中耳炎颞骨咽鼓管峡部粘-软骨膜的组织病理学观察

目的：了解中耳炎性病咽鼓管峡部粘－软骨膜的影响。方法：用光镜对３２耳各型中耳炎颞骨（中耳炎组）与５０耳正常颞骨（正常组）标本连续切片的咽这峡部粘－软骨膜,中耳腔鼓岬粘骨组织病理学比较观察。结果：中耳炎组和正常组颞骨标本咽鼓管峡部均无病理性阻塞;中耳炎组峡部粘－软骨膜厚度测量和病理观察,未见有明显炎症改变,与正常组比较无明显差异;而其中耳腔粘骨膜均明显炎症病变。这种炎症截然不同反应的界限恰好在咽这的

Histopathologicly observational study of cartilage-mucosa on the eustachian tube isthmus of temporal bone with otitis media

Objective: To explore the influence of inflammatory pathology change of otitis media upon cartilage-mucosa at the eustachian tube isthmus (ETI). Method:The cartilage-mucosa at ETI and bone-mucosa on the tympanic promontory of 32 temporal bones with otitis media were observated histopathologiclly in comparsion with 50 normal temporal bones under light microscopy. Result:The eustachian tube isthmus in all the 32 temporal bone with otitis media and in 50 normal temporal bone were unblocked. The thick-measures and pathology observations of the cartilage-mucosa on ETI in the temporal bones with otitis media revealed there was no obviously inflammatory change and no significantly difference in comparsion with the normal control group. But there was obviously inflammatory pathologic change on the bone-mucosa of tympanic promomtory of temporal bone with otitis media. The demarcation line of completely different inflammatory reaction in middle ear cleft was exactly at the connective line between cartilage and bone of eustachian tube. Conclusion: With the specifically histologic structure, the cartilage-mucosa on eustachian tube is possessed of very strong function of natural defence for inflammatory desease, and it almost is impossible to lead to obstruction of eustachian tube by inflammatory influence upon the cartilage-mucosa.
