In the Oriental beauty population, the tip of the nose is slightly more prominent than the dorsum of the nose, and from the side view, the prominent point of the tip of the nose is in front of the dorsal extension line of the nose, and the upper lobule of the tip of the nose and the dorsal extension line of the nose form an angle of turn, i.e., the tip-dorsum of the nose angle, whose angle is about 5° to 10°; the angle between the upper and lower lobules of the tip of the nose is the tip of the nose angle, which is about 95°~110°; the angle between the lower lobule of the tip of the nose and the nasal columella is the turn of the nasal columella angle, which is about 50 °~65°; the angle at which the long axes of the two nostrils intersect is 80°~105°, which is markedly different from that of the Caucasian race and has distinct racial characteristics. From the starting point of the upper end of the nasal columella to the two sides of the nasal tip point line, the angle between the two lines is 60 ° ~ 85 °, the introduction of this angle is important in determining whether the tip of the nose is prominent or not: the tip of the nose flattens when the angle becomes larger; the tip of the nose protrudes when the angle is narrowed. On the other hand, the nasolabial angle (the angle between the nasal columella and the upper lip) is generally 70° to 90°, which is smaller than that of the Caucasian race. The size of the nasolabial angle is related to the droopiness of the nasal tip; the smaller the angle, the more droopy the tip appears. The several corners between the nasal columella-nasal tip-nasal dorsum are the key points in nasal aesthetics, and the upturning or not of the nasal tip and the degree of height of the nasal tip position are all related to this. At the same time, the length of the upper and lower lobes of the nasal tip is also related to the droopiness of the nasal tip and the prominence of the nasal tip. However, all of these aesthetic indicators are closely related to the shape of the supporting structure of the nasal tip.
