A finite element model of the 3D-printed transparent facemask for applying pressure therapy.

Background: Transparent facemask has been widely used for the prevention and treatment of facial hypertrophic scars all over the world. 3D printing has improved the fabrication accuracy of the traditional transparent facemasks. However, the pressure distribution pattern generated by the 3D-printed transparent facemasks has not been thoroughly investigated.

A validation study of scar vascularity and pigmentation assessment using dermoscopy.

Introduction: Vascularity and pigmentation are two important indicators of the maturing status of hypertrophic scars. We used the dermoscope to measure vascularity and pigmentation of hypertrophic scars to examine its validity and reliability.

Materials And Method: Eighteen subjects were assessed using the Vancouver Scar Scale (VSS), spectrocolorimeter and dermoscope.
