Before nostril plasty, we should draw lines according to the parts with too many alars. Generally, we should cut off some alar tissues along the alar, and cut off the redundant alar parts in an arc shape. Then nostril plasty forms a skin flap according to the former method, releases the tissue at the bottom of the alar, then removes part of the tissue and sutures it with a nose column. After nostril plastic surgery, the whole nose can look more delicate, and the effect of changing the shape or size of the nose can be obviously seen, and it can be effectively improved into a delicate nose shape that is in harmony with the face.
