上文的研究表明,急性和分泌性中耳炎的咽鼓管峡部和正常耳的相同。本文是研究咽鼓管的咽部情况以进一步评定“咽鼓管狭窄”能导致中耳炎或中耳萎陷的假说。作者用33例无中耳炎病史和10例曾患急性中耳经婴儿的带有咽鼓管的颞骨,按年龄(最大为3岁)分组;将咽鼓管分为下述五个特殊区域,在镜下观察测量,方法同上文。 The above study shows that the eustachian tube isthmus of acute and secretory otitis media is the same as the normal ear. This article examines the condition of the eustachian tube to further assess the hypothesis that “Eustachian tube stenosis” can lead to otitis media or middle ear collapse. The authors grouped by age (up to 3 years) 33 patients with no history of otitis media and 10 patients with eustachian tubes who had acute middle ear sores; the eustachian tube was divided into five special areas Microscopic observation and measurement methods the same way.
