Abstract：
UNASSIGNED: Onychomycosis is the most common nail infection, predominantly caused by Trichophyton spp., and is divided into four main types. Confirmatory testing is crucial, but obtaining an adequate sample may be challenging. We suggest the use of carbon dioxide (CO2) laser for painlessly detaching the nail plate during mycological examination and ensuring a sufficient specimen.
UNASSIGNED: We retrospectively enrolled 25 patients with distolateral onychomycosis, treated according to the following protocol: (1) multiple passes of CO2 laser at 10 W in continuous mode along the proximal border of the affected nail plate; (2) the nail plate was gently cut; (3) the nail bed was curetted; (4) subungual debris and plate fragments were collected for KOH test and culture.
UNASSIGNED: The mean visual analog score (VAS) for pain experienced during the procedure was 0.7 (SD: 2.1), indicating that the sampling was relatively painless for the majority of patients. There were no permanent changes observed in the nail unit of any patients during the follow-up visits as a result of using the CO2 laser.
UNASSIGNED: We firmly believe that the use of lasers offers numerous advantages, including ease of use, reduced pain perception, and the ability to target the proximal margin of fungal infections where viable hyphae are significantly represented.

摘要：
■甲癣是最常见的指甲感染，主要由毛癣菌引起。,分为四种主要类型。验证性测试至关重要，但获得足够的样本可能具有挑战性。我们建议在真菌学检查期间使用二氧化碳（CO2）激光无痛地分离指甲板并确保足够的标本。
■我们回顾性纳入了25例远外侧甲癣患者，根据以下方案进行处理:(1)沿着受影响的指甲板的近端边界以连续模式在10W下多次通过CO2激光;(2)轻轻切割指甲板;(3)刮除甲床;(4)收集甲下碎片和板碎片用于KOH测试和培养。
■手术过程中疼痛的平均视觉模拟评分（VAS）为0.7（SD：2.1），表明大多数患者的采样相对无痛。在随访期间，由于使用CO2激光，任何患者的指甲单元均未观察到永久性变化。
■我们坚信激光的使用具有许多优点，包括易用性，减少疼痛感知，以及靶向真菌感染的近端边缘的能力，在那里有明显的活菌丝。
