摘要目的 探讨三维扫描系统评价细胞辅助自体脂肪移植(CAL)面部填充效果及其对脂肪成活率的影响.方法 2016年2—5月于北京大学深圳医院整形外科门诊要求行自体脂肪移植面部填充患者中选出14例,其中7例行CAL面部填充(CAL组),CAL组患者取部分新鲜脂肪组织送实验室制备血管基质片段,将血管基质片段与脂肪混合后移植;7例行传统自体脂肪移植(对照组).13例患者分别于术前 、术后1周 、术后6个月行三维面部扫描,建立面部数字模型,计算移植脂肪成活率.结果 CAL组平均脂肪移植量13.86 ml,对照组平均脂肪移植量12.14 ml,两组比较脂肪移植量差异无统计学意义(P>0.05).经三维扫描系统计算,CAL组患者平均脂肪成活率37.82％,对照组患者平均脂肪成活率27.54％,两组脂肪成活率差异有统计学意义(P<0.05).结论 三维扫描系统能够提供面部脂肪移植术后的脂肪体积等相关数据,能够计算脂肪成活率.细胞辅助自体脂肪移植可能增加移植脂肪成活率.

abstractsObjective 3D-scanning system is put in use to evaluate the comparative effect be-tween the cell-assisted lipotransfer (CAL) and traditional autologous fat transplantation ,which aims to definitize the survival rate of fat after CAL and provide a reference for the clinic .Methods Fourteen cases were collected among patients aquiring facial autologous fat transplantation from February to May 2016 from the hospital out-patient department ,which were then divided into two groups equally and randomly .7 patients used traditional autologous fat transplantation form the control group and the rest 7 used the CAL .Autologous fat sample of the CAL group was grafted with stromal vascular frac-tion (SVF) .All the patients received follow-up examination and the period lasted at least 6 months . 3D-scanning of facial models were conducted sometime before surgery ,a week after surgery and also 3 months after surgery .Results The average transplantation volume of CAL group was 13 .86 ml while the control group was 12 .14 ml .There were no significantly differnt in the transplantation volumes of the fat (P > 0 .05) .The survival rate of fat in CAL group was 37 .82％ while the control group was 27 .54％ after calculating the changing volume from the facial models .The survival rate of fat in CAL group was significantly higher than that in the control group (P < 0 .05) .Conclusions 3D-scanning system can provide the data concerning the lipotransfer and calculate the survival rate of the fat .CAL can raise the survival rate of the fat .
