The Efficacy of Microneedling and Platelet-Rich Plasma in the Treatment of Breast Reduction Scars: A Prospective Study

Background Incisional scars are among the most critical factors influencing postoperative satisfaction for both surgeons and patients. Although the majority of patients undergoing reduction mammoplasty report high overall satisfaction with the procedure, a significant proportion remain dissatisfied with the appearance of their scars.This study investigates the efficacy of combining platelet-rich plasma (PRP) with microneedling (dermapen) in the treatment of incisional scars.MethodsA prospective, single-blind study design was employed. Twenty patients who had reduction mammoplasty and presented to the outpatient clinic with complaints related to scarring were divided into two groups.In the first group, microneedling was performed using a dermapen for 15 minutes, moving vertically and horizontally over incisional scars. In the second group, dermapen treatment was applied for five minutes to create microchannels, followed by topical PRP application, then continued for ten more minutes. Procedures were conducted in two sessions, three weeks apart. At six months, objective and subjective evaluations using VAS and statistical analyses were performed..ResultsBoth groups demonstrated significant improvement in scar healing; however, the addition of PRP did not provide any additional benefit. No severe complications were observed among the patients, and all resumed their daily activities without disruption. Furthermore, no cases of hypo- or hyperpigmentation were recorded.ConclusionCurrently, there are limited effective treatment modalities for incisional scar management. Both techniques evaluated in this study were found to be safe and effective for the treatment of both mature and immature incisional scars across all skin types.
