Summary

Facial reconstruction often removes extra tissue. Island pedicle and rhombic flaps conserve the most tissue, improving efficiency in reconstructive surgery.

Area of Science:

  • Plastic Surgery
  • Dermatologic Surgery
  • Surgical Oncology

Background:

  • Facial reconstructive techniques restore appearance after skin cancer removal but often require removing additional healthy tissue (Burow's triangles).
  • Current methods do not regenerate lost tissue, necessitating techniques that manage surrounding tissue for optimal closure.

Purpose of the Study:

  • To quantify and assess the variability of redundant tissue loss in conventional facial reconstruction.
  • To calculate "tissue efficiency" for various reconstructive techniques.

Main Methods:

  • Computer-aided design (CAD) software was used to model standard circular defects.
  • Surface area calculations determined tissue loss for different conventional closure designs.
  • Tissue efficiency was calculated as defect surface area divided by total tissue loss.

Main Results:

  • Island pedicle flaps demonstrated the highest tissue conservation at 78.5%.
  • Rhombic flaps also showed significant tissue conservation, achieving 68.0%.
  • These flap designs are more tissue-conservative than standard linear closure.

Conclusions:

  • Most flap designs significantly improve tissue efficiency compared to linear closure by minimizing overall tissue loss.
  • Modifications to flap designs can further reduce or eliminate additional tissue removal while enhancing flap mobility and tissue recruitment.
