? Everyone will have earwax. How is earwax formed? Does earwax need to be removed manually? When & ldquo; Earwax & rdquo; When it accumulates more, it will itch. Conditioned reflex, people will take it out, and it’s very cool. Pulling out your ears seems very simple. Everyone can do it, but I don’t know whether the method is right or not. Let’s take a look at those things about earwax.
The formation of earwax
the skin of the 1 / 3 cartilage segment outside the external auditory canal is different from the skin of other parts of our body. There is a sweat gland called cerumen gland, which is similar to the sebaceous gland of the skin and can secrete a kind of oil. The secretion just vomited from the cerumen gland is similar to wax in shape. It is mixed with the oil discharged from the sebaceous gland to form a very thin layer attached to the skin surface, which is the original earwax.
these earwax are twisted together with the dust and fallen skin debris in the ear canal. After drying, they become small pieces of light yellow loose flake earwax, that is, the earwax we see when we take out our ears. However, there is another kind of earwax that is wet, which is mainly caused by the strong secretion of cerumen gland and sebaceous gland in the ear. After the secretion is not dry, it accumulates in the outer eye and agglomerates into a mass. When pulling out the ear, it feels a little wet, commonly known as & ldquo; Oil lug & rdquo;.
Three functions of earwax
1. Resistance to bacteria and viruses
earwax is rich in oil and forms an acidic film on the surface of ear canal skin, giving the external ear canal the function of resistance to bacteria and viruses;
2. Prevent foreign bodies from invading the ear
the oil contained in earwax can moisturize the fine hairs on the skin of the external auditory canal. These fluffy fine hairs and sticky earwax can block the dust particles blown in from the outside and prevent insects from entering the external auditory canal.
in addition, the earwax can prevent the invasion of dirty water and prevent possible infectious diseases such as otitis media and otitis media when the ears are not in the water.
3. Protect the tympanic membrane
earwax to narrow the cavity of the external auditory canal slightly, filter and buffer the incoming sound wave, so that the tympanic membrane will not be damaged by strong sound.
in addition, cerumen rich in oil can maintain a certain temperature and humidity in the external auditory canal to ensure that the tympanic membrane deep in the auditory canal will not dry, so as to make the tympanic membrane in the best movement state.
earwax is actually a defense line to protect ears. Subconsciously, most people regard it as human waste. In fact, the suggestion is not to pull out your ears often. Earwax slowly moves from the inner ear canal to the mouth of the ear canal and accumulates to a certain extent. Through the movement of the mandibular joint during chewing, it will continue to fall off and drain out of the ear. There is no need to worry about blocking the ear canal and affecting hearing. Healthy external auditory canal itself has self-cleaning function. If you blindly dig it out, it may damage local soft tissue, cause otitis externa and even tympanic membrane inflammation, and affect hearing.
in addition, frequent ear pulling may also cause abnormal secretion of earwax. For the hard cerumen formed after the earwax is wrapped by dust and scaling, it may affect the hearing when it is blocked in the external auditory canal. At this time, you should go to the otolaryngology department and ask the doctor to take it out with specific instruments. It is recommended not to take out the earwax with too strong hardness by yourself.
Four Misunderstandings of pulling out the ear
1
if the tympanic membrane is broken, you will be deaf
positive solution: cutting out the tympanic membrane will cause hearing loss
people’s understanding of the tympanic membrane is, Once the eardrum breaks, there is no hearing. In fact, this is not the case. Tympanic membrane damage is daily
note:
often take out the ears to be careful of papilloma
often taking out the ears is also easy to swell the cuticle of the external auditory canal skin and block the hair follicles, which is conducive to the growth of bacteria. The skin of the external auditory canal is damaged and chronically congested for a long time, but it is easy to stimulate the secretion of cerumen glands, & ldquo; Earwax & rdquo; More and more. Chronic stimulation of pulling out the ear for a long time may also induce papilloma of the external auditory canal. The incidence rate of external auditory canal papilloma has dropped significantly since the abolition of the hairdresser’s ear cutting method with our razor.
earwax is used to protect ears?
there are cerumen glands in the skin on the surface of the lateral cartilage of the human external auditory canal, which can secrete a yellowish viscous substance called cerumen, commonly known as & ldquo; Earwax & rdquo; Or & ldquo; Cicada & rdquo;, It’s like & ldquo; Sentry & rdquo; Guard the door of the external auditory canal. Some of these substances are thin when dried in air, and some are like viscous grease. Usually & ldquo; Hide & rdquo; In the external auditory canal, it can protect the skin of the external auditory canal and adhere to foreign substances (such as dust, small flying insects, etc.).
for the ear, earwax is actually the protective umbrella of the ear. It has been quietly protecting the ear, but you can’t see it ~
how to correctly pull out the ear
1. It’s best to use a cotton stick to gently rotate in the external auditory canal, and then the ear faces down, and the cerumen can come out by itself; Try not to pull out your ears with sharp objects such as nails and iron swabs.
2. Do not form the habit of ear digging and dig your ears frequently, generally once a week or so; However, there may be & ldquo; Oil ear & rdquo; People can be a little shorter and can master it according to their own situation.
