本文通过对10例6～12个月胎儿和10只豚鼠圆窗膜的超微结构比较研究,进一步了解圆窗膜的正常组织形态学,生理作用和在某些中耳病理情况下对耳蜗功能影响机制的相关性。观察结果表明圆窗膜在某些条件下可以改变其细胞结合而具有渗透能力。因此在慢性化脓性中耳炎、耳内滴入毒性药物、外伤、肿瘤等病理情况下,皆可经圆窗膜引起内耳功能障碍。
In this paper, 10 cases of 6 ~ 12 months fetus and 10 Guinea pig circular window membrane ultrastructure study to further understand the round window membrane morphology, physiological function and in some cases of middle ear pathology of cochlear function Impact of the mechanism of relevance. Observations show that the round window membrane has the ability to change its cell binding under certain conditions. Therefore, in chronic suppurative otitis media, ear drops of toxic drugs, trauma, cancer and other pathological conditions, can be caused by the round window membrane inner ear dysfunction.
