Dr. Sundram said I have to wear those to prevent infections in my Eustachian tube.

Sundram医生说我得戴着以防 咽鼓管感染。

It can cause your eustachian tube, which is the pressure relieving tube inside the sinuses and your canal, to get inflamed, close up, 'cause it's a very short, not short, very narrow tube.

它会导致您的咽鼓管（鼻窦和耳道内的减压管）发炎、闭合，因为它非常短， 不是短，而是非常窄的管子。

M is for middle ear infection: DNS also predisposes to middle ear infection because Eustachian tube which is the only drainage source of middle ear, opens in nasopharynx and DNS can cause its obstruction and resulting in middle ear infections.

M 是中耳感染：DNS 患者更倾向于患中耳感染，咽鼓管是中耳唯一的引流源，在鼻咽部打开，DNS 可引起咽鼓管阻塞，导致中耳感染。
