A Clinical Study On Application Of Autologous Fat Particles In The Breast Augmentation Surgery

Objectives 1 the research of tautologies fat granules fat particles for the purification of breast augmentation surgery operation in different ways(centrifuge method and static method) the impact on the postoperative survival rate of fat transplantation.2 use the same method(centrifugation) a injection and fat particles times a single injection of the comparison of postoperative survival rate of fat transplantation.3 Compare three methods after breast augmentation surgery, transplant survival rate of fat in the breast and muscle layer is different.Methods Experiment is divided into three groups A, B and C, Group A in 7 cases of 13 side, Group B in 8 cases of 14 side, Group C in 6 cases of 12 side, Cases in each group the same surgical method, The same fat extraction method, Injection is approximately the same level, Group A and group B only fat different purification methods, After extraction of fat group A purified by static method, Group B with low speed centrifugation purified;Group B and group C purification method is the same only different injection time and injection quantity, Group B using a single large dose injection after purification of fat particles, C group is divided into three times, each time the small dose injection,Each injection time interval of three months. Each patient clinic after the first prediction of her breast required to fill the fat mass and fat thickness and area, Preoperative routine examination, Effect comparison of preoperative day collected image data to facilitate postoperative and each layer with B ultrasound machine to measure the thickness of breast(Values can be accurate to 0.01 cm), Seven days after the operation, one month after the surgery, three month after the surgery, Pay a return visit investigation to return image data and Type B ultrasonic measurement data, Three months after surgery basic won’t change the shape of the breast. Calculation to seven days, a month after three months, the survival rate of fat transplantation, Each set of data can be used to compare each time the survival rate of fat transplantation, Compare the survival rate of group A and group B can reflect what kind of fat purification method of survival rate is higher, To compare the survival rate of group B and group C can reflect a single large injection and postoperative effect of a small amount of multiple doses.Results A group standing law lot after a single injection of augmentation measured:After 1 month average thickness of 0.38±0.06cm(survival rate 46.12% ±4.14%), After 3months average thickness of 0.30±0.04cm(survival rate 41.13%±2.99%); The muscle layer1 months after average thickness of 0.30±0.04cm( Survival rate of 47.11%±5.56%), After3 months after average thickness of 0.27±0.03cm( Survival rate of 43.52%±5.18%). B group centrifugation lot after a single injection of augmentation measured: After 1 month average thickness of 0.48±0.12cm( Survival rate of 53.09%±2.13%), After 3 months average thickness of 0.44±0.14cm(Survival rate of 48.52%±4.21%); Between the muscle layer of grafts fat average thickness of 0.41±0.11cm( Survival rate of 54.67%±3.30%),After 3 months in average thickness of 0.40±0.10cm(survival rate of 52.82%±2.80%). C group centrifugation augmentation injections three times a small amount of cases the measured data: The first postoperative month survival rate for breast layer 51.25%±1.39%,Muscle layer was 55.25%±3.32% survival rate; The second layer is the survival rate for three months after breast 50.76%± 2.16%, Muscular survival rate was 54.95%±3.12%;Third postoperative month survival rate for breast layer 49.30%±3.19%, Muscular survival rate was 56.42%±3.78%. If the total of three injections thickness and thickness to calculate survival, Breast layer was 50.39%±1.36% survival rate, Muscular survival rate was55.54%±2.59%.Conclusions 1 purification methods, low-speed centrifugal method than let stand high survival rate after operation; Centrifugal method, a few times an injection is better than a single injection of high survival rate. 2 glands muscular layer and the survival rate, the static methods by a single injection of two layers are in great quantities, survival rate was not significantly different, repeated small centrifugal method and a large number of single injection of muscular layer survival rate were higher than gland.
