First, 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. However, some congenital diseases, such as hemifacial short syndrome, will lead to severe hypoplasia of one side of the face, accompanied by auricle deformity, which requires corresponding plastic surgery.

Second, 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.

Third, 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.

Extended data beauty research: human facial features become asymmetric with age

According to the British "Daily Mail" reported on June 65438+1October 3 1 Sunday, a recent study in auburn hills Hospital, Massachusetts, USA found that with the growth of age, people's facial structure will gradually deform, and every ten years, the five senses will deviate by about 0.06 mm.

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.
