Outer ear health care method

The external ear includes the pinna and external auditory meatus. The pinna is located on both sides of the head. The skin is thin, there are few subcutaneous tissues, and the blood vessels are superficial. In addition, the pinna belongs to the exposed part of the body, and it is easy to be injured or frostbite. Trauma can cause blood vessels to rupture and form a hematoma. Once the hematoma is formed, it is difficult to absorb itself. At the same time, the auricle cartilage has poor anti-infection ability, and once infected, it is easy to cause auricle deformity due to cartilage necrosis.
     In the cold, especially when exposed to cold air for too long, frostbite may occur, resulting in ischemia. If severe frostbite occurs, the auricle, especially the auricle edge, may appear dry necrosis and become auricle defect. Therefore, in the care of the outer ear, we must pay attention to prevent trauma and frostbite of the auricle. In cold weather, especially in outdoor activities or work, pay attention to prevent trauma and frostbite of the auricle. In cold weather, especially in outdoor activities or work, cotton or woolen earmuffs should be worn. For those who are afraid of cold and poor peripheral circulation, they should pay more attention to the warmth of the outer ear.
     If you have frostbite, you cannot return directly to the hot room immediately. Use a hot towel or hot water bottle to quickly warm up the area. Use a clean palm to gently massage the pinna. Avoid rubbing it vigorously to gradually raise the temperature to normal and prevent the pinna from necrosis. If frostbite has occurred, the frostbite ointment can be applied locally. If there is ulcer or necrosis, antibiotic drugs can be added to prevent infection. At the same time, the auricle is also the acupuncture site for ear acupuncture treatment. For some young people who love beauty and fashion, they often pierce the ear hole. During the operation process, it is necessary to pay attention to strict aseptic operation and strict disinfection. To prevent the occurrence of auricle periosteal inflammation.
     The most important thing in the health of external ear canal is to correct the bad habits of ear picking. It is a normal physiological phenomenon to have cerumen in the ear canal, which is formed by the normal secretion of the skin of the ear canal combined with dander. Generally, a small amount of crumbs can be expelled by the vibration and mandibular movement during exercise without special cleaning. However, many people have the bad habit of picking ears. They often like to use hairpins, matchsticks and other objects to dig the ears, which is easy to cause damage to the wall of the ear canal. May damage the tympanic membrane or ossicles, causing perforation of the tympanic membrane and affecting hearing.
     Especially in the elderly, the elasticity and toughness of the auricle are reduced, the cerumen gland secretion of the cartilage is increased, the fat in the ear canal is correspondingly reduced, the cerumen is easily concentrated and hardened, and the skin of the external ear canal is very thin. , It is easy to damage the bony external auditory meatus. The correct way is not to dig your ears at random. If the secretion is strong and the cerumen is embolized, go to a regular hospital and let the doctor remove it with a special tool. If the cerumen is hard, you can use the cerumen liquid to soak it first. And clear it again. If some people often feel itchy in their ears, they can use cotton dipped in 75% ethanol or 3% boric acid ethanol to rub it. Not only itching can also be sterilized, but do not stretch too far.
    In addition, in daily life, we sometimes encounter small insects such as mosquitoes, flies, and ants flying into or crawling into the ear canal. At this time, you can use a syringe to rinse the ear canal to flush out the small insects, or use wine/oil to drip into the ear to remove the small The insects were drowned and removed with instruments. At the same time, accidental injuries should be prevented, and children should be taught not to insert foreign objects such as beads, beans, and pits into the ear canal while playing. Avoid taking dirty water into your ears when bathing or playing. It is best to wear earplugs to prevent water from entering the ear canal when swimming. Once you can enter the water, you can jump your head on one leg several times. The water will automatically flow out, and then gently use clean medical cotton. Dry the ear canal.
