The developmental changes of the ipsilateral and contralateral auditory brainstem responses (ABRs) were studied in 105 normal infants and children. In both ipsilateral and contralateral recordings, the peak and interpeak latencies shortened with increasing age, while the amplitudes of wave V had a tendency to become higher. Contralateral ABR amplitudes were always smaller than those of ipsilateral ABRs. In the contralateral recording, wave I was absent and the contralateral wave II and wave III complex began to separate after birth (25%); separation percentage reached 80-100% at 7 months of age. Our results suggest that the contralateral recording of ABRs is a useful measure of developmental changes in infant auditory pathways.
对105名正常婴幼儿的同侧和对侧听觉脑干反应（ABR）的发育变化进行了研究。在同侧和对侧记录中，波峰和峰间期潜伏期随年龄增长而缩短，而V波的波幅有升高的趋势。对侧ABR波幅总是小于同侧ABR波幅。在对侧记录中，出生后I波缺失，对侧II波和III波复合波开始分离（25%）；7个月龄时分离率达到80 - 100%。我们的结果表明，ABR的对侧记录是衡量婴幼儿听觉通路发育变化的一种有用方法。
