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.
For equilateral triangles, which are a specific type of acute triangles whose angles all have the same measurements, consists of three 60 degree angles and equal length segments on each side of the figure, but for all triangles, the internal measurements of the angles always add up to 180 degrees, so if one angle's measurement is known, it's typically relatively simple to discover the other missing angle measurements.
