Coverage of Scapular Exposure in High-voltage Electric Burns with Trapezius Myocutaneous Flap-A Report of Two Cases

高伏特電傷合併肩胛骨外露之斜方肌皮瓣的應用-病例報告

摘要


高伏特電傷往往導致深部組織壞死,尤其是在上背部缺損合併肩胛骨外露,對整形重建外科醫生來說更是一種挑戰。確定壞死組織範圍早期擴創,並且以斜方肌皮瓣來重建缺損,如此除了可通防止因骨骼暴露過久的壞死可能,並可增加受傷部位的血液循環及組織覆蓋,對維持肩部運動功能,有著莫大的貢獻。本文將討論兩個因高伏特電傷合併孤傷病患背部缺損及肩胛骨外露以斜方肌皮瓣來重建成功之案例,並討論斜方肌及其臨床之應用和治療。

The pathway of current in electrical burn patient is unpredictable, and high-voltage electrical burns usually cause progressive deep soft-tissue damage. After forced fluid resuscitation to stabilize the vital signs, a surgical plan should be initiated as soon as possible. We presented two individuals sustained high-voltage electrical burns and the consequent complication of scapular bone exposure of about 8 cm in diameter. We designed an early surgical procedure of a myocutaneous trapezius flap transferring to the lesion site after initial biological dressing with porcine skin. Satisfactory functional results were obtained, with no post-operative complications and a normal range of arm abduction motion at follow-up at more than three years.
