A porcine rib cartilage model for practicing ear-framework fabrication

Area of Science:

• Biomedical Engineering
• Surgical Education
• Anatomy

Background:

• Effective surgical training requires accessible, realistic models for in vitro practice.
• Current models may lack sufficient anatomical and tactile fidelity for complex procedures like ear reconstruction.

Purpose of the Study:

• To develop and evaluate a cost-effective surgical training model for total ear reconstruction.
• To utilize porcine rib cartilage as a substitute for human cartilage in surgical simulation.

Main Methods:

• Procurement of porcine rib cartilage from readily available sources.
• Fabrication of costal cartilage into auricular framework components.
• Evaluation of the model's anatomical realism and tactile properties compared to human cartilage.

Main Results:

• Porcine rib cartilage provides a low-cost, accessible material for surgical simulation.
• The model replicates the realistic anatomy and tactile feel of human cartilage.
• Trainees can effectively learn to fabricate stable and aesthetically pleasing auricular frameworks.

Conclusions:

• Porcine rib cartilage is a suitable and advantageous material for total ear reconstruction surgical training models.
• This training model enhances surgical skill acquisition for auricular framework fabrication.
• The model promotes the development of stable and aesthetically superior ear reconstructions.
