Development and Preliminary Evaluation of A Soft Tissue Microtia Simulator.

Area of Science:

• Medical Simulation
• Plastic Surgery
• Biomedical Engineering

Background:

• Microtia reconstruction training traditionally focuses on framework creation.
• Soft tissue reconstruction in microtia presents significant surgical challenges.
• A dedicated simulation platform for soft tissue microtia reconstruction is needed.

Purpose of the Study:

• To develop and conduct a preliminary evaluation of a high-fidelity soft tissue microtia simulator.
• To assess the anatomical accuracy, realism, and training value of the developed simulator.

Main Methods:

• Utilized 3D modeling software, fused deposition 3D printing, adhesives, silicones, and polyurethane rubbers.
• Created a right lobular-type microtia simulator with skin, subcutaneous tissue, and cartilage components.
• Two expert microtia surgeons performed reconstruction on the simulator and completed a Likert-type questionnaire.

Main Results:

• Surgeons successfully executed critical soft tissue reconstruction steps on the simulator.
• The simulator demonstrated anatomical accuracy and realism.
• Preliminary assessment indicated high value as a training tool for microtia reconstruction.

Conclusions:

• A high-fidelity soft tissue microtia simulator was successfully developed and validated.
• The simulator serves as a valuable platform for training essential microtia reconstruction techniques.
• This tool addresses a critical need in surgical education for microtia repair.
