分泌性中耳炎的发病机理,多年来,国内外学者进行了大量的研究工作,但意见仍有分歧。目前争论焦点,主要集中在分泌性中耳炎。究竟是因咽鼓管的阻塞,抑中耳腔的炎症引起?为了探索这个问题,本实验采用豚鼠耳泡(auditory bulla)的细菌培养,及细胞涂片,耳泡及咽鼓管的病理切片检查,了解某些中耳腔积液的发病机理(豚鼠的耳泡,相当于人的中耳腔)。我们应用银夹夹住咽鼓管的近咽口处,造成咽鼓管的机械性阻塞,应用烧红的铝丝烧灼咽鼓管腔,导致咽鼓管及耳泡的炎症感染。由于豚鼠非常娇嫩,情况稍有不
Secretory otitis media pathogenesis over the years, scholars at home and abroad conducted a lot of research work, but there are still differences of opinion. Currently the focus of controversy, mainly in secretory otitis media. What is the obstruction of the eustachian tube and the inflammation caused by the middle ear cavity? In order to explore this issue, we used bacterial culture of auditory bulla and pathological sections of cell smears, ear bubbles and eustachian tube Check to see some of the pathogenesis of middle ear effusion (guinea pig’s ear bubble, equivalent to the human middle ear cavity). We use the silver clip to clamp the eustachian tube proximal pharynx mouth, resulting in mechanical obstruction of the eustachian tube, the use of red hot aluminum wire burning eustachian tube cavity, causing inflammation of the eustachian tube and the ear bubble infection. As the guinea pigs are very delicate, the situation is slightly different
