Area of Science:

  • Plastic Surgery
  • Microsurgery
  • Surgical Techniques

Background:

  • The sural neurofasciocutaneous flap is a versatile option in reconstructive surgery.
  • Optimizing flap survival necessitates understanding the impact of different pedicle designs on vascular supply and venous drainage.

Purpose of the Study:

  • To evaluate the efficacy of various pedicle configurations for the sural neurofasciocutaneous flap in a rabbit model.
  • To determine the optimal pedicle design that ensures maximum flap survival and viability.

Main Methods:

  • Forty New Zealand rabbits underwent flap elevation with four different pedicle designs: single perforator, fascia, perforator-plus fascia, and in situ suturing.
  • Flap survival rates and central flap blood flow (perfusion units) were assessed at seven days post-operation using laser Doppler flowmetry.

Main Results:

  • The single perforator pedicle flap (Group A) and perforator-plus fascia pedicle flap (Group C) demonstrated significantly higher survival rates (74% and 75%, respectively) and perfusion units compared to the fascia pedicle flap (Group B, 60%).
  • The in situ sutured flap (Group D) showed complete failure (0% survival).
  • Groups A and C exhibited comparable survival and perfusion, indicating robust vascularization and drainage.

Conclusions:

  • The sural neurofasciocutaneous flap elevated on a single perforator pedicle provides a reliable blood supply and adequate venous drainage.
  • This technique represents a superior method for obtaining the sural neurofasciocutaneous flap, ensuring high success rates in reconstructive procedures.
