Abstract：
This study aimed to investigate the safety and efficacy of depilation with intense pulsed light (IPL) in congenital microtia patients during their reconstruction treatment. The hairy skin was treated with the M22TM system (Lumenis, German) using a filter of 695 to 1200 mm. A contact prob with a window of 15 cm × 35 mm or 8 cm × 15 mm was used at a radiant setting of 14 to 15 J/cm2 in the non-expander group and 13 to 14 J/cm2 in the expander group, both in a single pulse mode. The efficiency index of hair removal was classified based on the percentage of hair density reduction as excellent (>75%), good (50-75%), fair (25-50%), poor (<25%). The depilation effect was compared between the 2 groups, and any adverse effects were evaluated. A total of 159 patients were included, with 93 patients in the expander group and 66 in the non-expander group. The reduction of the hair density in the expander group after 3 treatments was higher than that in the non-expander group [82.98 (73.47-89.09)% vs 77.84 (71.50-85.34)%; P < .05, Wilcoxon rank-sum test], as well as the efficiency [excellent cases 68 (73.12%) vs 37 (56.06%); P < .05, Chi-square test]. Four cases of folliculitis, 3 cases of blisters, and no instance of expander exposure and cartilage absorption were observed in this study. Hair removal with IPL is a safe and effective photo-epilation method during all stages of ear reconstruction using tissue expander. Depilation in the skin expansion period resulted in better outcomes after 3 treatments, although after 5 treatments no difference between the 2 groups was observed.
摘要：
本研究旨在探讨强脉冲光(IPL)在先天性小耳畸形患者重建治疗过程中脱毛的安全性和有效性。毛状皮肤用M22TM系统治疗(Lumenis，德语）使用695至1200毫米的过滤器。在非扩张器组中在14至15J/cm2的辐射设置和在扩张器组中在13至14J/cm2的辐射设置下使用具有15cm×35mm或8cm×15mm的窗口的接触探针,都是单脉冲模式。脱毛效率指数根据毛发密度降低的百分比分类为优秀(>75%),良好（50-75%），公平（25-50%），差（<25%）。比较两组脱毛效果，并评估任何不良反应。共纳入159名患者，扩张器组93例，非扩张器组66例。3次治疗后扩张剂组的毛发密度降低高于非扩张剂组[82.98（73.47-89.09）％vs77.84（71.50-85.34）％；P<0.05，Wilcoxon秩和检验]，以及效率[优良病例68例（73.12%）对37例（56.06%）；P<.05，卡方检验]。4例毛囊炎，3例水泡，在这项研究中没有观察到扩张器暴露和软骨吸收的实例。在使用组织扩张器进行耳朵重建的所有阶段中，使用IPL进行脱毛是一种安全有效的光脱毛方法。皮肤扩张期脱毛在3次治疗后产生了更好的结果，尽管在5次治疗后，两组之间没有观察到差异。
