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.
There are many different types of triangles and some of them actually overlap. If we talk about an Equiangular triangle, we're talking about a triangle where the three angles are all congruent to each other and since the sum of these angles is 180, 180 divided by 3 means that each of these angles measures 60 degrees. An equilateral triangle means that the three sides of your triangle are all congruent.
