Finally, general and specific soft tissue and bony applica- tions have been described, and the cellular activity and signaling in these settings may be medically different. As was evident from this review, although P-PRP is the original and by far the greater studied type of platelet prepa- ration, PRFM had similarly effective properties with the possible added benefit of a longer duration of effect. Since platelets in P-PRP breakdown quickly, growth factor con- centrations rise for a short period of time, after which any effect becomes less pronounced. With PRFM, the fibrin ma- trix enhances the delivery of the growth factors and allows for a greater sustained release. The added advantage of PRFM is that it can be obtained centrifugally by autologous peripheral blood without adding any biological agents or foreign mate- rials. It is relatively low in cost and easily available. The type and uses of platelet preparations vary, and there are not yet widely established and accepted uses for it in everyday plastic surgery practice despite the growing evidence demonstrating its advantages. More research needs to be done to explore the potential uses and effec- tiveness of these platelet preparations in plastic surgery. Large, robust RCTs with objective outcome measures are needed to better define the benefits of platelet preparations in facial plastic surgery. Acknowledgments Anthony P.
