The rectus abdominis flap is favored for this application because of its ease of harvest and reliability. It has been used extensively as both a pedicled and free flap for breast reconstruction. It can be harvested as a muscle-only flap or as a myocutaneous flap.lthough not optimal for small or shallow defects, the rectus flap provides the reconstructive surgeon with an excellent option to reconstruct large defects. This flap is most commonly used for glossectomy defects, orbital/maxillary defects, and (as a muscle-only flap) skull base reconstruction.
Types of triangles based on their sides. 1  An EQUILATERAL triangle has all three sides the same length. 2  An ISOSCELES triangle has two sides with the same length. 3  A SCALENE triangle has all three sides different lengths.
Triangles can also be classified according to the number of congruent sides. The. slashes on the sides of a triangle mean those sides are congruent. 10. Like the right triangle, the parts of an isosceles triangle have. special names. The congruent sides are called legs. The angle. formed by the legs is the vertex angle, and the other two. angles are base angles. The base is the side opposite the vertex. angle.
