Objective To evaluate the methodology and clinical efficacy of autologous fat grafting for the reconstruction of facial depressed and atrophic scars. Methods 10 patients with facial depressed and atrophic scars were treated with autologous fat grafting.Fat harvest, refinement and injection were done by 3M3L's fat grafting technique. Every patient was treated 1- 3 times with an interval of 3- 6 months.The improvement of facial contour deformity and skin texture were assessed after surgery. Results All patients were followed up postoperatively within 3- 12 months.No complications such as infection,cysts,calcification, vascular or nerve injury occurred,nor new deformity and scars were observed.The contour deformity was corrected significantly compared before. The local skin texture of scars was also improved greatly.Patients were all satisfied with the cosmetic results. Conclusion Although further studies are required to provide surgeons with definitive guidelines for the implementation of fat grafting,we propose autologous fat grafting is a feasible minimally invasive and safe technique for facial depressed and atrophic scars.%目的：探讨自体脂肪移植修复面部凹陷性及萎缩性瘢痕的方法和临床疗效。方法：对10例面部凹陷性及萎缩性瘢痕患者采用自体脂肪移植进行治疗。脂肪获取、提纯及注射采用3M3L移植技术。每例自体脂肪移植1～3次，每次间隔3～6个月，综合评价患者术后面部轮廓畸形、瘢痕皮肤质地改善情况。结果：患者均获随访3个月～1年，无感染、囊肿、钙化、血管和神经损伤等并发症发生，也未产生新畸形及新瘢痕。轮廓凹陷畸形得到矫正，瘢痕皮肤质地及色泽有所改善，患者均对治疗效果满意。结论：自体脂肪移植是一种治疗面部凹陷性及萎缩性瘢痕可行的微创方法。
