How is the external ear malformation caused

External ear malformation is a common congenital disease, which will affect the appearance and hearing of patients to varying degrees. So, how is the external ear malformation caused? Let's take a closer look.

Genetic factor

Genetic factors are one of the main causes of external ear malformation. If there are patients with external ear malformations in the family, the risk of their offspring will increase accordingly. Hereditary factors may lead to abnormal ear development, which may lead to external ear malformation.

Infection during pregnancy

Infection during pregnancy is also an important cause of external ear malformation. If a pregnant woman is infected with certain viruses or bacteria during pregnancy, such as rubella virus, cytomegalovirus, herpes simplex virus, etc., these viruses may be transmitted to the fetus through the placenta, affecting the development of the fetus' ears, thus causing external ear malformation.

Drug effects

If pregnant women take certain drugs during pregnancy, such as antiepileptic drugs, anticancer drugs, etc., these drugs may have adverse effects on the development of the fetus, resulting in external ear malformation.

environmental factor

Environmental factors may also lead to external ear malformations. If a pregnant woman is exposed to some harmful substances for a long time during pregnancy, such as radiation, chemicals, etc., these harmful substances may affect the development of the fetus' ear, resulting in external ear malformation.

Other factors

In addition to the above factors, there are other factors that may also lead to external ear malformation, such as abnormal fetal position in the uterus, fetal growth retardation, etc.

Treatment of external ear malformation

The treatment of external ear malformation mainly includes surgical treatment and non-surgical treatment. Surgical treatment is the main method to treat external ear malformation at present. It can improve the appearance and hearing of patients by reconstructing the shape and structure of the external ear. Non operative treatment mainly includes wearing hearing aids, using ear orthotics, etc. These methods can improve the hearing and appearance of patients to a certain extent.

How to prevent external ear malformation

Although the cause of external ear malformation is still unclear, we can reduce the incidence of external ear malformation through the following measures:

1. Avoid consanguineous marriage: consanguineous marriage will increase the incidence of genetic diseases, thus increasing the incidence of external ear malformations.

2. Health care during pregnancy: pregnant women should pay attention to diet and nutrition during pregnancy, avoid infection with viruses and bacteria, avoid taking drugs harmful to the fetus, and avoid long-term exposure to harmful substances.

3. Regular prenatal examination: pregnant women should conduct prenatal examination regularly during pregnancy to detect and deal with fetal abnormalities in a timely manner.

4. Avoid smoking and drinking: smoking and drinking will have adverse effects on the development of the fetus, thus increasing the incidence of external ear malformation.
