(16) ,group of severe hearing loss(11) ,group of moderate hearing loss(5) .CAP and SIR were used to evaluate their abilities of auditory and speech at pre -fitting ,1 ,3 ,6 ,9 and 12 months after hearing aid fitting respectively .A linear and regression a‐nalysis was done in the statistic procedure .Results There was a significant correlation between the scores of CAP and SIR for the three groups respectively .The correlation from low to high followed by the group of profound hear‐ing loss (R=0 .656 ,P=0 .000<0 .05) ,group of severe hearing loss (R=0 .758 ,P=0 .000<0 .05) ,group of mod‐erate hearing loss (R=0 .849 ,P=0 .000<0 .05) .There was also a significant correlation between the scores of CAP and SIR for the different evaluating stages respectively .The correlation from low to high followed by pre -fitting (R=0 .559 ,P=0 .000<0 .05) ,1 month after hearing aid fitting (R=0 .575 ,P=0 .000<0 .05) ,3 months after hearing aid fitting (R=0 .726 ,P=0 .000<0 .05) ,6 months after hearing aid fitting (R=0 .823 ,P=0 .000<0 .05) , 9 months after hearing aid fitting (R=0 .838 ,P=0 .000<0 .05) ,12 months after hearing aid fitting (R=0 .855 ,P=0 .000<0 .05) .Conclusion The development of auditory ability is closely related to speech ability which increases with the improvement of auditory ability .The less the infants have the hearing loss and the longer the infants use the hearing aids ,the higher the auditory ability is related to speech ability in infants after hearing aid fitting .
