Microtia is a birth defect where the child's ear is underdeveloped or undeveloped. The condition occurs in about one in every 6, 000 infants, and it is shown to affect more boys than girls. The condition affects the outside of the ear; however, it doesn't interfere with the person's hearing ability.
