Facial Contouring Surgery with Custom Silicone Implants Based on a 3D Prototype Model and CT-Scan: A Preliminary Study

Background From perspectives of differences in anatomic and cultural characteristics from Caucasians, Asians have been considered to undergo facial bone contouring surgery of the zygoma and mandible and fat grafting in the anterior mimetic area of midface. We have sought to develop more ready-to-use methods for increasing the applicability of custom facial implants in the field of esthetic surgery. Patients and Methods We performed insertion of custom silicone implants after taking a clinical history and photographs in a total of seven patients ( n = 7) between March 2008 and July 2014. Our clinical series of patients comprises two men and five women, whose mean age was 41.6 ± 21.6-years old (range 23–82 years). In addition, the patients were followed up during a mean period of 11.43 ± 6.68 months (range 3–24 months). In the current study, we evaluated treatment outcomes of custom silicone implants using polyvinyl alcohol (PVA) in facial contouring surgery by reviewing seven cases. Results There were no abnormalities of the soft tissue or bone due to the use of custom silicone implants. Moreover, we found that custom silicone implants were advantageous in predicting treatment outcomes. All the patients were satisfied with treatment outcomes. Conclusion Custom silicone implants based on the PVA clay on the 3D RP model will play a prominent role in facial contouring surgery but its full potential deserves further studies.
