2: Treat burn scar using Pinhole method

Introduction: Many patients with scar have various complications and emotional problems. Although many attempts to treat scars have been performed, such as excision of scars, skin grafts, laser abrasion, and silicone products usage, many patients were not satisfied with the cosmetic results of those.

Materials / method: Pinhole method is performed by using carbon dioxide laser, which makes close holes resembling pores that penetrate from the epidermis to the part of the dermis of scar. A 20-year-old female patient with scar on the neck and a 25-year-old female patient with scar on the right forearm after burn injury were presented for the treatment of the burn scar. Each patient was treated with pinhole method using carbon dioxide laser.

Results: A few weeks later from the treatment, the lesion showed relaxation of contracture, reduction of wrinkles, improvement of texture and color compared to the previous lesion.

Conclusion: Treatment of scar with pinhole method can be easily performed and also results in good improvement of scar quality with only few side effects.
