Abstract：
BACKGROUND: Severe atrophic acne scars (AAS) remain the \"Achilles\'s heel\" of AAS treatment. The combination of microfat and subcision treatment is a potential solution for severe AAS.
OBJECTIVE: This study aimed to evaluate the efficacy and safety of combined microfat and subcision treatment for severe (Grade 4) AAS.
METHODS: Data of patients with Grade 4 AAS who underwent combined microfat and subcision treatment between September 2016 and December 2020 were reviewed. Post-treatment evaluation was performed at least 3 months postoperatively. The severity of AAS was graded based on Goodman\'s qualitative classification. The volume of concavities was measured using an Antera 3D camera. Complications were documented.
RESULTS: A total of 42 patients received a single treatment session. Excellent response was observed in 5 (11.9%) patients, very good in 13 (31.0%), good in 22 (52.4%), and poor response in 2 (4.7%). The average reduction of the total volume of concavities was 28.0%. The most common minor side effects were mild swelling and bruising. No major complications were observed.
CONCLUSIONS: Combined microfat and subcision treatment is a safe and effective treatment for severe AAS. The approach will be a significant treatment for severe AAS.

摘要：
背景：严重萎缩性痤疮疤痕（AAS）仍然是AAS治疗的“致命弱点”。微脂肪和切除治疗的组合是严重AAS的潜在解决方案。
目的：本研究旨在评估微脂联合切除术治疗重度（4级）AAS的疗效和安全性。
方法：回顾了2016年9月至2020年12月期间接受微脂和切除术联合治疗的4级AAS患者的数据。术后至少3个月进行治疗后评估。AAS的严重程度根据Goodman的定性分类进行分级。使用Antera3D相机测量凹陷的体积。并发症已记录在案。
结果：共有42名患者接受了一次治疗。在5例（11.9%）患者中观察到良好的反应，在13个（31.0%）中非常好，在22（52.4%）中表现良好，反应不佳的有2人(4.7%)。凹陷的总体积平均减少28.0%。最常见的轻微副作用是轻度肿胀和瘀伤。未观察到重大并发症。
结论：微脂联合切除术是治疗重度AAS安全有效的方法。该方法将是严重AAS的重要治疗方法。
