1, facial asymmetry caused by congenital developmental problems

Asymmetric deformity of physiological development refers to the phenomenon that one side of the face is stunted during development, the other side is full, and the face is asymmetrical after adulthood. Because this type is hereditary, there is usually no need for plastic surgery. There are also some congenital diseases; For example, hemifacial short syndrome will lead to severe hypoplasia of one side of the face, accompanied by auricle deformity, which requires corresponding plastic surgery.

2. Traumatic facial asymmetry

If our face is hit by external force, severe trauma may lead to necrosis or scar formation of subcutaneous adipose tissue of facial skin. When we can't perform reduction treatment after facial fracture, facial asymmetry will be caused after wound healing.

3. Pathological facial asymmetry

There are many pathological reasons. For example, without plastic surgery after facial tumor resection, facial asymmetry may be caused by various tissue defects or organ displacement.

4. Facial asymmetry caused by behavioral habits

In addition to the above reasons, facial asymmetry is also closely related to the usual living habits. For example, if you chew food with only one tooth, the masseter muscles on this side of your face will be more developed, resulting in facial asymmetry. Life is far more than this example, just like breathing, mouth shape, and even bad standing and sleeping posture will affect your face shape.

Corrective measures:

Changing lifestyle or plastic surgery can help you solve this trouble. For example, people who like to sleep on the right side will have smaller cheeks on the right side than on the left.

If you change your posture from time to time, sometimes you sleep on the left and sometimes you sleep on the right, so that one side of your face will not be oppressed often. If you persist, you can improve the asymmetry of your face. However, self-correction is a difficult and long process. If the facial asymmetry is very obvious, it can be corrected by plastic surgery such as orthodontics and injection of face-lifting needles.

Extended data:

People's facial features become asymmetrical with age.

It is reported that the research mainly adopts three-dimensional digital imaging technology and root mean square deviation calculation. The researchers selected 19 1 volunteers aged from 4 months to 88 years and scanned their faces in detail. This digital imaging method can distinguish very subtle asymmetry.

Then, they calculate the root mean square deviation (RMSD) to quantify this asymmetry. Finally, it is concluded that the increase of age is positively related to the asymmetry of human facial structure. The facial structure deviates about 0.06 mm every ten years, and this deviation mainly occurs in the middle and lower part of the face, that is, from the eyebrows to the chin.

This change is very subtle, but its function can not be ignored, because the facial differences between people are mainly concentrated in the middle and lower parts of the face. This research has been published in the Journal of Plastic Surgery and Facial Plastic Surgery, or it will have a significant impact on related cosmetic projects.

In this regard, the researchers said that although some degree of facial asymmetry is considered attractive, achieving facial symmetry is the basic goal of plastic surgery. Therefore, "we hope to better understand how facial asymmetry evolves over time, thus promoting the improvement of cosmetic techniques such as facial remodeling."
