Microtia literally means "small ear." This term is applied to anyone who has a smaller, or absent ear (although technically speaking, the absence of any ear remnant is referred to as "anotia").

Microtia occurs in approximately 1:6000 births. For some reason (currently unknown), microtia occurs more often on the right side than the left. This condition can also affect both ears.

Any child born with microtia should be evaluated at a craniofacial center to rule out other conditions. For example, children born with microtia on one side may have a condition called Hemifacial Microsomia (see the section on Hemifacial Microsomia). Children who have both ears affected might have Treacher Collins syndrome or Bifacial Microsomia.

Can my child still hear out of this ear?
