Abstract (original English)

We report our experience of using autologous fat grafting (AFG) as an adjunct to dynamic and static facial reanimation surgical techniques in patients with facial palsy. A consecutive series of patients with facial palsy (congenital or acquired) treated by AFG between September 2007 and October 2017 were reviewed. Multiple strategies for initial dynamic facial reanimation have been utilized. Indications for AFG included asymmetry, volume deficiency, and visible muscle tethering. Standard AFG technique was used with fat harvested from the lower abdomen or thigh and injected into multiple affected areas. Fat grafting was repeated as necessary. Two-dimensional analysis was performed using standardized pre- and postoperative photographs to assess facial symmetry. Patient, surgeon, and independent evaluator satisfaction was recorded using a five-point Likert scale (0-4). Thirty-two patients with a mean age of 43 ± 15.5 years were treated with AFG following facial reanimation. A mean of 1.7 ± 1.4 secondary procedures were performed following initial dynamic reanimation before fat grafting. The average number of AFG episodes was 2.2 ± 1.4 with a mean volume of 12.9 ± 6.0 ml. Minimal complications were seen in either the donor or the recipient sites. There was significant improvement ( P ≤ 0.001) of postoperative quantitative facial symmetry following fat grafting. At one-year follow-u
