Subcision is a new technique for the treatment of acne scars. Objective: To assess objectively and subjectively the efficacy and safety of subcision in the treatment of depressed acne scars. Patients and Methods: This is an open-label therapeutic trial. A total of 16 patients were enrolled in this study. Twelve were males and 4 were females. Their ages ranged from 19 - 39 with a mean of 26.64 ± 5.64. The duration of scar varied between 6 months and 10 years with a mean of 4.14 ± 2.54 years. subcision was done by introducing a sterile, hypodermic, 18-gauge needle. The needle was held by a three ml syringe for better orientation of the sharp tip of the needle. It was kept horizontal to the skin surface with the bevel up, and was introduced in a high sub dermal plane. The needle was slowly advanced parallel to the skin surface. Initially, rapid, repetitive linear back-and-forth motion of the needle makes the skin free of the underlying scar. This procedure was repeated in all directions in a fan-like manner. Results: According to Modified Sharquie’s scoring system for grading acne scars, 4 (25%) patients had severe grade, 11 (68.8%) patients had moderate grade and only 1 (6.2%) patient had mild grade. Evaluation at 6 months after treatment revealed that 8 (50%) patients had mild acne scar, 7 (43.8%) had moderate acne scar and only 1 (6.2%) patient still had severe grade. This change in the grades was statistically significant (p-value = 0.01713441). The average score before treatment was 13.13 ± 2.363;it became 9.50 ± 2.944 after 6 months. By paired t-test comparison, the difference in the score was statistically highly significant (p = 0.000044). Regarding the photographic assessment, the difference in the visual analogue scale before and after treatment was statistically sign展开更多
