Influences of improved low negative pressure mechanical liposuction and syringe liposuction on breast augmentation by autologous fat grafting

Abstract

Objective To investgate the efficiency of autologous fat grafting for breast augmentation by improving low negative pressure mechanical liposuction. Methods A total of 37 cases of breast augmentation by autologous fat grafting were reviewed; group A included 19 cases of improved low pressure mechanical liposuction, and group B had 18 cases of traditional syringe liposuction. Respectively, the operating time of harvesting 800 ml fat granules (standing 30 mins) were recorded, and operative blood loss by testing the red blood cell count of lower mixed liquid was calculated, and then growth increment of nipple chest circumference of 6 months after operation were measured. The valid follow-up satisfaction scores were counted. Results The operating time of harvesting 800 ml fat granules were (53.32±4.73) mins for group A and (80.78±7.86) mins for group B, respectively; operative blood loss was (81.58±10.80) ml for group A and (72.94±13.45) ml for group B; All P<0.05. The valid follow-up satisfaction scores were 78.9% (15/19) for group A and 77.7% (14/19) for group B. Growth increment of nipple chest circumference of 6 months after operation between groups were no statistical significance (P0.05); but the remarkable difference within both groups in internal comparison existed between 6 months and 1 month after operation (P<0.05), also between 3 months and 1 month after operation (P<0.05). Conclusions Improved low pressure mechanical liposuction in breast augmentation by autologous fat grafting is able to enhance the surgical efficiency evidently and shorten the operating time significantly.
