摘要
为了查明以颁下血管为蒂岛状皮瓣的解剖,以便临床设计和应用,在51例成人尸体上,通过显微解剖、染色试验等方法观察了颏下区血供。结果如下:此区由颏下动脉供养,该动脉由面动脉发出,出现率100%。起始处外径为1.75±0.15mm((?)±s),主干长60.0±7.9mm。双侧颏下动脉在中线附近有丰富吻合。以颏下动脉为蒂,颏下区可提供皮瓣的最大面积达130mm×65mm。
To observe the anatomy of the island flap based on the submental vessels for clinical ap- plications,the blood supply in the submental region was studied on 51 cadavers by microsurgical dissec- tion and dye injection.It was found that the suhmental region is supplied by the submental artery,which is a constant branch of the facial artery(100% rate of occurrence).The vessel was 60.0±7.9 mm in length with a diameter of 1.75±0.15 mm((?)±s)at its origin.There were rich anastomoses between submental arteries of both sides.Based on the reliable pedicle,the flap dimension can be as large as 130 mm×65 mm.
