What causes congenital deafness in babies?

There is a lot of genetic factor, and during pregnancy the mother did not take reasonable care of herself, taking some drugs that are harmful to the health of the child. Causes hearing damage to the fetus. And due to improper operation during childbirth, it will also have a certain impact on the fetus.

If you don't eat some fresh fruits and vegetables reasonably before giving birth, the vitamin intake is relatively low. It can also lead to very poor physical development of the baby. Causes a series of diseases.

It is caused by genetics, genes, physically, blood, and psychiatric. And this situation is very serious, so when the baby has this situation, parents must take the baby to the hospital to do the corresponding **.

The baby's congenital deafness may be caused by genetic factors, or it may be that the pregnant mother has been in a noisy environment during pregnancy, so the baby will have congenital deafness.

Caused by genetic factors, drug poisoning, disease damage, prenatal factors, and stunted growth.

Congenital deafness in children may be caused by genetic factors or non-genetic factors.

1. Hereditary factors. If the deafness gene of the parent is passed on to the offspring, or if the gene is mutated during the development of the embryo, it may cause abnormal development of the eardrum or metabolic disorders, which can lead to the occurrence of hearing impairment. In addition, malformations of the outer and middle ears can lead to conductive hearing loss, while hypoplasia of the inner ear can lead to sensorineural hearing loss.

It should be noted that congenital inherited deafness may be inherited in an autosomal dominant manner, an autosomal recessive inheritance, or a companion hereditary deafness.

2. Non-hereditary factors. It may be related to the occurrence of infection, poisoning, trauma and other injuries during pregnancy or childbirth.

Congenital deafness is a condition in which the hearing organs are impaired or damaged due to various factors during the fetal period, and hearing impairment is pre-existing at birth. **The causes of congenital deafness can be divided into three categories: genetic factors, pregnancy factors, and childbirth factors.

Congenital deafness is a serious congenital condition, and the causes of the disease vary from some people to maternal illness or viral infections during pregnancy, or it can be caused by genetics. In response to the doubts of family members, we have invited experts to give you a detailed introduction to the causes of congenital deafness**, hoping to answer your confusion.

1.Hereditary factors.

Parents are born with deafness, and children are susceptible to this disease. But not all of the children born are deaf. Secondly, consanguineous marriage can also cause natural deafness. In addition, fetal ear tissue development malformations can also cause congenital deafness, but it can be corrected by surgery to restore hearing.

2.Drug intoxication.

During pregnancy, the expectant mother used harmful drugs, such as gentamicin, quinine and other ototoxic drugs, which can carry on the fetus's body through the placenta, resulting in fetal seventh cranial nerve poisoning and deafness. If the mother has been deeply anesthetized during pregnancy, it can also cause hearing damage to the fetus.

3.Disease damage.

If one parent has a sexually transmitted disease, such as gonorrhea and syphilis, it can induce congenital deafness. The mother suffers from rubella, toxoplasma gondii infection, etc., and the virus can cross the placenta and pose a threat to the fetus, causing malformations of inner ear development and deafness. Newborns weighing less than 1,500 grams at birth, suffering from hyperbilirubinemia, severe asphyxia during childbirth, and having purulent meningitis can cause deafness.

4.The process of childbirth.

When the mother is in labor, improper use of forceps can damage the child's hearing organs.

Congenital deafness will also have a special impact on the child's life, learning and future, so it is necessary to pay attention to it during pregnancy or childbirth to avoid adverse factors brought by the outside world. After a woman becomes pregnant, she should exercise more and get sick less, because getting sick will lead to a decrease in resistance and viral infection. Of course, getting sick is unavoidable, but don't just take medicine.

There are many causes of congenital deafness, such as: hereditary deafness, deafness caused by the mother's inappropriate medication during pregnancy, deafness caused by jaundice and other problems at birth.

Congenital deafness refers to a type of hearing impairment that occurs at birth or shortly after birth, which is caused by genetic factors or abnormalities during maternal pregnancy and childbirth, and can be divided into two categories: hereditary and non-hereditary. According to the type of pathology, it can be divided into conductive, sensorineural and mixed, and most of them are sensorineural deafness.

Genetic factors, which are carried in genes.

Drug factors: The mother's improper use of special drugs during pregnancy, such as aminoglycos, cytotoxic drugs, antimalarials and diuretics, etc., can enter the fetus through the placenta, resulting in fetal neurotoxicity and inducing deafness. In addition, deep anesthesia during pregnancy may also cause hearing loss to the fetus.

Disease damage, prenatal period, pregnant women suffer from certain infectious diseases during pregnancy, such as gonorrhea, syphilis, AIDS, etc., pathogens can involve the fetal auditory system through the placenta, damage the cochlea, vestibule, auditory nerve or cause viral or bacterial labyrinthitis, abnormal development of the inner ear, deformity resulting in deafness; Diseases such as premature birth, severe asphyxia at birth, low body weight, and purulent meningitis can damage the auditory nerve of the newborn and cause deafness.

During childbirth, improper use of forceps may cause trauma to the fetus's head and damage its auditory organs.

Hello, there are two main causes of congenital deafness, one is hereditary deafness: sensorineural deafness caused by genetic or chromosomal abnormalities. The second is non-hereditary deafness

In the first trimester of pregnancy, the mother suffers from viral infectious diseases such as rubella, mumps, and influenza, or systemic diseases such as syphilis, diabetes, nephritis, sepsis, and cretinism, or a large number of ototoxic drugs can make the fetus deaf. In addition, long labor during childbirth, dystocia, and fetal hypoxia due to birth trauma can also cause deafness.

Infectious factors: Maternal infections caused by various reasons during pregnancy, such as rubella virus, measles virus, influenza, toxoplasma infection, etc., can lead to poor development of the ear during the embryo and hearing impairment.

Pharmacological factors: high doses of ototoxic antibiotics during pregnancy, such as gentamicin, streptomycin, kanamycin, etc., can cause sensory deafness.

Abnormal labor: such as dystocia, prolonged delivery, birth trauma, etc., can lead to brain and ear damage, affecting hearing development.

Congenital malformations: congenital atresia of the external auditory canal, ossicular chain malformation, loss of tympanic membrane, cochlear dysplasia and other genetic factors: it is a hearing development disorder caused by genetic or chromosomal defects.

Patients with congenital deafness are mainly presented with varying degrees of hearing impairment at birth or shortly after birth, and most children are born unable to hear sounds

Congenital deafness, on the one hand, is due to the mother's cold during pregnancy, or the use of some ototoxic drugs, causing the child to be deaf after birth; There is also hereditary, parents or older generations have deafness. Twenty years ago, the medical system was not perfect, and hearing tests were generally not performed after a child was born, so it was difficult to tell if deafness was present at birth. Now, many large hospitals have done a better job in this regard, and the child will have a hearing test within three days of birth, and if there is a problem, the condition will be intervened as soon as possible.
