The inflammatory response creates mucosal oedema and increase middle ear discharge, eventually leading to tympanic membrane perforation.

炎症反应导致粘水肿，中耳分泌物增多，导致鼓穿孔。

On Audiometric testing: 1) Otoscopy: Reddish hue on tympanic membrane called " schwartz sign" .

1）耳镜检查：鼓呈红色，称为“施瓦茨症”。

Its 3 parts are (1) auricle or pinna (2) external acoustic canal and (3) the tympanic membrane.

这 3 个部分分别是：（1）耳廓；（2）外耳道；（3）鼓。

Sound waves traveling down the auditory canal eventually collide with the tympanic membrane, which you probably know as the eardrum.

沿着听道传播的声波与鼓相撞。

The solution is the eardrum, or tympanic membrane, and the tiny bones of the middle ear.

解决方案是鼓或鼓，以及中耳的小骨头。

The tympanic cavity focuses the pressure of sound waves so that they're strong enough to move the fluid in the inner ear.

鼓腔集中声波的压力，这样它们就足够强大，可以移动内耳中的液体。

But once the sound wave passes through the ear canal, it reaches your eardrum, or tympanic membrane.

但是一旦声波通过耳道，它就到达您的耳或鼓。

" And then I'll probably wanna look in the ears, " kind of see how the tympanic membrane is looking.

“然后我可能想看看耳朵， ”看看鼓的样子。

External Acoustic (Auditory) Canal It extends from the bottom of the concha to the tympanic membrane and measures about 24 mm along its posterior wall.

外耳道从外耳门向内延伸至鼓，长度约 24 毫米。

Therefore, to see the tympanic membrane, the pinna has to be pulled upwards, backwards and laterally so as to bring the two parts in alignment.

为了看到鼓，耳廓必须向上、向后和横向拉，以便使两部分对齐。

Now, the middle ear, also called the tympanic cavity, is the relay station between the outer and inner ear. Its main job is to amplify those sound waves so that they're stronger when they enter the inner ear.

现在，中耳，也称为鼓室，是外耳和内耳之间的中继站。它的主要工作是放大这些声波，以便它们进入内耳时更强。
