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.
Scalene. Another type of triangle which can be either isosceles or scalene is a right triangle. A right triangle is a triangle where one of the angles is 90Âº. A right triangle cannot be an equilateral triangle because all of the angles in an equilateral triangle are 60Âº. There are also two other designations of triangles, acute and obtuse. Acute triangles are triangles where all three angles are less than 90Âº.
