Nasal Column Lengthening is a common type of rhinoplasty that can effectively improve the shortness of the nasal columella and improve the appearance of the nose in a comprehensive way through Nasal Column Lengthening. It is used to correct short and low noses, to extend the nose forward and downward, and to achieve tip elevation and tip lengthening. If the nasal columella are too low, they are padded with autologous tissue or alternative non-autologous materials; if they are too high, they need to be partially removed. However, this kind of surgery has certain risks, as follows: 1, infection: the nasal area may retain more bacteria and dirt, if not cleaned properly, the possibility of infection will be greatly increased; 2, bleeding: the septum of the superficial fascia layer of the blood vessel network is relatively rich, if the operation process is not careful, there is the possibility of damage to blood vessels; 3, nerve damage: due to the richness of the nasal nerves, the surgical operation process there is a damage to the possibility, but a short period of time can be self-explanatory, and then the operation can be completed in a short time. Nasal nerve damage: due to the richness of the nasal nerve, there is a possibility of damage during the operation, but it can be recovered within a short period of time without special treatment; 4, discomfort: after the nasal columellar plastic surgery, there may be symptoms of respiratory discomfort, and in serious cases, the incision needs to be further treated, otherwise, it may result in other diseases of the respiratory system; 5, nasal shape is not good: the resection of tissues or flap suturing is not appropriate, which may affect the appearance of the nasal part after the operation; 6, the shape of the upper lip is not good: the nasolabial extension is generally used in the upper lip or nasal base. The upper lip or nasal base tissue is used, which may leave a scar in the upper lip area affecting the shape of the upper lip.
