Summary

This study compared subjective scar assessments using the Vancouver Scar Scale (VSS) with objective viscoelastic measurements. Results showed VSS scores differed significantly from normal skin, but objective measurements were near normal, indicating a disconnect.

Area of Science:

  • Dermatology
  • Biomedical Engineering
  • Wound Healing Research

Background:

  • Scar assessment often relies on subjective scales like the Vancouver Scar Scale (VSS).
  • Objective methods for evaluating scar tissue properties, such as viscoelasticity, offer a complementary approach.
  • Different wound dressings may influence scar development and tissue properties.

Purpose of the Study:

  • To compare subjective scar assessment using the Vancouver Scar Scale (VSS) with objective viscoelastic measurements.
  • To evaluate the effectiveness of different dressings (vaseline gauze, biobrane, occlusive) on scar properties.
  • To investigate the correlation between subjective VSS ratings and objective viscoelastic measurements.

Main Methods:

  • Prospective study design.

  • Donor sites from the thigh were evaluated 0.5 years postoperatively.
  • Subjective scar assessment using the Vancouver Scar Scale (VSS).
  • Objective viscoelastic measurements using the Cutometer (Courage and Khazaka).

    • Main Results:

    • Vancouver Scar Scale (VSS) ratings for donor sites showed significant differences compared to normal skin (F: 2.74, B: 4.25, O: 2.57).
    • Objective viscoelastic measurements by the Cutometer indicated tissue properties near normal compared to uninjured skin.
    • No significant correlation was found between the VSS pliability subscale and Cutometer readings.

    Conclusions:

    • Subjective scar assessment via VSS may not fully reflect objective tissue viscoelastic properties.
    • Objective viscoelastic measurements provide a different perspective on scar healing compared to subjective scales.
    • Further research is needed to reconcile subjective and objective scar evaluation methods.
