The effect of rhinoplasty on perceived age.

摘要

The aging nose tends to undergo characteristic changes. With increasing age, there is weakening of the major and minor nasal tip support mechanisms leading to nasal tip deprojection and development of the so-called dorsal pseudohump. Furthermore, liga-mentous laxity leads to lobular descent, causing nasal lengthening and counterrotation. Posterior-superior remodeling of the premaxillary bony skeleton, which acts as the platform for the nasal base (ie, midface retrusion), also contributes to a more acute nasolabial angle (NLA).
