The mean observer score of POSAS: vascularity (1.3), pigmentation (1.3), thickness (2.0), relief (1.0), pliability (1.3), surface area (1.3). (B) The patient score of skin graft scar who had Moh's micrographic surgery on dorsum of nose 1 year ago was 22. The observer score was 15.3. The patient score of POSAS: pain (1), itchiness (1), color (5), stiffness (5), thickness (5), irregularity (2). The mean observer score of POSAS: vascularity (1.7), pigmentation (3.0), thickness (3.0), relief (2.3), pliability (3.3), surface area (2.0) (presented with permission patients).
