Background: The nose is located in the middle of the face; therefore, nasal scarring will bring a significant psychological impact on patients. Although there are many treatment methods for depressed scars, these methods have varying degrees of efficacy and all carry certain adverse effects. A better treatment method is urgent to be found. In this study, the effect of micro‐plasma radiofrequency technology combined with subcision to treat nasal depressed scars is evaluated. Methods: 18 Chinese patients with nasal depressed scars participated in this study. All patients received one session of micro‐plasma radiofrequency treatment first. 2 months later, subcision combined with micro‐plasma radiofrequency technology was performed on them at 6‐month intervals, and a total of 2 sessions of combined treatment were performed. Goodman and Baron Scale was used to evaluate nasal scars before treatment and 6 months after the final session. Results: All 18 patients in this study had Grade 4 nasal scars before treatment. 6 months after the end of treatment, 13 patients (72.2%) showed excellent or near total improvement, and 5 patients (27.8%) showed marked improvement. No adverse side effects were observed during treatment. Patient self‐evaluation indicated that all patients were satisfied with the cosmetic outcomes. Conclusions: In this study, we explored a new treatment method for nasal depressed scars. We used micro‐plasma radiofrequency technology combined with subcision to treat nasal depressed scars and obtained relatively satisfactory results with no adverse effects. [ABSTRACT FROM AUTHOR]
