Short columella is a common nasal defect. In the face of this defect, the nasal columella lengthening is generally used to improve the problem, which can reshape a perfect nose shape.

1. Nose columella is too wide: too much crescent-shaped tissue is cut off at the inner edge of nostril, and at the same time, the inner sides of alar cartilage are pulled together for suture, so that the width of nose columella is reduced and the height of nose columella is increased.

2. Nose columella is too low: the base of nose columella is pushed by "V-Y" shaping method to transplant skin flap or auricle composite tissue to make nose columella higher.

3. Nose columella collapse: Nose columella depression is caused by congenital or surgical nasal septum injury. Between the front end of nasal septum and nasal columella, autologous cartilage transplantation can be used to correct it, or nasal columella can be added to support it.

4. Nose columella drooping: Three methods are used to correct it according to different situations: anterior nasal septum resection, membranous nasal septum resection and medial forefoot resection.
