Current advice on the design of dorsal tongue flaps is conflicting because of insufficient understanding of the blood supply. A detailed study of the vascular anatomy shows that the dorsal mucosa has a distinctive vascular pattern that commends the choice of a posteriorly-based midline flap for closure of defects in the soft palate and posterior part of the hard palate. More anterior defects are more easily closed with an anteriorly-based midline flap.
目前关于舌背瓣设计的建议相互矛盾，原因是对血液供应的了解不足。对血管解剖结构的详细研究表明，舌背黏膜具有独特的血管模式，这使得选择以后方为蒂的中线瓣来闭合软腭和硬腭后部的缺损成为一种明智之选。更靠前的缺损用以前方为蒂的中线瓣更容易闭合。
