Your question and photos are excellent because they show a very important side effect of rhinoplasty, which most commonly can result from an open rhinoplasty. The reason for this is that during surgery a number of stiff cartilage columella struts may be sutured to the bottom of the septum in order to help change the shape of the tip. This can cause the tip to become extremely stiff and hard. So when you smile and the upper lip moves upward against an immovable tip, an unsightly crease or fold can develop within the lip. Although this occurs occasionally, it may resolve with time, but can become permanent and difficult to correct. You must be aware that it is a possible complication of certain types of rhinoplasty and ask your surgeon about it before you go under the knife.
