Nose columella, that is, the middle part between the two nostrils, plays an extremely important role in the beauty of the nose. Common ugly nose columella include short and wide nose columella, sunken nose columella, drooping nose columella, crooked nose columella and so on. Are generally congenital, and many of them are related to the failure of nose plastic surgery. The tip of the columella is connected with the tip of the nose, and their shapes influence each other. Seen from the front, the beautiful columella will form a beautiful seagull line with the outer edge of the nostril.

The shape of the nasal septum is of great significance to the nose type, which is related to whether the nose will face the sky. Generally speaking, the higher the nasal septum, the higher the columella and the tip of the nose, and the more the lower end of the alar will become warped. On the other hand, if the nasal septum is too short, the length of the tip of the nose will be insufficient, resulting in the nose wing facing the sky and the nose is very short. Due to climatic reasons, this kind of short nasal septum is especially common in southern China. Visual inspection is an operation to lengthen the nose. The doctor will cut through the lower end of the nasal columella, put an implant such as ear, costal cartilage or nasal septum cartilage in the front end of the nasal septum, and finally sew the implant with the alar cartilage.
