1, the principle of primary and secondary: before designing a face should find out the main and secondary problems, generally the main problem is often the effect of the biggest change, the secondary problem is the icing on the cake. To be able to distinguish the primary from the secondary will determine the order of the surgery, generally is to solve the major problems first and then solve the secondary problems, first bold and then refined, first solve the face problem and then solve the nose and eye problem. 2, the overall principle: the most taboo to do surgery only see the trees but not the forest, can not only look at the eyes or only look at the nose, must be the eyes and nose on the face as a whole to design. Beauty is about overall coordination and unity, rather than emphasizing a single beautiful, even if the eyes are very beautiful, nose is very beautiful, if not coordinated together on the face becomes a very twisted freak. 3, the principle of aesthetic standards: mastering aesthetic standards and aesthetic observation and its measurement methods is a plastic surgeon must. Although there are specific numerical standards in aesthetics, but we doctors often use the standards of proportion, such as the three chambers and five eyes, the tip of the nose – lip – jaw three points a line, nose forehead angle of 30 degrees, nasal small column and the upper lip at right angles and so on. 4, reversibility priority principle: the overall development trend of medical cosmetology is simple, safe and reversible, and now injectable cosmetology is hotly sought by many beauty seekers is a sign of this trend. Consultants in preoperative communication, should design as far as possible reversible treatment plan, can be injected as far as possible without surgery, so that both the beauty seeker and the hospital are beneficial, is a “win-win”. 5, personality principle: beauty is a standard, but not the only, the combination of external beauty and internal beauty to show a person’s personality. You are introverted, extroverted, or both inside and outside, the first thing to express from the outside, especially for people in the show business, you are taking the lively and lovely route, or take the sexy and mature route, in short, you have to have their own personality, to have their own want (to) express things. Personality is different, the design of the style is also different, I have not seen which doctor said so far, but this must be the future trend of plastic surgery development. 6, luck plastic surgery: modern people do plastic surgery mainly for the pursuit of perfection, improve the image, increase self-confidence, but there are also some people are for luck. Facial science in China has a history of thousands of years, such as “high nose, official luck” “nose is rich, collapsed nose is not wealthy, wide nose is not wealthy” said, the nose is required to pay attention to high and straight, nose full, nose meat, so that the man’s official fortune is good, and Women are rich, very prosperous husband phase. In fact, the ancient facial science and modern aesthetics also have a lot of conflict, for example, the ancient double jaw as a blessing, while this blessing in the eyes of modern people do not look young. “The pursuit of beauty is a symbol of social progress”, consultants and plastic surgeons, as messengers of beauty, not only need to be versatile and need to constantly learn innovative techniques, but also have the aesthetics to keep up with the times to be considered perfect.
