Facial Contour Symmetry Outcomes after Site-Specific Facial Fat Compartment Augmentation with Fat Grafting in Facial Deformities

Facial Contour Symmetry Outcomes after Site-Specific Facial Fat Compartment Augmentation with Fat Grafting in Facial Deformities: Background:

The purposes of this study were to evaluate facial symmetry after the first fat grafting session in patients with unilateral facial contour deformities and to identify independent predictors of 12-month postoperative facial symmetry.

Methods:

A prospective analysis was conducted of consecutive patients (n = 167) that underwent fat grafting to restore facial contour symmetry. Computerized photogrammetric facial symmetry analyses were performed. Bivariate and multivariate analyses were executed to identify independent predictors of 12-month postoperative facial symmetry.

Results:

There were significant (all p 0.05) from 3 to 12 months postoperatively, with a 12-month facial symmetry of 91.2 ± 6.9 percent (ranging from 79.8 to 99.3 percent). Sixty-six complementary facial fat grafts (39.5 percent) were performed for residual asymmetry. Age, Parry-Romberg syndrome, previous facial bone surgery at the site that received fat grafting, and injected volume were independently negative (all p
