There are 20.57 million people with disabilities with hearing and language impairments on the mainland
Among them, up to 800,000 deaf children under the age of 7
About 30,000 deaf children are added every year
First, protect the ears, starting from childhood
The key period of auditory speech development is childhood; hearing impairment is likely to lead to impaired speech development in children; hearing impairment has an impact on the development of children's emotional, psychological, and social interaction abilities.
Regarding the ear, let's first understand 2 questions.
1. What is a Eustachian tube?
The pharynx refers to the nasopharynx, the drum refers to the tympanic chamber of the middle ear, and a tube from the nasopharynx to the middle ear tympanic chamber is called the Eustachian tube.
The Eustachian tube has an important meaning in our human body.
The first is mainly to balance the tympanic chamber of the middle ear with the pressure of the outside world, and at the same time can drain some of the secretions of our middle ear, while also preventing and anechoic.
2. What is the difference between the Eustachian tube in adults and children?
Children's Eustachian tubes are short and horizontal, and upper respiratory tract infections can easily pass through the Eustachian tubes to the middle ear cavity.
It is precisely because of this that if a child causes an upper respiratory tract infection due to a cold or other condition, the virus and the microorganisms that cause the etiology will easily enter the middle ear through the Eustachian tube, thus inducing otitis media.
One of the most important causes of hearing loss in children is purulent otitis media.
Therefore, to protect the ears, we must start from childhood. Only with a healthy pair of ears can you hear the most beautiful sound of all things in nature.
Second, how to prevent deafness in infancy and early childhood
1, genetic or congenital causes
1) The family medical history needs to confirm in advance whether there are family members with deafness or other ear diseases in the family, and if so, they can be checked and avoided during pregnancy screening.
2), pregnant infection mothers during pregnancy, may also cause baby deafness due to some infections, so we must pay attention to pregnancy protection to avoid infection, while family members also give more protection and care.
2, the acquired reason
1), ototoxic drugs parents for the use of ototoxic drugs must be strictly in accordance with the instructions, and cautious use; if there are "use of ototoxic drugs will respond" family members, then the child's genetic certainty is larger, so you can check the family medication history in advance and avoid it in advance.
2), otitis media Purulent otitis media: avoid letting the child lie flat or feed too much and too urgently when feeding; avoid ear digging caused by ear trauma; timely treatment of acute infectious diseases of upper respiratory tract infections (such as scarlet fever, measles, whooping cough, influenza, etc.); avoid swimming in unclean water.
Secretory otitis media: caused by adenoid hypertrophy, chronic sinusitis and chronic inflammation of the upper respiratory tract caused by poor Eustachian tube function or obstruction, adenoidal hypertrophy should be treated in time to eliminate the cause.
Third, how to observe the hearing of children at different stages
Newborn hearing screening is one of the important means of early detection of hearing abnormalities in newborns and infants; it is necessary to go to a designated screening institution to receive professional hearing screening services; the child should be unable to hear the sound at the age of speech, and the best time to learn the language will be missed.
Normal newborns require hearing screening by a professional within 48 to 72 hours of birth, and if the newborn is admitted to an intensive care unit after birth, it is important to have a professional hearing screening before discharge.
After the newborn screening is not passed, it is necessary to go to the designated hospital for re-screening and hearing diagnosis. If the re-screening still fails, parents need to go to the Hearing Diagnosis Center in time to conduct a professional and meticulous examination of the child, determine the extent of the injury, and receive the next rehabilitation treatment.
Screening Methods:
Their hearing is judged by observing the auditory reflex.
Audio instruments: optional wooden fish, dual audio tubes (intermediate frequency), whistle (high frequency) or tambourine (low frequency) and other audio toys.
Audiometry process: the test room should be quiet, the timing of the sound is best to choose in the subject is in a light sleep state, about 30 cm from the test ear, suddenly give sound (more than 60dB), normal hearing subjects about 2.5 seconds within the auditory reflex.
Types of auditory reflex manifestations:
Sudden inflexion of the arms inwards, that is, the startle reflex; sudden eyelid opening, for the awakening reflex; sudden crying, for the crying reflex; before the test, the subject's eyelids are open, and the sudden closure of the eyes when giving the sound is called the closed eye reflex; there are also suction reflexes, breathing reflexes, and so on. The most frequent occurrence is the startle reflex.
In addition, a child around one year old should already have a call-up reaction, that is, a response when being called a name. If parents find that the child does not show a name response at this time, it is recommended to take the child to the hospital for hearing screening again to determine whether there is a hearing problem.
Fourth, how to protect your child's ears on a daily basis
1, reduce unnecessary ear ear can be chewed and swallowed to the outside of the body, will not affect the hearing, parents do not need to give the child a special cleaning; improper operation, easy to cause greater damage to the child's ear; if it must be cleaned, it is recommended that parents take their children to the regular hospital, by a professional doctor to operate cleanup.
2, when watching TV or listening to music, control the volume when parents play TV programs or songs to children, pay attention to controlling the volume, do not make too much sound, and avoid damage to the child's ears, resulting in hearing loss.
3, to prevent washing the face, swimming when the ear into the water parents to wash the face of the child, or take the child to swim, to prevent water into the ear; if the ear has entered the water, to help the child drain the water.
4, blowing nose and washing the nose of the baby cold runny nose, parents do not pinch the two nostrils together, should first press one side of the baby's nostrils, let the baby slightly force outward blow out the nose of the opposite side of the nostrils, and then use the same method to blow the other side; if the baby needs to clean the nose, parents need to use the normal saline to clean the baby's nose in strict accordance with the instructions, to avoid wrong operation damage to the nose and affect the ears.
5. Seek medical treatment in time when you are uncomfortable If your child feels ear pain or discomfort, parents should immediately take their child to a regular hospital for medical treatment, follow the doctor's instructions when taking medicine, and do not eat more.
