Auricular Prostheses
Silicone Ear Prostheses
Overview
Auricular prostheses are the most common type of facial prosthesis, and a silicone ear can be made for a patient for a number of reasons, commonly due to cancer resection or congenital differences (Treacher Collins Syndrome, hemifacial microsomia, Goldenhar Syndrome). Bilateral ear, partial ear, and adhesive-retained prostheses can also be made, depending on the complexity of the situation.
Process
When possible, a 3D scan is made of the patient’s opposite anatomy, which is then mirrored and 3D printed to serve as a base model for the new prosthesis. A duplicate is then made in wax and then positioned on the patient to ensure that anatomical accuracy and optimal symmetry are maintained. A custom bar structure is designed and constructed to fit directly on the osseointegrated implants on the patient - this structure serves as the foundation of the prosthesis. A multi-part mold is created from the wax sculpture. A custom palette of pigmented silicones are mixed and painted into the mold, resulting in a perfect duplicate of the wax sculpture, which matches the opposite anatomy. Small clips are used to fasten the prosthesis to the bar structure, allowing for easy placement and removal by the patient.
