The nose can be reduced by cutting off the l/2-2/3 on the cartilaginous side of the alar and rotating the lateral foot to the medial side and the cephalic side. At this point, you can see the alar adduction. This operation is to cut off the cartilage intermittently at the alar cartilage vault, which cannot be cut off. Therefore, in order to strengthen the nostril or transverse nostril, wedge resection at the root of the alar has a very good effect of rhinoplasty, but the postoperative nursing work must be strictly implemented.
