Comparison of two methods of subcision Nokor and blunt blade in acne scars treatment.

CONTEXT: Subcision is a simple surgical method that can be effective in treatment of acne scars. AIMS: This study was conducted to evaluate and compare the two methods of Nokor needle and blunt blade (BB) subcision in treatment of acne scars. SETTINGS AND DESIGN: This clinical trial study was conducted on 28 patients with acne scars. PATIENTS AND METHODS: One side of the face was treated with BB subcision method, and the other side was treated with Nokor needle method. Followed up period was 6 months after treatment. STATISTICAL ANALYSIS USED: Data were analyzed by Statistical Package for the Social Sciences (version 20) software using independent sample t test, Mann-Whitney test, Friedman test, and Fisher's exact test. RESULTS: In follow-up period, the improvement of acne scars was comparable in both groups (P > 0.05). Complications were lower in BB method than another method (P < 0.05). The patient satisfaction was higher in BB method (P < 0.05). CONCLUSIONS: Both of modalities offered similar improvement, but the complication rate was lower and the patient satisfaction was also higher in the BB method than another method.
