二次自体脂肪注射移植隆乳术后体积保持率的变化

目的 将二次自体脂肪注射移植隆乳术后体积保持率,与首次注射后的体积保持率进行对比,探索二次注射后体积保持率的变化。方法 对2011年3月至2014年12月进行自体脂肪注射移植隆乳术的病例进行回顾性研究,纳入9例患者(18侧乳房),使用三维图像技术分别计算首次注射后体积保持率和二次注射后体积保持率,采用配对t检验进行对比。结果 首次注射后平均体积保持率为0.25±0.06,二次注射后平均体积保持率为0.32±0.06,保持率显著提高(P=0.000 7)。结论 二次自体脂肪注射移植隆乳术后体积保持率较首次注射后有显著的提高。

The Change of Volume Maintenance after Secondary Autologous Fat Graft for Breast Augmentation

Objective To compare the percentage volume maintenance after the first and second autologous fat graft, and to explore the change of percentage volume maintenance. Methods From March 2011 to December 2014, 9 patients received autologous fat graft for breast augmentation were included for this retrospective study. The percentage volume maintenance after the first fat graft session and overall percentage volume maintenance after the second fat graft session were calculated using three-dimensional photography. The t test was performed to compare the results. Results The mean percentage volume maintenance was 0.25 ±0.06 after the first fat graft session, while the overall mean percentage volume maintenance was 0.32±0.06 after the second fat graft session. The percentage volume maintenance after the second fat graft session was significantly increased （P=0.000 7）. Conclusion There is a significant improvement of percentage volume maintenance after the second fat graft session.
