背景最近的研究表明，脉冲无炭二氧化碳激光是有效的治疗皱纹。然而，这些激光会产生热损伤，可能会延长伤口愈合时间。在这项研究中，我们评估了铒（Er）：YAG激光在治疗皱纹的作用。这种波长为2940 nm的激光几乎不产生热损伤。方法. 20例患者接受Er：YAG激光治疗。口周，眶周，前额皱纹进行了治疗。使用400和800 mJ之间变化的脉冲能量。选择2.5和5 mm之间的光斑尺寸。在2天、1个月和2个月时对患者的红斑、愈合时间、改善程度和色素沉着进行评价。所有20例患者的皱纹均得到改善。上皮再生发生在4至10天之间。术后血肿在2周内消退。激光治疗后3 ~ 8周临床症状改善。Er：YAG激光在治疗中发挥作用。表面皱纹(C)1997年由美国皮肤外科学会，Inc.
BACKGROUND. Recent studies have shown that pulsed char-free carbon dioxide lasers are effective in the treatment of rhytids. However, these lasers produce thermal damage with the potential for prolonged wound healing.OBJECTIVE. In this study we evaluated the role of the erbium (Er):YAG laser in the treatment of rhytids. This laser, with a wavelength of 2940 nm, produces little thermal damage. METHODS. Twenty patients were treated with the Er:YAG laser. Perioral, periorbital, and forehead rhytids were treated. Pulsed of energy varying between 400 and 800 mJ were used. spot sizes between 2.5 and 5 mm were chosen. Patients were evaluated at 2 days, 1 month, and 2 months for erythema, time of healing, degree of improvement, and pigmentary charges.RESULTs. All 20 patients showed improvement of their rhytids. Reepitheliation occurred between 4 and 10 days. Postoperative of eythema resolved in less than 2 weeks. Clinical improvement occurred between 3 and 8 weeks after laser treatment.CONCLUSION. The Er:YAG laser plays a role in the treatment of. superficial rhytids. (C) 1997 by the American Society for Dermatologic Surgery, Inc.
