This study presents a novel ex vivo chicken leg model for perforator flap dissection training. This affordable and reproducible model offers consistent perforators for surgical skill development.

Area of Science:

  • Surgical Anatomy
  • Medical Education Models
  • Microsurgery Training

Background:

  • Perforator flap dissection training traditionally uses live animals.
  • A need exists for described ex vivo models for this surgical technique.
  • This study addresses the lack of nonliving models for perforator flap training.

Purpose of the Study:

  • To introduce a novel nonliving model for perforator flap dissection.
  • To utilize a constant perforator found in the chicken leg for training.
  • To provide an affordable and reproducible training alternative.

Main Methods:

  • Utilized 15 chicken legs for anatomical dissection.
  • Employed ink injection to identify the perforator vessels.
  • Raised perforator-based flaps in four specimens for advanced training.
Keywords:

Main Results:

  • Identified a constant intramuscular perforator with a median length of 5.7 cm.
  • Measured median proximal and distal vessel diameters at 0.93 mm and 0.4 mm, respectively.
  • Achieved a median dissection time of 77.5 minutes.

Conclusions:

  • Introduced a novel ex vivo model for intramuscular perforator flap dissection.
  • The chicken leg model is affordable, reproducible, and effective for training.
  • Consistent perforator anatomy and suitable vessel size make this model valuable for surgical education.
