The ear is the hearing organ in the five senses of the human body (the balance organ is also in the ear). It can feel all kinds of sounds in nature. Imagine how painful it is for a deaf-mute to face a silent world! At present, there are about 50 million deaf-mute disabled people in China, so it is necessary to popularize perinatal hearing health care knowledge, realize prenatal and postnatal care and improve the overall health quality of the people.
If you want to know how to protect your ears' hearing, you must first understand what causes deafness and what kinds of deafness there are.
According to the nature of deafness, it can be roughly divided into three types:
1, conductive deafness 2, sensorineural deafness 3, mixed deafness 1, conductive deafness
Deafness caused by congenital or acquired reasons in the process of sound transmission is called conductive deafness. Common diseases include: congenital malformation of external ear and ear, otitis media, ear trauma, cerumen embolism, otosclerosis and so on.
Second, sensorineural deafness
Due to congenital or acquired reasons, the inner ear is deformed or diseased, which leads to the nerve transmitting auditory signals to the auditory pathway of the brain, thus causing deafness caused by obstacles. Common diseases are: congenital inner ear malformation, drug-induced deafness, viral infection (mumps, etc. ), explosive deafness, noise deafness, sudden deafness, senile deafness, acoustic neuroma, etc. Among them, drug deafness is the most common. For example, the improper use of streptomycin leads to many deaf children.
Third, mixed deafness.
Its characteristic is that the above two kinds of deafness have their own characteristics. Common diseases are: otitis media for many years, without systematic treatment, which eventually leads to mixed deafness.
When you know the types of deafness and the causes of deafness, it is easy to understand how to protect your ears.
1. Babies born within 24 hours should be screened for hearing, and infants suspected of hearing impairment should be followed up regularly. Once deafness is diagnosed, early intervention can be carried out.
2. Try to avoid using ototoxic drugs. Such as streptomycin, gentamicin, kanamycin and chloramphenicol. If necessary, you should also closely observe the changes of hearing. Once tinnitus, squabble and other symptoms appear, you should stop taking the medicine immediately.
3. If the newborn finds that the external ear is deformed after birth, it should go to the otology department of a big hospital for expert consultation.
4. Children with respiratory infection can easily induce otitis media. Once you suffer from otitis media, you should go to the hospital in time to avoid sequelae.
5. There is cerumen embolism in the ear canal, which should be taken out by the doctor who transferred to the hospital.
6. Try not to use or use the Walkman as little as possible, especially if the volume is too high and the noise is very irritating. Long-term use will cause noise deafness.
7. Working in noisy environment for a long time (textile workshop, chainsaw and electric drill, etc.). ), pay attention to wearing protective earmuffs.
8. Stay away from or avoid setting off large fireworks and firecrackers.
9. Don't treat sudden tinnitus and deafness on one side lightly. You should go to the hospital immediately to ask an otologist to see a doctor, so as not to delay the best treatment opportunity and cause lifelong regret!
10. Senile deaf patients should go to a hospital with good conditions for examination, choose appropriate hearing AIDS, and improve their quality of life.
Human ears not only beautify the face, but also have very important physiological functions such as hearing and sense of position (balance). The ear is an auditory organ that receives sound stimulation, and the vestibule and semicircular canal of its inner ear are also balanced organs. The external ear (auricle external auditory canal) plays the role of sound collection, the middle ear (oval window of ossicular chain of tympanic membrane) plays the role of sound transmission, and the inner ear (auditory nerve endings of cochlea) plays the role of sound perception. Lesions in any part of the ear will affect hearing. Hearing function is of great significance for human beings to understand society and transform nature. Through language and voice, they can communicate with each other, exchange ideas, coordinate their work and live together. The auditory system also has the ability to distinguish loudness, tone and sound quality. A skilled worker and driver can judge the operation and failure of the machine by hearing. People can stand at attention, walk, run, ride a bike, dive, skate, and work high above the ground. In daily life, the inner ear balance function plays an important role. If there is a lesion in the vestibule, dizziness, nausea, vomiting and unstable standing may occur. Since the ear has such an important physiological function, we should pay attention to love and protection. How to protect your ears? I put forward the following points for readers' reference.
