Facial mobility and recovery in patients with unilateral facial paralysis.

ABSTRACT:

Objective

(a) To quantify longitudinal 3D changes in facial soft tissue movements in adults with unilateral facial paralysis, and (b) to compare the patients' movements with an age- and sex-frequency matched control group.

Settings and sample population

Prospective 3D facial movement data of 36 patients and 68 control participants. Patients' data were collected within 6 weeks of onset of symptoms (baseline) and then at 3 and 12 weeks after baseline.

Materials and methods

The 3D facial movement data were collected during different facial animations. Mean group measurements of displacement, velocity and asymmetry were computed. Two sample t tests were used to test for significant group differences, and linear mixed models were fit to test for significant changes over ti
