Ear is one of the important organs of the five senses, which not only controls hearing, but also has the function of maintaining body balance. Ear can be divided into auricle, external auditory canal, middle ear and inner ear. If any part of the ear is damaged, the result may be very serious and even lead to deafness, so we should take good care of our ears.
How to protect your ears?
Education should begin with children.
Many children often stuff small things into their ears. In these cases, parents should keep calm and take their children to see a doctor immediately.
Parents should teach their children not to stuff things into their ears, and don't try to dig foreign objects for their children, so as not to cause otitis externa or perforation of tympanic membrane.
2. Earwax washing is a kind of secretion that naturally protects the external auditory canal. No special cleaning is needed, just clean the auricle every day. Don't think that cotton swabs are better tools for ear plucking. In fact, it will only push most of the earwax deeper into the ear hole, forming a blockage, and the cotton ball may also stay in the ear canal.
When washing your hair or taking a bath, you can plug your ears with cotton balls to prevent sewage from flowing into the ear canal. Parents should pay attention to the fact that when the baby spits milk, the milk should not flow into the ear, causing otitis externa.
3. Noise environment
When people spend more than 40 hours a week in an environment of 85 to 90 decibels without taking protective measures; Or exposed to sudden loud noise, it will destroy the delicate cells of the cochlea and cause acoustic shock damage. Therefore, when there is danger of acoustic shock, such as industrial noise, especially in machine workshops or foundries, loud bells, gunshots and explosions, we should all wear special ear protectors. According to the Occupational Safety Ordinance, this protective device must be provided by the employer.
4. Drug use
When you find something wrong with your ears, you should see a doctor. Don't buy ear drops in the affected area yourself, so as not to aggravate the condition due to improper medication.
During pregnancy, women should follow the doctor's instructions because some drugs will affect the development of fetal hearing.
5. Early treatment
As the ear is an important organ, we should seek medical treatment as soon as possible under the following circumstances. For example:
Purulent discharge or bleeding
I feel pain because a foreign body has entered my ear.
L long-term earache
L sudden loss of hearing
Tinnitus and dizziness
Hearing care for children in Hong Kong
In Hong Kong, this service is provided by? The Department of Health and the Education Department provide services according to children's age, aiming at identifying children's abnormal hearing development as soon as possible, giving them appropriate treatment and counseling, and increasing their chances of recovery.
Newborn babies to children aged six.
Maternal and child health centers in all districts can receive hearing screening services free of charge. If the child is found to have abnormal hearing, he will be referred to the "Otolaryngology Specialist" or the "Children's Physical Fitness and Intelligence Testing Center" for comprehensive review and follow-up.
School health care
The Education Department will arrange hearing assessment for primary one students and refer them to the Otolaryngology Specialist for further treatment when necessary. The Special Education Section of the Education Department will also arrange for deaf children to attend suitable schools according to their hearing conditions.
Parents should also pay attention to their children's language development (such as inaccurate pronunciation), academic performance (such as not responding to teachers' questions) and daily habits (such as turning on the TV too loud or habitually using one ear). If in doubt, they can refer to an otolaryngologist for examination by a family doctor.
Love your ears and protect your hearing.
Editor's Note: According to the information provided by relevant departments, there are currently 20.57 million deaf people in China. Due to drugs, heredity, infection, diseases and other reasons, there are about 30,000 new deaf newborns every year. Hearing impairment seriously affects the life, study and social interaction of this group. March 3rd is National Ear Love Day, and a series of related essays are published in this issue. Let's pay close attention to this group, love our ears and protect our hearing.
Can deafness be prevented?
At present, the incidence of deafness in China lacks detailed epidemiological survey data. In the face of so many deaf patients, besides taking necessary medical and rehabilitation measures, it is the key to prevent deafness to actively carry out newborn hearing screening, popularize and publicize hearing health knowledge, attach importance to epidemiological investigation, carry out deafness publicity and consultation, strengthen medical supervision and scientific medication.
How to prevent fetal deafness?
Hearing care should begin during pregnancy. For example, before delivery, mothers should not receive preventive injections and their abdomen should not receive radioactive radiation to prevent their mothers from being infected by viruses. Once an infection occurs, it should be treated in time and ototoxic drugs should be banned. How to prevent deafness in neonatal period?
The prevention of neonatal deafness should start from the perinatal period, during which not only the organic auditory axis nervous system can be damaged, but also the inner ear hair cells can be damaged. Especially neonatal jaundice, in the process of premature labor induction, due to various reasons of trauma or hypoxia, it is easy to cause sensorineural deafness. Therefore, early prevention and timely treatment of these diseases is an important link in the prevention and treatment of deafness.
How to prevent childhood deafness?
Infectious deafness is a common and frequently-occurring disease in infants, among which conductive deafness caused by children's exudative otitis media and sensorineural deafness caused by diseases such as parotitis and high fever are the most common. Deafness in childhood is not easy to find in the early stage, especially in the infection period, and it is more likely to occur when oxybasic glycoside antibiotics are often used for treatment. Therefore, prevention of infection and scientific medication are important measures to prevent deafness.
hearing-aid
At present, hearing AIDS on the market are all volume amplifiers, which only focus on volume amplification, and are of little help to people who are completely deaf and extremely deaf. Cochlear implants are another option for them.
Deafness may be caused by inner ear trauma, disease or other reasons, resulting in hearing nerve damage, so that patients suddenly or gradually lose hearing.
Cochlear implant can bypass some damaged parts of the inner ear and directly stimulate the auditory nerve, so that patients can regain their hearing, which is impossible for ordinary hearing AIDS.
Cochlear implants help deaf people of all ages, including those who have been deaf for a long time and those who have been deaf in childhood. When deafness is so severe that hearing AIDS can't help, cochlear implant should be considered. Generally speaking, the shorter the hearing loss, the better. If the time is prolonged, it will increase the difficulty of postoperative training and reduce the postoperative effect.
Only professional doctors and audiologists can make appropriate suggestions on whether to implement cochlear implant. Related link 1998, some CPPCC members put forward the "Proposal on Suggesting the Establishment of Love Day Publicity Activities" at the first meeting of the Ninth National Committee of CPPCC. The Ministry of Health, the Ministry of Civil Affairs, the Ministry of Education, the State Family Planning Commission, the State Administration of Radio, Film and Television, the State Bureau of Quality and Technical Supervision, the State Administration of Pharmaceutical Products, the All-China Women's Federation, the China Association for the Aged, the China Disabled Persons' Federation, etc. 10 departments attach great importance to this. After careful investigation and demonstration, they unanimously agreed to designate March 3 every year as National Ear Love Day. (Liu Fu Series)
