A study of Eustachian tube measurement in infants and children is presented. The study comprised 53 Eustachian tubes from normal temporal bones and 17 Eustachian tubes from temporal bones harbouring acute and secretory otitis media. The temporal bones underwent histologic serial sectioning. The lumen of the Eustachian tube isthmus was measured with the aid of a grid mounted on a microscope. These measurements show: A) the Eustachian tube isthmus lumen does grow and enlarge slightly with age; B) each age group presents a considerable range in area, compatible with a natural biological distribution; C) no statistical difference was found in the size of isthmus lumens obtained from temporal bones which had been affected by acute or secretory otitis media, when compared with lumens of Eustachian tubes coming from non-pathological ears. This comparison took into consideration both age and physiological distribution.
本文介绍了一项关于婴幼儿咽鼓管测量的研究。该研究包括53根取自正常颞骨的咽鼓管和17根取自患有急性和分泌性中耳炎的颞骨的咽鼓管。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峡部的管腔。这些测量结果表明：A）咽鼓管峡部管腔确实会随着年龄增长而略有增大；B）每个年龄组的面积范围都相当大，符合自然生物分布；C）与取自非病变耳朵的咽鼓管管腔相比，取自患有急性或分泌性中耳炎的颞骨的峡部管腔大小在考虑年龄和生理分布的情况下没有统计学差异。
