The biggest concern in rhinoplasty is scar, contracture, nosebleed supply and other issues, so the fewer the times, the better, and it is recommended not to exceed 3 times at most. First of all, regardless of the nose, nose repair surgery is very harmful to the skin. If the repair technology is not in place, the peeling degree will be inaccurate, and the scar will be heavier, and even it will not be fully recovered in a year or two. Moreover, the damage to cartilage tissue after repair is also very serious, and it is difficult to repair it again. Secondly, for example, if the alar tissue is cut too much, the nostrils will be deformed; The wrong choice of columella incision leads to very serious scar ... in these cases, it will be more difficult to repair again.
