Microtia Grades Explained: What Grades 1 Through 4 Mean for Your Child’s Ear, Hearing, and Reconstruction Options, From Microtia Expert Dr. Youssef Tahiri, Associate Professor of Surgery at Cedars-Sinai

Your child’s chart says “microtia, Grade 3″ (or Grade 1, 2, or 4), and nobody has explained what that number means. Is Grade 2 mild or severe? Will your child hear? What happens next, and when? If you are asking these questions, feeling worried or confused after the diagnosis is understandable.

Congenital microtia is a condition in which a baby is born with a small, underdeveloped, or absent outer ear. Microtia grades describe how fully the outer ear formed, ranging from an ear only slightly smaller than usual (Grade 1) to anotia, where there is no outer ear at all (Grade 4). Each grade affects three things: how your child’s ear looks, how their hearing is evaluated, and which reconstruction options make sense.

Dr. Youssef H. Tahiri, MD, MSc, FRCSC, FAAP, FACS, is a pediatric plastic and craniofacial surgeon and Associate Professor of Surgery at Cedars-Sinai Medical Center. He and his team at The Los Angeles Ear and Craniofacial Center guide families through this moment and explain, in plain language, what each grade means for their child. As a father himself, Dr. Tahiri treats every patient like his own child.

This guide walks through the four grades of microtia, what each can mean for hearing, and the reconstruction paths available, and it should leave you with clearer questions to bring to your child’s specialists.

Key Takeaways

• Four grades: Microtia grades run from Grade 1 (a smaller ear with most structures present) to Grade 4 (anotia, no outer ear).
• Appearance, not hearing: The grade describes how the outer ear looks. It does not, by itself, predict how your child hears.
• Aural atresia is common: An absent or narrow ear canal (aural atresia) often comes with microtia and causes conductive hearing loss.
• Hearing first: Every grade calls for an early hearing evaluation with an audiologist and an ENT (ear, nose, and throat) specialist.
• Three reconstruction paths: MEDPOR™ Ear Reconstruction, Rib Cartilage Ear Reconstruction, and Ear Prosthesis differ in starting age, number of stages, and whether a donor site is needed.
• A plan built for your child: Dr. Tahiri and his team build an individualized plan, starting with a Free Microtia Consultation, often virtual.

What Is Microtia?

Microtia is a congenital condition in which the outer ear (the pinna) is small, underdeveloped, or absent at birth. The word itself simply means “small ear.” For some children, the difference is barely noticeable, while for others the outer ear did not form at all.

Microtia can affect one ear or both. Unilateral microtia affects one ear, while bilateral microtia affects both ears. One-sided microtia is far more common: across several population studies, 77% to 93% of affected individuals have unilateral involvement, and the right ear is affected more often than the left.

How common is it? According to the CDC, researchers estimate that 1 in every 3,800 babies has anotia/microtia in the United States.

Many children with microtia also have congenital aural atresia, meaning an absent or narrow ear canal (the external auditory canal, which carries sound toward the eardrum). When the canal is missing or blocked, sound cannot travel through it normally, resulting in conductive hearing loss on that side. 

That is why hearing care is coordinated with audiology and ENT specialists alongside outer ear reconstruction. Both how the ear works and how it looks matter to your child’s future.

To describe the condition consistently, doctors assign a grade based on how fully the outer ear formed. The sections below explain what each grade means.

How Is Microtia Classified, and What Are the Differences Between the Grades?

Microtia is classified into four grades based on how fully the external ear formed, with the differences between the grades ranging from a smaller but recognizable ear (Grade I) to complete absence of the outer ear (Grade IV, or anotia). Grade II describes a partially formed ear with missing or underdeveloped structures, while Grade III typically involves a small, peanut-shaped remnant of skin and cartilage.

More than one grading system is in use. The Marx classification, the first system published in 1926, remains one of the most widely used. Later systems by Weerda and Aguilar changed the criteria and terms. 

Because these systems differ, no single scale is universal, and one clinic’s “Grade 3” may be described slightly differently by another. Most families will meet the four-grade description below, which our practice also calls four “stages.”

Dr. Tahiri is the co-author, with Dr. John Reinisch, of the 2019 textbook Modern Microtia Reconstruction: Art, Science and Clinical Techniques, published by Springer, which covers how microtia is classified and how each presentation is reconstructed. In practice, the grade starts a conversation about options and timing, not a verdict on what your child needs.

Grade	Ear structures present (helix, lobule, tragus)	Ear canal	Typical hearing	Microtia reconstruction path
Grade I	Smaller ear with most normal landmarks, including the helix, lobule, and tragus	May be normal, narrowed, or missing	Varies by child; confirmed by audiology and ENT testing	MEDPOR™ Ear Reconstruction, Rib Cartilage Ear Reconstruction, or Ear Prosthesis, chosen for each child
Grade II	Lower ear better formed; upper ear (helix) underdeveloped; lobule usually present	Often narrow (canal stenosis) or missing	Varies by child; confirmed by audiology and ENT testing	MEDPOR™ Ear Reconstruction, Rib Cartilage Ear Reconstruction, or Ear Prosthesis, chosen for each child
Grade III	Small peanut-shaped remnant of skin and cartilage; lobule usually present	Usually absent	Conductive hearing loss on that side is common; confirmed by testing	MEDPOR™ Ear Reconstruction, Rib Cartilage Ear Reconstruction, or Ear Prosthesis, chosen for each child
Grade IV (anotia)	No external ear structures	Usually absent	Conductive hearing loss on that side is common; confirmed by testing	MEDPOR™ Ear Reconstruction, Rib Cartilage Ear Reconstruction, or Ear Prosthesis, chosen for each child

The hearing column is a general picture only. Ear canal status and hearing vary from child to child, and only audiology and ENT testing confirm them. The reconstruction column lists options, not guarantees: no grade is tied to a particular method or result.

The key distinction is simple. Grade IV (anotia) means the outer ear is completely absent, while Grades I through III describe an outer ear that is small or only partly formed, with some tissue present.

What Is a Grade 1 Microtia Ear?

A Grade 1 microtia ear (grade I microtia) is a smaller ear that keeps most of its normal landmarks. Stage I is characterized by a small ear with mostly normal external development, and Stanford Medicine Children’s Health describes it similarly: the ear is smaller than normal, but key features of a normal ear are present, sometimes with minor shape changes.

The recognizable features usually include:

• A defined helix: The curved outer rim of the ear
• An earlobe: The soft lower part of the ear, usually in a typical position
• A typical overall shape: Often including the tragus, the small flap in front of the ear canal opening

The external auditory canal (the ear canal) may be normal. It may also be narrowed (canal stenosis), and in some children it is missing. A narrowed canal can limit how well sound travels to the middle ear.

Grade 1 is the mildest in the four-grade system. The CDC notes that Type 1 is the mildest form, where the ear keeps its normal shape but is smaller than usual.

Even in mild cases, a hearing evaluation matters. A narrow canal may or may not affect hearing, and only testing with an audiologist and an ENT specialist can confirm. Dr. Tahiri and his team coordinate with these specialists to ensure your child’s appearance and hearing are understood from the start, without promising a particular hearing result.

What Does Grade 2 Microtia Look Like?

Grade 2 microtia, also called grade II microtia, is a partly formed outer ear with some recognizable structures. Our practice describes Grade II as some irregular external development, especially in the top two-thirds of the ear, and Stanford notes that much of the lower two-thirds of the ear is still present.

In practical terms, the upper part of the affected ear, including the helix (the curved outer rim), is often underdeveloped or missing. The lobule (earlobe) is usually present, and the tragus (the small flap in front of the canal opening) may also be present. The ear looks smaller and less defined than the other side.

The ear canal is often narrowed (canal stenosis) or absent (aural atresia). When the canal is severely narrowed or missing, sound cannot reach the middle ear normally, which can cause conductive hearing loss on that side.

Grading systems vary by surgeon, and features vary from child to child. For that reason, your child’s specialist confirms the grade after examining the ear. Dr. Tahiri and his team use a careful physical exam and imaging when it is needed to understand your child’s anatomy, which shapes both reconstruction planning and the hearing plan.

What Is Grade 3 Microtia?

Grade 3 microtia, or grade III microtia, is a small, underdeveloped, “peanut-shaped” outer ear, usually with no ear canal. It is also the grade families hear about most often: Stage III is the most common grade of microtia, and patients with this grade have small, underdeveloped ears with no ear canal.

Typical features of Grade III microtia include:

• A vertical ridge of skin and cartilage: This small remnant gives the ear its peanut shape.
• A lobule (ear lobe) that is usually present: It may sit slightly out of its usual position.
• No recognizable upper ear folds: No defined helix or inner fold pattern.

Grade 3 microtia usually comes with congenital aural atresia, an absent or narrow ear canal. Stanford notes that in grade III microtia, the ear canal is usually completely absent (aural atresia), causing conductive hearing loss in the affected ear. When only one side is affected, a child hears through the other ear but may find it harder to tell where sounds come from or to follow speech in a noisy room.

Dr. Tahiri and his team work with audiology and ENT specialists to assess hearing alongside ear reconstruction, and we openly discuss hearing options, including bone-conduction devices and ear canal surgery, based on your child’s anatomy. We do not promise any specific hearing result.

You can compare your child’s ear with the grade-by-grade clinical photos in our microtia reconstruction photo gallery. If you are unsure about the grade, a Free Microtia Consultation, which can start virtually, can confirm it and walk through every option.

What Is Grade 4 Microtia (Anotia)?

Grade 4 microtia, also called grade IV microtia or anotia, is the complete absence of the external ear. Stanford describes grade IV as a complete absence of the external ear with no remnants, and the CDC calls Type 4 the most severe, with all external ear structures missing.

With anotia, the ear canal is usually absent too. Our practice notes that Stage IV microtia patients have no external ear structure or ear canal.

Anotia is the rarest grade. Stanford describes it as rarely seen, and families of a child with anotia are often the ones who have found the least information to go on.

A missing ear canal usually causes conductive hearing loss on that side. Early audiology and ENT evaluation therefore comes first, often before reconstruction is discussed. Once the hearing plan is in place, all three reconstruction paths can be considered:

• MEDPOR™ Ear Reconstruction: A porous polyethylene framework, placed in a single outpatient procedure
• Rib Cartilage Ear Reconstruction: A framework carved from the child’s own rib cartilage, done in several stages at an older age
• Ear Prosthesis: A custom prosthetic ear, arranged through a referral to a specialist who makes prostheses

The right choice depends on your child’s anatomy, age, and your family’s preferences. Dr. Tahiri and his team plan care together with audiology and ENT specialists, set realistic expectations, and do not promise any appearance or hearing result.

How Does Each Microtia Grade Affect Hearing?

Each microtia grade affects hearing differently depending on how fully the ear canal and middle ear developed. Grade I may involve mild or no hearing loss, while Grades II, III, and IV are more commonly associated with conductive hearing loss, particularly when the ear canal is narrowed or absent. 

Conductive hearing loss occurs when sound cannot travel normally through the outer or middle ear, rather than because of an inner-ear problem. Microtia epidemiology reports that more than 90% of individuals with microtia experience conductive hearing loss on the affected side.

The following patterns may occur across the four microtia grades, but hearing depends on how the ear canal and middle ear have developed:

• Grade I: The ear canal may be present, narrowed, or missing. When the canal is open, the eardrum and middle ear may be near-normal, and hearing loss may be mild or absent.
• Grade II: The ear canal is often narrowed or missing, and conductive hearing loss on that side is common.
• Grade III: The ear canal is usually absent. With aural atresia, the eardrum is often missing, and the small middle ear bones are often incompletely formed, and conductive hearing loss on that side is expected.
• Grade IV (anotia): Usually no ear canal, with conductive hearing loss on that side.

Our practice explains that patients with aural atresia typically also have incomplete formation of the small middle ear bones and often lack an eardrum. Only an audiologist’s hearing tests show how each ear actually hears.

Early hearing tests start at birth. Every newborn receives a hearing screen, and babies with canal atresia or stenosis usually fail the newborn hearing screening and are referred to a pediatric audiologist for diagnostic testing. 

The Joint Committee on Infant Hearing’s 2019 position statement sets the “1-3-6” benchmark: screening completed by 1 month, audiologic diagnosis by 3 months, and enrollment in early intervention by 6 months.

When both ears have atresia (bilateral atresia), hearing loss is significant, and a hearing device is needed to support speech and language development. A patient with microtia and aural atresia in both ears will be significantly hard of hearing and require a hearing aid. Our team plans hearing care together with audiology and ENT, and we do not promise any hearing result.

How Does a Bone-Conduction Hearing Device Affect Microtia Ear Surgery?

A softband bone-conduction device sits outside the body and does not limit later microtia reconstruction. It rests against the head on an elastic band and sends sound as vibration through the skull bones to the inner ear, bypassing the missing ear canal, and nothing is implanted near the ear.

Audiologists fit these devices early because hearing matters for speech and language development. At Seattle Children’s, for example, your child will start wearing the headband in their first months of life.

Surgically implanted bone-conduction devices differ because their placement must be planned around the ear reconstruction. Seattle Children’s notes that surgery to rebuild the outer ear can affect options to treat hearing loss, and the reverse is also true: an implant site or scar in the wrong spot can leave less healthy skin and tissue near the ear. That matters because the reconstructed framework needs well-vascularized tissue to cover it, along with a skin graft.

The simplest way to avoid that conflict is to plan both at the same time. In our practice, we can easily place a modern implanted bone-conduction device (OSIA) during microtia reconstruction, using the same incision, so there are no new incisions and no second anesthetic. Hearing care is a joint plan between Dr. Tahiri and his team, your child’s audiologist, and an ENT (otology) specialist, and we do not promise any hearing results.

If your child already has a hearing plan, bring it to your Free Microtia Consultation, and we can plan the timing of any device and reconstruction together.

Does the Microtia Grade Matter Differently When One Ear or Both Ears Are Affected?

Microtia grade describes the development of each outer ear, whether one or both ears are affected. The distinction between unilateral and bilateral microtia matters for hearing care and treatment planning, because the grade alone does not tell us how well either ear hears.

Unilateral microtia (one side) is more common than bilateral microtia (both sides). With unilateral microtia and atresia, the other ear usually hears normally, so a young child’s hearing loss on the affected side may be less noticeable. Even so, one-sided hearing loss can make it harder to locate sounds and understand speech in noisy settings.

Research on children with unilateral hearing loss describes listening-related fatigue that may contribute to educational and social difficulties, especially in noisy classrooms where following speech takes extra effort. Our practice also notes that the brain has difficulty filtering out background noise when a child hears on only one side.

When microtia and atresia affect both ears, significant hearing loss requires early hearing support, typically through a fitted hearing device such as a bone-conduction device, to support speech and language development. Hearing management begins early, while ear reconstruction is planned separately according to the child’s needs.

In bilateral microtia, each ear can have a different grade, for example, Grade 2 on one side and Grade 3 on the other. Because outer-ear development can differ, each ear needs its own assessment and reconstruction plan. Dr. Tahiri and his team coordinate hearing care with audiology and ENT specialists alongside ear reconstruction, without promising any hearing result.

When Should a Child With Microtia Get a Temporal Bone CT Scan?

A child with microtia should generally get a temporal bone CT scan when imaging is needed to plan treatment, rather than during the newborn period. According to Integrated Microtia and Aural Atresia Management (2022), this imaging is not recommended for newborns and is typically reserved for surgical planning or suspected cholesteatoma.

Our practice’s CT protocol recommends scans at 2.5 years for children being evaluated for ear canal repair, based on early-intervention research, including Atresia Repair Before Microtia Reconstruction: Comparison of Early With Standard Surgical Timing (Otology & Neurotology, 2009).

Other children’s hospitals wait longer: Nemours KidsHealth notes that imaging usually isn’t done until children are closer to 6 years old. Either way, the scan is timed for a toddler or young child, not a newborn.

There are good reasons to wait:

• Lower radiation exposure: Timing CT for a clear clinical need can help avoid unnecessary or repeated scans.
• Less anesthesia or sedation: Many young children need sedation to hold still for a clear scan, and a single well-timed scan avoids repeats.
• Better accuracy: The temporal bone and the small middle ear bones need time to grow before a CT scan can assess them accurately.

Our practice waits until the child is old enough for the scan and the middle ear bones are large enough to assess clearly, so the results can guide treatment planning. This helps avoid unnecessary radiation exposure and, if sedation or anesthesia is needed, the associated risks.

The scan maps the external auditory canal, eardrum, and middle ear to plan hearing care. It helps show whether your child may be a candidate for ear canal repair (atresiaplasty) and helps rule out a cholesteatoma, a skin cyst that can grow behind trapped debris. Your audiology and ENT team decides whether and when the scan is needed. In the meantime, hearing is followed with newborn screening and follow-up testing, neither of which requires a CT scan.

Why Are Babies Born With Microtia?

Babies are born with microtia when the outer ear does not fully develop during early pregnancy, though the exact cause is usually unknown. According to the CDC, microtia and anotia develop during the first few weeks of pregnancy, often before a parent knows they are expecting.

Remember, microtia isn’t caused by anything you did or didn’t do during pregnancy. We tell every family the same thing: to date, to our knowledge, microtia isn’t caused by anything the mother did during pregnancy.

The CDC identifies known causes and possible risk factors associated with microtia:

• Changes in the baby’s genes or chromosomes: A known cause in some babies
• Certain medicines during pregnancy: Such as isotretinoin (Accutane^®)
• Maternal diabetes before pregnancy: A factor that might increase risk
• A maternal diet low in carbohydrates and folic acid: Another factor that might increase risk

Microtia is also somewhat more common in boys. A review of microtia epidemiology and genetics estimates a 20% to 40% increased risk compared to females, which reflects patterns in how the condition develops, not anything families did.

A prenatal ultrasound can sometimes show microtia, but it is often missed. Stanford notes that prenatal ultrasound often doesn’t detect it, and most diagnoses happen at birth, when the ear is visible during the newborn exam.

For questions about inheritance and related conditions, see the syndromes section below and the FAQ on whether Grade 3 microtia can be passed on.

What Syndromes Are Associated With Microtia?

The syndromes associated with microtia include Goldenhar syndrome, hemifacial microsomia, and Treacher Collins syndrome. Microtia usually occurs on its own, but less commonly, it is part of a broader craniofacial condition that can also involve the jaw, face, airway, or hearing.

The syndromes families most often hear about include:

• Goldenhar syndrome and hemifacial microsomia: Related conditions in which one side of the face develops less fully than the other, often affecting the ear, cheekbone, and jaw.
• Treacher Collins syndrome (mandibulofacial dysostosis): A genetic condition affecting the cheekbones, jaw, and ears, often including the ear canal and middle ear.

When microtia is part of a syndrome, ear reconstruction alone is not the whole answer. A syndromic diagnosis calls for a team evaluation of the jaw, airway, hearing, and face, and the plan is built around all of your child’s needs, not just the ear.

Dr. Tahiri completed a fellowship at Children’s Hospital of Philadelphia and the University of Pennsylvania, where he focused on complex craniofacial and reconstructive surgery. He coordinates reconstructive planning with ENT and craniofacial partners. Learn more on our pages about Treacher Collins syndrome, Goldenhar syndrome, and hemifacial microsomia.

What Are the Treatment Options for Different Grades of Microtia?

The treatment options for different grades of microtia depend on the grade, your child’s anatomy and age, their hearing needs, and your family’s preferences. Milder grades may need less extensive reconstructive surgery, while Grades III and IV (anotia) usually need full microtia reconstruction to build a complete outer ear.

There are three main paths:

• MEDPOR™ Ear Reconstruction: A synthetic porous polyethylene framework, often placed in a single stage and possible at a younger age.
• Rib Cartilage Ear Reconstruction: A strong autologous option that uses the child’s own rib cartilage, done in several stages at an older age, with a chest donor site.
• Ear Prosthesis: A custom prosthetic ear, fitted by an anaplastologist, for families who prefer to avoid microtia repair surgery.

Dr. Tahiri and his team perform procedures at K and B Surgical Center, an accredited shared surgical facility, and work alongside board-certified pediatric anesthesiologists and an experienced otologist with special training in aural atresia.

Which Microtia Grades Are Suited to MEDPOR™ Ear Reconstruction?

MEDPOR™ Ear Reconstruction can be considered for any grade of congenital microtia, including anotia, because suitability depends on the child’s anatomy and blood supply rather than on grade alone. Our practice lists patients with congenital microtia as candidates, along with children and adults with a traumatic ear loss or an earlier reconstruction that did not turn out well.

MEDPOR™ is a synthetic porous polyethylene (PPE) framework shaped like a natural ear. Our practice’s PPE implants include MEDPOR™ and the latest iteration, SUPOR™, and Dr. Tahiri now uses the newer SUPOR™ framework. The procedure is performed as an outpatient procedure, usually in a single stage.

Our practice offers this reconstruction starting at about age 3, and we consider ages 3.5 to 5 the ideal window, right before kindergarten. Earlier reconstruction is possible because a rib graft isn’t needed and because ears reach 85% of adult size by 3.5 years.

The child’s own tissue covers the framework. We typically harvest a superficial temporal fascia flap, a thin layer with its own blood supply beneath the scalp, and place a skin graft over it. We harvest the fascia through the same ear incision, avoiding a separate scalp incision.

Candidacy depends on your child’s anatomy, including a healthy blood supply to the fascia, and on the hearing plan. We confirm this at a Free Microtia Consultation. Like any surgery, it carries risks, including temporary swelling, infection, and, in rare cases, exposure of the implant framework, and Dr. Tahiri reviews each risk with you before you decide.

Rib Cartilage Ear Reconstruction is another valid option many families consider. The trade-offs are an older starting age, more surgeries, and a chest donor site, and the right choice depends on your child’s age, anatomy, and full care plan.

When Is Rib Cartilage Ear Reconstruction the Right Choice for a Microtia Grade?

Rib Cartilage Ear Reconstruction suits children who have grown enough rib cartilage and whose families prefer an ear built from the child’s own tissue. This technique uses only the body’s own tissue and has a long track record.

In a rib graft, the surgeon removes cartilage from several ribs through a chest incision, then carves and pieces it into an ear framework, which is placed under the skin. The rib graft leaves a chest donor site and a permanent scar.

Timing is later in childhood. Rib grafts start when the child has grown big enough, typically between six and ten years of age, to provide enough cartilage for an adult-size ear.

The reconstruction is done in stages. After the framework heals, later surgeries lift the ear away from the scalp and reposition the lobule (earlobe), often with a skin graft. The number of surgeries varies by child and surgeon.

The real strength of rib cartilage is that it is the child’s own living cartilage, which can heal like any other tissue and doesn’t require an implant. Compared with MEDPOR™ Ear Reconstruction, it involves more stages, a donor site with its own recovery and hospital stay, and an older starting age. 

Families should know that, after considering several reconstruction techniques, Dr. Tahiri decided to offer only porous polyethylene ear reconstruction, and he explains the rib graft option honestly at consultation. The decision rests on your child’s grade, anatomy, and your family’s priorities, with no promised outcome.

Is an Ear Prosthesis an Option for Any Microtia Grade?

A custom Ear Prosthesis is an option families can consider at any microtia grade, and an adhesive-retained prosthesis needs no surgery. A prosthetic ear is a custom-made external ear, fabricated from a mold of the other ear to match its shape, size, and color.

Prosthetic ears attach in one of two ways: with a skin-safe adhesive or by snapping onto small implant posts placed in the bone near the ear (an implant-anchored, or osseointegrated, prosthesis). Our practice does not make prosthetic ears itself; Dr. Tahiri can help determine candidacy and refer you to an outstanding anaplastologist, a specialist who designs and fits prosthetic ears.

A prosthesis can suit Grade IV (anotia) or cases where little ear tissue remains. It usually suits older patients and adults, since prosthetic ears are typically not a good treatment option for children, who tend to knock them off during play.

Compared with MEDPOR™ Ear Reconstruction and Rib Cartilage Ear Reconstruction, a prosthetic ear is removable, needs daily cleaning, and needs replacement over time: our practice notes these prostheses last between one and three years, depending on care and activity. A prosthesis restores appearance but does not restore hearing.

Dr. Tahiri and his team review the prosthesis option alongside reconstruction during a Free Microtia Consultation, with no promised result.

How Do I Choose the Right Surgeon for Microtia Reconstruction?

Choosing the right surgeon for microtia reconstruction is one of the most important decisions you will make for your child. Microtia is rare, and not every plastic surgeon routinely performs microtia reconstruction. This checklist can help:

1. Routine experience across all four grades: Choose a surgeon who performs microtia reconstruction routinely for every grade, including anotia. Dr. Tahiri has “treated over 25,000 patients with congenital craniofacial deformities and microtia/atresia in over 40+ countries.”
2. Honest guidance on every option: Confirm the surgeon explains MEDPOR™ Ear Reconstruction, Rib Cartilage Ear Reconstruction, and Ear Prosthesis with honest trade-offs on age, staging, and donor site, including the options they do not perform themselves.
3. Coordinated hearing care: Ask whether the surgeon works with an audiologist and an ENT (otology) specialist so they can plan hearing care alongside reconstructive surgery rather than after.
4. Training and credentials: Check training in pediatric plastic and craniofacial surgery. Dr. Youssef H. Tahiri, MD, MSc, FRCSC, FAAP, FACS, trained at McGill University, where he completed his plastic surgery residency and earned a Master’s degree in Experimental Surgery with honors, followed by a craniofacial fellowship at Children’s Hospital of Philadelphia. 

He is certified by the Royal College of Physicians and Surgeons of Canada and the American Board of Plastic Surgery, and he is an Associate Professor of Surgery at Cedars-Sinai Medical Center.

5. Published work: Dr. Tahiri co-authored Modern Microtia Reconstruction: Art, Science and Clinical Techniques (2019), which you can order through our practice.

Families outside Los Angeles can start with a free virtual microtia consultation and travel once a plan is in place.

How Can You Support a Child Living With Microtia?

Teasing, bullying, and self-esteem worries tend to come up once a child starts school and becomes more aware of looking different. Research on children with craniofacial differences, including microtia, describes peer difficulties (such as teasing and bullying) in the primary school years. With support at home and at school, children with microtia can thrive socially and academically.

Here are some ways to help:

• Talk to teachers. Tell your child’s teachers about their hearing loss and ask for classroom seating that favors the better-hearing ear, since one-sided hearing loss makes noisy classrooms harder.
• Give your child the words. Short, confident phrases, such as “My ear formed differently, and my doctors are helping me,” make it easier to answer classmates’ questions.
• Find community. Ear Community connects families and people living with microtia for peer support and shared experience.
• Let your child have a say. As your child gets older, involve them in decisions about when to start treatment. Seattle Children’s notes that most children are mature enough to take part in treatment decisions by age 7, and a child’s own readiness should guide the plan.

Families who have traveled to our practice say the same thing about feeling understood. A family from Romania wrote that Dr. Tahiri “assured us that our son was in good hands and that he would care for him as if he were his own child” (Mirela G., Google review). 

A family from Texas wrote that Dr. Tahiri “was professional, compassionate, patient, and truly took the time to make sure we understood everything” (Orlando G., Google review). And the Leda family, who traveled from Poland for their son’s reconstruction, shared that “His approach to children is exceptional” (Leda family, practice testimonial).

Microtia Grades FAQs

1. At what age can microtia be repaired?
   1. Microtia repair timing depends on the reconstruction method, your child’s growth, and the status of the ear canal, not on the grade alone. MEDPOR™ Ear Reconstruction can be done at a younger age, often in a single stage, and our practice offers it from about age 3, with reconstruction possible as early as 3 to 3.5 years according to our treatment timeline. Rib Cartilage Ear Reconstruction, a rib graft, waits until the child has enough rib cartilage, typically between 6 and 10 years of age, and requires two to five surgical stages.Ear canal repair for aural atresia is timed with audiology and ENT specialists and planned around the ear reconstruction. Hearing support through audiology, such as a softband bone-conduction device, can begin long before your child is old enough for reconstruction, with no promised hearing result. For national and international families, the first step is usually a free virtual microtia consultation.

2. Can microtia grade 3 be passed on to a child?
   1. Grade 3 microtia is rarely inherited and usually happens sporadically, with no family history. Stanford reports that in 95% of children with microtia, there is no family history, and the chance of a parent with congenital microtia passing it on is generally low.Inheritance becomes more likely when microtia is part of a syndrome. Treacher Collins syndrome, for example, is often considered an autosomal dominant condition, meaning one affected parent can pass it on, while Goldenhar syndrome usually occurs without a family history. If a syndrome is suspected, or if microtia already runs in your family, genetic counseling can explain your family’s specific risk.

3. Can a microtia grade change as a child grows?
   1. A microtia grade does not change as a child grows. Microtia is a difference in the pinna (the outer ear) that is present at birth, and the grade describes that structure.The affected ear grows with your child, but missing or underdeveloped parts, such as the helix or upper folds, do not form later. An ear that is Grade 3 at birth remains Grade 3 at age six, ten, or adulthood. Waiting will not change the grade, and Dr. Tahiri and his team base the treatment plan on it, along with your child’s anatomy and your family’s goals.

4. Are children with canal stenosis more prone to ear infections?
   1. A narrow ear canal (canal stenosis) can raise the risk of ear infections. Nemours KidsHealth notes that children with more severe stenosis may have frequent ear canal infections (otitis externa).A narrow canal can also trap earwax and skin debris behind the narrowing. The main concern is cholesteatoma, a skin cyst that can grow behind trapped debris and damage the middle ear. A study in The Laryngoscope found that a bony ear canal opening of 2 mm or less puts a child at risk of cholesteatoma. Routine checkups with an ENT (ear, nose, and throat) doctor allow the canal to be examined and cleaned when needed, and Dr. Tahiri and his team coordinate this monitoring with your child’s audiology and ENT specialists.

5.  Is microtia repair cosmetic?
   1. Microtia repair is reconstructive surgery for a congenital condition, not an elective cosmetic procedure. As Dr. Tahiri explains in our Frequently Asked Questions, a cosmetic procedure improves something that is normal, while microtia reconstruction builds an outer ear that did not fully form.The reconstructed ear has practical benefits: it makes wearing glasses easier and can help keep sunglasses and face masks in place. It can also help a child feel more confident around peers, although every child’s experience differs. Outer ear reconstruction does not restore hearing on its own. Audiology and ENT specialists plan hearing care separately.

Where Can You Get Expert Guidance on Your Child’s Microtia Grade?

Dr. Tahiri and his team offer a Free Microtia Consultation for families of a child with microtia. The consultation is free for microtia only; other conditions require a small consultation fee.

You can start with a virtual consultation from anywhere in the world, or come in person to our Beverly Hills office. During the consultation, our team reviews your child’s specific grade, their hearing test results and needs, and every microtia reconstruction option, with honest expectations and no promised outcome.

Dr. Tahiri has “treated over 25,000 patients with congenital craniofacial deformities and microtia/atresia in over 40+ countries,” and in 2019 he co-authored Modern Microtia Reconstruction: Art, Science and Clinical Techniques.

Our office is at 9033 Wilshire Blvd, Suite 200, Beverly Hills, CA 90211, and you can reach us at (310) 255-4476, Monday to Friday, 8 am to 5 pm Pacific. When you are ready, start with a virtual consultation.
