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.
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.
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.
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.
The Er:YAG laser plays a role in the treatment of superficial rhytids.
最近的研究表明，脉冲无炭二氧化碳激光在治疗皱纹方面是有效的。然而，这些激光会产生热损伤，有可能延长伤口愈合时间。
在本研究中，我们评估了铒（Er）：钇铝石榴石激光在治疗皱纹中的作用。这种波长为2940nm的激光产生的热损伤很小。
20名患者接受了铒：钇铝石榴石激光治疗。治疗了口周、眶周和前额皱纹。使用了能量在400至800mJ之间变化的脉冲；选择了2.5至5mm的光斑尺寸。在2天、1个月和2个月时对患者进行红斑、愈合时间、改善程度和色素沉着方面的评估。
所有20名患者的皱纹均有改善。上皮再生在4至10天内发生。术后红斑在不到2周内消退。激光治疗后3至8周出现临床改善。
铒：钇铝石榴石激光在治疗浅表皱纹中发挥作用。
