Scar width
scar width is measure by standard photo with ruler
Time frame: through study completion, an average of 1 year
Hypertrophic scar rate
The onset of hypertrophic scar will be documented in the time of follow-up. The red and stiffness scar which higher than the surrounding skin surface will be considered as hypertrophic scar.
Time frame: through study completion, an average of 1 year
Patient and observer scar assessment scale score
Subscale 1: observer scar assessment scale (score range 5-50), the score 50 is considered as the worse outcome. Subscale 2: patient scar assessment scale (score range 5-50), the score 50 is considered as the worse outcome.
Time frame: through study completion, an average of 1 year
Vancouver Scar Scale
total score range from 0 to 14, the score14 is considered as the worse outcome
Time frame: through study completion, an average of 1 year
Relative side effect
The relative side effect will be documented in each time of follow-up.
