The erbium:YAG laser is a popular modality for laser skin resurfacing (LSR). This study was performed to evaluate the safety and efficacy of a new portable Er:YAG laser in the treatment of photo-damaged skin.
Nine patients with skin types I-III were treated for rhytides, large pores, pigmented lesions, lentigines and photo-damage. Small facial areas such as the periorbital area, nose, cheeks, and upper lip were treated with one to six passes at 5-6 J/cm2 with a new portable Er:YAG laser. Topical and local anesthesia was used.
All treated areas showed improvement and, depending upon the number of passes, re-epithelialization was complete within 2-7 days. The intense erythema resolved within 7 days and there was blending of treated and untreated areas within 2 weeks.
The technique of applying a tailored number of 5-6 J/cm2, 300 micros pulses of a new portable Er:YAG laser to small areas appears to be safe and effective. There was minimal discomfort and a high level of patient satisfaction after a relatively short recovery time.
铒钇铝石榴石激光是一种常用于激光皮肤磨削术(LSR)的方式。本研究旨在评估一种新型便携式铒钇铝石榴石激光治疗光损伤皮肤的安全性和有效性。
对9例皮肤类型为I - III型的患者进行治疗,以改善皱纹、毛孔粗大、色素沉着性病变、雀斑和光损伤。使用新型便携式铒钇铝石榴石激光,以5 - 6 J/cm²的能量对眼周区域、鼻子、脸颊和上唇等小面积面部区域进行1至6次照射。采用局部和表面麻醉。
所有治疗区域均有改善,根据照射次数不同,2至7天内创面完全上皮化。强烈的红斑在7天内消退,2周内治疗区域与未治疗区域融合。
对小面积区域应用新型便携式铒钇铝石榴石激光,以5 - 6 J/cm²的能量进行300微秒脉冲、定制次数的照射技术似乎是安全有效的。在相对较短的恢复时间后,不适感极小,患者满意度较高。
