Pan-facial fat injection approach in young Asian patients for facial contouring: a goal-oriented classification method based on the facial fat compartments theory.

Background: In Asia, young patients tend to undergo pan-facial fat injection for facial contouring rather than for rejuvenation. Although the procedure is widely performed, there is no single approach that has been shown to have consistent results. Method: One personalized approach based on the facial fat compartment theory is presented here. Under the theory of facial fat compartments, the injection area is classified into functional zones and transition zones. A retrospective review of 105 cases over 6 years was performed to evaluate the effectiveness of this approach. Results: Follow-up ranged from 6 to 47 months. Satisfactory results were achieved in 96 percent of cases. Typical cases were also reviewed. Conclusions: In the author's view, this approach is safe, easy to learn, and produces aesthetically satisfactory results. The approach is stable and satisfactory clinical results were achieved under the guidance of the facial compartment theory, which in turn verified the accuracy of this theory.
