Twelve adult patients with bilateral facial telangiectasias were treated with two yellow light lasers. A section of each involved area was treated with a copper vapor laser and a similar section in the same patient was treated with the flashlamp pumped dye laser.
Both lasers provided satisfactory clearance at 2 and 6 weeks. Treatment was not painless with either laser; however, no patient needed local or general anesthesia. The time taken to treat equivalent areas was similar for both lasers. Postoperative swelling was greater with the flashlamp pumped dye laser than with the copper vapor laser and the time required for healing was longer with the flash-lamp pumped dye laser.
The larger purpuric macules produced post-operatively by the flashlamp pumped dye laser were less cosmetically acceptable to patients when compared with the thin linear crusting produced by the copper vapor laser. Scarring or textural changes were not seen with either laser.
12例双侧面部毛细血管扩张的成年患者接受了两种黄光激光治疗。每个受累区域的一部分用铜蒸气激光治疗,同一患者的类似区域用闪光灯泵浦染料激光治疗。
两种激光在2周和6周时均提供了满意的清除效果。两种激光治疗时均并非无痛;然而,没有患者需要局部或全身麻醉。两种激光治疗同等面积所需的时间相似。闪光灯泵浦染料激光术后肿胀比铜蒸气激光更严重,闪光灯泵浦染料激光愈合所需时间更长。
与铜蒸气激光产生的细线性结痂相比,闪光灯泵浦染料激光术后产生的较大紫癜性斑在美容方面对患者来说更难以接受。两种激光均未出现瘢痕形成或质地改变。
