Nose columella is the middle part of two nostrils, thin and straight, and the most beautiful. The defect of columella is common, and most people ignore this important part after rhinoplasty. Lengthening nasal columella is to correct it in different ways according to different conditions around nostrils and nasal columella. If the columella is too low, it should be filled with autologous tissue or replaced with non-autologous material, and if it is too high, it needs to be removed. After operation, the length of nasal columella was moderate and not skewed. The effect is very obvious, the nose becomes tall and straight, and the overall image of the face is instantly improved. Experts pointed out that the main indications of nasal columella lengthening are nasal collapse, short nasal columella, drooping nose tip, rabbit lips and other symptoms. At present, the main materials used for nasal columella lengthening are autologous materials, allogenic materials or allogenic materials and tissue substitutes. Autologous materials include autogenous costal cartilage and nasal septum cartilage. There is no rejection to the nose for life.
