A prosthetic ear is an artificial ear that is usually made of silicone from a mould that often uses the opposite ear (or a parent’s ear in bilateral cases) as a template. The prosthesis can either be held onto the head with adhesive or using magnets or clips. The magnetic or clip-on prosthesis requires a surgical procedure to screw studs into the bone on the side of the head.
The prosthetic ear needs to be replaced every few years as the old one wears out. Daily cleaning of the prosthesis and skin around the site is required.
A prosthesis is usually constructed in four steps. The first step is to take an impression of the opposite ear (or a parent’s ear in bilateral cases). Next, a clay sculpture is made of the ear. In step three, the sculpture is moulded and an elastic material is cast to replicate the ear. Finally, the prosthesis is hand painted and tinted to match the surrounding skin.
