Anotia means a baby is born without the outer ear (the visible ear on the side of the head). It is the most severe end of the “microtia–anotia” spectrum: microtia means a small or under-formed ear, while anotia means no external ear at all. The ear canal may also be missing (called aural atresia), which often causes conductive hearing loss because sound cannot reach the eardrum and middle ear in the usual way. CDC+1
Anotia means the baby is born without an external ear (pinna). It sits on the severe end of the “microtia–anotia” spectrum, where microtia ranges from a slightly small or misshapen ear to almost no ear, and anotia is complete absence. Hearing can still be partly present through the inner ear, but many children have conductive hearing loss because the ear canal and middle ear are often affected. Care usually focuses on hearing rehabilitation, speech–language support, and (when appropriate) ear reconstruction. NCBI+1
Microtia–anotia together occur in about 2 per 10,000 births, and anotia alone around 0.36 per 10,000 births (rates vary by region, population, and how cases are counted). Boys and certain populations have somewhat higher reported rates. CDC Stacks+1
In early pregnancy, the outer ear (pinna) grows from six tiny swellings called the “auricular hillocks” that sit on the first and second pharyngeal arches. These hillocks fuse and migrate to the side of the head to make the full ear. If this process is interrupted—by a gene change, a blood-supply issue, or an environmental exposure—the pinna may be small (microtia) or entirely absent (anotia). NCBI+2NCBI+2
Other names
People may also call this condition “congenital absence of the pinna,” “type IV microtia,” “microtia–anotia complex,” or “external ear agenesis.” When the ear canal is also closed or absent, clinicians often use the companion term “congenital aural atresia.” NCBI+1
Types
Isolated anotia. Only the external ear is missing on one or both sides, with no recognized syndrome.
Anotia with aural atresia. The ear canal is also absent or closed; hearing is affected on that side.
Anotia within a craniofacial syndrome. The most common association is oculo-auriculo-vertebral spectrum (OAVS/Goldenhar spectrum), which can include facial asymmetry, eye findings, and spine differences. Less commonly, anotia can appear in other genetic conditions. NCBI+2NORD+2

Diagnostic Tests
Physical examination (bedside/clinical)
Newborn head and ear exam. The clinician confirms absence of the pinna and looks for canal opening, skin tags, or other external landmarks; both sides are examined. CDC
Craniofacial assessment. Checks jaw size, facial symmetry, eye structures, and palate to look for patterns like OAVS/Goldenhar that travel with ear malformations. NCBI
Spine and chest exam. Looks for vertebral anomalies or rib differences that can co-occur in first/second arch syndromes. NCBI
Cardiac exam. A careful heart exam (and follow-up testing) because cardiac differences are more common than in the general population among children with microtia/anotia. PubMed+1
Kidney/abdomen screening in clinic. Palpation and history to prompt renal ultrasound, given higher rates of renal anomalies reported in these children. PubMed
Manual/bedside hearing tests (age-appropriate)
Newborn hearing screen. Most babies get automated screening using Otoacoustic Emissions (OAE) or Automated Auditory Brainstem Response (A-ABR) before going home; babies with anotia need prompt diagnostic follow-up. EHDI PALS
Tympanometry and acoustic reflex testing (when a canal is present) to assess middle-ear function and reflex pathways; not feasible if the canal is absent. Heuser Hearing Institute
Tuning-fork (Rinne/Weber) tests in older children/adults to screen conductive versus sensorineural patterns when feasible.
Age-appropriate behavioral audiometry (visual reinforcement or play audiometry) to map hearing thresholds as the child grows.
Lab and pathological / genetic tests
Genetics consultation. A clinical geneticist reviews features and family history to judge if anotia is isolated or syndromic.
Chromosomal microarray (CMA). Looks for copy-number variants (small deletions/duplications) linked to craniofacial syndromes; helpful when features suggest a broader condition. www.elsevier.com

Syndrome-directed labs (as indicated). For example, additional tests if a specific syndrome is suspected based on exam.
Electrodiagnostic hearing tests
Diagnostic ABR (Auditory Brainstem Response). Measures how the hearing nerve/brainstem respond to sound; works even when the child is asleep and does not require an ear canal on the test side (bone-conduction ABR can be used). Children’s Hospital of Philadelphia
OAE (Otoacoustic Emissions). Screens cochlear (outer hair cell) function when access is possible; together with ABR helps decide on early hearing support. EHDI PALS
Imaging tests
High-resolution CT (temporal bone) at the right age. Detailed CT is usually deferred until later childhood (often around 5–6+ years) when surgical planning is considered, to reduce radiation and capture more mature anatomy of the middle/outer ear and skull base. PMC+1
MRI of the temporal bones/internal auditory canals (select cases). Helps assess inner ear and nerve when CT or ABR raise questions about sensorineural components or anatomy.
Renal ultrasound. Because renal anomalies are reported more often in children with microtia/anotia than in the general population, many teams screen with kidney ultrasound, especially if other features suggest a syndrome. PubMed+1
Echocardiogram and spine imaging (as indicated). Cardiac ultrasound and, when needed, spine films/MRI are considered if exam suggests heart or vertebral involvement; several studies and reviews support heightened vigilance for these associated anomalies. PubMed+1
Non-pharmacological treatments (therapies & other supports)
Evidence-based note: These are the core, real-world interventions that improve hearing access, language, learning, and quality of life. None of them “cure” anotia; they optimize outcomes.
Newborn hearing screening and full audiology work-up
Every baby should get newborn screening; if anotia is present, arrange diagnostic ABR, bone-conduction thresholds, and middle/inner ear assessment. This maps the type and degree of hearing loss early so you can act before speech delays emerge. NCBIEarly amplification with soft-band bone-conduction devices
Before age 5 (when implants are usually not placed), a soft-band BAHA/Osia trial gives immediate sound access via bone conduction. Early, consistent use supports speech and brain development. PubMed+1Bone-anchored hearing implant (when age/criteria met)
Around ~5 years (varies by system/regulations), surgery can place a percutaneous or transcutaneous bone-anchored device to provide stable, day-long hearing access with strong speech outcomes compared with unaided hearing. PubMedSpeech-language therapy / auditory-verbal therapy
Therapists coach listening, speech clarity, vocabulary, and classroom strategies. Early, frequent sessions close language gaps and reinforce use of hearing tech at home and school. (Audiology and SLP guidelines uniformly recommend this.) NCBIEducational accommodations (IEP/504 plans)
Preferential seating, FM/remote-microphone systems, captioning, and quiet classrooms reduce listening effort and improve comprehension, especially in noise. These adjustments are an evidence-based part of pediatric hearing care. NCBIFamily counseling and psychosocial support
Anotia is visible; children may face questions or teasing. Psychosocial support builds resilience, self-advocacy, and positive identity while the family navigates devices and (later) reconstruction choices. NCBIOtolaryngology (ENT) care and surveillance
ENTs coordinate hearing access, evaluate ear canal/middle ear anatomy, manage infections, and time any surgeries (atresiaplasty, implant, or reconstruction) with growth and school schedules. NCBICraniofacial/genetics evaluation (when indicated)
Anotia can occur with craniofacial microsomia/Goldenhar spectrum or as part of a syndrome. A genetics/craniofacial team checks for associated features (spine, heart, kidneys) to ensure nothing is missed. PMCAtresia clinic assessment

High-quality prosthetic ears (anaplastology) can be retained with adhesives or osseointegrated abutments, offering realistic appearance without large surgery. (Options discussed in craniofacial clinics.) ScienceDirectLong-term follow-up through adolescence
As self-image, activities, and academic demands evolve, plans for hearing tech, reconstruction revisions, and counseling are updated together with the teen. NCBI
Drug treatments (what medicines are—and are not—used)
Honest evidence note: There are no medications that correct anotia or “grow” a new pinna. Medicines are used around surgeries, for device-related skin care, and to treat associated problems (e.g., ear infections after canal surgery). Below are common, legitimate medication roles. Dosages below are typical pediatric examples; exact dosing must be individualized by your clinician.
Acetaminophen (paracetamol) – pain/fever control after procedures or during device acclimatization; class: analgesic/antipyretic; common pediatric dose ~10–15 mg/kg per dose every 4–6 h (max per local guideline). Helps comfort without affecting platelets; mechanism: central COX modulation. Side effects are uncommon at correct doses (risk: liver toxicity if overdosed). NCBI
Ibuprofen – postoperative pain/anti-inflammatory; class: NSAID; typical pediatric dose ~5–10 mg/kg every 6–8 h with food; mechanism: COX inhibition; side effects: stomach upset, rare bleeding risk—surgeons may pause around major reconstruction. NCBI
Topical antibiotic drops (e.g., ofloxacin) – for canal/skin infections after atresiaplasty or with skin irritation; mechanism: fluoroquinolone bactericidal; used as directed; side effects: local irritation. NCBI
Peri-operative IV antibiotics (e.g., cefazolin) – given around framework implantation to reduce surgical-site infection risk; dose/timing per weight and protocol; mechanism: cell-wall inhibition; side effects: allergy, diarrhea. ScienceDirect
Topical corticosteroids (e.g., hydrocortisone) – for localized device pressure dermatitis; thin layer, short courses; mechanism: anti-inflammatory via glucocorticoid receptors; side effects: skin thinning if prolonged. Cochlear ProNews
Antiemetics (e.g., ondansetron) – to manage post-anesthesia nausea/vomiting; mechanism: 5-HT3 antagonism; side effects: constipation, headache. NCBI
Anesthesia medicines – used by the surgical team during reconstructions; choice/dose individualized; purpose: safe pain control/amnesia; side effects: vary; monitored continuously in the OR/PACU. ScienceDirect
Antibiotic prophylaxis/therapy for osseointegrated abutments – short courses if peri-abutment cellulitis develops; drug choice guided by local flora. PubMed
Analgesic nerve blocks (local anesthetics) – used intra-op to reduce postoperative pain; mechanism: sodium-channel blockade; side effects: rare systemic toxicity if misdosed (handled by anesthesiologists). ScienceDirect
Antibiotic ointments for skin sutures/incisions – to reduce superficial contamination in immediate postop period; thin application; side effects: contact dermatitis in rare cases. ScienceDirect
Short antibiotic courses for otitis externa – if canal reconstruction leads to debris/infection, topical therapy is standard; agents and duration per ENT. NCBI
Analgesic rotation (acetaminophen + ibuprofen as directed) – alternating medicine strategy for better comfort without excessive dosing of either drug, per pediatric protocols. NCBI
Sedation medicines for imaging (case-by-case) – some children need sedation for safe CT; tightly controlled by radiology/anesthesia teams. NCBI
Topical barrier creams (non-Rx) – prevent friction under soft bands/processors; not drugs per se but part of skin management to maintain device use. Cochlear ProNews
Allergy management (antihistamines) when skin reactivity limits wearing time – selected by pediatrician to improve tolerance; mechanism: H1 blockade; side effects: drowsiness (older agents). NCBI
Antibiotic stewardship – culture-guided choices when infections occur to avoid resistance; ENT/audiology teams set protocols. ScienceDirect
Analgesic plans for staged reconstructions – tailored to each stage (framework harvest, placement, elevation); goal: adequate pain control while minimizing opioids. ScienceDirect
Post-op opioid sparing – if opioids are used, they’re brief and strictly supervised; non-opioid multimodal analgesia is emphasized to reduce side effects. ScienceDirect
Topical antibiotic–steroid combos (short course) – very selective use for inflamed, colonized skin near processors per clinician. PubMed
Vaccinations and routine pediatric meds – not specific to anotia but essential for overall health; keeping up with vaccines (e.g., rubella immunity pre-pregnancy for prevention in future pregnancies) is part of comprehensive care planning. PMC
Dietary molecular supplements
Important honesty note: No supplement treats or reverses anotia. Nutrition matters mainly for future pregnancies (prevention) and general child health.
Folic acid (preconception & early pregnancy) – Strongest link to reduced risk of microtia/anotia; typical 400 μg/day for people who could become pregnant; higher (4 mg/day) may be advised preconception in high-risk diabetes/previous NTD history—follow local guidance. Mechanism: supports DNA synthesis and embryonic cell proliferation during organogenesis. CDC+1
Balanced prenatal multivitamin (within safe vitamin A limits) – Ensures folate, iodine, iron, and B vitamins without excess retinoids, which are teratogenic in high doses. Mechanism: supports normal embryonic development while avoiding harmful excesses. PMC
Iodine (as part of prenatal) – Supports fetal neurodevelopment; follow national guidelines for dose (often 150 μg/day in prenatal vitamins). Mechanism: thyroid hormone synthesis. (General prenatal guidance; not specific to anotia.) NCBI
Iron (when deficient) – Prevents maternal anemia and supports fetal development; dose individualized after ferritin/hemoglobin checks. Mechanism: hemoglobin synthesis/oxygen delivery. (General prenatal health.) NCBI
Folate-rich foods (leafy greens, legumes, citrus) – Food sources that complement folic-acid supplementation for those planning pregnancy. Mechanism: dietary folates enter one-carbon metabolism. CDC
Whole-grain pattern emphasizing complex carbohydrates – Low carbohydrate and low folate patterns have been associated with microtia/anotia risk; balanced diets help meet folate targets. Mechanism: provides B-vitamins and energy substrate. CDC
Omega-3s from food (fish within mercury guidance) – General support for maternal health and fetal neurodevelopment; choose low-mercury options per country guidance. (Adjunctive, not disease-specific.) NCBI
Vitamin D (if deficient) – Routine prenatal care checks can guide supplementation; supports bone and immune health. (General health, not anotia-specific.) NCBI
Protein-adequate diet – Supports wound healing if surgery is planned later; ensure sufficient high-quality proteins. (Perioperative nutrition principle.) ScienceDirect
Hydration and fiber – Reduces postoperative constipation if pain meds are used; supports overall recovery. (General surgical care.) ScienceDirect
Immunity-booster / regenerative / stem-cell drugs
Critical clarity: There are no approved “regenerative drugs” or stem-cell medicines that rebuild a missing ear in clinical practice today. Research is ongoing into tissue-engineered cartilage frameworks and 3D-printed scaffolds, often using a patient’s own cells, but these remain specialized and evolving; clinical standards are still autologous rib cartilage or porous polyethylene (PPE) frameworks. ScienceDirect+1
Tissue-engineered auricular cartilage (research stage) – Lab-grown cartilage seeded on scaffolds; goal: lifelike shape without rib harvest; not routine care yet; dosing doesn’t apply. Mechanism: chondrocyte/MSC matrix deposition on 3D scaffold. PMC
3D-printed biodegradable scaffolds (research stage) – Patient-specific ear shapes printed, then seeded with cells; still investigational; no approved “drug” dosing. Mechanism: guided tissue formation as scaffold resorbs. PMC
Biologic coatings/growth-factor matrices (research stage) – Aims to improve integration/vascularization of implant frameworks; investigational only. PMC
Porous polyethylene (PPE) framework (device, not a drug) – A permanent biocompatible implant; chosen for earlier reconstruction timelines; requires soft-tissue coverage; not a “medicine.” ScienceDirect+1
Autologous rib-cartilage framework (surgical graft, not a drug) – Uses the child’s own cartilage; excellent biocompatibility and durability; again, not a medicine. ScienceDirect
Osseointegrated hearing implants (device) – Titanium implants transmit sound via bone; these are medical devices, not drugs. PubMed
Surgeries
Autologous rib-cartilage auricular reconstruction
Procedure: Surgeons harvest costal cartilage, carve a 3D ear framework, and place it beneath local skin; later stages elevate and refine the ear.
Why: Time-tested, durable, living tissue with low long-term exposure risk; excellent long-term results in experienced hands. ScienceDirectPorous polyethylene (Medpor/PPE) auricular reconstruction
Procedure: A preformed or custom PPE framework is covered with vascularized tissue and skin grafts; may be done earlier than rib methods.
Why: Avoids rib harvest and can be earlier; trade-offs include higher rates of infection/framework exposure in some series and possible redo surgery. PubMed+1Canal atresia surgery (atresiaplasty)
Procedure: Creates/opens an ear canal and reconstructs the eardrum/ossicles (when anatomy allows).
Why: For selected candidates, improves air-conduction hearing; requires careful selection and long-term canal care to prevent restenosis or infections. NCBIBone-anchored hearing implant surgery
Procedure: Places a percutaneous or transcutaneous implant that couples to a processor.
Why: Delivers consistent bone-conduction hearing; preferred solution when canal anatomy is unfavorable for durable atresiaplasty results. PubMedRevision/refinement procedures
Procedure: Addresses contour issues, projection, or complications (exposure, infection).
Why: To optimize appearance and durability across childhood/adolescence. ScienceDirect

When to see a doctor
Immediately after birth to arrange audiology and ENT assessment—even if your baby turns to sounds. Early access to sound is time-sensitive for speech development. NCBI
If devices are not worn consistently (hours per day), or skin is sore under bands/processors. Troubleshoot early. Cochlear ProNews
If there are recurrent ear infections after canal surgery—prompt treatment prevents scarring. NCBI
Before school transitions to update accommodations and remote-microphone plans. NCBI
When considering reconstruction, meet a craniofacial team experienced in both rib-cartilage and PPE techniques to compare options. ScienceDirect
What to eat and what to avoid
Eat: Folate-rich foods (spinach, beans, lentils, citrus), whole grains, lean proteins, iron-rich foods, iodine via prenatal vitamins (per guidance), fruits/vegetables, and adequate fluids—especially if planning future pregnancy or preparing for surgery. These support general health, healing, and evidence-based prevention (folate). CDC+1
Avoid: High-dose vitamin A/retinoid products, alcohol, and non-prescribed supplements in pregnancy; avoid extreme low-carb/low-folate diets; and avoid teratogenic medications unless a specialist confirms safety. PMC+1
Frequently asked questions
Can medicine fix anotia?
No. Medicines help with surgery, skin care, or infections, but no drug regrows an ear. Hearing and reconstruction strategies provide the functional and cosmetic solutions. NCBIWill my child be able to hear?
Many children hear well with bone-conduction devices (soft-band or implanted when older). The inner ear is often normal; the issue is sound conduction. PubMedIs reconstruction required?
No. It’s an elective choice based on family preference, child readiness, and local expertise. Prosthetics are an alternative. ScienceDirectWhich reconstruction is “best,” rib or Medpor?
Both can look excellent in expert hands. Evidence suggests PPE may have higher infection/exposure/redo rates in some series; outcomes and satisfaction vary by center and surgeon experience. Consult teams who offer both. PubMed+1When is the right age for reconstruction?
Timelines differ (PPE often earlier; rib frameworks later when enough cartilage is available). Your team will balance growth, school/social timing, and safety. ScienceDirectIs canal surgery (atresiaplasty) better than a bone-anchored implant?
It depends on anatomy. Selected patients benefit from canal surgery; many do best with bone-anchored hearing for reliable access. NCBICan anotia be prevented?
Not always. But avoiding isotretinoin/teratogens, optimizing diabetes, achieving healthy BMI, and taking folic acid before pregnancy lower risk. CDC+1Does folic acid really help?
Yes. Large studies show lower odds of microtia/anotia with daily folate use. Start before conception if possible. PMCIs anotia part of a syndrome?
Sometimes. A craniofacial/genetics team checks for features of hemifacial microsomia/Goldenhar and others to guide screening. PMCWill my child need special school support?
Usually yes—preferential seating, remote-mics, and teacher training make a big difference. NCBIHow common is microtia–anotia?
Prevalence varies worldwide; surveillance shows notable geographic differences across programs—anotia is the rarest, most severe form. CDC StacksDo we need ongoing scans?
Imaging is used when planning canal surgery or investigating anatomy; your team will time CT to minimize radiation while getting the right information. NCBIAre stem-cell ear replacements available now?
Not as routine care. Tissue engineering is advancing, but current standards remain rib cartilage or PPE frameworks. PMCWhich hearing brand is best?
What matters most is consistent access to sound, good fitting by pediatric audiology, and features your child will actually wear all day. Clinics follow candidacy protocols for bone-conduction systems. Cochlear ProNewsWhere do I start?
Start with an audiology + ENT visit, get a soft-band trial if needed, meet a craniofacial team to learn about reconstruction options, and set up speech-language therapy and school accommodations early. NCBI
