Aesthetic nasal evaluation requires the nose to be analyzed both as an independent facial unit and in terms of its size, morphologic characteristics, and position relative to its neighboring facial structures and the entire craniofacial complex. Nasal tip projection describes an actual change in the distance from nasal ala to tip, that is, the alar-tip distance. If there is increased tip projection, the nasal tip extends an excessive distance from the face and is perceived as disproportionately prominent.
