This 3D model illustrates an othematoma (auricular hematoma), showing a subperichondrial accumulation of blood following blunt trauma to the ear. The visualization highlights the localized fluctuant swelling where the perichondrium is stripped from the underlying cartilage. By demonstrating this vascular disruption, the model provides a crucial clinical reference for understanding the risk of ischemic cartilage necrosis and the development of a permanent "cauliflower ear" deformity if not promptly drained.
