Palatal mucosal grafts are used to provide bulk and improve the contour of lip defects. Since the palatal grafts are markedly different in color, they must be placed behind the wet-dry mucosal line so that they cannot be easily seen at conversational distances. The contrast with the red vermilion is too great for this graft to be used as a cosmetic lip substitute, but when the graft is used as a living tissue expander in the posterior position, it improves subtle lip contours.
腭黏膜移植物用于增加唇部缺损的组织量并改善其外形。由于腭部移植物的颜色与唇部明显不同，因此必须置于干湿黏膜交界线之后，这样在正常交谈距离下不容易被看到。这种移植物与红色唇红的对比度太大，不适合用作唇部的美容替代物，但当将其作为活体组织扩张器置于唇部后方时，可改善唇部的细微外形。
