What causes microtia

Microauricular malformation is a common congenital ear malformation, which not only affects the appearance of patients, but also may affect the hearing of patients. So, what is the cause of microtia? Let's take a closer look.

1、 Genetic factor

Genetic factors are one of the main causes of microtia. If there is a history of microtia in the family, the risk of microtia in offspring will increase accordingly. In addition, some gene mutations may also lead to microtia.

2、 Infection during pregnancy

If a pregnant woman is infected with certain viruses or bacteria during pregnancy, such as rubella virus, cytomegalovirus, herpes simplex virus, etc., it may lead to abnormal ear development of the fetus, resulting in microtia.

3、 Drug effects

If pregnant women take certain drugs during pregnancy, such as antiepileptic drugs, anticancer drugs, etc., it may affect the ear development of the fetus, resulting in the occurrence of microtia.

4、 Environmental factors

If a pregnant woman is exposed to certain chemicals, radioactive substances, etc. for a long time during pregnancy, it may affect the development of the fetus' ears, thus leading to the occurrence of microtia.

5、 Other factors

In addition to the above factors, there are other factors that may also lead to microtia, such as malnutrition and some diseases during pregnancy.

6、 Treatment of microtia

The treatment of microtia mainly includes surgical treatment and non-surgical treatment. Surgical treatment is the main method to treat microtia at present. It can improve the appearance and hearing of patients by reconstructing the shape and structure of the ear. Non operative treatment mainly includes wearing artificial ear and hearing aid, which can help patients improve their hearing and appearance.

7、 Prevention of microtia

The preventive measures for microtia mainly include the following:

1. Do a good job of pre pregnancy inspection, and timely discover and treat potential diseases.

2. Avoid contact with harmful substances, such as chemicals, radioactive substances, etc.

3. Pay attention to diet and nutrition to ensure the nutritional needs of pregnant women and fetuses.

4. Avoid infection, such as colds, rubella, etc.

5. Carry out prenatal examination regularly to find and deal with fetal abnormalities in a timely manner.

8、 Summary

Microtia is a common congenital ear malformation, which is related to genetic factors, pregnancy infection, drug effects, environmental factors and other factors. At present, the treatment of microtia mainly includes surgical treatment and non-surgical treatment. The preventive measures mainly include doing a good job of prenatal examination, avoiding exposure to harmful substances, paying attention to diet and nutrition, avoiding infection, and conducting prenatal examination regularly.
