BACKGROUND: Facial contour deformities usually result from congenital abnormalities, trauma, and the aging process. All depressions in the face, including glabella wrinkles and mild retrogression of chins, fall in this category. Local injection of autogenous fat parcels has been introduced for correction of these facial deformities for almost 20 years. METHOD: Using common materials (gauzes and cotton sticks), a simple technique was used by us to purify syringe-suctioned fat parcels followed by a multilayered injection of the purified fat tissue into implantation sites to treat the facial contour deformities in 152 sites of 50 cases with successful outcomes. RESULTS: Thirty-nine sites in 17 cases were followed up from 13 months to 37 months (average, 22.8 months). The injected fat parcels deposited successfully and the increasing volume maintained well. The impact factors on the successful deposit of the injected fat parcels included the extent of mechanical injuries to the fat cells during liposuction and lipoinjection, application of the purification procedure, and postsurgery immobilization as well as the blood-nourishing situation of recipient sites. Postoperative complications included undercorrection, overcorrection, small fat mass, unevenness, or irregularity. CONCLUSION: The introduced purification and injection techniques provided a comparative simple and reliable method in facial recontouring treatment. The local volume could be increased successfully by means of controlling the influencing factors of fat parcel deposit.
