Objective To investigate a new technique to increase the survival rate of free autogenous pellet fat graft. Methods Many methods were used to graft free autogenous fat, and the results compared to look for the best method for it. Results After 3 and 6 months, the volume rate in the treatment group and control group were 70%, 60% and 40%, and 30%. The times of fat injection were 2 and 4 . Conclusion Some vasodilators, low negative pressure and plasma can enhance the survival rate of free autogenous pellet fat graft. Key words: Pellet fat;  Free graft;  Survival rate
