Structurally speaking, nasal plastic surgery is the result of poor development of nasal bone and cartilage, which is characterized by upturned nostrils. The whole nostril can be seen in the front view, and the angle between the tip of the nose and the alar of the upper lip and alar is too large in the side view. The ugly nose can be removed by treating the nose facing the sky, but it is difficult to treat the nose facing the sky, because the nose is short, the nostrils are exposed, and the skin and cartilage needed are not enough, which is very difficult to treat. It is necessary to extend the length of nasal septum cartilage when treating nose-up. In the operation, the nasal septum cartilage and alar cartilage were separated by open incision, and the nasal septum cartilage was lengthened with auricle cartilage or prosthesis. Autologous cartilage is used to prolong the nasal tip, and auricular skin cartilage composite tissue is used to make up for the defect of the upper edge of nostril, thus fundamentally correcting the overexposed nostril facing the sky. It is an effective way to correct and beautify the nose. Because the operation is difficult, it is necessary to choose regular medical beauty institutions and experienced doctors to do the operation, in order to have better surgical results.
