Chin plastic is also called chin plastic surgery in medicine, and chin plastic is mainly divided into two directions, one is lengthening and increasing, and the other is shortening and decreasing, which are two major directions. In common cases, such as chin protrusion, wedge osteotomy of chin should be done and retracted. This is a common surgical plan for chin plastic, and it is also the direction of mandibular retraction. Another method is local prosthesis or chin osteotomy to lengthen, raise and tilt the chin. Chin, that is, chin, is of great significance to facial beauty, because it is the lower court of the three facial courts and an important reference aesthetic index. The shortening, retraction and extension of the lower half can be directly reflected in the proportional relationship between the three chambers of the whole face and the proportional relationship between the prominent face, which has an important aesthetic effect. Therefore, the aesthetic effect of chin is very important, especially in facial aesthetics, which is often even more important than the common mandibular angle, that is, the effect of mandibular surgery. It can better adjust and improve the proportion of three facial cavities and highlight the relationship between face and face, that is, the so-called beauty line, such as the tip of the nose, which passes through the front of the lower lip and chin, can verify the aesthetic relationship between the whole middle face and the lower part. Therefore, the surgical effect of chin plastic is very remarkable. According to the specific situation and individual situation, choose different surgical schemes and specific and accurate personalized design to achieve the aesthetic effect you need.
