The forehead flap is a dependable option for nasal reconstruction owing to its reliability and anatomic likeness to nasal skin. For patients with low hairlines, the vertical design of the paramedian forehead flap can intrude into the scalp, thus incorporating hair into the nasal reconstruction. The inadequate length of the forehead flap or shift to an oblique design may result in eyebrow elevation and asymmetry. Therefore, laser hair removal (epilation) on the forehead flap has been proposed to improve esthetic results. An alexandrite laser (755 nm, 10 to 20 ms, 18-mm spot size) with a Dynamic Cooling Device (DCD) cooling system was used for hair removal in 22 patients (16 male and 6 female patients) after nasal reconstructions using forehead flaps from December 2011 to September 2016. All patients received cryogen spray cooling laser treatment (CSC-LT). The mean follow-up period was 24 months, with a range between 18 and 50 months. The average duration of treatment was 1.8 months (range, 1-5 months). The energy density ranged from 14 to 18 J/cm with an average of 17.2 J/cm. The number of treatments ranged from 2 to 4 (mean 2.8). Patients had satisfactory esthetic results over 11.1 months (range, 8-18 months). Residual white hairs were observed in 3 patients, and 4 patients had tiny black residual hairs without deteriorating cosmesis. Using an alexandrite laser to remove hair on the forehead is safe and reliable in nasal reconstruction with superior recipient site cosmesis.
额部皮瓣因其可靠性和与鼻皮肤的解剖相似性，是鼻重建的可靠选择。对于发际线低的患者，正中额皮瓣的垂直设计可以侵入头皮，从而将头发纳入鼻重建中。额部皮瓣的长度不足或转为斜设计可能导致眉毛抬高和不对称。因此，已经提出在额部皮瓣上进行激光脱毛（脱毛）以改善美容效果。在 2011 年 12 月至 2016 年 9 月期间，使用带有动态冷却装置（DCD）的 Alexandrite 激光（755nm，10 至 20ms，18mm 光斑大小）对 22 例（16 名男性和 6 名女性）接受额部皮瓣鼻重建后的患者进行了脱毛。所有患者均接受了冷冻喷雾冷却激光治疗（CSC-LT）。平均随访时间为 24 个月，范围为 18 至 50 个月。平均治疗时间为 1.8 个月（范围为 1-5 个月）。能量密度范围为 14 至 18J/cm，平均为 17.2J/cm。治疗次数范围为 2 至 4 次（平均 2.8 次）。在 11.1 个月（8-18 个月）的时间内，患者获得了满意的美容效果。3 例患者观察到残留的白色毛发，4 例患者有细小的黑色残留毛发，但不会影响美容效果。在鼻重建中使用 Alexandrite 激光去除额部毛发是安全可靠的，可获得更好的受区美容效果。
