The Eustachian tube function was studied in 11 children (3-9 years of age) with and without upper respiratory tract infection ( URTI ). During URTI the active muscular opening function deteriorated and middle ear pressure weakened, whereas the passive pressure opening and closing levels, reflecting tubal closing forces, increased. These findings may explain the high frequency of transient episodes of middle ear underpressure and middle ear effusion (MEE) in children. In children with a primary tubal hypofunction due to poor muscular opening function, URTI may contribute to recurrent or persistent MEE.
对11名3至9岁患有和未患过上呼吸道感染（URTI）的儿童的咽鼓管功能进行了研究。在上呼吸道感染期间，主动肌肉开放功能恶化，中耳压力减弱，而反映咽鼓管关闭力的被动压力开放和关闭水平增加。这些发现可能解释了儿童中耳负压和中耳积液（MEE）短暂发作的高频率。对于因肌肉开放功能差而原发性咽鼓管功能减退的儿童，上呼吸道感染可能导致复发性或持续性中耳积液。
