Why have microtia

Microauricular malformation is a kind of congenital malformation of the ear, which is mainly manifested by abnormal shape, absence or incomplete development of the auricle. This disease not only affects the appearance of patients, but also may have some impact on hearing. So, why is there microtia? This article will discuss from many aspects.

Genetic factor

Genetic factors are one of the important causes of microtia. Studies have shown that microtia may be related to genetic factors such as gene mutation and chromosome abnormality. If there are patients with microtia in the family, the risk of their offspring may increase.

environmental factor

Environmental factors may also play a role in the occurrence of microtia. For example, the mother's exposure to certain chemicals, drugs, radiation, etc. during pregnancy may affect the ear development of the fetus, leading to the occurrence of microtia. In addition, pregnancy infection and malnutrition may also increase the risk of microtia.

Abnormal embryonic development

In the process of embryonic development, if the development of the ear is abnormal, it may also lead to microtia. For example, the cartilage, muscle, blood vessels and other tissues in the ear are poorly developed, which may affect the shape and function of the auricle.

Other factors

In addition to the above factors, there are other factors that may be related to the occurrence of microtia. For example, the abnormal position of the fetus in the uterus and oligohydramnios may affect the development of the ear. In addition, some congenital diseases, such as congenital, neural tube defects, may also be accompanied by microtia.

Treatment of microtia

For patients with microtia, the main treatment methods at present include surgical treatment and non-surgical treatment. Surgical treatment is the main method to treat microtia at present, which can reconstruct the shape and function of auricle. Non operative treatment mainly includes wearing artificial ear and using hearing aids, which can help patients improve their appearance and hearing.

How to prevent microtia

Although the specific cause of microtia is not yet clear, we can take some measures to reduce the risk of its occurrence. For example, during pregnancy, mothers should pay attention to maintaining good living habits, avoiding contact with harmful substances, strengthening nutrition, and preventing infection. In addition, regular prenatal examination, timely detection and treatment of fetal abnormalities, can also effectively prevent the occurrence of microtia.

epilogue

Microauricular malformation is a common congenital malformation of the ear, which is related to genetic factors, environmental factors, embryonic abnormalities and other factors. For patients with microtia, timely treatment can help them improve their appearance and hearing, and improve their quality of life. At the same time, we should also strengthen the prevention of microtia to reduce the risk of its occurrence.
