Criteria of ideal nose shape: 1.Nose body in cone shape, the highest point is located in the tip of the nose; 2.Nose body in the middle, natural, beautiful and realistic shape; 3.Nose shape and face shape and other facial features in harmony and concord; 4.Stent is located under the nasal dorsal tendon, fixed more firmly. Common nose classification: low nose: to determine the height of the nose, we must consider it in conjunction with our own conditions such as the shape of the face. Each nationality has the average value of nasal bridge height, if from the root of the nose to the tip of the nose, the entire nasal bridge is relatively low, and below that value, it is called low nose. Saddle nose: a common nasal deformity in China, the height of the nose is lower than normal, the bone and cartilage part of the nose is mostly concave, but the tip of the nose is upward, shaped like a saddle. Straight nose: the height of the nasal bridge is still acceptable, but the shape is straight and lacks the sense of applied cone. Wave nose: There are two depressions on the nasal dorsal axis, making the nasal axis incomplete and smooth. Low-pitched nose: The tip of the nose is low-pitched and the highest point of the nose is located at the back of the nose. Low nasal root nose: low nasal root, nasal tip, nasal back shape is still possible, eye distance is wide, nasal body is short, disproportionate. Horizontal nostrils: The nasal end is poorly developed, resulting in the nostrils not being erected in the shape of “eight”, and the nasal wings are wide and flat, which is common in the secondary nasal deformity after cleft lip surgery. Rhinoplasty is the most common cosmetic surgery: the nose is elevated, reduced and shaped to improve its appearance and function. Rhinoplasty includes: rhinoplasty, hump nose correction, hawk nose correction, nasal wing defect repair, nasal tip cosmetic surgery, nasal column and nostril cosmetic surgery, nasal deformity repair after cleft lip surgery, nasal prosthesis removal, etc.
