Microtia is a birth defect in which the external ear is not fully developed. It often occurs with atresia, a condition in which the auditory ear canal is not fully developed, closed or missing, resulting in hearing loss<\/a>. The CDC estimates microtia affects one in every 3800 babies<\/a> born in the U.S.<\/p>\n\n\n\n

There are four types of microtia, ranging from the mildest form (Type One), where the ear retains its shape but is smaller than usual, to the most severe (Type Four), where the external ear is missing. It typically occurs during the first trimester of pregnancy, when the outer ear is being formed.<\/p>\n\n\n\n

The causes of microtia and atresia are unknown, but some theories exist. Some babies have an abnormality in a single gene, causing the defect. The CDC reported findings<\/a> on some factors that have a risk for a baby with microtia.<\/p>\n\n\n\n
