Lip expansion is an old procedure used by some ethnic groups to follow traditions of their ancestry. Medically speaking since the beginning of the XIXth century, various devices have been designed for distending the angles of the mouth in order to recreate the normal width of the mouth aperture. In the recent years, thanks to the development and refinements of new flaps, expanding the lips is rarely necessary. In proper indications however, specially in the vermillon border, lip expansion remains a good indication.
唇部扩张术是一些族群沿袭其祖先传统所采用的一种古老手术。从医学角度来讲，自19世纪初以来，人们设计了各种器械用于撑开嘴角，以恢复正常的口角宽度。近年来，由于新型皮瓣的发展和改进，唇部扩张很少有必要进行。然而，在适当的适应症中，特别是在唇红缘，唇部扩张仍然是一个很好的适应症。
