The primary presumed advantages of the deep inferior epigastric perforator flap over other muscle-sparing (MS) transverse rectus abdominis myocutaneous flaps are improved functional muscle outcomes and decreased abdominal contour morbidities. purpose this study was to verify viewpoint objectively quantitatively using an animal model.Six rats were used in pilot 40 equally divided into a control group 4 experimental groups (MS0, MS1, MS2, MS3) according amount muscles harvested. At 3 6 weeks, each killed, then, percentage residual thickness compared with side ultimate load at failure wall recorded compared.All survived completely without complications. Regarding side, results suggested MS3 > MS2 ≈ MS1 MS0; concerning wall, showed MS0. (≈: P 0.05; >: < 0.05).According findings study, we advocate use when possible, MS2-transverse can serve as backup anatomy does not meet safety criteria for preservation function.
