舌的活动度,大小及其结构对口腔癌手术后的修复是很理想的材料,由于舌接近手术缺损区,又有丰富的血液循环,因而可以立即应用,并可以避免采用多阶段的带蒂皮瓣。在改善口腔功能方面,如伤口立即愈合,吞咽及语言等也大大超过以往的方法。由于舌部丰富的血液循环,舌瓣的成活率很高,舌动脉从后下方穿过舌体沿途分枝直达舌尖部,另外舌的侧枝血管尚来源于舌深动脉,面动脉颏枝,腭动脉的扁桃腺枝。 Tongue activity, size and structure of the postoperative oral cancer repair is a very good material, because the tongue close to the surgical defect area, but also has extensive blood circulation, which can be immediately applied and can avoid the use of multi-stage pedicle Flap. In improving oral function, such as immediate wound healing, swallowing and language, but also greatly exceeded the previous method.

In addition, the collateral vessels of the tongue come from the deep branch of the tongue, Artery of the tonsils.
