Abstract:

BACKGROUND: Presently, slight and repeated injection is a good method to elevate the survival rate of implanted fat tissue.
OBJECTIVE: To explore the clinical application of autologous purified freezing microparticle fat injection in facial rejuvenation.
METHODS: Totally 64 facial aging patients presenting with atrophy and depression of facial soft tissue were treated with injecting transplantation of microparticle fat which was obtained from patient’s abdomen or thighs by using tumescent liposuction technique. Microparticle fat was purified by low-speed and low-pressure centrifugal, then undergoing -20 ℃ hypothermic freezing and 37 ℃ rewarming for 1 hour. Vitality of fat tissues was detected.
RESULTS AND CONCLUSION: Totally 21 cases of 64 cases (186 positions) received one time injecting transplantation, 35 cases received two times injecting transplantation, and eight cases received three times injecting transplantation. All the patients were followed for 6 months, the effects were satisfactory and there was no complication. Autologous purified freezing microparticle fat injecting transplantation is characterized as low absorptivity, duplicate injection, and acceptable easily.
