Abstract

BACKGROUND

Modern skin resurfacing began with wire brush surgery. The short-pulse carbon dioxide (CO2) lasers provide an alternative approach for facial rejuvenation. However, the potential for the same complications exist.

OBJECTIVES

To review the more common complications, the reasons for their development, and their possible avoidance.

METHODS

After pre-op evaluation and skin conditioning, a protocol for resurfacing was followed with standardized settings on the Ultrapulse CO2 laser. On the glabrous skin 300 mJ of energy and 60 W of power were used. On the eyelid skin the settings were reduced to 250 mJ and 50 W. After three passes with the Computer Pattern Generator (CPG), a semi-occlusive dressing was applied for the first 5 days after surgery. Then, a bland petrolatum ointment was applied for an additional 5 days. Finally, a moisturizer with sunscreen or a bleaching cream was used.

RESULTS

It was possible at these energy fluences to avoid excessive collagen denaturation and to facilitate wound healing with occlusive dressing. However, complications still occurred. Examples of these are presented in detail.

CONCLUSION

Complications can be minimized with patient education, using optimal laser settings, applying occlusive dressings, and recognizing pending problems early.

摘要

背景

现代皮肤磨削术始于钢丝刷手术。短脉冲二氧化碳（CO2）激光为面部年轻化提供了一种替代方法。然而，同样的并发症仍有可能发生。

目的

回顾更常见的并发症、其发生原因及可能的避免方法。

方法

在术前评估和皮肤预处理后，按照方案使用超脉冲CO2激光进行标准化参数的皮肤磨削术。在无毛皮肤上使用能量300 mJ、功率60 W。在眼睑皮肤上，参数降至250 mJ和50 W。使用计算机图形发生器（CPG）进行三次扫描后，术后前5天应用半封闭敷料。然后，再涂抹温和的凡士林软膏5天。最后，使用含有防晒成分的保湿霜或美白霜。
