Burn Scar Evaluation Using the Cutometer® MPA 580 in Comparison to "Patient and Observer Scar Assessment Scale" and "Vancouver Scar Scale"

The effect of the "Patient and Observer Scar Assessment Scale" (POSAS) and "Vancouver Scar Scale" (VSS) on patients' quality of life and their correlation with objective scar assessment tools, such as the Cutometer (R), is not fully elucidated. In addition, long-term results of the dermal substitute Matriderm (R) used in combination with split-thickness skin grafting (STSG) remain unclear. We evaluated burn scars of 45 patients at least 2 years postburn injury using the Cutometer (R) MPA 580, the VSS, and the POSAS with three additional questions regarding quality of life and correlated the results. Study groups were: 1) scars following conservative treatment, 2) scars following STSG, and 3) scars following STSG in combination with Matriderm (R). Cutometer (R) measurements demonstrated better elastic qualities in the Matriderm (R) group compared with the STSG group. VSS and extended POSAS were rated best for the conservative group, followed by the STSG group and the Matriderm (R) group. There was a significant correlation between POSAS and VSS, quality of life and the objective Cutometer (R) measurements. Conservatively treated superficial dermal burns do not reach the elastic qualities of healthy skin, and the use of Matriderm (R) significantly improves the long-term elastic qualities of STSG in deep dermal and full-thickness burns 2 years post injury. Results from the VSS and the POSAS correlate with restrictions in the quality of life of patients and also with objective Cutometer (R) measurements and are therefore useful tools in scar evaluation following burn injury.
