Nasolabial fold dynamics: Implications for facial paralysis and facial reanimation surgery.

ABSTRACT:

Objectives

In patients with facial paralysis, facial reanimation surgery may be needed to normalize facial soft tissue function/movements. Critical for this normalization is the dynamics of the nasolabial folds (NLFs). The objective of this prospective, observational study was to determine the 3D morphologic dynamics of the NLFs in patients with unilateral facial palsy and normal subjects.

Settings and sample population

3D facial soft tissue movement data collected from adults with unilateral, facial paralysis (Bell's Palsy, n = 36); and (2) an age- and sex-frequency matched control group (n = 68).

Materials and methods

Movement data were collected during repeated animations from participants using a video-based motion capture system. Movement in terms of displacement
