渗出性中耳炎(以下简称渗中)在中耳积液后,鼓膜像变化很大。渗中的诊断除了问诊外,通过对鼓膜的仔细观察也可确诊。如果看到了鼓膜的液面水平线当然不难诊断,但有些积液的病例看不到水平线则要靠鼓膜的颜色、厚度、位置的变化(主要是内陷的程度)来判断。还要通过听力检查和鼓室压测量检查。作者复习了正常鼓膜像以后指出中耳病变时鼓膜变化基本有以下四点,即①颜色改变,②厚度改变,③位置改变(内陷或膨隆),④穿孔。而渗中的鼓膜变化除了不穿孔外,上述的①、②、③项往往单独出现或重
Exudative otitis media (hereinafter referred to as infiltration) in the middle ear effusion, the tympanic membrane image changes greatly. Permeation of the diagnosis in addition to consultation, through careful observation of the tympanum can also be confirmed. If you see the tympanic membrane level of course it is not difficult to diagnose the fluid level, but some cases do not see effusion depends on the level of the tympanic membrane color, thickness, location changes (mainly the degree of invagination) to judge. But also through the hearing test and tympanometry measurements. The author reviewed the normal tympanic membrane as the tympanic membrane pointed out later when the change of the tympanic membrane basically has the following four points, namely ① color change, ② thickness change, ③ position change (retraction or bulging), ④ perforation. The infiltration of the tympanic membrane changes in addition to non-perforation, the above ①, ②, ③ items often appear alone or heavy
