Laser resurfacing has become less popular because of its long recovery time, significant discomfort, and potential risks. Microsurfacing employs the use of single-pass erbium:YAG (Er:YAG) "mini peels," which may be performed serially.
The purpose of this study was to evaluate the efficacy and patient acceptance of microresurfacing Er:YAG peels in treating facial photodamage. The variable-pulse Er:YAG system was used and was allowed a comparison of the 0.5- and 4-ms pulse widths.
Six female patients underwent eight microresurfacing peels in a split-face fashion using the 0.5- and 4.0-ms pulse durations of a variable-pulse Er:YAG laser. Patients returned at postoperative Days 3 to 4 and 7 for clinical evaluation and Mexameter measurements.
There were no significant differences in healing or postoperative erythema between the 0.5- and 4-ms pulse durations on postoperative Day 7. The average time to reepithelialization was 3.6 days. In a 1-year postoperative interview, four of six patients said that they would undergo the peel again periodically, and five of six stated they had maintained some level of improvement.
Microresurfacing is an effective and well-tolerated procedure. Benefits include its tolerability under topical anesthesia, limited down time, and high patient satisfaction.
激光表面重塑因恢复时间长、明显不适和潜在风险而不再那么受欢迎。微表面重塑采用单次脉冲铒：钇铝石榴石（Er:YAG）“微型换肤术”，可连续进行。
本研究旨在评估微表面重塑Er:YAG换肤术治疗面部光损伤的疗效和患者接受度。使用了可变脉冲Er:YAG系统，并对0.5毫秒和4毫秒的脉冲宽度进行了比较。
6名女性患者采用可变脉冲Er:YAG激光的0.5毫秒和4.0毫秒脉冲持续时间，以半脸方式接受了8次微表面重塑换肤术。患者在术后第3至4天和第7天返回进行临床评估和皮肤黑色素仪测量。
术后第7天，0.5毫秒和4毫秒脉冲持续时间在愈合或术后红斑方面无显著差异。平均上皮再形成时间为3.6天。在术后1年的随访中，6名患者中有4名表示他们会定期再次接受换肤术，6名患者中有5名表示他们保持了一定程度的改善。
微表面重塑是一种有效且耐受性良好的手术。其优点包括在局部麻醉下的耐受性、停机时间有限以及患者满意度高。
