The width and angle of the alar, the shape of the nose and the tip of the nose, and the shape of the nostrils will also affect the beauty of the nose. Lengthening of nasal columella can be corrected by different surgical methods according to different conditions around nostrils and nasal columella. If the columella is too low, it can be filled with autologous tissue or replaced with non-autologous material. If it is too high, it needs to be removed. After the operation, the length of nasal columella is moderate and will not be skewed, and the effect is obvious. The nose becomes taller and has a three-dimensional effect, and the overall image of the face is improved.
