Use of a traction suture loop for subungual glomus tumor excision

Initially, the nail plate is laterally displaced with a mosquito clamp. A longitudinal incision is made in the nail matrix to expose the underlying glomus tumor. After careful dissection and exposure, the needle is inserted through the most superficial portion of the tumor to create the traction loop. Gentle upward traction is applied, providing stable exposure and facilitating dissection from its base. The procedure concludes with the closure of the nail matrix using fine absorbable sutures to preserve nail growth and reduce the risk of dystrophy.首先，使用蚊式止血钳将甲板向外侧牵拉。随后在甲母质处做纵行切口，以暴露下方的血管球瘤。经精细剥离与暴露后，将穿刺针穿过肿瘤最表浅的部分以构建牵引环。随后轻柔向上牵拉，以获得稳定的暴露视野，并便于从肿瘤基底处完成剥离。手术最后以细号可吸收缝线缝合甲母质，以此保留甲板生长功能并降低甲营养不良的发生风险。
