Skin needle roller importing triamcinolone acetonide into scar to treat hypertrophic scars

Objective To evaluate the effect of importing triamcinolone acetonide into hypertrophic scars with skin roller needles. Methods Thirty-two cases with burn hypertrophic scar were treated. The skin roller needles were moved back and forth on the hypertrophic scars with triameinolone acetonide dropping on the scar surface at the same time. So the triamcinolone acetonide could be imported into the scar through needles and needle holes. The effect was evaluated as cured, effective, and no effect. The Vancouver Searing Criteria and Visual Analogue Scale was used to assess the scar color, thickness, texture and feeling before and after treatment, as well as at the untreated scar area （control）. Results Thirty-two cases were treated 1-3 times, including 28 cases with cured resuh and 4 cases with effective result. The total effective rate was 100%. The scar color, thickness, texture and feeling was siguificandy different between the scar before and after treatment, or between the treated and untreated scar （P 〈 0. 05 ）. Conclusions Importing triamcinolone acetonide into hypertrophic scars with skin roller needles is effective. It is a new method for the treatment of large hypertrophic scar with medicine.
