Pedicled flaps showed better survival rates than free flaps in rabbits. Cutaneous fluorescence proved effective for predicting flap viability, aiding surgical outcomes.

Area of Science:

  • Plastic Surgery
  • Surgical Research
  • Animal Models

Background:

  • Dorsal flap creation is crucial in reconstructive surgery.
  • Assessing flap viability and predictability is essential for successful outcomes.
  • Comparing pedicled and free flaps, as well as cutaneous and myocutaneous types, is important.

Purpose of the Study:

  • To compare the viability of different types of dorsal flaps in rabbits.
  • To evaluate the predictability of flap viability using subjective and objective tests.
  • To determine the effectiveness of cutaneous fluorescence in predicting flap survival.

Main Methods:

  • Seventy dorsal flaps were created in rabbits, including cutaneous pedicled, cutaneous free, myocutaneous pedicled, and myocutaneous free flaps.

  • Flap viability was assessed using both subjective and objective methods.
  • Cutaneous fluorescence was employed as an objective test for viability prediction.

    • Main Results:

    • Pedicled flaps demonstrated a higher survival rate compared to free flaps.
    • Cutaneous fluorescence was identified as a useful tool for predicting flap viability.
    • The study compared survival rates across 18 cutaneous pedicled, 7 cutaneous free, 23 myocutaneous pedicled, and 22 myocutaneous free flaps.

    Conclusions:

    • Pedicled flaps offer a better survival rate in dorsal flap procedures.
    • Cutaneous fluorescence is a reliable method for predicting flap viability.
    • Objective testing, such as cutaneous fluorescence, enhances the predictability of flap survival in surgical settings.
