Auricular Prosthesis (假耳)

Special Topics in Anaplastology: Fabrication of an Auricular Prosthesis

Impression Making

Marking Frankfort horizontal for orientation of prosthesis on defect cast.

Impression Casting

Wax Sculpting

Mold Making

3 part mold with a wedge piece to prevent undercut behind helix.

Intrinsic Coloration & Mold Packing

Flocking – short colored fibers were added for a subtle color change and to mimic vasculature.

Base color – semi-opaque underlying skin tone; commonly identified from underside of the forearm, along the hairline, anterior to the tragus, and at the base of the helix.

Laminar glazes: pink blush, freckling, tan, highlight (cartilage), and shadow.

Trimming & Extrinsic Coloration

Trimming excess flash with scissors and smoothing helical seam with silicone bur.

Color matching for extrinsic coloration.

Extrinsic pigments added to medical adhesive moisture-cure silicone.

Deshine with confectioner sugar to alter the surface geometry of the silicone.

Once cured, rinse the sugar off with water.

Fabrication complete with piercing.
