Microtia: Background Info and Treatment Options

Type III microtia

Complete absence of the canal with a small peanut-shaped remnant of pinna and lobule.  Below is a child before and after his one stage surgery

Type IV microtia (Anotia)

 Complete absence of the ear canal with only a small bleb as an ear remnant.  Below is a patient with anotia.

Things to do once you learn your child has microtia atresia

If you have a new baby with microtia atresia you might feel a little overwhelmed. Some children are born in communities where their physicians are not knowledgeable about microtia atresia and are unable to provide adequate information or suggest appropriate referrals and tests. We are here to help!

*The first thing to do is to talk to your pediatrician about an echocardiogram or renal ultrasound. The ears develop in utero at approximately 5 to 6 weeks gestation which is the same time that the heart and kidneys are developing. These simple tests are very easy to do and are relatively inexpensive.

*Second, your child’s hearing needs to be tested. If your child has unilateral (one sided) microtia atresia, hearing in the normal appearing ear may also be compromised.

*Third, ask your pediatrician for a referral to an otolaryngologist (ENT or ear nose and throat specialist). This professional will help to ensure the health of your child's normal ear. It is important to maintain the health of your child’s normal ear and avoid potential hearing loss associated with undiagnosed inner ear infections (otitis media) which might require eardrum drainage tubes to be placed (tympanostomy tubes).

*Your otolaryngologist can also provide a prescription for a bone conducting hearing device with soft band. This device will enhance speech development and help stimulate the part of your child’s brain that processes sound (auditory cortex).

Some physicians will want to order a temporal bone CT Scan for your infant to obtain information about the anatomy of the inner ear on the side with the microtia.  Scans at this age often do not provide adequate information because the anatomy is small and still developing and the scan often needs to be repeated later. We prefer to postpone the temporal bone CT scan until approximately five years of age. At this age, you child will be old enough for you to consider hearing restoration options.  Dr. Griffiths can reconstruct your child’s microtia at the same time that the hearing restoration surgery is performed (aural atresia repair).

What options are available for reconstructing Microtia-Anotia?

Type I microtia can often be reconstructed with an otoplasty. Type II requires a reconstruction of the upper half of the ear. Type III and type IV require complete ear reconstruction.

Options for microtia reconstruction  include a prosthesis, a MEDPOR polyethylene plastic ear framework covered by living tissue, or a living cartilaginous RIB GRAFT carved into an ear framework covered by living tissue.

Old Classification for Microtia Reconstruction Options

1. Do nothing
2. Auricular prosthesis
3. Rib graft technique
4. Medpor technique

Dr. Griffiths performs an ear reconstruction technique that does not fit into the common classification options listed above so he proposes a new classification system.

New Classification for Microtia Reconstruction Options

1. Do nothing
2. Auricular prosthesis
3. Surgical reconstruction
   •  Rib graft multi-stage technique
   • Medpor technique
   • Dr. Griffiths One stage technique
     1. Rib graft framework
     2. Medpor framework
     3. Canalplasty (atresia repair) at the same time as the Microtia reconstruction

One-Stage Microtia Reconstruction

Dr. Griffiths can reconstruct an entire ear in ONE operation utilizing either Rib Cartilage or Medpor.

Ear Framework Options

To reconstruct an external ear surgically, a framework material must be selected that can withstand the contractile forces of the overlying skin and fascia. The two most widely used options include the patient’s own living cartilage (rib graft) or polyethylene plastic implant (MEDPOR™).
