ABSTRACT
The standard bilateral advancement flaps have had great popularity owing to their advantages in terms of reliability, ease of execution, and good results (1,2). However, the limited sliding capacity of these flaps has always been a problem. These flaps have a random vascularization through the subdermal vascular plexus. They are transferred with a forward movement. The flap can be mobilized up to the limits beyond which too much stretching causes failure of its vascularization (3). To improve this limit, a modification of the flap is described in this chapter. The flap extends the possibilities of coverage in the distal areas, reducing the tensile distress. The shape of the flap has been modified following a geometrical scheme that makes available a greater amount of tissue and reduces tension along the closure.
