To compare the postoperative outcome among different types of platysma myocutaneous flaps by reviewing 54 cases.
From 1984 to 2004, 54 patients with oral cancer underwent immediate reconstruction of intraoral defects using the platysma myocutaneous flaps. In 54 cases, 12 cases were transversal platysma myocutaneous flaps and the other 42 cases were vertical platysma myocutaneous flaps. In these 42 cases, 26 cases preserved facial artery and vein yet 16 cases didn't preserve them. The survival condition of these flaps were compared.
In the 12 cases of transversal platysma myocutaneous flaps, 10 cases survived totally and 2 cases had partial necrosis. In the 26 cases of vertical platysma myocutaneous flaps preserved facial artery and vein, 23 cases survived completely and 3 cases had partial necrosis. However, in the 16 cases of vertical platysma myocutaneous flaps in that facial artery and veins were not preserved, 10 cases survived completely, whereas 4 cases had partial necrosis and 2 cases had complete necrosis.
The survival rates of platysma myocutaneous flaps that didn't preserve facial artery and vein were low. Its clinical use should be prudent.
通过回顾54例病例比较不同类型颈阔肌肌皮瓣的术后效果。
1984年至2004年，54例口腔癌患者采用颈阔肌肌皮瓣即刻修复口腔内缺损。54例中，12例为横行颈阔肌肌皮瓣，另外42例为纵行颈阔肌肌皮瓣。在这42例纵行颈阔肌肌皮瓣中，26例保留了面动静脉，16例未保留。比较这些皮瓣的存活情况。
12例横行颈阔肌肌皮瓣中，10例完全存活，2例部分坏死。26例保留面动静脉的纵行颈阔肌肌皮瓣中，23例完全存活，3例部分坏死。然而，16例未保留面动静脉的纵行颈阔肌肌皮瓣中，10例完全存活，4例部分坏死，2例完全坏死。
未保留面动静脉的颈阔肌肌皮瓣存活率较低。临床应用时应谨慎。
