Epidermoid cyst (EC) is a common and benign tumor, which can occur anywhere on the skin. Surgical excision is usually considered as the first-line treatment. However, linear scars arising after excision for EC remain a cosmetic problem.
To evaluate the efficacy and safety of EC removal assisted with CO laser fenestration.
All patients diagnosed with EC and treated with CO laser fenestration, content extrusion, and removal of the cyst wall between January 1, 2016, and December 31, 2018, were included in this study. After a follow-up period ranging from 6 to 27 months, scarring, recurrence, complications, and satisfaction were assessed and analyzed.
Forty-three of the 47 patients have been cured by a single operation. The recurrence rate was 8.5%, which was not significantly correlated with tumor sizes or locations. 46.8% of the patients had no obvious scar after treatment. No infections or complications were observed in any of these cases. 89.4% of the patients were satisfied with the effectiveness of the treatment, while 95.7% and 87.2% were satisfied with the comfort and the cosmetic results, respectively.
CO laser fenestration-assisted removal procedure is effective for the treatment of ECs with good aesthetic outcome.
表皮样囊肿（EC）是一种常见的良性肿瘤，可发生于皮肤的任何部位。手术切除通常被认为是一线治疗方法。然而，EC 切除后遗留的线性瘢痕仍然是一个美容问题。
评估 CO2 激光开窗辅助 EC 切除的疗效和安全性。
本研究纳入了 2016 年 1 月 1 日至 2018 年 12 月 31 日期间接受 CO2 激光开窗、内容物挤出和囊肿壁切除治疗的所有 EC 患者。随访 6 至 27 个月后，评估并分析了瘢痕、复发、并发症和满意度。
47 例患者中，43 例经单次手术治愈。复发率为 8.5%，与肿瘤大小或位置无明显相关性。治疗后 46.8%的患者无明显瘢痕。所有患者均未出现感染或并发症。89.4%的患者对治疗效果满意，95.7%和 87.2%的患者对舒适度和美容效果满意。
