According to domestic data and clinical experience, the hump nose of China people is generally shallower than that of foreigners, with wider back, wider alar and longer nose tip, which is much less than that of westerners. Most people can correct it by chiseling off the hump. Unless the back of the nose is obviously widened, it is generally not necessary to saw off the joint between the maxilla and the nasal bone with a nasal saw, so that the nasal bone can be reassembled to form a new nasal cone, and some only need to be slightly trimmed with a bone file; For those with low nasal dorsum, L-shaped solid silicone rubber nasal prosthesis can be filled to correct the nasal shape.
The specific methods of humpback correction are as follows:
1, intranasal approach: total rhinoplasty by intranasal approach. This method first makes an incision between the nasal cartilage and alar cartilage in the nostril, then removes the hump on the back of the nose, and then files the sections of bone and cartilage with a bone file. Then, rhinoplasty is completed by narrowing the rear and lower parts of the nose. Intranasal approach is more suitable for plastic surgery in Europe and America and a few people with high external nose in China.
2. External nostril approach: total rhinoplasty through external nostril approach. In this method, a nostril margin incision is made at the junction of the middle 1/3 and the lower 1/3 of the nasal column with the anterior edge of the medial foot and lateral foot of the alar cartilage. Through the skin incision, the skin of the external nose is lifted to the lower edge of the nasal bone, and the nasal bone and the periosteum on its surface are cut through the periosteum incision. External nostril approach is suitable for rhinoplasty for most people in China. No matter which method of augmentation rhinoplasty is used, nasal packing and external splint fixation should be done after operation.
