[A new method to determine the type of scar-changed tissue]

The mechanical parameters of the skin and scarring tissues were assessed in children aged 3-14 years who had various scar types, by using an ACA apparatus, which measures the propagation rates of superficial acoustic waves in the skin. It was found that the types (atrophic, hypertrophic, keloid) of scars could be significantly differentiated from the value of this parameter. The comparison of clinical and acoustic data shows high (as high as 90%) significance of the latter.
