Introduction:
Post-burn hypertrophic scars are an important cause of physical discomfort, limitation of movements, psychological disorders, low self-esteem and reduced quality of life. Treatment for this condition is complex and involves several options. Microneedling, also known as minimally invasive percutaneous collagen induction, is an affordable minimally invasive option that can be combined with other treatments, including ablative ones.
Objective:
The goal of this study was to present our microneedling approach for the treatment of hypertrophic scars after burns.
Method:
A prospective study of 15 patients with post-burn hypertrophic scars was conducted between October 2016 and June 2022. All patients were treated with microneedling and drug delivery of triamcinolone. Scars were evaluated using Vancouver Scar Scale (VSS), Burn Scar Assessment Scale (BSAS) and angle measurement for amplitude of movement evaluation of joints.
Results:
A significant improvement in the VSS score was obtained after microneedling (8.8 ± 0.44 to 4.1 ± 0.98; p = 0.012), especially in the acute group (less than 1 year after burns): 9.3 ± 0.49 to 3.5 ± 1.36; p = 0.041. There was a significant and progressive improvement of the scars throughout the treatment sessions in all criteria evaluated and in the ranges of joint movement (p = 0.012).
Conclusion:
Our microneedling protocol promoted a significant improvement of post-burn scars, especially in acute hypertrophic scars, and in the amplitude of joint motion. Sequential treatments provided progressive improvement.

The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
