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.
Now of the two triangles, the isosceles has one form only; the scalene or unequal-sided has an infinite number. The points we occupied respectively formed a scalene triangle. Of triangles there are two kinds; one having the opposite sides equal (isosceles), the other with unequal sides (scalene). On the other hand, triangles can be divided into equilateral, isosceles and scalene, since no other kind of triangle can exist. Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 5 Various. But it is sometime rationall, and to be expressed by a number: yet but in a scalene triangle onely.
