There are two types of rhinoplasty: closed and open. In closed rhinoplasty scars are inside the nostrils so can't be seen. In open rhinoplasty there is a very small scar, about 3 mm with at the base of the nose, which usually heals so well that is hardly seen even for a specialist. More than that, to be seen, you bust recline your head backward to show your nostrils, which is pretty unusual in a normal social activity. Anyway I don't consider that is an issue for choosing the type of rhinoplasty: closed or open, let your surgeon decide what fits you best. In some more difficult cases, you just can't do it right with the closed method, you need to do it open in order to get the best result.
