Abstract (original English)

Background Congenital hypoplasia of facial bones has traditionally been treated by orthognathic surgery. However, the inherent invasiveness of orthognathic surgery often leads to a high complication rate. Facial fat grafting could be a less invasive method to correct facial deformities. Objectives The aim of this study was to evaluate the results of microfat grafting for facial contouring. Methods This retrospective chart review evaluated 166 patients who were treated with microfat grafting for maxillary and/or mandibular hypoplasia. Pretreatment and posttreatment photographs were compared regarding improvement of facial contour, and complications were recorded. Results The follow-up period ranged from 4 months to 10 years (mean, 2 years 7 months). Thirty-eight percent of the patients had a refill procedure 6 or more months after the first procedure. A majority of the evaluated patients stated that they benefited from the microfat grafting, with ratings of excellent (50%), sufficient (48%), and poor (2%). Complications included visible fat lobules under the lower eyelid skin (7%), which was seen during the first 4 years and was resolved by changing the injection cannulae and technique, and fat resorption, which was seen in all patients, with a clinical range from ±15% in the immobile malar area and chin region to ±50% in the mobile lip area. Conclusions Facial microfat grafting
