The golden standard of facial plastic surgery is that the ratio of head height to face width is 1.6 18: 1. The human face is a highly symmetrical structure with the midline as the axis. Some landmark points of the midline include nasal root point, nasal tip point, inferior nasal point, upper lip point, lower lip point and submental point, which constitute the midline structure. The head can be divided into two equal parts by the horizontal line of the upper eyelid margin. The height of the face can be divided into three equal parts by the hairline, the brow, the root of the lower nose column and the horizontal line of the lower edge of the chin. The dividing line between the lower lip and the skin is located at the midpoint of the height below the surface 1/3, and the upper lip is at the height below the surface 1/3. The palpebral fissure inclines slightly upward, and the outer canthus is 2-3 mm higher than the inner canthus. The angular distance between the inner canthus is equal to the width of the left and right eyelid cleft. The nose width is slightly larger than the inner canthus spacing, which is 1/4 of the face width. The width of the cleft is 65438+ 0/3 of the width of the face. The distance from the posterior orbital margin to the ear is as long as that of the ear, which is 1/3 of the head height. The lower lip is located on the line between the tip of the nose and the chin, and the front edge of the upper lip is slightly narrowed to this line, or both. The gold standard of eye plastic surgery: a woman's eyes are the windows of the soul and the pen of inspiration. The distance between the two inner canthus should be 1/3 of the distance between the two outer canthus, the distance between the two outer canthus and the lateral edge of forehead should be 19-24 mm, and the distance between the upper eyelid edge and the eyebrow should be about 20 mm; The upper and lower diameters of ptosis 10- 12.5 mm, the left and right diameters of ptosis are 30-34 mm, and the corneal exposure rate is 80%. The gold standard of nose plastic surgery is "a flower on the face", which depends entirely on the nose. The length of the nose is 65438+ 0/3 of the length of the face, usually 4.5-5.5 cm. The outermost nostril does not exceed the vertical line of the inner canthus The distance between the lateral edges of the two nostrils is equivalent to 70% of the length of the nose, the width of the root of the nose is about 1 cm, and the tip of the nose is about 1.2 cm. The height of the nose is generally not less than 4.5 cm, and that of women is 4.3 cm; The ideal height of the tip of the nose is 65438+ 0/3 of the length of the nose, and 23mm for women. The nose below 22 mm is low; The normal shape of the tip of the nose is spherical, and the nostrils are oval and inclined to the tip of the nose, and both sides are symmetrical. Nose golden triangle nose frontal angle: size and position are very important to appearance, and 120 degrees-130 degrees is more appropriate. Nose and lip angle: 90 degrees is the most ideal angle. Angle of nasal tip: 85 -90 degrees is the most ideal angle. Golden aspect ratio: the width of the alar is wider, and the distance from the root of the alar to the tip of the nose is longer. The perfect ratio of the width to the length of the nose will be close to 0.7. The gold standard of lip plastic surgery Oriental women have small lips. Viewed from the side, it slightly protrudes from the lower lip and is slightly wider than the lower lip. The position of the squab is equivalent to the vertical line extending downward from the midpoint of the pupil when the eyes are looking up. The gold standard of oriental aesthetics, the data of human lips: the upper lip skin is 20-24.5 mm high, the middle lip skin is 13- 18 mm high, the upper lip is 5-8 mm high and the lower lip is 10- 12 mm high. There is a depression between the chin and the lower lip of chin plastic Jinbiao, which is the last low point of "four highs and three lows"; The transition between chin and cheek should be very smooth and gradual; The contact surface between chin and mandibular base should be as flat as possible, and there should be no double chin. The edge of the joint between the mandibular angle and the neck must be clear. Generally speaking, the bone feeling at the junction of chin and neck must be presented. A good forehead can fully reflect the beauty of health and wisdom. The forehead is flat, slightly protruding upward, and smoothly transitions to the nasal root. Its radian is graceful and smooth, and the nose-frontal angle formed is about 135, forming a soft and natural "S"-shaped curve from the forehead to the tip of the nose, which makes the appearance show ups and downs. The length from the forehead to the edge of hairline is the forehead. When the forehead turns to the zygomatic arch on both sides of the temple, it should be naturally plump. If the temple is sunken, the tortoise-shell corner on the face will be exposed, looking old and losing its youthful vitality. If the cheekbones are prominent and the face is rhombic, people feel stiff and not soft. At this time, the towering cheekbones can be cut off, and the face can restore the natural and full beauty. The gold standard eyebrow shape for eyebrow shaping consists of three parts: eyebrow, eyebrow peak and eyebrow tail. Eyebrows are closely related to eyes, and they are on the same vertical line with the inner edge of eyes and the outer edge of nose; The distance between the eyebrows is equal to the distance between the inner canthus and the width of an eye fissure; Eyebrow peak and external angle should be on the same vertical line; Eyebrows and outer corners of eyes, nose and lip bees should also be on the same diagonal. As far as eyebrows are concerned, the relationship between eyebrows, eyebrows and eyebrows is very important. Of course, other conditions are not excluded, such as the overall coordination of eye shape with face shape and nose shape. The gold standard of ear plastic surgery is mainly in auricle. Auricles are located on both sides of the head, which are symmetrical left and right. The auricle is about 6.5cm long and 3.5cm wide (the distance from the tragus to the tubercle of the helix), and the average depth of the concha is 65438±0.5cm. The auricle is divided into anterior, external, posterior and internal parts. The front outer surface is concave and the rear inner surface is convex. The position of auricle in skull is normal. Auricles are located on both sides of the skull. The upper end of auricle is level with the upper edge of eyebrow arch, and the lower end is level with the bottom of nose. The long axis of auricle is parallel to the line of nose bridge. The outer ear of a normal auricle forms a 90-degree angle with the outer ear. The included angle between the auricle and the lateral wall of the skull is called cranioauricular angle, which is about 30, and the concha is at right angles to each other. Seen from behind the ear, the external ear is also at right angles to the cranial lateral wall. The distance from the mastoid process to the edge of the helix is about 1.8cm. It is generally believed that the long axis of the auricle (the line between the highest point of 1/3 on the helix and the lowest point of the earlobe) is parallel to the bridge of the nose, but it is found that they are not parallel, and the angle of intersection between them is about 90. Attention! The golden ratio of plastic surgery is only the most perfect ratio. When we do plastic surgery, we must also do it according to our actual situation. Don't be blind!
