[Utilization potential of the CO2-laser in dermal changes]

44 patients with various cutaneous lesions including 18 tattoos, 13 hypertrophic scars or keloids, 4 xanthelasmas, 4 capillary haemangiomas, and 5 other benign cutaneous lesions were treated by CO2-Laser. 28 of these patients were reexamined after a follow-up period of three to four years. Good results were achieved with the CO2-Laser in the treatment of tattoos, xanthelasmas, and haemangiomas. Satisfactory results were obtained in one patient with peri-ungual Koenen-tumors and in two patients with perianal condylomas. Keloids and plantar warts recurred after an initial improvement. The attempts to remove hypertrophic scars did not bring the desired results. In four cases a superficial local wound infection led to a delayed healing process together with an aesthetically unsatisfying final appearance. CO2-Laser treatment brings certain advantages in selected cases where traditional techniques of plastic surgery have a higher complication rate and are additionally a greater burden for the patient. Particularly larger tattoos, multiple xanthelasmas, and capillary haemangiomas are successfully removed with the CO2-Laser, despite the time consuming method for the attending physician.
