患分泌性中耳炎(SOM)的小儿经腺样体切除后有效,故认为腺样体是中耳炎的一个因素。可能的机理有三:①引起咽鼓管的功能性阻塞;②促进咽鼓管逆流;③是致病菌的贮藏所。Collins等则提出另一可能原因认为腺样体释放有效炎性介质引起咽鼓管内局部炎症终致中耳渗出液。根据介质释放理论,对76例因腺样体肥大而切除的标本进行肥大细胞分布的对比研究。 Pediatric patients with secretory otitis media (SOM) are effective after adenoidectomy, so adenoids are considered a factor in otitis media. Possible mechanisms are three: ① cause functional blockage of the eustachian tube; ② promote reflux of the eustachian tube; ③ is the storage of pathogens. Collins et al. Suggest another possible reason for the adenoidal efflux of an effective inflammatory mediator that causes local inflammation in the eustachian tube to eventually cause effusion of the middle ear. According to the theory of media release, 76 mast cells were dissected from hypertrophy and adenoid resection.
