Objective To explore the effects of dermabrasion combined with ReCell on large superficial facial scars caused by burn, trauma and acnes. Methods Nineteen patients with large superficial facial scars were treated by the same surgeon with dermabrasion combined with ReCell？. According to the etiology, patients were classified into post-burning group （n=5）, post-traumatic group （n=7） and post-acne group （n=7）. Fifteen patients completed the follow-ups, 5 patients in each group. Healing time, complication rate, the preoperative and 18-month-post-operative assessments using Patient Satisfaction Score （PSS）, Vancouver Scar Scale （VSS）, and Patient and Observer Scar Assessment Scale （POSAS） of each group were analyzed to compare the effect of the combined therapy on outcomes.Results The healing time of post-burning group （19.6±4.0 days）, post-traumatic group （15.8±2.6 days）, and post-acne group （11.4±3.1 days） varied remarkably （F=7.701, P=0.007）. The complication rates were 60%, 20%, and 0 respectively. The post-operative POSAS improved significantly in all groups （P〈0.05）, where the most significant improvement was shown in the post-acne group （P〈0.05）. The post-operative PSS and VSS improved only in the post-traumatic group and post-acne group （all P〈0.05）, where the more significant improvement was also shown in the post-acne group （P〈0.05）. Conclusions The combined treatment of dermabrasion and ReCell has remarkable effect on acne scars, moderate effect on traumatic scars and is not suggested for burn scars. POSAS should be applied to assess the therapeutic effects of treatments for large irregular scars.
