Effectiveness and Safety Analysis of Plasma Beam in the Treatment of Facial Depressed Scars

OBJECTIVE: The study aimed to analyze the effectiveness and safety of microplasma beam in the treatment of facial depression scars. METHODS: 106 patients with facial depression scars treated in the hospital between January 2017 and September 2021 were selected as the observation subjects. According to different treatment methods, the patients were divided into the control group (receiving ultrapulsed carbon dioxide lattice laser treatment, n = 51) and the observation group (undergoing plasma beam treatment, n = 55). The two groups were treated for 6 months, and the treatment effects were compared between the two groups. The Visual Analogue Scale (VAS) was used to compare the pain between the two groups, and the duration of pain and the time of scab shedding were recorded. The improvement of scars was compared between the two groups according to the Evaluation Clinique des Cicatrices d' Acne (ECCA), and the adverse reactions during treatment were compared between the two groups. RESULTS: A clinical effective rate of 94.55% in the observation group was higher than a clinical effective rate of 82.35% in the control group (P < 0.05). The VAS score in the observation group was lower than that in the control group, and the pain duration and the scab shedding time were shorter than those in the control group (P < 0.05). ECCA scores in the observation group after twice and 3 times of treatments were lower than those in the control group (P < 0.05). The total incidence rate of adverse reactions of 10.91% in the observation group was lower, whereas it was 25.49% in the control group (P > 0.05). CONCLUSION: Plasma beam has a significant efficacy in the treatment of facial depressed scars, and it has mild pain, quick recovery, and high safety. Clinical Trial Registration Number.
