Fractional microplasma radiofrequency technology for non-hypertrophic post-burn scars in Asians: A prospective study of 95 patients

Lasers Surg Med. 2017 Aug;49(6):563-569. doi: 10.1002/lsm.22640. Epub 2017 Feb 20.


Background: Laser and other energy devices are emerging, minimally invasive treatments for scars. Among the various techniques, fractional microplasma radiofrequency technology (FMRT) has proven to be an effective treatment option for various types of scars and skin conditions such as rhytids, striae distensae, and hyperpigmentation.

Objective: This prospective clinical trial was designed to evaluate the efficacy and safety of FMRT for treating non-hypertrophic post-burn scars in the Asian population.

Method: All patients underwent three to five treatment sessions at various intervals of 8-16 weeks. The Patient and Observer Scar Assessment Scales (POSAS) [20] were used to evaluate changes in burn scars pre-and post-FMRT treatment.

Results: A total of 95 patients completed the study. The overall response rate was 86.3% (82/95). The total POSAS scores before and after 6 months of treatment were 53.41 ± 6.28 and 46.35 ± 5.30, respectively. There was statistically significant improvement in scar color, thickness, and pliability. There was no improvement in vascularization, pain, or itching. Complications included prolonged post-inflammatory hyperpigmentation, acne eruption, herpes simplex eruption, and abnormal hair growth. No severe adverse events, such as acute skin infection, hypertrophic scarring, or depigmentation, were observed.

Conclusion: FMRT is an efficacious, safe treatment for non-hypertrophic burn scars in the Asian population. Lasers Surg. Med. 49:563-569, 2017. © 2017 Wiley Periodicals, Inc.
