title: [Flattening of hypertrophic scars by punctiform argon ion laser coagulation in several sessions].
abstract: 11 hypertrophic scars were treated by different argon ion laser techniques. The observation period is 0.5-3 years. Punctiform coagulation zones of 2-3 mm diameter, interspersed by untreated areas of scar tissue of 2 mm length, which are by lasered 6 weeks later in a second laser session, has proved most successful. Laser sessions are repeated in this manner until sufficient flattening of the hypertrophic scar is achieved. A low power density and very brief multiple interrupted radiation periods for controlling the thermal effect are useful. It is assumed that small superficial coagulation necroses produced by the argon ion laser will result in subsequent scar tissue being formed in other directions while decreasing the collagen formation, eventually resulting in flattening of the hypertrophic scar.
