1. Excision of long alar cartilage: the lower end of long bilateral alar cartilage or the upper and lateral parts of the lateral corner of alar cartilage are excised through the nostril margin incision. This method is also suitable for rhinoplasty.

2. Excision of the cartilage of the long nasal septum: The cartilage of the long nasal septum is excised from different directions through the longitudinal incision at the front edge of the nasal septum to correct the bulging deformity of the corresponding part.

3. Cutting off the hypertrophy and hyperplasia of the descending nasal septum: cutting off the descending nasal septum in the deep layer of the orbicularis oris muscle near the maxillary incisor fossa.

4. Trim and remove too much skin on the tip of the nose: after removing the above-mentioned long cartilage, the skin on the tip of the nose has no obvious change. In severe cases, the skin on the tip of the nose is redundant and can be retracted without treatment. If many soft tissues are redundant, they can also be trimmed to shape the corrected nasal tip.
