Microtia
Does your child have microtia, a condition in which their outer ear did not develop properly during pregnancy?
The Congenital Ear Institute offers surgical and nonsurgical options to improve your child's hearing and the appearance of their ear.
Our San Antonio, TX, practice treats microtia patients from all over the world. We can help your child, too.
What Is Microtia?
/
Microtia is a congenital deformity in which the outer ear does not fully develop during the first trimester of pregnancy. As a result, the external ear is small and misshapen.
Microtia and Aural Atresia
Microtia most often occurs alongside aural atresia, the absence of an ear canal.
Microtia and aural atresia can be unilateral (affecting one ear) or bilateral (affecting both ears). Of the thousands of microtia patients Dr. Arturo Bonilla has evaluated at his San Antonio practice, approximately 10% were bilateral.
Microtia most often occurs in one ear, in males, and on the right side. It may also be part of other medical conditions such as hemifacial microsomia, Goldenhar syndrome, and Treacher-Collins syndrome.
What Causes Microtia?
Though doctors don't know the exact cause of microtia, they often attribute it to a decreased blood supply to the developing ear in-utero. Others have theorized certain medications taken by the mother during pregnancy or environmental factors may be the cause of the deformity.
As a parent, you may have feelings of guilt if your child has microtia, but it is not your fault. You can, however, correct the condition with the help of Dr. Bonilla in San Antonio. He is a plastic surgeon who deals exclusively with pediatric ear deformities and concentrates on rebuilding the external ear.

Special Considerations For Children With Bilateral Microtia
Children born with bilateral microtia are managed differently than those with unilateral microtia. Children with unilateral microtia have one normal ear that allows them to hear. Children with bilateral microtia don’t have that luxury. Their hearing loss requires amplification with a bone-conduction hearing aid.
There are usually three specialists involved in obtaining a bone-conduction hearing aid. The primary care doctor usually refers the child to an ear, nose, and throat specialist. A hearing test is performed by an audiologist who typically dispenses and tests the hearing aid.
Understanding Bilateral Microtia
If you want to understand the kind of hearing loss a child with bilateral microtia and atresia experiences, it is simple to reproduce. Simply place a finger in each ear to block the ear canal. That is similar to their experience.
Bone conduction is the solution for this hearing loss. Because the vast majority of children with microtia have normal inner ears (where the hearing nerve is located), sound travels through the skull via vibrations. A sound will strike the skull, nose, jaw, etc., and vibrations are transmitted straight to the inner ears, totally bypassing the ear canals.
The 4 Microtia Classifications
Many normal features of the ear are present, but the ear appears smaller. An ear canal may or may not be present.
The ear is missing more of the normal features, but the earlobe is present. The helix (rim) of the ear is not fully developed at the top. An ear canal may or may not be present.
The top half of the ear is composed of disorganized cartilage while the bottom half usually has a relatively normal earlobe in a more vertical position. An ear canal is almost always missing. This is the most common form of microtia.
Also called anotia, this severe form of microtia involves the total absence of the external ear. Patients often have a low-set hairline and an ear canal is usually missing.
Any degree of microtia can involve a missing ear canal, or aural atresia, that causes hearing loss.
Your Treatment Options
The external ear does not always require medical treatment, but your options include:
- Surgery with natural cartilage
- Surgery with polyethylene implant
- Ear prosthetic
- 3D printed ear (pending FDA study)
Though unilateral atresia may not require intervention, your treatment options for hearing loss include:
- Bone-conduction hearing aid via Softband
- Bone-conduction implanted hearing aid
- Atresiaplasty or canalplasty (surgical opening of the ear canal)
Dr. Bonilla's Technique
Dr. Bonilla only performs microtia surgery using natural cartilage from the rib. This method offers several advantages over the plastic polyethylene alternative, such as:
- Less anesthesia
- Natural look, feel, and bend
- Shorter surgery times
This technique is the most accepted microtia treatment worldwide and it can even be used to reconstruct ears in anotia patients. It is a life-changing treatment that can increase your child's confidence and provide them with a sense of normalcy throughout their life.

Rib Cartilage Reconstruction Timeline
The process of rib cartilage reconstruction can give your child a new ear in as little as four months. The treatment involves a minimum of two surgeries in San Antonio and several steps:
"Our own rib cartilage has a much longer life than plastic polyethylene implants and it makes for a better final reconstruction."
Though treatment can be completed in just two surgeries, your child may require more, especially if they have bilateral microtia. Dr. Bonilla will never rush treatment and will make sure your child's best interests steer the process for the best possible results.
Natural Cartilage vs. Plastic Polyethylene Implants
Dr. Bonilla is a strong believer in using natural rib cartilage for ear reconstruction instead of a manufactured product that is composed of hard, plastic material. Our own rib cartilage has a much longer life than plastic polyethylene implants and it makes for a better final reconstruction.
A plastic polyethylene implant has the risk of exposure or fracture, while rib cartilage bends naturally, which is more realistic and makes the ear safer from trauma for the rest of the patient’s life.
Why Was the Microtia Missed During My Ultrasound?
You may be wondering why this condition was not detected during the ultrasound. Ultrasounds are used for:
- Estimating delivery date
- Detecting ectopic pregnancies
- Detecting heart rate
- Confirming the normal anatomy of vital structures such as the heart, brain, lungs, and kidneys
The ultrasound detects many important functions, but the ears are not the top priority.
