Pediatric plastic surgery (many congenital deformities impair physical function as well as aesthetics) is falsely believed to have parts of the body are remade or reformed and children make up roughly 3% of all plastic surgery procedures.
This is a logical prefix, as parts of the body are remade or reformed during most reconstructive and cosmetic surgical procedures. Plastic is a derivative of the Greek word plastikos, which means "to build up" or "to take form".
