OBJECTIVES: To demonstrate use of computer aided design and 3D printing in creating simulated costochondral cartilage to practice creation of auricular frameworks. To identify a material that most closely simulates cartilage.
METHODS: The costal cartilage of a free floating rib with adjacent synchondrosis was digitally segmented from a CT scan using medical imaging software. The resulting 3D mesh model was exported to 3D modeling software. A negative model was constructed using mesh Boolean and 3D printed. The resulting mold was filled with vinyl polysiloxane or a mixture of silicone and cornstarch to produce the final model for framework carving. Microtia surgeons rated the models’ carving and suturing characteristics relative to human cartilage on a Likert scale.
RESULTS: An accurate reproduction of patient specific costal cartilage was produced. The composition material produced a texture and firmness similar to human cartilage. Likert ratings are reported.
DISCUSSION: This study demonstrates a low cost, readily reproducible tool to simulate auricular reconstruction. There may be benefit from use of a patient specific costal cartilage model.
