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”。

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。

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

炎反应导致粘肿，中耳分泌物增多，最终导致鼓穿孔。

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最终会与鼓。

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。

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，它就会到达您的耳或鼓。

" 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。

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。

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。
