中耳有粘液是一种常见的病理情况,Hilger曾指出,在治疗渗出性中耳炎时用通风管排除中耳负压,使粘液藉纤毛运动更易于排到咽鼓管,氏提议设计一个实验来证实把粘液推到咽鼓管就可在中耳产生负压的理论。本实验研究即为了证 Mucus is a common pathological condition in the middle ear. Hilger has pointed out that the use of ventilation tubes to exclude negative pressure in the middle ear in the treatment of exudative otitis media, so that mucus by ciliary movement more easily discharged to the Eustachian tube, the proposed design of an experiment To confirm the mucus pushed to the eustachian tube can produce negative pressure in the middle ear theory. The experimental study is to prove
