Abstract
BACKGROUND: This study aimed to investigate the efficacy and safety of CO(2) fractional laser combined with Mebo burn ointment in treating facial postoperative scars. METHODS: Sixty patients with facial postoperative scars in the department of plastic surgery of Sun Yat-sen Memorial Hospital from January 2020 to June 2022 were divided into a control group (30 cases) and a study group (30 cases). Both groups received CO(2) fractional laser treatment, but the study group also received Mebo burn ointment application. RESULTS: The study found that both methods resulted in a significant decrease in Sawada score and a significant increase in Investigator Global Assessment score after treatment (P < 0.05), with the study group showing a more significant improvement and higher patient satisfaction (P < 0.05). All patients experienced varying degrees of bleeding, swelling, and erythema immediately after treatment, with two cases of pigmentation and two cases of persistent erythema in the control group, and one case of pigmentation and one case of persistent erythema in the study group. Adverse reactions were minimal, with the study group showing better tolerance. CONCLUSIONS: The study suggests that CO(2) fractional laser combined with Mebo burn ointment is an effective and safe treatment for facial postoperative scars.
