作者们以大量的颞骨标本对蜗导水管、圆窗膜、圆窗龛和面神经隐窝做了组织学的精确测量,并按年龄进行了分析。测量的方法是把颞骨标本固定,脱钙,并包埋于火棉胶中,做成20μ厚的切片,在连续切片中,每隔10张取一张用苏木精和曙红染色后镜下观察。除有病变的部位外均进行精确测量。结果如下:(1)549块颞骨测量了蜗导水管直径(取小管中部直径),平均值为197μ,其范围为40～600μ;一岁以下平 The authors used a large number of temporal bone specimens to histologically accurately measure the volute aqueduct, round window membrane, round window niche and facial nerve recess, and analyzed by age. The method of measurement is to fasten the temporal bone specimen, decalcify, and embed it in collodion to make a 20-μ-thick section. In a series of 10 slices, take a hematoxylin and eosin-stained micrograph Under observation. Except for the lesion site are all accurate measurements. The results are as follows: (1) 549 temporal bones were measured the diameter of the snail conduit (take the central diameter of the small tube), with an average of 197μ, the range of 40 ~ 600μ;
