Fractionally Ablative Er: YAG Laser Resurfacing for Thermal Burn Scars: a Split-Scar, Controlled, Prospective Cohort...

Thermal burn scars can have catastrophic impact on the quality of life and personal image, and over time can lead to profound physical and psychological debilitation. There are no established treatments to significantly improve burn scars.

To demonstrate the safety, efficacy, and tolerability of fractionally ablative Er:YAG resurfacing of mature burn scars.

Sixteen subjects were enrolled and received 3 treatments of fractionally ablative Er:YAG resurfacing at monthly intervals. Twelve completed the study. Scars were scored with the Vancouver Scar Scale (VSS) by the patient and physician before and after treatment. Blinded photographic analysis (Visual Analog Scale [VAS]) and blinded histologic analysis of tissue before and after treatment was also performed.

Significant Improvement in VSS scores were seen in all 12 patients, reported by patients and the evaluating physician alike. Photographic analysis demonstrated subjective improvement in all 12 patients. Histologically, there was significant improvement in collagen architecture and the number of vessels per high-power field. The treatments were tolerated well by patients, and 1 superficial skin infection occurred.

Fractionally ablative Er:YAG laser resurfacing is a safe and effective modality in the treatment of thermal burn scars with subjective and objective improvement as seen from the patient and physician.
