A basic study and clinical trial of 585 nm pulsed dye laser in the treatment of congestive scars / 中华整形外科杂志

<p><b>OBJECTIVE</b>To study the biological effects of 585 nm pulsed dye laser (FLPDL) in the treatment of congestive scar.</p><p><b>METHODS</b>By histological study, collagen VG staining and microvascular staining, we investigated the changes of collagen fibers and the density of microvessels in the congestive scars after FLPDL treatment.</p><p><b>RESULTS</b>Histological and immunohistochemistry examinations showed that FLPDL achieved normal vascularity in the scar after over 3 times of treatment.</p><p><b>CONCLUSIONS</b>PDL treatment can change fundamentally the physiology of wound healing if applied in the early phases.</p>
