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.
11例肥厚性瘢痕采用不同的氩离子激光技术进行治疗。观察期为0.5至3年。直径2至3毫米的点状凝固区，其间穿插着2毫米长的未治疗瘢痕组织区域，6周后在第二次激光治疗中对这些未治疗区域进行激光照射，已证明这种方法最为成功。以这种方式重复进行激光治疗，直到肥厚性瘢痕充分变平。采用低功率密度和非常短暂的多次间断照射期来控制热效应是有效的。据推测，氩离子激光产生的小面积浅表凝固性坏死会导致后续瘢痕组织向其他方向形成，同时减少胶原蛋白的形成，最终导致肥厚性瘢痕变平。
