Esthetic nasolabial angle according to the degree of upper lip protrusion in an Asian population

摘要

Background: The positioning of the nasal tip is as esthetically important as the tip projection when rhinoplasty is being considered. It is not uncommon for Asians to have a protruding upper lip and teeth that affect the nasolabial angle (NLA). This study aimed to find the preferred NLA according to the degree of upper lip protrusion in an Asian population.
