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.

Second, the nasal columella is too low: V-Y shaping is used to promote skin flap or auricle full composite tissue transplantation, and the base of nasal columella is transplanted, so that the nasal columella is raised.

Third, the collapse of the nasal columella: the depression of the nasal columella is caused by congenital or surgical nasal septum injury. Autologous cartilage transplantation can be used to correct the nasal septum between the front end and the columella, and the columella support can be increased.

Four, nose columella drooping: through anterior nasal septum resection, membranous nasal septum resection, medial forefoot resection, three methods are corrected according to different situations.
