Progress of anatomic research and clinical application of facial artery perforator flap

Abstract

To summarize the present status and progress of the anatomy researches and clinical application of the facial artery perforator flap (FAPF). The relative researches focused on the anatomy researches and clinical application of FAPF were extensively reviewed, analyzed, and summarized. The facial artery perforator (FAP) has constant anatomy. There are more facial artery perforators in the perioral region, and each FAP has two accompanying veins. Distinguished by inferior mandibular border, the upper and the lower flaps both are used for reconstruction of defects on the face. The most widely-used upper flap was FAPF, which is excellent choice of defects in mid-face. Additionally, angular artery perforator flap and lateral nasal artery perforator flap are becoming more and more popular. While submental artery perforator flap, whose pedicle locates under inferior mandibular border, is most used for reconstruction of lower face. FAPF for face defect repair can achieve good outcomes of function and appearance in clinical application. Based on multiple advantages of good aesthetics and function outcomes, high survival rate, flexible design, and simple operation, FAPF is an optimal choice for defect repair of perioral region and nasal ala. However, Further study is needed to determine whether retaining tissue around the pedicle will affect vein reflux of the flap.
