Microtia means a baby is born with a small or missing outer ear (pinna). It can affect one ear or both. Sometimes the ear canal is narrow or absent (aural atresia), which can cause hearing loss on the affected side. The condition ranges from mild shape changes to complete absence of the external ear (anotia). Children with one-sided hearing loss can still have speech-language or learning challenges if not supported early, so hearing testing and early help matter a lot. PMC+3PMC+3CDC+3

Microtia means the outer ear (the pinna) is smaller than normal, not fully formed, or missing. The ear shape may be unusual. Sometimes the ear canal is narrow or closed. Sometimes the canal is normal. Microtia can affect one ear or both ears. Some people with microtia have normal hearing. Many have some degree of hearing loss, most often a conductive type because sound cannot travel well through the canal and middle ear. The most severe form, when the ear is completely absent, is called anotia. Microtia belongs to the “anotia–microtia spectrum.” It starts during early fetal development of the first and second branchial arches. NCBI+2Children’s Hospital of Philadelphia+2


Other names

Some other names and phrases you may see:

  • Congenital auricular dysplasia (a medical way to say the outer ear did not form normally at birth).

  • External ear hypoplasia (the ear is smaller or under-developed).

  • Anotia–microtia spectrum (from a small ear to no ear).

  • Conchal-type microtia / lobular-type microtia (descriptions of which parts formed).
    These terms all refer to related appearances of the outer ear at birth. Clinicians also use formal grading systems described below. NCBI+1


Types

Doctors use grading systems to describe how much of the ear is present:

  • Grade I (mild): The ear looks like a normal ear but smaller. Most structures can be seen. The canal may be narrow.

  • Grade II (moderate): Some ear parts are missing. A small conchal bowl or lobule may be present. Canal stenosis is common.

  • Grade III (severe): Only a small “peanut-shaped” remnant remains. The canal is usually absent (atresia).

  • Grade IV: Anotia—the outer ear is absent.

These descriptions come from the classic Marx/Weerda classifications that are still widely used in ENT and plastic surgery. NCBI+2Radiopaedia+2

Doctors also note whether microtia is unilateral (one ear) or bilateral (both ears), and whether there is aural atresia (closed canal) or stenosis (narrow canal). This helps predict hearing and plan care. NCBI


Causes and risk factors

Microtia usually has more than one cause. In many families the exact cause is unknown. Below are well-described genetic, syndromic, and environmental contributors. (Important: a “risk factor” does not always mean “the cause” for a specific child.)

  1. Natural developmental variation of the first/second branchial arches
    The ear forms from small hillocks in early pregnancy. If this process is disturbed, the outer ear can be small or misshapen. This basic mechanism explains most isolated microtia. PMC

  2. Oculo-auriculo-vertebral spectrum (OAVS / Goldenhar)
    A craniofacial condition that often includes microtia, facial asymmetry, and sometimes eye or spine findings. It reflects early arch development differences. NCBI+1

  3. Treacher Collins syndrome (TCOF1 and related genes)
    This genetic condition affects cheekbones, jaw, eyelids—and the outer ear and ear canal. Conductive hearing loss is common. NCBI

  4. Branchio-oto-renal (BOR) spectrum
    A genetic condition with ear malformations (outer, middle, inner), preauricular pits/tags, and kidney anomalies; hearing loss may be conductive, sensorineural, or mixed. NCBI

  5. HOXA2 gene variants
    Rare pathogenic variants in HOXA2 can cause nonsyndromic microtia or anotia, sometimes with hearing loss and palate changes. PMC+1

  6. Other genes linked in recent studies
    Systematic reviews also implicate SIX2, HSPA9, GSC, FANCB, MARS1, CDT1 and others in some cases of microtia. Research is ongoing. BioMed Central

  7. Maternal pre-existing diabetes (type 1 or type 2)
    Case-control data show a significantly higher odds of anotia/microtia among pregnancies with pre-existing diabetes. Good pre-pregnancy diabetes control reduces many birth-defect risks. PubMed+1

  8. Gestational diabetes
    Some studies show a modest association with microtia, although results are less strong than for pre-existing diabetes. PubMed

  9. Isotretinoin (retinoic acid) exposure in early pregnancy
    A known teratogen. External ear malformations (anotia/microtia) are part of isotretinoin embryopathy. Strict pregnancy prevention programs exist for this reason. PubMed+1

  10. Thalidomide exposure (historical, rare today)
    Thalidomide can cause severe ear malformations; this is well documented in animal and human data. PubMed+1

  11. Mycophenolate mofetil (MMF) exposure
    Reports and reviews link MMF embryopathy with moderate-to-severe microtia/anotia and canal atresia when exposure occurs early in gestation. Johns Hopkins University+1

  12. Vascular disruption hypotheses
    Some researchers propose transient blood-supply changes to the branchial arch region during critical weeks may contribute to microtia in certain cases. Evidence is mixed. CDC Stacks

  13. Alcohol exposure (as part of OAVS risk mix)
    Reviews of OAVS mention prenatal alcohol exposure among environmental factors possibly increasing risk in susceptible embryos. MDPI

  14. Maternal acute illness or fever around organogenesis
    Some case-control data list maternal acute illness among factors seen more often in microtia cases, though causation is uncertain. PMC

  15. Higher maternal parity or older maternal age (associations)
    Epidemiologic work has found associations with higher parity; not all studies agree. PMC

  16. Genetic background and ethnicity
    Prevalence varies by population, suggesting genetic susceptibility plays a role. MDPI

  17. Family history
    Some families show recurrence of microtia as a multifactorial trait with variable expression. Genetic counseling can help discuss risks. MDPI

  18. Chromosomal copy-number variants (rare)
    A minority of patients have CNVs affecting craniofacial genes; testing may identify them. PMC

  19. Syndromic patterns with renal, cardiac, or limb differences
    Because microtia can appear in >50 syndromes, a careful head-to-toe exam is important. MDPI

  20. Unknown / multifactorial
    For many children, no single cause is found. Care focuses on hearing, speech, and reconstruction as needed. PMC


Common symptoms

  1. Small or missing outer ear
    The pinna looks small, folded, or absent. Appearance varies by grade. NCBI

  2. Narrow or closed ear canal
    Some children have canal stenosis or atresia, especially with higher grades. Stanford Medicine

  3. Conductive hearing loss (one or both ears)
    Sound cannot reach the inner ear well when the canal or ossicles are abnormal. NCBI

  4. Normal hearing in some cases
    Not everyone with microtia has hearing loss; type and severity vary. Children’s Hospital of Philadelphia

  5. Difficulty localizing where sounds come from
    This is common with one-sided hearing loss. It can affect safety outdoors and in traffic. NCBI

  6. Hearing problems in noisy rooms
    Background noise makes listening and learning harder when one ear is impaired. NCBI

  7. Speech-language delay (some children)
    Untreated significant hearing loss can delay speech and language; early testing helps. NursingCenter

  8. Ear infections or wax trapping (with very narrow canals)
    Stenotic canals can trap skin and wax; rare children develop canal cholesteatoma. ResearchGate

  9. Tinnitus (ringing)
    Some individuals report sound sensations in the affected ear. (Varies by inner ear status.)

  10. Balance symptoms (some)
    A minority with associated inner ear issues may have balance delays or dizziness. Frontiers+1

  11. Facial asymmetry
    Jaw and cheekbone differences may appear, especially with OAVS. NCBI

  12. Preauricular pits or tags
    Small skin pits or tags near the ear may be present. These can signal certain syndromes. NCBI

  13. Psychosocial stress
    Appearance differences and hearing challenges may affect self-esteem at school age. Support helps. PMC

  14. Learning fatigue
    Children work harder to listen and may tire faster in class (hearing-effort effect).

  15. Family worry and care coordination needs
    Parents often need clear plans for hearing, speech, and reconstructive timing. PMC

Diagnostic tests

A) Physical examination

  1. Detailed head and ear inspection with grading
    The doctor looks at size, shape, and position of the ear and assigns a grade (I–IV). This shared language guides hearing and surgical planning. NCBI+1

  2. Otoscopy (if a canal is present)
    A lighted scope checks the canal and eardrum for narrowing, wax, or skin problems. If there is no canal, this step is skipped. NCBI

  3. Full craniofacial exam
    The clinician checks jaw, cheekbones, eyes, palate, and spine to look for features of OAVS, Treacher Collins, and other syndromes that often accompany microtia. NCBI+1

  4. Screen for branchial and kidney “clues”
    Preauricular pits/tags or neck sinuses raise suspicion for BOR; these findings prompt kidney evaluation and genetics referral. NCBI

B) Simple bedside “manual” hearing tests 

  1. Rinne test (tuning fork)
    Compares air- vs bone-conducted sound at the ear. A conductive loss flips the usual result (“Rinne negative”). Useful in older children and adults. EJAO

  2. Weber test (tuning fork)
    Places the fork on the forehead. Sound localizes to the ear with conductive loss or away from the ear with sensorineural loss. NCBI

  3. Whispered-voice or finger-rub tests
    Very simple screens in cooperative patients. They do not replace formal audiology. Carepatron

  4. Behavioral audiometry (BOA/VRA/CPA)
    Age-appropriate behavioral tests (watching for responses to sounds; visual reinforcement for infants; play audiometry for toddlers) help estimate hearing when formal earphone testing is not yet possible. NursingCenter

C) Lab / pathological / genetics 

  1. Chromosomal microarray (CMA)
    Looks for small missing or extra DNA segments (copy-number variants) linked to craniofacial conditions. Consider when microtia is part of a broader pattern. PMC

  2. Targeted gene panel or exome
    Testing can include TCOF1 (Treacher Collins), EYA1/SIX1/SIX5 (BOR), HOXA2, and others when the history and exam suggest a syndrome or inherited cause. NCBI+2NCBI+2

  3. Renal workup when indicated
    Urinalysis and serum creatinine are checked if BOR is suspected or if a renal ultrasound shows concerns. Not needed for isolated microtia without clinical “red flags.” PubMed

  4. Infection/teratogen labs (only when history suggests)
    If there is a clear history or ultrasound clue, clinicians may order specific tests (for example, TORCH) to rule out infections or document exposures; this is uncommon and targeted. (General principle from perinatal evaluation guidance.) NursingCenter

D) Electrodiagnostic & physiologic audiology 

  1. Auditory brainstem response (ABR/BAER)
    Surface electrodes record the brain’s response to clicks or tones. It works even in sleeping infants and can be done by bone conduction when the ear canal is closed. It is a key test to define hearing level early. NursingCenter

  2. Automated ABR (AABR) for newborn screening
    AABR is used in many newborn programs. Babies who screen “refer” need full diagnostic ABR. NursingCenter

  3. Otoacoustic emissions (OAE)
    A tiny probe measures inner ear hair-cell echoes. If the canal is absent, OAE cannot be obtained in that ear, but it remains useful for the opposite ear. NursingCenter

  4. Tympanometry / acoustic immittance
    Checks eardrum movement and middle-ear pressure. For infants under ~6 months, a 1000-Hz probe tone is recommended to avoid false results. NursingCenter

E) Imaging & planning tools 

  1. High-resolution temporal bone CT (timed for surgery planning)
    CT shows the canal, middle ear bones, facial nerve, and windows. It is used to calculate the Jahrsdoerfer score to predict success of canal surgery. To reduce radiation in young children, many centers delay CT until about age 5–6 when atresia surgery is being considered. PubMed+2NCBI+2

  2. MRI of internal auditory canals and brainstem (selective)
    MRI shows the cochlear nerve and inner ear. It is useful if sensorineural loss is suspected, if ABR results are unusual, or when syndromes suggest inner-ear or nerve differences. infanthearing.org

  3. Prenatal ultrasound (sometimes)
    Detailed ultrasound—and occasionally fetal MRI—can detect microtia before birth, especially with 3-D techniques, but mild cases are often missed and diagnosis must be confirmed after birth. PMC+1

  4. 3-D surface photography / photogrammetry for reconstruction
    Non-radiation 3-D scans help surgeons plan ear reconstruction and create patient-specific templates or 3-D printed models. PMC+1

Non-pharmacological treatments (therapies & other supports)

There are no medicines that regrow an external ear. Care focuses on (1) checking hearing early, (2) giving a hearing solution if needed, and (3) choosing an ear reconstruction option at the right age if desired. Hearing devices can be used in infancy, and surgical or prosthetic ear reconstruction is typically considered later in childhood by a specialist team. CDC+2FDA Access Data+2

Medicines

There is no FDA-approved medicine that treats or reverses microtia or creates a new external ear. Medicines are used only for associated needs (e.g., ear infections, pain after surgery, anesthesia care, nausea control) and always under clinician supervision. Below are common supportive medicines with FDA label sources so you can review safety information; doses are individualized by weight/age/condition—follow your clinician and the product label. PMC+1

  1. Acetaminophen (paracetamol) – pain/fever after procedures
    Class: Analgesic/antipyretic. Purpose: Relieves pain/fever post-op or with intercurrent illness. Mechanism: Central COX inhibition to reduce pain signals and fever set-point. Timing: Given as directed by weight and schedule by clinician. Side effects: Generally well tolerated; overdose risks liver injury. FDA label: consult approved labeling for dosing and warnings. PMC

  2. Ibuprofen – anti-inflammatory pain control (when appropriate)
    Class: NSAID. Purpose: Reduces post-op pain and inflammation per surgeon’s plan. Mechanism: Inhibits COX-1/COX-2 to lower prostaglandins. Timing: Weight-based pediatric dosing; avoid when contraindicated. Side effects: Stomach upset, rare kidney effects; avoid with bleeding risks per label. (Use clinician guidance and FDA labeling.) PMC

  3. Amoxicillin (or guideline-based antibiotic) for acute otitis media
    Class: Beta-lactam antibiotic. Purpose: Treats bacterial middle-ear infection if the child’s hearing ear develops AOM. Mechanism: Inhibits bacterial cell wall synthesis. Timing: Course and dose per pediatric guidelines. Side effects: Allergy, diarrhea. (Use only when clinically indicated; see FDA label.) PMC

  4. Cefazolin (peri-operative prophylaxis when indicated)
    Class: First-generation cephalosporin. Purpose: Surgical infection prophylaxis per hospital protocol. Mechanism: Cell wall inhibition. Timing: Given IV before incision, sometimes after per protocol. Side effects: Allergy, GI upset. (Use hospital protocol/FDA label; not disease-specific.) PMC

  5. Ondansetron (nausea prevention around surgery)
    Class: 5-HT3 antagonist antiemetic. Purpose: Reduces post-op nausea/vomiting to protect wounds and comfort. Mechanism: Blocks serotonin receptors in the chemoreceptor trigger zone. Timing: Per anesthesiology plan. Side effects: Headache, constipation; rare QT effects. (See FDA label.) PMC

  6. Topical skin care agents (e.g., petrolatum) for incision care
    Class: Emollients/occlusives. Purpose: Keep incisions moist and protected as directed. Mechanism: Occlusive barrier supports epithelialization. Side effects: Minimal; stop if irritation. (Use surgeon instructions; check product labeling.) PMC

  7. Local anesthetics (e.g., lidocaine) used by clinicians
    Class: Sodium channel blocker. Purpose: Numbs surgical area/procedural pain. Mechanism: Blocks nerve conduction. Side effects: Rare systemic toxicity if overdosed; clinicians dose carefully. PMC

Important: Your request asked for “drugs from accessdata.fda.gov for this disease.” FDA labels confirm drug safety/indications, but no drug treats microtia itself. Medicines above are supportive and must be individualized by a clinician. For device-based hearing solutions (BAHA), the FDA clears specific devices via 510(k); see examples in the citations. FDA Access Data+2FDA Access Data+2


Dietary molecular supplement

There is no supplement proven to correct microtia or restore the outer ear. For the child, a balanced diet per pediatric guidance supports overall growth and healing around surgeries. For future pregnancies (prevention), adequate folate is important, and avoidance of certain teratogenic medicines is critical (see “Prevention”). Because supplements can interact with medicines or anesthesia, always ask your clinician before starting any product. (Authoritative sources above emphasize devices/surgery and early hearing care rather than supplements.) CDC

Examples of supportive, general-health supplements sometimes discussed by clinicians (only if deficiency or clear indication is present): vitamin D, calcium (bone health), iron (if iron-deficiency anemia), omega-3 (general nutrition), zinc (wound healing if deficient). Use clinician-guided, indication-based supplementation; do not give high-dose products to children without medical advice. (Because robust evidence for microtia-specific benefit is lacking, I have not cited these as disease-modifying.)


Immunity booster / regenerative / stem-cell drugs

There are no approved stem-cell or “regenerative” drugs to treat microtia or to regrow an external ear. The U.S. FDA specifically warns consumers that most marketed stem-cell/exosome products are unapproved and have caused serious harms (infections, blindness, tumor formation). Please avoid clinics that advertise stem-cell cures for ear growth outside clinical trials. U.S. Food and Drug Administration+2U.S. Food and Drug Administration+2


Surgeries

  1. Autologous rib-cartilage ear reconstruction (Brent/Nagata)
    Procedure: Harvest rib cartilage to sculpt a custom ear framework; place under skin and refine in 2–4 stages, often around age ~10 when enough cartilage is available.
    Why: Durable, living tissue ear with natural contours and long-term stability. Children’s Hospital of Philadelphia+1

  2. Alloplastic ear reconstruction (porous polyethylene/Medpor)
    Procedure: Implant a pre-formed porous ear scaffold covered with vascularized tissue/skin.
    Why: Option when avoiding rib harvest or seeking different timing; reconstructs ear shape. PMC

  3. Atresiaplasty/canalplasty
    Procedure: Create or widen the ear canal; may adjust ossicles.
    Why: Improve hearing and allow conventional hearing aids in selected candidates. PMC+1

  4. Bone-anchored hearing system (BAHS) implantation
    Procedure: Surgically place a small titanium fixture in skull bone for a sound processor.
    Why: Bypass the blocked outer/middle ear and deliver sound to the inner ear for reliable hearing access. (FDA-cleared devices available.) FDA Access Data+1

  5. Osseointegrated auricular prosthesis
    Procedure: Insert titanium posts in bone; attach a custom silicone ear prosthesis.
    Why: Realistic cosmetic solution when surgical ear building isn’t preferred or feasible. PMC


Practical prevention tips

Microtia has complex causes (genetic and environmental). While not all cases are preventable, these steps can lower risk from known teratogens and promote healthy development:

  1. Avoid isotretinoin (Accutane) in pregnancy—strongly teratogenic with ear anomalies reported. FDA Access Data+1

  2. Avoid mycophenolate (CellCept/Myfortic) in pregnancy—linked to external ear and facial malformations; use alternatives if possible. FDA Access Data+1

  3. Avoid thalidomide—causes severe birth defects even with a single dose. FDA Access Data+1

  4. Plan pregnancy medication review with a clinician before conception. (Essential medicines may have safer substitutes.) FDA Access Data

  5. Use folic acid per prenatal guidance and a balanced prenatal diet (general neural/craniocervical development support).

  6. Control pre-existing conditions (e.g., diabetes) before and during pregnancy.

  7. Avoid alcohol/tobacco during pregnancy.

  8. Update vaccinations (e.g., rubella) before conception as recommended.

  9. Avoid unregulated supplements/high-dose vitamin A/retinoids in pregnancy. FDA Access Data

  10. Seek early prenatal care for medication, nutrition, and risk counseling.

(Items are broad prenatal best practices; specific microtia-preventive evidence varies, but they reduce overall teratogenic risk and promote fetal health.)


When to see a doctor

  • Immediately after birth: Ensure newborn hearing screening is completed; if your baby misses the screen or “refers,” get diagnostic testing as soon as possible. Early intervention by 6 months boosts language outcomes. HealthyChildren.org

  • Any time you notice hearing or speech concerns: Ask for an audiology referral; unilateral loss also matters. PubMed

  • Before choosing surgery/devices: Meet a microtia/atresia team (ENT, audiology, plastic surgery, SLP) to plan timing and steps. PMC

  • If anyone offers stem-cell “cures”: Avoid and seek a second opinion; FDA warns against unapproved regenerative products. U.S. Food and Drug Administration


What to eat & what to avoid

  • Eat: A varied, nutrient-dense diet for children (fruits, vegetables, whole grains, proteins, healthy fats) to support growth and healing around any procedures; follow pediatric nutrition advice.

  • Avoid: Starting any supplement in a child without clinician input; high-dose vitamin A/retinoids in pregnancy; alcohol and tobacco in pregnancy. For peri-operative periods, follow the surgical team’s fasting and medication instructions. (No food can regrow an ear; nutrition supports overall health.) CDC


Frequently asked questions

  1. Can microtia be cured with medicine?
    No. Medicines do not regrow the outer ear; care focuses on hearing access and reconstruction options. CDC

  2. Does one-sided hearing loss matter?
    Yes. Even mild unilateral loss can affect language and school performance without supports. PubMed+1

  3. What hearing options exist for a baby?
    A softband bone-conduction device can provide sound early; later, a BAHS implant may be considered. FDA Access Data+1

  4. When is ear reconstruction done?
    Often around ~10 years for rib-cartilage techniques (enough cartilage available), or earlier with certain alloplastic methods at some centers. Children’s Hospital of Philadelphia

  5. Is atresiaplasty right for everyone?
    No. Suitability depends on anatomy and risks; benefits vary. A specialist team evaluates candidacy. PMC

  6. Are BAHA devices FDA-approved?
    Yes—several BAHS systems are FDA-cleared; your team will match candidacy and model. FDA Access Data+1

  7. Will my child need speech therapy?
    Often helpful, especially with unilateral loss, to optimize communication and school success. alabamapublichealth.gov

  8. Are stem-cell treatments available to regrow the ear?
    No approved stem-cell therapies for this; FDA warns about unapproved products and harms. U.S. Food and Drug Administration+1

  9. Can I prevent microtia in a future pregnancy?
    Avoid known teratogens (e.g., isotretinoin, mycophenolate, thalidomide), plan meds with your clinician, and use standard prenatal care. FDA Access Data+2FDA Access Data+2

  10. Will my child’s brain hearing (cochlea) be normal?
    Often yes; the problem is the outer/middle ear pathway. That’s why bone-conduction solutions can work well. FDA Access Data

  11. How important are school accommodations?
    Very—remote microphones and classroom strategies can improve learning. PubMed

  12. Can a prosthetic ear look realistic?
    Yes. Silicone prostheses attached to small posts can look very natural when made by experienced teams. PMC

  13. Is there a “best” surgery?
    It depends on your child’s anatomy, age, and family goals; discuss rib-cartilage, alloplastic, prosthetic, and timing options with the team. PMC

  14. What are the risks of surgery?
    Like all surgeries: infection, bleeding, scarring, implant issues; your surgeon will explain risks/benefits for each method. PMC

  15. What happens if we wait?
    You can still support language with early hearing access and therapy; cosmetic decisions can be made later with your team. alabamapublichealth.gov
