问题 单项选择题

窦口离窦底最高,炎症时脓液引流最不通畅的是()

A.额窦

B.蝶窦

C.上颌窦

D.筛窦前、中群

E.筛窦后群

答案

参考答案:D

解析:

上颌窦位于上颌骨内,开口于中鼻道,内衬覆的粘膜与鼻粘膜相延续,故鼻腔炎症时常引发上颌窦炎。上颌窦因开口位置较高,炎性分泌物不易排除而积聚于窦腔内,需要进行体位引流。筛窦后群开口于上鼻道,蝶窦开口于上鼻甲后上方的蝶筛隐窝,上颌窦、额窦和筛窦前、中群均开口于中鼻道。鼻旁窦炎症时,炎性分泌物经开口排出于相应的鼻道,因而了解鼻旁窦的开口,有助于临床诊断哪个鼻旁窦发炎。

All over my garden I’ve planted nothing but roses, because I especially love the flower.A close friend came for a visit the other day.I told her that she should pick a bunch of roses to beautify her bedroom.I promised that the smell of the roses would be wafted far, far away.

That girl friend of nine, walking into the garden in high spirits, smelt here and there, but in the end she didn’t pick a single rose.I said that she could pick many flowers; I told her that I was not a flower farmer and didn’t make a living out of them.Saying so, I raised the scissors for the sacrifice of the flowers, but she stopped me, crying no, no, no!

To cut such beautiful roses would hurt one, she said.With her hands seizing at my sleeves, she told me that by no means should they be cut.Roses are the smiling face of the earth, and who could be so iron-hearted as to destroy such a charming smile?

My mind was shocked: the ugly earth, the tough earth, the plain earth-it is for the reason of that smile that it wins the care and pity of people.
