通过测量正常耳的乳突气房面积来确定乳突气房发育情况,同时测定在捏鼻吞咽(Toynbee法)后鼓室内最大的负压,分析了乳突气房面积与中耳负压间的关系。结果表明,二者呈负相关,乳突气房面积越小,所产生的鼓室负压值越大。讨论了乳突气房在中耳负压产生中所起的作用,阐明乳突气房发育对于中耳炎的发病具有重要意义。
The development of mastoid air space was determined by measuring the area of the mastoid air space in normal ears. The maximum negative pressure in the tympanic space after the Toynbee method was measured. The relationship between the area of the mastoid air space and the negative pressure in the middle ear Relationship. The results showed that the two were negatively correlated, the smaller the area of the mastoid air chamber, the greater the negative pressure generated by the tympanic cavity. Discuss the role of mastoid air chamber in the production of negative pressure in the middle ear and clarify that the development of mastoid air chamber is of great significance for the pathogenesis of otitis media.
