Sade认为渗出性中耳炎系中耳换气障碍引起,Gottsbalk报告大部分渗出性中耳炎可藉咽鼓管通气治愈。作者以往研究则表明渗出性中耳炎病变开始于上鼓室、渐累及鼓窦、乳突气房。含气腔为炎性渗出物闭塞。一部分渗出物虽可自咽鼓管排出,但大部分仍贮留含气腔中,导致中耳负压形成。为进一步证实,作者测定急、慢性渗出性中耳炎249耳的鼓室压曲线,患儿年龄4岁至11岁。结果157耳为B型,92耳为C型。再用咽鼓管导管通气,B型157耳中通气后鼓膜膨隆者137耳,鼓膜无变化者20耳。通气后立即再
Sade believes that exudative otitis media is caused by the middle ear ventilation disorder, and Gottsbalk reports that most exudative otitis media can be cured by eustachian tube ventilation. Previous studies have shown that the exudative otitis media lesions began in the upper tympanic cavity, gradually and the sinuses, mastoid air room. Gas-filled cavity for inflammatory exudate occlusion. Although part of the exudate can be discharged from the eustachian tube, but most still retain the gas chamber, resulting in the formation of negative pressure in the middle ear. To further confirm the author of acute and chronic exudative otitis media 249 ears tympanic pressure curve, children aged 4 to 11 years old. Results 157 ears were type B and 92 ears were type C. Re-eustachian tube catheter ventilation, B-type 157 ears aeration after tympanic membrane bulging 137 ears, no change in the tympanic membrane 20 ears. Ventilation immediately after
