The Vacanti mouse was a laboratory mouse that had what looked like a human ear grown on its back. The "ear" was actually an ear-shaped cartilage structure grown by seeding cow cartilage cells into a biodegradable ear-shaped mold and then implanted under the skin of the mouse; then the cartilage naturally grew by itself.

The ear is built to function like a "conveyor belt" by sloughing off dead skin and earwax that naturally pushes its way out. This system tends to work well without much need for assistance.
Clint Eastwood, who has an extreme form of attached ear lobe.. Earlobes average about 2 centimeters long, and elongate slightly with age. [7] Although the "free" vs. "attached" appearance of earlobes is often presented as an example of a simple "one gene – two alleles" Mendelian trait in humans, earlobes do not all fall neatly into either category; there is a continuous range from one ...
