Purpose: Hypertrophic scars after burn wound management remain a difficult problem for many burn surgeons despite of new treatment option is developed. After burn wound healed with scarring or pigmentation, the patient suffer in daily life with the cosmetic results and scar symptoms. Dermastamp? is new treatment modality on burn scar management in our burn center. Dermastamp? is stamp shaped and it contains 0.8 mm or 2.1 mm long multiple stainless steel needles. Dermastamp? was simply pressed down on the scar 3∼4 times and makes 200∼300 holes on 1 cm2 scar area. Dermastamping breaks the dense collagen fiber and fibroblast in the scar tissue and rearranges collagen fiber and fibroblast in the scar tissue.
Methods: The 51 patients were selected. The group consisted of 26 male and 25 female patients. 21 patients were adult and 30 patients were children. Stamping area of the 18 patients was below 25 cm2, 6 patients were in 25 to 100 cm2, and 27 patients were above 100 cm2, stamping area. They received dermastamp? treatment 3 to 23 times in every 1 or 2 weeks interval at least 2 months. The 33 patients received dermastamp? under local anesthesia and other 18 patients received under volatile induction anesthesia. Hypertrophic scar is evaluated with Vancouber Scar Scale (VSS) score by two surgeons and scar height using Sonography (17 patients). And pathologic study (17 patients) was done on volunteer cases.
Results: Clinically improvements with VSS score (1 to 6 points down) were noted in all patients group. Scar height was lowered (0.8 to 3.6 mm) on sonography and pathologic report revealed collagen fiber rearrangement and scar height thinning in examined group.
Conclusion: Microneedling procedure is a effective modality of management on hypertrophic scarring and pigmentation. Microneedling induces collagen fiber rearrangement on scar tissue and thinner the scar height in pathology and improves clinical evaluating with VSS score and patients symptoms.
