中耳渗液咸以咽鼓管功能障碍为其主要病因,而对它与上呼吸道其他部位感染的关系重视不够,为此,作者们通过大量病例分两个阶段进行了分析研究。回顾性分析:1975～1976年有上呼吸道疾病的0～10岁患儿1,252例,其中有中耳渗液者467例,占37％,以4～10岁发病率最高。在上颌窦炎的471例中有中耳渗出者153例;腺样体肥大596例中有中耳渗出者157例(包括28例上述三种疾患同时存在者),另有157例存在中耳渗出 Middle ear effusion salty eustachian tube dysfunction as the main cause, but its relationship with other upper respiratory tract infection is not enough attention, therefore, the authors through a large number of cases were analyzed in two stages.

Among them, 467 cases were middle ear effusion, accounting for 37%, with the highest incidence at 4 to 10 years old. In 471 cases of maxillary sinusitis, there were 153 cases of middle ear exudation; in 596 cases of adenoid hypertrophy, 157 cases of middle ear exudate (including 28 cases of the above three diseases co-existed) and 157 cases Middle ear exudation
