Free Vastus Lateralis Myocutaneous (VLMC) Flap for Reconstruction of Radionecrotic Defect of the Head and Neck

股外側肌游離肌皮瓣重建頭頸部放射性壞死

摘要


放射性壞死是頭頸部腫瘤病人接受術後放射線治療後常見的併發症。這是個難題,不只病人的頭頸部外觀很難看,而且可能有血管爆裂或致死的危險。植皮、局部的皮膚或黏膜皮瓣對於沒接受過放射線治療的病人可能效果很好,但是對於接受過放射線治療的病人卻未必能解決嚴重的傷口問題。從2001年10月到2002年9月,共有11位病人因為接受術後放射線治療引起放射性壞死。這些因為放射線壞死引起大的頭頸部缺陷,都以股外側肌游離肌皮瓣重建,結果都令人滿意。兩個病人術後引起的傷口感染,在清創和換藥之後,也都順利痊癒。對於頭頸部因放射線壞死所造成大的傷口及缺陷,我們認為股外側肌游離肌皮瓣能提供足夠的覆蓋面積,也能對抗容易引起的傷口感染,而且對取皮區的影響也小,是一個值得推薦的重建選擇。

Radionecrosis is a common complication in head and neck cancer patients who received post-operative radiotherapy. It is a difficult problem not only poor head and neck appearance and care but also the risk of vessels rupture and mortality. Skin grafts, local skin, or mucosal flaps that might be perfectly adequate in a non-irradiated patient are unlikely to resolve the problem in a wound that has been previously irradiated or is to undergo adjuvant radiotherapy. From Oct. 2001 to Sep. 2002, eleven patients suffered from radionecrosis after post-operative radiotherapy were included. We used free vastus lateralis myocutaneous flaps in the huge radionecrotic defects of head and neck and got a good result. Two patients with post-operative wound infection healed after debridement and wound dressing. VLMC flap not only can provide enough skin territory to cover the huge wound and defect, but also has the ability to resist wound infection. We commend VLMC flap to reconstruct the radionecrotic defect of head and neck.
