What can ear injury cause?
summary
What can ear injury cause? Last year, uncle should have an accident that caused ear injury, but fortunately the situation was not very serious, and because of the timely treatment, uncle's injury recovered very quickly. I believe many people are not very clear about how to deal with auricle trauma. Now I will share with you the process from injury to cure. I hope you will pay attention to it.
What can ear injury cause?
Most of the auricle is composed of elastic cartilage. The external cause is perichondrium and thin skin. The skin adheres closely to the subcutaneous tissue, and the blood flow is slow. Because of these structural characteristics, the external ear is vulnerable to cold injury, auricle trauma is prone to hematoma, and difficult to absorb, and the treatment is not appropriate. Infection and inflammation are not easy to control, and even the auricle will be deformed due to scar contraction. Ear laceration is also a common kind of trauma, some exposed cartilage. First of all, debridement, with physiological saline to repeatedly wash the wound in Luo, it will be combined, but also in the active anti-inflammatory cooperation, in order to make the wound growth recovery better, can do diaphoresis, promote blood circulation, general ring laceration a week can heal.
Most of the ear injuries are auricle lacerations, but some of them bite their ears during the fight and spit out after they are bitten off. If they can recover the bitten part of the auricle, first clean it, then soak it in normal saline for half an hour, and then sew it together. At the same time, a large number of antibiotics are needed to control the infection, but attention should be paid to the beginning of recovery, Due to the blood circulation, the sutured auricle tissue turns black. Sometimes it needs to wait for several times before slowly recovering.
The eardrum is a layer of meninges between the external auditory canal and the middle ear cavity, called the eardrum, also known as the tympanic membrane. It is an oval translucent film, as thin as a sheet of paper, about 0.1 mm, shaped like a concave outward pointed bucket. Although the tympanic membrane is as thin as paper, it is also divided into L cortex, fiber layer and drilling limit layer. A small part without fiber layer above is called relaxation part, and the rest is tension part.
matters needing attention
Traumatic perforation of eardrum is mostly caused by sudden change of air pressure, such as sharp explosion of pressure around, slapping in the face, not mastering the essentials when diving, etc. Most of the perforation sites are in the tension part (probably because the tension of tension part is high, it is easy to perforation under the pressure of air pressure). When checking, there are blood stains or bloody tympanic membrane near the perforation, or the injured line of the tympanic membrane can be seen. The perforation site is generally in the center of the tension part of the tympanic membrane, and some are at the edge of the tension part. The patient's conscious symptoms are ear training, poor hearing, sometimes accompanied by tinnitus. The hearing curve is conduction deafness, but there are also mixed deafness or nerve deafness due to nerve stimulation.
