Approximately, one in 5000 children are born with auricular malformations (Wu et al. Lasers Med Sci 28(6):1475–82, 2013). The most common deformity, the protruding ears, or “bat ears,” can be a subject of much teasing from schoolmates. In the girls, the bat ears become even more prominent if they tie their hair above the head, say for ballet practice.
