The significance of newborn hearing screening

The significance and objects of hearing screening in neonates

Hearing impairment (i.e. hearing loss or hearing impairment) is the most common physiological defect of human beings, and also one of the main causes of disability. There are 1.16 million deaf children in China, and the number increases at the rate of 20 to 40 thousand every year. The purpose of newborn hearing screening is to find the hearing impaired individuals as early as possible, so that they can get appropriate intervention before the critical age of language development, so that language development will not be damaged. Early detection of hearing impairment is the only important factor to prevent language development disorders in children with hearing impairment. Routine physical examination and parent recognition can hardly detect hearing impairment in the first year after birth, thus missing the best opportunity for treatment. Only newborn hearing screening is an effective method for early detection of hearing impairment. At present, it is believed that the etiology of auditory neuropathy is related to hypoxia, hyperbilirubinemia, oxygen free radicals and other factors. Therefore, brain stem evoked potential (BAEP) must be used in the hearing screening of high-risk newborns. Every child born in a hospital, hospital or health care center must be screened for hearing. If any problem is found, it is necessary to enter the diagnostic procedure in time. If the child’s hearing impairment is confirmed by the diagnosis procedure, help should be given within 6 months, which is very beneficial and important for improving the population quality and avoiding the appearance of deaf mute. Therefore, three days after birth, each newborn must be screened for otoacoustic emissions, and each high-risk newborn and / or those who fail to pass the otoacoustic emissions must be examined for auditory brainstem evoked potential.

Common sense of hearing disorders in children

Exudative otitis media is a common ear disease. The incidence of non suppurative otitis media, characterized by effusion and hearing loss in tympanum, is about 4% – 10%. The incidence of this disease is mostly related to the poor function of eustachian tube, infection and low immunity. Because of the atypical clinical symptoms, it is often difficult to find in the early stage. Before the disease, children have respiratory tract infections such as cold, rhinitis, sinusitis, etc. with the development of the disease, it gradually affects hearing. Children are often slow to respond to the voice, lack of concentration, and do not answer what they ask. They often turn on the volume a lot when watching TV, and their academic performance drops. Some children complain of earache and blockage in the ear Feeling, some children have tinnitus. With the development of science and technology, now we have the ability to screen exudative otitis media in the early stage, so that the disease can be found in the early stage, treated in the early stage, and the general prognosis is good. If the treatment is delayed, the adhesion of eardrum is formed, and the ossicular chain is fixed, causing irreversible hearing damage for life, which has a serious impact on children’s life-long learning and work. Otopharyngitis is usually the early stage of exudative otitis media, and its clinical manifestations are more atypical. It often occurs unconsciously after upper respiratory tract infection. If it is found in the early stage and treated in time, it will recover quickly. Otherwise, it will further develop and form exudative otitis media.

Early diagnosis in hospital is the key to find abnormal children

At an early stage, a parent found that their children’s development was not the same as that of their peers. They could not sit, climb or walk. But their parents didn’t pay attention to it. They thought it was just later than other children. Results only when the child can’t climb or walk for one year and nine months, can he go to see a doctor. Results after examination, it was found that the tension of adductor was high, and the patient could not crawl, stand on the tiptoe, and some deformation of spine. In this case, correction is more difficult.

If parents find their children are different from others in the early stage, they will go to the hospital for treatment. The situation of children is certainly not so serious as it is now, and it is much easier to correct it. However, due to the lack of knowledge of the parents of the children, they think that the children’s problems are just general underdevelopment, but they don’t know that there are many problems. And delayed the treatment of children, which may bring lifelong regret.

Some studies have shown that when children’s posture and movement disorders are found, early treatment and early rehabilitation treatment can achieve better therapeutic effect. This is because the brain tissue is in the period of the most vigorous growth and development in the early stage of infants. The brain has strong plasticity and compensation ability. If appropriate stimulation is given during this period, it is possible to tap the potential of the brain to promote the recovery of compensation. So the more early the training, the more likely the child is to return to normal. Remind parents here that when you find out that your child is abnormal, please take your child to the hospital as soon as possible, so as not to delay the best period of treatment and bring regret!
