The skin covering a digital mucous cyst is often very thin and is often excised with the cyst. Thus, transfer of a skin flap is needed for the defect. We have developed a proximal nail fold flap technique by which the thin skin covering the cyst can be preserved. We conducted a retrospective study to assess the effectiveness and reliability of this technique for digital mucous cyst excision. The study group comprised 26 patients treated for 28 digital mucous cysts. The flap was elevated on the nail matrix to expose the distal interphalangeal joint capsule. To preserve the skin in cases in which the skin covering the cyst was exceptionally thin, we did not excise the upper part of the cyst wall. Excision of the cyst and stalk was successful in all cases. Additional excision of the joint capsule or osteophyte(s) was achieved in 20 cases and 5 cases, respectively. No flap necrosis, skin defect or nail deformity resulted. Three of the cysts recurred and were treated successfully by reoperation involving the same flap elevation technique. We conclude that the proximal nail fold flap is useful for excision and reliable for wound coverage after digital mucous cyst excision. J. Med. Invest. 63: 278-280, August, 2016.
覆盖指部黏液囊肿的皮肤通常非常薄，常与囊肿一并切除。因此，缺损处需要转移皮瓣。我们开发了一种近端甲襞皮瓣技术，通过该技术可以保留覆盖囊肿的薄皮肤。我们进行了一项回顾性研究，以评估该技术用于指部黏液囊肿切除的有效性和可靠性。研究组包括26例接受治疗的28个指部黏液囊肿患者。在甲床上掀起皮瓣以暴露远侧指间关节囊。为了在覆盖囊肿的皮肤异常薄的情况下保留皮肤，我们没有切除囊肿壁的上部。所有病例囊肿及蒂部切除均成功。分别有20例和5例进行了额外的关节囊或骨赘切除。未出现皮瓣坏死、皮肤缺损或指甲畸形。3例囊肿复发，通过再次手术采用相同的皮瓣掀起技术成功治疗。我们得出结论，近端甲襞皮瓣在指部黏液囊肿切除术中对于切除囊肿有用，且在伤口覆盖方面可靠。《医学调查杂志》63: 278 - 280，2016年8月。
