What is Microtia?

Microtia is an incompletely formed ear. It ranges in severity from a bump of tissue to a partially formed ear. In most cases, only one ear is affected. In that case, it is called Unilateral Microtia. If both ears are affected, it is called Bilateral Microtia. Unilateral Microtia occurs in 1 out of 8,000 births and Bilateral Microtia occurs in 1 out of 25,000 births.

Why did this happen?

At this time, no one knows why Microtia occurs; however, there is nothing to suggest that the mother's actions during pregnancy caused the Microtia. Further research is necessary to determine the exact cause.

Will this happen to other children I have in the future?

The possibility of passing microtia on to another child is believed to be less than 6%.

What kinds of problems could my child have?

  • In addition to the physical characteristics, your child may have some or all of these problems:

  • About a 40% reduction of hearing in the affected ear

  • Problems locating the direction from which a sound comes

  • Ear infections

Will my child need surgery?

Your child will either require reconstructive surgery to rebuild the outer ear or he/she may wish to wear a prosthesis. There are several types of prostheses and ear implants that are currently available. We suggest gathering information about all the options and visiting with others who have chosen different options. The choices are increasing every year, so try to keep up with all of the current research. If you choose reconstructive surgery, it is a 3 to 4 step process, usually done two to three months apart. Surgical procedures usually begin around 6 years of age, because the ear is 90% of its adult size, so it is easier to determine the size of the ear that must be made.

  • Portions of ribs 5, 6, 7, and 8 are carved into the shape of the external ear

  • The ear is then grafted into place and the overlying skin is draped onto the graft

  • Other operations may be needed to rotate the lobule and possibly to reposition the cartilage framework into it's final position

How do I get help for my child?

Your child should be treated by a qualified craniofacial medical team at a craniofacial center. Currently, FACES has information on many of these teams. This is by no means a comprehensive list of all the craniofacial teams; however, not all of the centers perform microtia surgery. Please contact FACES for details.
