A Biomechanical Evaluation of Auricular Cartilage Autografts in Orbital Floor Defect Repair.

Objective: Auricular cartilage is used as a surgical implant in the management of orbital floor fractures. However, no specific parameters exist regarding the use/limitations of this potential graft. In order to determine the mechanical efficacy of adult auricular cartilage grafts, a mechanical model was developed and studied for structural threshold size limits.
