Microtia, which refers to a small and malformed external ear, occurs with an incidence of 1 to 10 per 10,000 births. Among surgical techniques of microtia repair, autologous reconstruction using costal cartilage is the most widely accepted. Autologous reconstruction using costal cartilage technique involves long-term donor-site pain and discomfort, and the surgeon must have great artistic talent to achieve an esthetic auricle. The new invention utilizes advanced 3D printing, additional biomaterials and cell composition. The method relays on printing a patient-specific mold and then filling the mold with a polymer solution, the mold is then washed leaving a polymer-shaped-ear. The designed mold should enable to control different polymer densities, with stiffer areas in the gentle edges.
- Patient-specific auricles in a fast, precise, and simple manner which results in esthetic results
Applications and Opportunities
- Personalized 3D printed ears for patients with microtia or traumatic injuries.
