Yes, my oldest son has this. He is missing a crease in his ear, so his right ear is very floppy. I lovingly refer to it as his puppy ear, since he looked like a little puppy when he was a baby with his floppy ear. Luckily, his hearing is fine. Our ped did have a renal u/s done to make sure there were not renal problems (in utereo, the ears and kidneys develop at the same time, so if there is a problem with one, they usually check the other to make sure everything is ok). His kidneys are fine too. It turns out it runs in my dad's side of the family. His aunt has TWO ears that are like this and we never noticed until she saw my son and said, "oh, he has my ears." We were like, "huh?" So, I think in our case, it was genetic. Now that he is older, and his hair is shaggier, you don't notice it as much, but as a baby, it was really obvious. I now notice other ppl with this condition more easily, I guess I am more aware of it. My mil and my DH want my son to get plastic surgery done to get it fixed. The doctor said they do it around five yrs old, so they don't get teased at school. I'm not sure if I want him to get plastic surgery or not, but I know that some children (myself being one of them) are VERY sensitive about their looks and looking different. So, we will see what happens. So far he has not noticed his ear is different. Our insurance is supposed to cover congenital issues, so it *should* be covered by our insurance if we go the plastic surgery route. I'm not crazy about any type of surgery, so hope to avoid this route, but if he wants to get it done, I will not stop him from doing it.
