One segment had a patient that had either their ear cut off...or they were born without one. I cannot remember...but that doesn't matter. The point is...they placed a model of an ear under the guy's arm..just like your picture. After some time....they removed that mould with the patients own skin covering it...and attached it to his head.
The end result was a small scar on his arm...and an ear back on the guy's head.
So this guy is just growing himself spare body parts? Interesting.
