The care and treatment of a child with microtia depends on the severity of the case. Some children will need a series of operations, while others might not need any treatment at all.

Though the prospect of your child needing a surgical procedure is worrisome, it’s important to remember that these procedures have excellent success rates.

What surgical treatment is usually used for microtia?

The most common type of operation for microtia we perform at Boston Children’s is called autologous auricular construction. During this operation, specially trained pediatric plastic surgeons will take cartilage from your child’s ribcage and use it to “plant” a new ear on the affected side of the head. The process uses your child’s own tissue, so if the new ear is ever injured it can heal itself just as a natural ear would. Autologous construction is performed when a child is 6 years of age or older. He/she needs to be old enough to have sufficient rib cartilage to “spare”, and 6 years is about the age when the ear on the other side (if applicable) will reach its approximate adult size—so the surgeons can be sure to line up the new ear to match it.

Will my child need further operations as he/she ages?

Yes. Autologous construction usually requires three procedures in total, depending on the type and severity of your child’s microtia. Procedures are typically scheduled six months apart to allow your child time to heal.

First procedure Surgeons remove some cartilage from the ribcage to build a new ear.
Second procedure Surgeons refine and reposition the new earlobe.
Third procedure Surgeons lift the new ear for better alignment and perform “touch-ups” as needed. 

It is possible that your child also may need an operation on the middle or inner ear. In that case, surgeons will perform the procedure after the last operation is done. 

How will my child look after the reconstruction?

While your child’s reconstructed ear will not look exactly like his other ear, it will greatly improve his/her appearance (and will allow practical things like wearing eyeglasses or sunglasses).

Are there alternatives to surgical treatment for microtia?

In general, we recommend autologous construction as the most effective treatment for microtia. It offers children a comfortable new ear that feels natural, facilitates the use of eyewear, boosts self-esteem and improves their quality of life. At the same time, we understand that every child and family is different. Your doctors will work with you to decide on the right option. 

Alternatives to autologous construction include:

  • No treatment You may opt not to have any treatment at all. Talk to your child’s care team for guidance and advice.
  • Ear implant An artificial ear made from synthetic materials can be used instead of cartilage. Advantages include no chest scar and ear construction as early as age three. Disadvantages include a higher complication rate and potential long-term problems compared to autologous construction.
  • Ear prosthesis This type of artificial ear, made from a synthetic material, can be attached to the side of your child’s head with a minimally invasive procedure. Disadvantages include the need for daily care.

What happens if my child has hearing loss related to his/her microtia?

If your child has a hearing problem related to microtia, she/he will be followed by an audiologist (hearing specialist) and an otolaryngologist (ear, nose and throat expert). Together, the team will:

  • monitor the hearing loss with regularly scheduled hearing tests (audiograms)
  • recommend hearing aids and other ways to maximize the use of the remaining hearing • suggest a hearing aid (either worn as a headband or implanted into the bone) in the event of serious hearing loss
  • offer surgery to recreate a missing ear canal (called atresia repair) and improve hearing. Alternatively, a bone anchored hearing aid (BAHA) may be offered.
  • recommend additional language or developmental assessments for your child, as needed
  • direct you to community resources for educational or financial assistance

Timeline of care

  • Infancy: Possible headband hearing aid
  • 6 years of age or older: First stage autologous reconstruction
  • 6 months later: Second stage autologous reconstruction
  • 6 months later: Third stage autologous reconstruction
  • 6 months later: Possible bone anchored hearing aid (BAHA), possible atresia repair
