ABSTRACT
Objective To explore the effect of different harvest methods of liposuction on the autologous fat grafting.Methods The clinical data of 60 patients with fat grafting for breast augmentation from January 2014 to January 2017 were analyzed retrospectively.According to the method of liposuction,60 patients were divided into the water-jet assisted liposuction group (30 cases) and negative-pressure machine liposuction group (30 cases).The surgical time of different liposuctions and the fat survival were compared after breast augmentation.The clinical effect of different liposuction methods was analyzed by follow-up one year after operation.Results Sixty patients completed the surgery.The fat survival rate of water-jet assisted liposuction was (66.71±2.68) ％,and the fat survival rate of the negative-pressure machine liposuction was (51.44 ± 1.16) ％.There were statistically significant difference between the two groups (P＜0.05).As for the operation time of liposuction,the water-jet assisted liposuction group was (33.28 ± 2.96) min,the negative-pressure machine liposuction group was (52.91± 5.03) min;there were statistically significant difference between the two groups (P ＜ 0.05).There was no statistically significant difference in satisfactory rate (P＞0.05).Conclusions Compared with negative pressure liposuction,water-jet assisted liposuction using autologous fat grafting in breast augmentation can improve the survival rate of fat transplantation.This technique has good clinical application value.
