Area of Science:

Plastic Surgery
Surgical Training

Background:

Cartilage framework fabrication is crucial for successful total ear reconstruction.
Training programs can significantly improve novice clinicians' skills in cartilage manipulation and aesthetic judgment.
Current training methods may lack standardized approaches for developing these specific skills.

Purpose of the Study:

To design and evaluate a novel two-stage training program for total ear reconstruction.
To enhance trainees' cartilage framework fabrication techniques.
To improve trainees' cosmetic cognition related to ear reconstruction.

Main Methods:

A two-stage training program was developed using 3D-printed silicone models and porcine rib cartilage.
Stage one involved observation and practice on silicone models.
Stage two involved fabrication using porcine cartilage, followed by simulation of skin coverage.

Main Results:

All trainees successfully fabricated an ear-shaped cartilage framework after completing the program.
The training program led to a measurable improvement in trainees' cosmetic cognition regarding ear anatomy and aesthetics.
The simulation of skin coverage provided a realistic practice environment.

Conclusions:

The developed two-stage training program effectively improves cartilage carving techniques and cosmetic cognition for ear reconstruction.
This program serves as a valuable tool for training, practice, and teaching in the fabrication of cartilage frameworks for total ear reconstruction.
The use of 3D-printed models and porcine cartilage offers a reproducible and accessible training method.
