{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.
