The size of the eustachian tube post-isthmic lumen in infants and children less than 2 years old is discussed. The material in our study consisted of serially sectioned eustachian tubes of twenty-six normal temporal bones and fourteen temporal bones harboring acute and secretory otitis media. The size of the eustachian tube lumen was measured with the aid of a millimetric grid mounted on a microscope. These measurements have shown that: There is no increase in the lumen size of the post-isthmic region of the eustachian tube from birth to 2 years of age. Each age group presents a considerable range in luminal area, compatible with the natural biologic distribution. No obstruction of the eustachian tube lumen was encountered in any of the pathologic specimens. There is no significant statistical difference between the lumen size of the post-isthmic region coming from normal temporal bones as compared with those from temporal bones with acute or secretory otitis media.
讨论了2岁以下婴幼儿咽鼓管峡部后管腔的大小。我们研究的材料包括26块正常颞骨和14块患有急性和分泌性中耳炎的颞骨的连续切片咽鼓管。借助安装在显微镜上的毫米网格测量咽鼓管腔的大小。这些测量结果表明：从出生到2岁，咽鼓管峡部后区域的管腔大小没有增加。每个年龄组的管腔面积都有相当大的范围，符合自然生物学分布。在任何病理标本中均未发现咽鼓管腔阻塞。来自正常颞骨的峡部后区域的管腔大小与患有急性或分泌性中耳炎的颞骨的管腔大小之间没有显著的统计学差异。
