ABSTRACT
BACKGOUND Pulsed dye laser (PDL) is recommended as a good treatment for scars and keloids. However, there has been no absolute indications and standard laser parameters. Some proposed that only hypertrophic and atrophic/flat scars were effectively treated, but others reported that all scars and even keloids responded well to PDL treatment. OBJECTIVE:
To determine whether 595nm PDL treatment is effective for scars and keloids, and if so, which group responds better to treatment between the atrophic/flat scars group and hypertropic scars/keloids group.METHOD:
Twenty-two patients (skin types III-V) with scars and keloids were treated with 595nm PDL (0.45 or 1.5 msec, 4-8J/cm(2), 7mm spot size). Eleven patients had hypertrophic scars/keloids (6 had hypertropic scars, 5 had keloids), and eleven patients had atrophic/flat scars. After several treatments of each lesion, the results were evaluated by extent of the patient's satisfaction and comparision of pre-and post-laser photography and divided into the four categories excellent, good, fair and poor.RESULTS:
The clinical improvement and patient's satisfaction were better in the atrophic/flat scars group than the hypertrophic scars/keloid group. With keloid potients, the result of treatment were found to be particularly poor.CONCLUSION:
From our results, only atrophic/flat scars respond well to 595nm PDL treatment, and hypertrophic scars and keloids should be excluded from this treatments method.
