How is the microtia caused

Microauricular malformation is a congenital developmental abnormality of the ear, which is mainly manifested in the size, shape, location or structure of the auricle. This deformity will not only affect the appearance of patients, but also may have some impact on hearing. So, how is the microtia caused? Let's take a closer look.

1、 Genetic factor

Genetic factors are one of the main causes of microtia. Studies have shown that microtia may be related to some gene mutations, which may affect the development of the ear and lead to the occurrence of auricle malformations. In addition, people with microtia in their families will have an increased risk of microtia in their offspring.

2、 Environmental factors

Environmental factors may also play a role in the occurrence of microtia. During the embryonic development, the mother may be exposed to some harmful substances, such as chemicals, radioactive substances, viruses, etc., which may affect the normal development of the embryo and lead to the occurrence of microtia. In addition, mothers suffering from certain diseases during pregnancy, such as diabetes, may also increase the risk of fetal microtia.

3、 Other factors

In addition to genetic and environmental factors, there are other factors that may be related to the occurrence of microtia. For example, malnutrition, hypoxia, infection, etc. during embryonic development may affect the development of the ear, leading to the occurrence of microtia. In addition, the use of certain drugs may also affect the development of the fetus, increasing the risk of microtia.

4、 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, which can reconstruct the shape and structure of auricle and improve the appearance and hearing function of patients. Non operative treatment mainly includes wearing artificial ear and hearing aid, which is suitable for patients with mild microtia or auxiliary treatment after surgical treatment.

5、 Prevention of microtia

Since the occurrence of microtia is related to genetic factors and environmental factors, the prevention of microtia needs to start from the following aspects:

1. Genetic counseling: It is recommended to conduct genetic counseling for people with microtia in their families to understand the genetic mode and risk of microtia, so as to take corresponding preventive measures.

2. Avoid harmful substances: During pregnancy, the mother should avoid contacting harmful substances such as chemicals, radioactive substances and viruses to reduce the risk of fetal malformation.

3. Pay attention to nutrition and health: During pregnancy, mothers should pay attention to balanced nutrition, maintain good living habits and health, and avoid infection and disease.

4. Regular antenatal examination: During pregnancy, the mother should conduct regular antenatal examination to find and deal with abnormalities of the fetus in a timely manner.

6、 Summary

Microauricular malformation is a congenital malformation of ear development, which is related to genetic factors, environmental factors and other factors. The treatment of microtia mainly includes surgical treatment and non-surgical treatment. To prevent the occurrence of microtia, we need to start with genetic counseling, avoiding harmful substances, paying attention to nutrition and health, and regular prenatal examination.
