作者利用动物模型研究慢性外淋巴瘘对耳蜗结构和功能的远期影响。应用听觉脑干诱发电位(ABR)阈值测定和扫描电镜(SEM)观察其形态学的改变,并探讨二者之间的关系。采用36只成年雄性豚鼠,随机分成4组。第一组20只豚鼠,经后进路达乳突泡,刺破圆窗, The authors used animal models to study the long-term effects of chronic lymphatic fistulae on the structure and function of the cochlea. The morphological changes were observed by auditory brainstem response (ABR) threshold and scanning electron microscopy (SEM), and the relationship between the two was explored. Thirty-six adult male guinea pigs were randomly divided into four groups. The first group of 20 guinea pigs, after the arrival of milk Breast Bubble, punctured round window,
