This study introduces a novel porcine model for perforator dissection practice. This reproducible simulation offers five consistent perforator flaps per side, aiding surgical skill development.

Area of Science:

  • Surgical Education
  • Anatomical Simulation

Background:

  • Perforator dissection presents a significant technical challenge with a steep learning curve.
  • Minimizing inadvertent perforator damage requires extensive practice and specialized tissue-handling techniques.
  • A lack of realistic simulation models for perforator dissection exists.

Purpose of the Study:

  • To present a novel porcine training model for perforator dissection.
  • To establish a reproducible simulation that mimics human perforators in size and course.

Main Methods:

  • Five fresh cadaveric pigs were utilized for the study.
  • Ten perforators (five per side) were dissected by a single surgeon.
  • Perforator length, intramuscular course, ease of dissection, and surgical similarity were evaluated.

Main Results:

  • Five consistent perforators were identified bilaterally in each pig.
  • Perforators were located in the neck, anterior flank, posterior flank, rectus, and hindlimb.
  • Fasciocutaneous perforators with an average intramuscular course of 2.5 cm were noted.

Conclusions:

  • The described porcine model provides five easily replicable perforators.
  • This model is suitable for simulation and practice of perforator dissection techniques.
