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.
本研究旨在探讨强脉冲光（IPL）脱毛在先天性小耳畸形患者重建治疗中的安全性和疗效。使用 M22TM 系统（Lumenis，德国）对有毛发的皮肤进行治疗，滤光片波长为 695 至 1200nm。非扩张器组采用窗口为 15cm×35mm 或 8cm×15mm 的接触探头，辐射设置为 14 至 15J/cm2，单脉冲模式；扩张器组采用窗口为 15cm×35mm 或 8cm×15mm 的接触探头，辐射设置为 13 至 14J/cm2，均采用单脉冲模式。脱毛效率指数根据毛发密度减少的百分比分为优秀（>75%）、良好（50-75%）、一般（25-50%）、差（<25%）。比较两组的脱毛效果，并评估任何不良反应。共纳入 159 例患者，其中扩张器组 93 例，非扩张器组 66 例。扩张器组治疗 3 次后毛发密度减少高于非扩张器组[82.98（73.47-89.09）%比 77.84（71.50-85.34）%；P<0.05，Wilcoxon 秩和检验]，脱毛效率[优例 68 例（73.12%）比 37 例（56.06%）；P<0.05，卡方检验]也较高。本研究中观察到 4 例毛囊炎、3 例水疱，无扩张器外露和软骨吸收。在使用组织扩张器进行耳部重建的所有阶段，使用 IPL 脱毛是一种安全有效的光脱毛方法。在皮肤扩张期脱毛，治疗 3 次后效果更好，但治疗 5 次后两组间无差异。
