Controlled histological evaluation finds differences in scar structure after STSG versus dermal template plus STSG in burn survivors, suggesting new assessment methods.
Key Points
This research aims to evaluate long-term scar outcomes from split-thickness skin grafts (STSG) compared to dermal scaffold (DRT) plus STSG in burn survivors.
Invited long-term burn survivors who underwent STSG and DRT + STSG procedures.
Applied clinical measurements and POSAS evaluation on scars from both treatment methods.
Obtained and processed biopsies to assess histological properties using ImageJ and developed new scoring system for evaluation.
Conducted semi-quantitative analysis focusing on collagen fiber metrics and epidermal characteristics.
No statistical differences were found in collagen metrics between STSG and DRT + STSG scars in the analyzed subset.
Noted structural differences in scar characteristics, such as rete peg presence and length.
Epidermal and dermal alignment differed, with STSG showing thicker epidermis and less organized dermis compared to DRT + STSG.
