目的研究语前聋患儿植入人工耳蜗后听觉言语能力的发育情况及相关因素。方法34例接受人工耳蜗植入的极重度语前聋儿童手术时年龄为1岁2个月～5岁10个月，平均3岁2．15个月，按照植入手术时年龄分为幼龄组（A组，＜3岁，17例）、大龄组（B组，≥3岁，17例），在植入手术前和开机后3、6、12个月四个时间点采用有意义听觉整合量表（meaningful auditory integration scale ，MAIS）和婴幼儿有意义听觉整合量表（the infant-toddler meaningful auditory integration scale ，IT -MAIS）对患儿进行听觉能力评估。结果全体患儿植入人工耳蜗后量表总分及三组问题的得分均明显高于植入前，并且随着开机时间的延长其得分逐步上升（P＜0．05），其中评价患儿对声音感知能力的Q3～6在开机后的3个月内进展最为迅速。B组植入术前与听觉辅具有关的问题Q1～2和开机后3个月Q3～6得分高于A组（P＜0．05），其余各项得分两组间差异无统计学意义。总体上男性和女性患儿各项得分无差异（P＞0．05），A组女性患者术前Q1～2得分高于男性（P＜0．05），其余各时间点男女间得分差异无统计学意义（P＞0．05）。结论随着使用人工耳蜗时间的延长，人工耳蜗植入患儿总体听觉能力呈逐步上升的趋势，进步最快的时间为开机后的3个月内，这个阶段较大龄的患儿对声音的察觉能力优于婴幼儿患者，但随着植入时间的延长两组听觉能力的发育无差异；不同性别患儿植入人工耳蜗后的听觉发育无差异。

Objective To evaluate auditory and speech development longitudinally over the first year after co-chlear implantation in prelingual deaf pediatric cochlear implant (CI) recipients .Methods Meaningful auditory inte-gration scale (MAIS) and infant-toddler meaningful auditory integration scale (ITMAIS) were used to evaluate 34 prelingual deaf children between 14 month and 5 years and 10 month before CI and 3 ,6 ,and 12 months after im-plantation .The effects of genders ,age at implantation ,and duration of post -implantation time were evaluated .Re-sults Three MAIS scores were displayed :total ,detection ,and perception .Each score from all the subjects was significantly improved than that before cochlear implantation ,and still getting further better with CI use(P<0 .05) . There was no significant difference between scores of males and females (P>0 .05) .Conclusion After cochlear im-plantation ,a significant increase in auditory capability occurred ,especially in the first 3 months .The factor of gen-der was no influence on auditory development .These results provide preliminary validation of MAIS/IT -MAIS for evaluation of pre -lingual deaf pediatric CI recipients .
