Numerical Evaluation of Scar After Breast Reconstruction with Abdominal Advacement Flap

Popis výsledku v původním jazyce

The treatment of breast cancer has been developed a lot last decade, nevertheless it's still is a considerable social and economical matter in all countries of the world. The choice of the surgery depends on a patient´s protocol and the surgeon´s preferences.The aim of this study is to evaluate the scar loading after breast reconstruction.Methods The mathematical modeling of the sutured skin flap used for breast implant's placing was divided into following two steps. First a material model of the selected silicone implant was identified. Second the mathematical model of the breast and implant was performed. Results The maximal geometrical deviation for anatomical and elliptical implant is on the lower surface of the breast and upper surface of the breast, while in the region of lateral geometry and the area around nipple the agreement is very high. The maximal tension is located in two median stitches. The maximal force reaches 0.025 N. The equivalent Cauchy stress is located around the nipple reaches the value 380 kPa. Conclusion From our results can be seen, that the anatomical and elliptical breast implant didn´t resulted into the same scar loading. The maximal value difference reaches 13.4 % between stress values for these two breast implants. So that the round implant resulted in higher loaded scar than the anatomical one.
