分泌性中耳炎(SOM)的发病机制还不十分清楚。一般认为咽鼓管阻塞、中耳负压导致血管内液体渗漏形成中耳积液。后来有学者发现咽鼓管阻塞并非是引起SOM的必要条件,而中耳积液中炎症递质和炎性细胞的发现,证实SOM是一炎症反应和渗出的结果。随着细胞因子的发现和研究不断发展,作
The pathogenesis of secretory otitis media (SOM) is not yet clear. Eustachian tube is generally considered obstruction, resulting in leakage of the middle ear caused by fluid leakage of the middle ear fluid. Later, some scholars found that eustachian tube obstruction is not a necessary condition for causing SOM, but the findings of inflammatory neurotransmitters and inflammatory cells in middle ear effusion confirmed SOM as a result of inflammatory reaction and exudation. As the discovery of cytokines and research continue to evolve, make
