Abstract:Endoscopic repair with pedicled mucosal flap has become the main treatment of septal perforation with high success rat. There are many types of mucosal flaps reported. According to whether it has vascular pedicle, the mucosal flap is classified into three main types, i.e. non-vascular, partially preserved vascular and vascular pedicled mucosal flap. At the same time, it can also be divided into advancement, rotation and cross-over mucosal flap based on the way of transfering to the perforation area. In addition, there are many variations in mucosal flap due to different donor location. With special emphases on the strategy of obtaining mucosal flap and the method of transferring mucosal flap, this paper summarizes the above-mentioned repair methods for septal perforation with mucosal flap to promote the clinical application.
