What injury does perforation of eardrum belong to

summary

After the appearance of eardrum perforation, there will be otodynia, fluid outflow, and even a small amount of bleeding in the external auditory canal. Let's see what kind of injury the perforation of eardrum belongs to.

What injury does perforation of eardrum belong to

First of all: perforation of eardrum is a slight injury. The tympanic membrane, also known as the eardrum, is an oval translucent membrane, which is composed of epithelial layer, fibrous layer and mucosal layer. It is located at the junction of the middle ear tympanic chamber and the external auditory canal, and forms the lateral wall of the tympanic chamber. It separates the external auditory canal from the middle ear cavity, and blocks foreign bodies and bacteria that protect the external auditory canal from entering the middle ear cavity. In the process of auditory conduction, the structure of the tympanic membrane can increase the incoming sound waves It compensates for the attenuation of sound when it comes in.

Secondly, the systemic treatment of tympanic membrane perforation caused by acute otitis media should be treated with sufficient antibiotics as soon as possible to control the infection. Penicillin, cephalosporin and other drugs can be selected. ② Local treatment: first use 3% hydrogen peroxide to clean the external auditory canal, and then use antibiotics to drip the ear fluid. If the inflammation is controlled, the perforation that can not heal by itself can be considered for surgical repair. ③ Etiological treatment: if there is a chronic disease, it needs to be treated according to the condition.

Finally: the tympanic membrane perforation caused by trauma should be removed. ② Avoid catching a cold. Do not blow your nose hard. ③ The external auditory canal should not be irrigated or medicated, and the larger or non self healing perforation should be repaired by surgery.

matters needing attention

Do not flush the external auditory canal with water, and do not use any medicine to drop the ear, because it is not beneficial. On the contrary, it can make bacteria enter the middle ear and cause infection. Patients usually should pay attention to avoid water for the ear canal, in the bath when you can use a tampon to plug the ear.
