Laser skin resurfacing with erbium-doped yttrium aluminum garnet (Er:YAG) lasers is a newer alternative to CO2 laser treatment, and was developed to reduce common complications. Although Er:YAG lasers have been available for years, safety parameters for efficacious resurfacing with these devices have not previously been available.
The aim of this study was to utilize one practice's laser treatment settings and outcomes data to identify complication rates for various energies and areas of the face and to offer safe energy/depth parameters for treating each area.
A retrospective chart review was performed for full-field confluent laser resurfacing patients treated with a Sciton Contour Tunable Resurfacing Er:YAG laser by the senior author. The data were retroactively analyzed with a time range of 8 years (January 2007-December 2015).
The overall complication rate for MicroLaserPeels (ablation of 50 µm or less) was 10.1% (20 of 198 treatments) and the rate for deep resurfacing treatments was 26.5% (71 of 268 cases). In MicroLaserPeel treatments the cheek area had the highest complication rate, followed by the forehead, nose, perioral, and eyelid areas, in that order (complication rate range, 0%-9.1%). In deep resurfacing treatments the perioral area had the highest complication rate, 38.6% of 145 cases. This was followed by the lids, cheek, nose, and forehead, in that order (complication rate range, 15.2%-20.9%). There is a correlation between increased depth of ablation and increased rate of complication.
The study confirmed the efficacy of Er:YAG resurfacing and provides guidance for a safer approach to excellent outcomes.
铒雅铬石榴石(Er:YAG)激光皮肤重塑是 CO2 激光治疗的一种新选择,旨在减少常见的并发症。虽然 Er:YAG 激光已经问世多年,但这些设备进行有效重塑的安全参数以前并未公布。
本研究旨在利用一家机构的激光治疗设置和结果数据,确定不同能量和面部区域的并发症发生率,并为每个区域提供安全的能量/深度参数。
对由资深作者使用 Sciton Contour Tunable Resurfacing Er:YAG 激光对全脸融合性激光换肤患者进行的回顾性图表审查进行了研究。数据以 8 年的时间范围(2007 年 1 月至 2015 年 12 月)进行了回顾性分析。
微激光磨皮(消融 50 µm 或以下)的总体并发症发生率为 10.1%(198 次治疗中的 20 次),深度换肤治疗的发生率为 26.5%(268 例中的 71 例)。在微激光磨皮治疗中,颊区的并发症发生率最高,其次是额部、鼻部、口周和眼睑区,依次为(并发症发生率范围,0%-9.1%)。在深度换肤治疗中,口周区的并发症发生率最高,为 145 例中的 38.6%。其次是眼睑、颊部、鼻部和额部,依次为(并发症发生率范围,15.2%-20.9%)。消融深度越深,并发症发生率越高。
该研究证实了 Er:YAG 重塑的疗效,并为更安全的方法提供了卓越的结果指导。
