People tend to have a bulbous nose when their nose is large or the soft tissues are thick. It is important to have a skilled doctor for several reasons. First, if the soft tissues are imprecisely removed, you may result in an uneven nose shape or excess thinning of the nose tip, disturbing your blood circulation. When the cartilage is knotted too tightly, it may cause concavity. For such reasons, operations should be performed by an experienced surgeon.
