    Summary
    This summary is machine-generated.

    Round breast implants cause higher scar stress than anatomical ones after reconstruction, with maximal tension differences reaching 13.4%. This finding is crucial for surgical planning and patient outcomes.

    Area of Science:

    • Biomedical Engineering
    • Plastic Surgery
    • Oncology

    Background:

    • Breast cancer remains a significant global health and economic challenge.
    • Surgical choices for breast reconstruction vary based on patient and surgeon factors.
    • Evaluating scar stress post-reconstruction is essential for improving outcomes.

    Purpose of the Study:

    • To assess and compare the stress distribution on surgical scars after breast reconstruction using different implant shapes.
    • To determine the impact of anatomical versus round silicone implants on scar tension.

    Main Methods:

    • Developed a mathematical model simulating sutured skin flaps for breast implant placement.
    • Identified the material properties of silicone implants used in the model.
    • Constructed a comprehensive mathematical model of the breast and implant system.

    Main Results:

    • Maximal geometrical deviation observed on the lower and upper breast surfaces.
    • Highest tension localized in median stitches, with maximal force reaching 0.025 N.
    • Peak Cauchy stress equivalent of 380 kPa identified around the nipple area.

    Conclusions:

    • Anatomical and round breast implants generate different levels of scar stress.
    • Round implants result in higher scar loading compared to anatomical implants.
    • A significant difference of up to 13.4% in maximal stress values was noted between implant types.
