Secretory otitis media, middle ear atelectasis, and retraction type cholesteatomas are the most frequently occurring chronic middle ear diseases; and eustachian tube obstruction and the generation of negative or less than atmospheric middle ear pressure is said to be an essential factor in the pathogenesis of these diseases. It has been found that habitual sniffing causes high degrees of negative middle ear pressure in diseased ears; this finding demonstrates eustachian tube patency rather than obstruction. Ears intubated for chronic secretory otitis media, middle ear atelectasis, and cholesteatoma were examined to identify patent eustachian tubes. More than one third of the patients aspirated a solution into the middle ear with one or more sniffs by aspirating air from their middle ears, demonstrating eustachian tube patency rather than obstruction.
分泌性中耳炎、中耳不张和内陷型胆脂瘤是最常见的慢性中耳疾病；咽鼓管阻塞以及中耳负压或低于大气压被认为是这些疾病发病机制中的一个重要因素。研究发现，习惯性吸气会导致患病耳朵出现高度的中耳负压；这一发现表明咽鼓管通畅而非阻塞。对因慢性分泌性中耳炎、中耳不张和胆脂瘤而插管的耳朵进行检查，以确定通畅的咽鼓管。超过三分之一的患者通过从中耳吸气，经一次或多次吸气将溶液吸入中耳，表明咽鼓管通畅而非阻塞。
