A study of Eustachian tube measurements in infants and children is presented. The study included 33 Eustachian tubes from normal temporal bones and 10 Eustachian tubes from temporal bones harbouring acute otitis media. The temporal bones underwent histologic serial sectioning. The lumen of the Eustachian tube's first portion, i.e. the pharyngeal part, was measured with the aid of a grid mounted on a microscope. These measurements show: A. The Eustachian tube lumen grows and enlarges to a small extent with age. B. Each age group presents a considerable variation in the range of area of the lumen comparable with the natural biological distribution. C. No statistical difference was found between the size of the pharyngeal portion of the lumen of the Eustachian tube from temporal bones which had acute otitis media and those coming from non-pathological ears. This comparison took into consideration age and physiological distribution. These findings are similar to our earlier findings regarding the isthmic region.
本文呈现了一项关于婴幼儿咽鼓管测量的研究。该研究纳入了来自正常颞骨的33根咽鼓管及来自患有急性中耳炎颞骨的10根咽鼓管。对这些颞骨进行了组织学连续切片。借助安装在显微镜上的网格测量咽鼓管第一部分即咽部的管腔。这些测量结果显示：A. 咽鼓管管腔随年龄增长而有一定程度的生长和扩大。B. 与自然生物学分布类似，每个年龄组管腔面积范围存在相当大的差异。C. 患有急性中耳炎颞骨的咽鼓管咽部管腔大小与非病变耳朵的咽鼓管咽部管腔大小相比，未发现统计学差异。该比较考虑了年龄和生理分布。这些发现与我们之前关于峡部区域的发现相似。
