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.
In triangle ABC below, all sides are 12 feet making triangle ABC equilateral. Classification of Triangles. Triangles may be classified by. (A) their sides. (B) their angles. A scalene triangle has 3 different sides. An isosceles triangle has two equal sides and one side that is not equal. An equilateral triangle has 3 equal sides. In an acute triangle, all of the angles will measure less than 90 degrees.
