According to facial aesthetics standards, the front of the human face is divided into three equal parts (three chambers) from the frontal hairline to the bottom of the chin. If the length of the nose is less than 1/3 of the total length of the nose, it can be judged as short nose. Because of the short nasal deformity, there is a shortage of various and multi-level tissues such as skin, supporting structures and mucous membranes at the same time, its correction is more difficult. According to the gap between the nasal length and the ideal value, short nasal deformity can be divided into the following types: 1, mild short nasal deformity: the nasal length is less than the ideal value of 1-3mm, manifested as a low nasal tip, generally not accompanied by a low nasal root nasal dorsum; 2, moderate short nasal deformity: the nasal length is less than the ideal value of 3-5mm, the nasal height is less than 1/2 of the nasal length, accompanied by a low nasal root nasal dorsum; 3, severe short nasal deformity: the nasal length is less than the ideal The nasal length is less than the ideal value of 5mm or more, which is characterized by rounded and upwardly rotated nasal tip, exposed nostrils, and severely low nasal root and nasal back. For patients with mild short nasal deformity, the main problem is to solve the low flatness of the nasal tip, such patients can use simple nasal septum cartilage or combined with ear cartilage to shape the nasal tip, the key is to fully loosen the fibrous connection of the nasal tip. For patients with moderately severe short nasal deformity, in addition to low nasal tip, they often have low or severely low nasal root and nasal dorsum, rounded and upwardly rotated nasal tip, exposed nostrils and other problems, so simple nasal tip shaping is often unable to get satisfactory repair results, then comprehensive treatment is needed, and treatment can be carried out by cartilage transplantation nasal stent.
