Does any doctor here know if there is a medical term to describe the condition of big ears?

Macrotia: Means enlarged ears. There are other ways ears can be mishapen and these have other names. See this page: http://www.plasticsurgery4u.com/pt_qna_folder/pt_qa_ear_otoplasty.html BTW, my dad's ears were big and stuck out a bit and he tells the story that when he was a kid his mom made him wear his hat so that it compressed his ears, hoping they would flatten. They did not but he grew into them.
