A comparison on the scar development when done through overlapping versus approximating seams techniques - A clinical...

Area of Science:

• Plastic Surgery
• Wound Healing
• Dermatology

Background:

• Skin autografting is a standard procedure for deep burn wounds.
• Scarring at the graft site remains a significant surgical challenge.
• Existing methods to reduce scarring have yielded conflicting results.

Purpose of the Study:

• To compare the efficacy of two Seams techniques, approximating (AP) and overlapping (OV), in minimizing scar development after skin autografting.
• To evaluate scar formation using the Vancouver Scar Scale (VSS).

Main Methods:

• A double-blind randomized trial involving 36 patients with deep burns (10-50% TBSA) requiring grafting.
• One graft edge was secured using the AP technique, and the other using the OV technique (1-2 mm overlap).
• Scar assessment via VSS at six months, with statistical analysis using SPSS (P < 0.05 significance).

Main Results:

• The AP technique demonstrated statistically significant improvements in pigmentation (P=0.014), pliability (P=0.008), and scar height (P<0.001) compared to the OV technique.
• Vascularity Scar index showed no significant difference between the two techniques (P=0.564).
• The overall Vancouver Scar Scale score was significantly better with the AP technique (P<0.001).

Conclusions:

• The approximating (AP) Seams technique is superior to the overlapping (OV) technique for reducing scar formation after skin autografting.
• AP technique leads to better scar characteristics, including pigmentation, pliability, and height.
• This study provides novel evidence for the optimal Seams technique in burn scar management.
