Introduction of augmentation rhinoplasty in Chongqing Emergency Center: The aesthetic part of the nose is located in the middle of the plane, accounting for 65,438+0/3 of the plane in the longitudinal direction. The width of the upper nose base is equal to the distance between the corners of the eyes in the transverse direction, and the connecting line between the lower nose point and the two pupils forms an equilateral triangle. A beautiful nose should have the following conditions: the size of the nose is in harmony with the five senses, the midline of the alar is not biased, the alar is symmetrical on both sides, the tip of the nose is round, the size is moderate, and the alar is hemispherical; Viewed from the side, the back line of the male nose is a straight line, while that of the female nose is a soft curve. The base of the nose is an equilateral triangle, and the nostrils are oval. Aesthetic index of nose: the ratio of the distance between alar points on both sides of nose index and the distance from nasal root point to lower nasal point is about 0.6 18. The included angle between the connecting line between the middle point of forehead and the lower point of nose and the line of nose bridge is 29 ~ 33. The included angle between the line between the center of the eyebrows and the root of the nose and the bridge of the nose is 130 ~ 140. The angle of the tip of the nose is the angle between the line of the nose and the columella, which is between 70 and 85. The nasolabial angle is the included angle between the columella and the midline of the upper lip, ranging from 80 to 95. Because of the important position of nose in facial aesthetics, and the flat face, flat nose and low nose bridge of Asians, it is easy to make people feel dull, with no outline and bright spots. Therefore, simple rhinoplasty can not make the aesthetic state of the nose perfect, and nasal plastic surgery should be comprehensive, three-dimensional and three-dimensional plastic surgery. Rhinoplasty is only suitable for patients with low nasal dorsum, and most patients have problems with their noses or alar, so today, with more attention paid to the perfect effect after plastic surgery, the number of patients with simple rhinoplasty is decreasing. Most patients gradually receive comprehensive rhinoplasty. Rhinoplasty materials Rhinoplasty materials can be divided into biological tissue materials and abiotic tissue materials according to their sources. Autologous cartilage is widely used as biological tissue material. Autologous cartilage has no possibility of rejection, but its material will leave scars on the body and may be absorbed and deformed after operation. Solid silica gel \ expanded polytetrafluoroethylene \ polyethylene is widely used as non-biological tissue materials, and there are also injections such as bone powder \ collagen \ sodium hyaluronate. Expanded PTFE \ Polyethylene is a molding model with micropores, but polyethylene is hard, and expanded PTFE is easy to deform, because both of them have micropores, so it is not easy to take out after surgery, and the tissue damage after taking out is great. Swelling also has the potential risk of long-term infection. Using solid silica gel prosthesis in today's treatment technology can effectively avoid some early complications, such as prosthesis exposure and skin redness. , and feel natural, easy to take out, is an ideal rhinoplasty material. The ideal tip of nasal tip plastic surgery should be upright and slightly tilted, not drooping. The nose should be round and full, of the right size, in harmony with the bridge of the nose and the five senses. In nasal surgery, many methods are usually used to reshape the nasal tip to achieve the ideal nasal tip effect. Thin nasal tip is generally shaped by autologous dermal flap, mostly gluteal groove dermal flap. The shape of nasal tip was natural after operation, and there was no scar at the donor site. Nasal tip hypertrophy generally adopts nasal tip reduction. It can reduce the hypertrophy of the nose, make the original inconspicuous tip stand out, and better improve the nose shape. The nose tip is low and flat, which makes the nose tip droop and lacks outline. Generally, autologous auricular cartilage or medpor is used to shape the nasal tip, and the effect of erect and slightly warped nasal tip after operation is ideal. Nose wing narrowing: the width of nose wing is equal to the distance between eyes and narrower than the width of lips. From the front, the columella and the nose should look like flying seagulls.
