Therapy for keloids and hypertrophic scars is controversial because of the difficulties in diagnosis and the high recurrence rate after surgery. The Japan Scar Workshop presented the JSW Scar Scale 2011, with which each scar lesion is scored and accordingly classified as a mature scar, hypertrophic scar, or keloid. Here, we applied this scale to our surgically treated scar patients to evaluate its validity to decide treatment plans and predict recurrence rates. Nineteen patients were included in the study (6 males and 13 females). According to the scale, 12 patients were classified with keloids, six with hypertrophic scars, and one with a mature scar. Post-operative irradiation therapy was delivered to ten keloid lesions (83.3%) and one hypertrophic lesion (16.7%). There were six recurrent lesions (two major and four minor recurrences), all of which scored more than 18 points using the scale. These results indicate that the JSW Scar Scale 2011 can be used to diagnose scar lesions in terms of whether to apply post-operative irradiation therapy and to predict recurrence.
