Hypothyroidism and Cleft Palate Syndrome

Hypothyroidism and cleft palate syndrome is a rare genetic condition in which a baby is born with an under-active or missing thyroid gland (congenital hypothyroidism) and a cleft in the roof of the mouth (cleft palate). Doctors often call it Bamforth-Lazarus syndrome. It usually happens when both copies of a gene called FOXE1 do not work properly. Children can also have other features such as choanal atresia (blocked back of the nose) or a bifid epiglottis. Early thyroid treatment and a coordinated cleft team plan help protect growth, brain development, feeding, speech, and hearing. Orpha+2NCBI+2

Some babies are born with two problems at the same time:

• Their thyroid gland does not make enough thyroid hormone. This is called congenital hypothyroidism. Thyroid hormone is important for brain growth, body growth, and energy.

• They also have a cleft palate, which means the roof of the mouth has a gap because the tissues did not join fully during pregnancy. This gap can make feeding, ear health, and speech harder.

These two problems can happen together by chance. But sometimes they are linked by one underlying cause, like a change in a gene that affects both thyroid and palate development. For example, changes in the FOXE1 gene can cause a rare syndrome with congenital hypothyroidism, cleft palate, and spiky hair (Bamforth-Lazarus syndrome). Orpha+1

Doctors confirm congenital hypothyroidism with blood tests (high TSH, low free T4) after newborn screening, and they confirm a cleft palate by looking and gently feeling the palate. Early treatment with levothyroxine helps protect brain development, and early cleft care helps feeding, speech, and hearing. Liebert Publishing+2PMC+2

Other names

• “Congenital hypothyroidism with cleft palate”

• “Bamforth-Lazarus syndrome” (when FOXE1 is the cause; often also spiky hair) Orpha

• “PAX8-related congenital hypothyroidism” (some families; thyroid underdevelopment; cleft palate sometimes present or part of a broader picture) PMC+2PMC+2

• “Syndromic cleft palate with thyroid dysfunction” (for example, in some children with 22q11.2 deletion). NCBI+1

Types

1) By cause: linked (same cause) vs. coincidental (separate causes).

• Linked: One gene change affects both structures. FOXE1 is the classic example, where palate formation and thyroid development both depend on this gene. A single mutation can lead to both findings in the same child. PubMed

• Coincidental: A child happens to have a cleft palate for one reason (for example a multifactorial cleft) and congenital hypothyroidism for another reason (for example thyroid dyshormonogenesis). NIDCR+1

2) By thyroid problem:

• Thyroid dysgenesis (the gland is missing, small, or in the wrong place). This is a common reason for congenital hypothyroidism. American Thyroid Association

• Dyshormonogenesis (the gland exists, but steps to make hormone are faulty due to gene mutations—such as TG, TPO, SLC5A5/NIS, SLC26A4/Pendred, DUOX2/DUOXA2, IYD). PMC

3) By cleft pattern:

• Isolated cleft palate (only the palate is split).

• Cleft lip with cleft palate (lip and palate split together). Both arise from tissue not joining fully before birth. Mayo Clinic

Causes

1. FOXE1 gene changes (Bamforth-Lazarus syndrome).
   FOXE1 helps shape both the thyroid and the palate in the embryo. When both copies of the gene are not working properly, a baby can be born with congenital hypothyroidism and a cleft palate (often with “spiky hair”). Orpha+1

2. PAX8 gene changes.
   PAX8 is a key thyroid “master switch.” Changes can cause thyroid underdevelopment and congenital hypothyroidism; in some families, other features may occur and, rarely, a cleft can be present as part of a broader picture. PMC+1

3. TSH receptor (TSHR) gene changes.
   If the thyroid cannot “hear” TSH signals well, the gland may not grow or make enough hormone. This leads to congenital hypothyroidism; cleft palate may co-occur if there is a separate cleft cause.

4. Thyroglobulin (TG) gene defects.
   TG is the protein “scaffold” for hormone production. Defects mean the gland cannot build T4/T3 properly, leading to congenital hypothyroidism. PMC

5. Thyroid peroxidase (TPO) defects.
   TPO helps attach iodine to TG. If TPO fails, the gland cannot make hormone well. Babies may be hypothyroid at birth. PMC

6. Sodium–iodide symporter (SLC5A5/NIS) defects.
   The thyroid must pull iodine from blood. If this “pump” fails, iodine cannot enter cells, so hormones cannot form. PMC

7. Pendred syndrome (SLC26A4/PDS).
   This genetic condition affects inner ear and thyroid iodine handling. It can cause dyshormonogenesis and goiter. A cleft palate can still be present for other reasons. PMC

8. DUOX2 and DUOXA2 defects.
   These genes help make hydrogen peroxide, a needed “helper” in hormone synthesis. Defects reduce hormone output. PMC

9. IYD (DEHAL1) defects.
   This gene helps recycle iodine inside thyroid cells. If recycling fails, iodine supply runs low and hormone making drops. PMC

10. Thyroid dysgenesis from unknown genetic/environmental factors.
    Sometimes the thyroid is missing, tiny, or ectopic with no single known gene identified. This is a major cause of congenital hypothyroidism. American Thyroid Association

11. 22q11.2 deletion syndrome.
    This syndrome can include facial differences, palatal problems (including cleft), immune issues, and endocrine problems, including thyroid dysfunction in some patients. NCBI+1

12. Stickler syndrome or Pierre Robin sequence (as part of a syndromic cleft).
    These are well-known syndromic causes of cleft palate. Thyroid problems are not core features but can co-occur. PMC+1

13. Chromosomal or copy-number changes beyond 22q11.2.
    Other rare deletions/duplications can disturb organ development. A child may have both cleft palate and thyroid issues as part of a broader pattern.

14. Maternal iodine deficiency.
    If a pregnant parent has very low iodine intake, the fetus cannot build normal thyroid hormone. This can cause congenital hypothyroidism. (Cleft palate has many causes; maternal nutrition is one factor among several.)

15. Maternal iodine excess (rare).
    Too much iodine can paradoxically block the baby’s thyroid (Wolff–Chaikoff effect), lowering hormone production.

16. Maternal antithyroid drugs (like methimazole) during early pregnancy.
    Very early exposure can suppress the fetal thyroid. The risk depends on dose and timing; doctors weigh risks and benefits carefully.

17. Maternal autoimmune thyroid disease with blocking antibodies.
    TSH-blocking antibodies can cross the placenta and reduce fetal thyroid function, causing transient congenital hypothyroidism.

18. Maternal diabetes, obesity, smoking, certain medicines, or alcohol (for the cleft part).
    These exposures raise the risk of a cleft in some studies. A cleft often has more than one contributing factor. Mayo Clinic

19. Multifactorial cleft palate (common path).
    Many clefts arise from a mix of common genes and environmental factors. About 30% of cleft cases are tied to a genetic syndrome; the rest are nonsyndromic. NIDCR

20. Unknown/idiopathic combination.
    In many babies, we never find a single unifying cause. Doctors still treat both problems promptly to protect growth, brain development, feeding, hearing, and speech.

Symptoms

1. Feeding trouble right after birth.
   With a cleft palate, milk can leak into the nose. Babies may cough, choke, or tire easily. Special bottles and positions can help. NCBI

2. Nasal regurgitation.
   Milk comes out of the nose because the palate cannot close the passage between mouth and nose. This improves after surgical repair. NCBI

3. Poor weight gain.
   Feeding takes more effort with a cleft. If hypothyroidism is also present, overall energy is low. Together, these can slow growth.

4. Sleepiness and low energy.
   Babies with hypothyroidism tend to be quiet and sleepy. Early thyroid hormone treatment helps.

5. Constipation.
   Low thyroid slows gut movement. Stools may be infrequent and hard.

6. Cool or dry skin, puffy face, large fontanelle.
   Classic hypothyroid signs in infants include cool/dry skin, facial puffiness, and a soft spot that is larger or closes later.

7. Prolonged newborn jaundice.
   Yellowing of the skin and eyes can last longer than usual in hypothyroid babies.

8. Hoarse cry and enlarged tongue (macroglossia).
   A deep cry and a big tongue are common hypothyroid clues and can also affect feeding.

9. Umbilical hernia.
   A small belly-button bulge is common in hypothyroidism and often harmless.

10. Frequent ear fluid and ear infections.
    The cleft affects how the Eustachian tube works, so fluid collects behind the eardrum. This can reduce hearing if not treated. NCBI

11. Hearing problems.
    Conductive hearing loss can occur from persistent middle-ear fluid. Early hearing checks are important. NCBI

12. Speech sounds that seem nasal or hard to understand (later in childhood).
    A cleft palate can make some sounds hard to form. Speech therapy and surgery help. NCBI

13. Slow growth and delayed milestones if untreated.
    Thyroid hormone is crucial for brain and body development. That is why newborn screening and early treatment are vital. Liebert Publishing

14. Breathing or choking during feeds.
    The open palate can let liquid pass toward the airway. Positioning and special nipples reduce risk. NCBI

15. Facial differences noted at birth.
    Cleft can be obvious when the lip is involved. Isolated cleft palate is sometimes subtler and is found when feeding is hard or during the newborn exam. Mayo Clinic

Diagnostic Tests

A) Physical examination

1. Full newborn exam.
   The clinician inspects the mouth and gently palpates the palate to feel for a split. They also look for signs of hypothyroidism (large fontanelle, puffy face, dry skin, poor tone). This bedside exam starts the work-up. NCBI

2. Growth and nutrition check.
   Weight, length, and head size are measured. Poor weight gain suggests feeding difficulty from the cleft and/or low energy from hypothyroidism.

3. Ear, nose, and throat evaluation.
   The doctor checks for fluid behind the eardrum, nasal airflow, and airway safety during feeds, because cleft palate raises ear and airway risks. NCBI

4. Thyroid palpation and neck exam.
   Sometimes a small, absent, or ectopic thyroid is suspected by a careful neck exam, which guides imaging.

B) Manual/bedside functional assessments

5. Feeding assessment with specialized nipples.
   A lactation or feeding specialist watches the baby feed, tries special bottles, and teaches positions that lower nasal regurgitation and choking. This improves nutrition while waiting for palate repair. NCBI

6. Oral-motor and swallow evaluation.
   A therapist checks how the lips, tongue, and palate move. They look for fatigue and coordination problems and suggest strategies.

7. Speech-language screening (as the child grows).
   Early screening finds resonance (hypernasality) and articulation issues so therapy can start promptly.

8. Developmental screening.
   Because thyroid hormone is key for brain growth, clinicians watch milestones closely, especially if diagnosis or treatment was delayed. Liebert Publishing

C) Laboratory and pathological tests

9. Newborn screening (TSH and/or T4).
   All babies should get screened shortly after birth. Abnormal screening is confirmed with serum tests. Liebert Publishing

10. Serum TSH and free T4.
    High TSH with low free T4 confirms primary hypothyroidism. This test also helps titrate therapy. Liebert Publishing

11. Thyroglobulin (TG) level.
    A very low TG can suggest athyreosis (no thyroid tissue). Detectable TG suggests there is some thyroid tissue present.

12. Thyroid autoantibodies (TPOAb, TgAb, TSH-receptor antibodies).
    These help identify maternal antibody effects or future autoimmune risk.

13. Serum iodine or urinary iodine (context-dependent).
    These assess iodine status when diet or geography raises concern.

14. Genetic testing panels for congenital hypothyroidism.
    Panels may include FOXE1, PAX8, TSHR, TG, TPO, SLC5A5, SLC26A4, DUOX2/DUOXA2, IYD, and others. Results can explain cause, guide counseling, and, in some cases, clarify why cleft and hypothyroidism co-occur. PMC

15. Syndrome-focused genetic testing or microarray.
    If the child has facial features, heart findings, immune problems, or palate issues that suggest a syndrome, tests like chromosomal microarray can look for 22q11.2 deletions or other copy-number changes. NCBI

D) Electrodiagnostic tests

16. Auditory Brainstem Response (ABR) / newborn hearing screening.
    Cleft palate increases middle-ear fluid and hearing risk. ABR objectively checks hearing in infants so ear tubes or other care can be planned early. NCBI

17. Electrocardiogram (ECG) if bradycardia is suspected.
    Severe hypothyroidism can slow the heart. ECG confirms rhythm and rate so treatment is adjusted if needed.

E) Imaging and endoscopic tests

18. Thyroid ultrasound.
    This painless scan shows if the gland is present, small, or ectopic (in an unusual place). It also helps distinguish dysgenesis from dyshormonogenesis. American Thyroid Association

19. Radionuclide thyroid scan (scintigraphy).
    A tiny, safe tracer pictures thyroid tissue and uptake. It helps find an ectopic gland and suggests whether hormone-making steps work. Liebert Publishing

20. Nasendoscopy or video naso-pharyngoscopy (ENT).
    A very thin camera looks at the soft palate movement and the back of the nose. This helps plan surgery and later speech therapy. NCBI

Non-pharmacological treatments (therapies & others)

1. Cleft/craniofacial team care (the hub of management).
   Purpose: coordinate surgery, speech, feeding, hearing, dental, psychosocial care from birth to adulthood.
   Mechanism: team reviews growth, airway, sleep, feeding, ears, teeth, and speech at scheduled intervals; creates a sequenced plan (e.g., palatoplasty, ear tubes, orthodontics, bone graft). Evidence-based “Parameters of Care” guide timing and quality checks. ACPA+1

2. Early newborn thyroid replacement education for parents.
   Purpose: ensure correct daily dosing, spacing from iron/calcium/soy, and adherence.

3. Feeding support & positioning.
   Purpose: help babies with cleft palate feed safely and gain weight.
   Mechanism: lactation specialists and feeding therapists teach upright positioning, paced feeding, and nipple choices; evidence shows specialized bottles/obturators may not always improve growth versus standard methods, so coaching focuses on cues and technique. PubMed+2Cochrane+2

4. Speech-language therapy (resonance & articulation).
   Purpose: improve speech clarity and reduce hypernasality after palate repair.
   Mechanism: targeted articulation therapy and airflow control; distinguish learned errors (need therapy) from structural velopharyngeal insufficiency (may need surgery/obturator). ASHA Publications+1

5. Palatal obturator or speech bulb (when surgery is delayed/insufficient).
   Purpose: temporarily reduce nasal air escape to improve speech and feeding.
   Mechanism: a custom dental device lifts or fills the gap at the soft palate to help closure during speech and swallowing; appropriate for selected patients per SLP/cleft team. ASHA Apps

6. Audiology monitoring & early ear care.
   Purpose: detect and treat fluid-related hearing loss that is common with cleft palate.
   Mechanism: periodic hearing tests; otolaryngology follow-up; timely tympanostomy tubes reduce middle-ear effusion burden and support speech/language development. njcraniofacialcenter.com

7. Orthodontic guidance & maxillary expansion (prior to bone graft).
   Purpose: align teeth and prepare the dental arch for alveolar cleft grafting.
   Mechanism: staged orthodontics in mixed dentition improves graft access and tooth eruption paths; typical timing just before permanent incisors/canines erupt. PubMed+1

8. Nutritional counseling (iodine-aware).
   Purpose: ensure enough iodine for thyroid hormone production in pregnancy and lactation, and adequate calories/protein for child growth.
   Mechanism: dietitian supports iodized-salt use and food sources (fish, dairy, eggs) within local guidelines; avoids unnecessary high-dose supplements. Office of Dietary Supplements

9. Developmental follow-up & early intervention.
   Purpose: monitor milestones and provide physical/occupational/early education therapies if needed.

    Purpose: safer, smoother palate surgery recovery.
    Mechanism: standardized pre-/post-op medications, pain control, and feeding protocols reduce complications and hospital stay. Children’s Hospital of Orange County

15. Hearing protection & otitis media prevention education.
    Purpose: reduce ear infections that worsen hearing/speech outcomes.
    Mechanism: vaccination per schedule, smoke-free home, prompt care for otitis; coordinated with ENT. njcraniofacialcenter.com

16. School-based accommodations (IEP/SLP).
    Purpose: support learning and speech practice in class.
    Mechanism: SLP services and classroom strategies for articulation/resonance build communication success. ASHA Publications

17. Adolescent transition planning.
    Purpose: handover from pediatric to adult endocrinology/craniofacial teams.
    Mechanism: structured education on lifelong levothyroxine use, pregnancy planning, and oral health. PMC

18. Pregnancy counseling for mothers with hypothyroidism.
    Purpose: optimize maternal thyroid levels to protect fetal development.

Drug treatments

Important clinical reality: For hypothyroidism (including congenital forms), the standard of care is levothyroxine (T4). Only a small number of thyroid drugs are FDA-approved and relevant; there are not 20 different appropriate drugs for this condition. Below, I list the most important, with FDA labeling sources and plain-English details.

1) Levothyroxine tablets (e.g., Synthroid®, LEVO-T®, Unithroid®).
Class: synthetic T4.
Dose/Time: infants require higher mcg/kg/day than older children; adults average ~1.6 mcg/kg/day; give once daily on an empty stomach; separate from iron/calcium/soy.
Purpose/Mechanism: replaces T4 so the body can convert to T3 in tissues and normalize TSH.
Side effects: over-replacement causes symptoms of hyperthyroidism (fast heart rate, irritability, weight loss); under-replacement leaves fatigue/cold intolerance. (Follow TSH/FT4.) FDA labels cover indications from neonatal to adult. FDA Access Data+1

2) Levothyroxine oral solution (Tirosint-SOL®).
Class: synthetic T4 oral solution.
Dose/Time: same mcg/kg/day targets; useful when swallowing tablets is difficult or absorption is an issue; once daily away from binding foods/supplements.
Purpose/Mechanism: liquid form can reduce excipient issues and variability; restores euthyroidism.
Side effects/Notes: same as tablets; label stresses full-replacement dosing in significant hypothyroidism and pregnancy-specific TSH targets. FDA Access Data+1

3) Levothyroxine injection (IV).
Class: synthetic T4 for IV use.
Dose/Time: used when oral absorption isn’t possible (e.g., myxedema coma, NPO); dosing guided by label and specialist protocols.
Purpose/Mechanism: provides systemic T4 directly; converted to T3 peripherally.
Side effects: risk of overtreatment and cardiac strain if dosed too high; reserved for hospital care. FDA Access Data

4) Liothyronine tablets (Cytomel®, T3).
Class: synthetic T3.
Dose/Time: small doses given in divided schedule due to short half-life; not first-line for routine congenital hypothyroidism.
Purpose/Mechanism: directly supplies T3, which is the active hormone in tissues; sometimes used for diagnostic suppression tests or specific scenarios.
Side effects: higher risk of palpitations/arrhythmias if overused; labels list classic contraindications (untreated adrenal insufficiency, thyrotoxicosis). FDA Access Data+1

5) Combination therapy (T4 + T3).
Class: dual hormone replacement.
Dose/Time: individualized, specialist-only; evidence is mixed; no fixed-dose combo with pediatric labeling dominates care.
Purpose/Mechanism: attempts to mimic physiologic T4-to-T3 balance.
Notes: many guidelines still recommend T4 monotherapy as standard; use only with endocrinology input. (Guideline context.) PMC

6) Animal-derived (desiccated) thyroid products (DTE).
Status: not FDA-approved; FDA announced intentions (Aug 2025) to act against marketed unapproved animal-derived thyroid products; ATA reaffirms levothyroxine as standard.
Purpose/Mechanism: contain variable T4/T3 ratios; potency consistency is a concern.
Clinical use: avoid in congenital hypothyroidism; stick to FDA-regulated levothyroxine. U.S. Food and Drug Administration+2U.S. Food and Drug Administration+2

(Those are the evidence-based drug options. Listing “20 drugs” would be misleading; the safe, FDA-labeled choice for almost all patients is levothyroxine.)

Dietary molecular supplements

Safety note: Thyroid replacement is the primary therapy. Supplements can help only when a true deficiency exists. Avoid high-dose products that interfere with levothyroxine absorption (iron, calcium, soy) near the dosing time.

1. Iodine (RDA-guided).
   Function/Mechanism: essential building block of T4/T3; supports thyroid hormone synthesis in pregnancy/lactation.
   Dose: follow national RDA (e.g., adults ~150 µg/day; pregnancy/lactation higher).
   Use: dietary iodized salt/foods preferred; avoid megadoses. Office of Dietary Supplements

2. Selenium.
   Function: cofactor for deiodinase enzymes converting T4→T3; antioxidant roles.
   Dose: stick to RDA (excess can be toxic); evidence for routine supplementation in thyroid disease is mixed. Office of Dietary Supplements

3. Iron (only if deficient).
   Function: iron-dependent enzymes support thyroid function; deficiency worsens hypothyroid symptoms.
   Dose: as prescribed; separate from levothyroxine by several hours to avoid absorption problems. FDA Access Data

4. Calcium (only if needed).
   Function: bone health; not a thyroid treatment.
   Dose: per dietary needs; take several hours apart from levothyroxine. FDA Access Data

5. Vitamin D.
   Function: bone and immune support in growing children; common deficiency may coexist.
   Dose: per labs and pediatric guidance; not a substitute for thyroid hormone. njcraniofacialcenter.com

6. Zinc (if deficient).
   Function: supports taste, appetite, and enzyme systems; deficiency can mimic hypothyroid symptoms.
   Use conservatively; avoid high doses without testing. Office of Dietary Supplements

7. Omega-3 fatty acids (nutrition focus).
   Function: general anti-inflammatory nutrition; not a thyroid treatment but part of balanced diet.
   Use foods (fish, nuts) first; supplements only if diet is inadequate. Office of Dietary Supplements

8. B-complex (only if deficient).
   Function: energy metabolism; certain B-vitamin deficits can worsen fatigue.
   Use targeted replacement, not megadoses. Office of Dietary Supplements

9. Probiotic foods (yogurt/kefir).
   Function: gut health and antibiotic-associated diarrhea reduction; no direct thyroid effect.
   Use as part of varied diet. Office of Dietary Supplements

10. Protein-rich foods/medical nutrition support (when growth falters).
    Function: supports catch-up growth with feeding challenges.
    Use: dietitian-led plan; supplements as needed to meet calories/protein. PMC

Immunity-booster / regenerative / stem-cell–type” therapies

Key safety message: There are no approved stem-cell drugs for hypothyroidism or cleft palate. Some bone-regeneration biologics are FDA-approved for specific uses and sometimes considered by surgeons; many pediatric cleft uses are off-label and should be discussed carefully with your team.

1. rhBMP-2 (INFUSE® Bone Graft) – device/biologic for bone regeneration.
   Use: FDA-approved for certain spine and oral/maxillofacial indications (e.g., sinus and localized ridge augmentation), not specifically for pediatric alveolar clefts; some centers use it off-label in cleft alveolar grafting. Evidence shows comparable bone fill to iliac crest graft in selected studies, but swelling and other risks exist. ScienceDirect+3FDA Access Data+3FDA Access Data+3

2. rhBMP-2 + synthetic scaffolds (e.g., HA/TCP) – off-label in cleft care.
   Rationale: reduce donor-site morbidity; early studies suggest similar bone levels to autograft. Decision is individualized by surgeon and family. Lippincott Journals

3. Platelet-rich fibrin/platelet concentrates (adjunct).
   Status: autologous biologic adjunct studied for bone healing; protocols vary; not a drug; evidence evolving. Discuss risks/benefits with surgical team. MDPI

4. Mesenchymal stem-cell–based constructs (research).
   Status: experimental in craniofacial bone; no FDA-approved stem-cell drug for cleft bone grafting in children. Consider only within research protocols. MDPI

5. Vaccination & routine pediatric immunizations.
   Not a “booster pill,” but essential to reduce respiratory/ear infections that worsen hearing and speech outcomes after palatoplasty. Follow national immunization schedules. njcraniofacialcenter.com

6. Micronutrient repletion when deficient (iodine, iron, selenium).
   These are not immune boosters but correcting documented deficiencies supports normal physiology and recovery. Use RDAs and lab-guided dosing. Office of Dietary Supplements+1

Surgeries (procedures & why they’re done)

1. Palatoplasty (primary cleft palate repair).
   Procedure: closes the cleft in the palate, usually around 8–12 months in many programs (often before 18 months), to enable normal speech development and feeding.
   Why: to separate oral/nasal cavities, improve speech potential, and reduce regurgitation. PMC+1

2. Tympanostomy tubes.
   Procedure: tiny ear tubes placed to ventilate the middle ear and reduce fluid buildup.
   Why: children with cleft palate have high rates of otitis media with effusion; tubes help protect hearing during key speech-language years. njcraniofacialcenter.com

3. Secondary VPI surgery (e.g., superiorly based pharyngeal flap or sphincter pharyngoplasty).
   Procedure: narrows the velopharyngeal gap to reduce hypernasal speech.
   Why: when therapy alone cannot fix structural velopharyngeal insufficiency after palatoplasty. Studies show improved resonance in well-selected patients. PMC+1

4. Secondary alveolar bone graft (SABG).
   Procedure: bone (often from iliac crest) is grafted into the alveolar cleft in mixed dentition, timed to support tooth eruption.
   Why: stabilizes the dental arch, closes oronasal fistula, and supports canine eruption; timing typically before central incisors/canines erupt. PubMed+1

5. Orthognathic or nasal revision procedures (select cases).
   Procedure: jaw or nasal surgeries in adolescence/young adulthood.
   Why: correct occlusion, improve airway, or refine nasal symmetry for function and appearance after growth. PMC

What to eat & what to avoid

Eat more of:

• Iodine-containing foods (fish, dairy, eggs) within dietary guidance; iodized salt if recommended locally. Office of Dietary Supplements

• Balanced calories & protein to support growth, using dietitian guidance if feeding is difficult. PMC

Avoid or separate from levothyroxine:

• Iron or calcium supplements and calcium-rich antacids: take several hours after levothyroxine.

• Soy formulas or large soy intakes near the levothyroxine dose.

• High-fiber or coffee right with the pill in older patients (can reduce absorption). (Follow your label’s timing rules.) FDA Access Data

Frequently asked questions

1. Is this condition curable?
   The cleft palate is repaired with surgery; congenital hypothyroidism needs lifelong thyroid hormone in most cases. With early, steady treatment, children can grow and learn well. Pediatrics Publications

2. What causes it?
   Most often FOXE1 gene changes inherited from both parents (autosomal recessive). A genetic team can explain your family’s risk. NCBI

3. Will my baby be found on newborn screening?
   Yes, congenital hypothyroidism is part of standard newborn screening in many countries; it enables early treatment. Pediatrics Publications

4. Why is levothyroxine preferred?
   It’s FDA-regulated, stable, converts to T3 in tissues, and has the best safety/efficacy profile across ages. FDA Access Data

5. Can I use “natural” thyroid (desiccated)?
   No—these products are not FDA-approved and have variable potency; FDA is moving against unapproved animal-derived thyroid products. U.S. Food and Drug Administration+1

6. What about adding T3?
   Liothyronine (T3) has FDA labeling, but routine combination therapy isn’t standard and needs specialist oversight. FDA Access Data

7. How is palatoplasty timed?
   Many teams repair the palate before 18 months (often around 8–12 months) to support speech. Your team adjusts timing for your child. PMC

8. Will my child need ear tubes?
   Often yes—cleft palate raises the risk of chronic ear fluid; tubes protect hearing during language development. njcraniofacialcenter.com

9. What if speech stays hypernasal after repair?
   SLP therapy continues; if a structural gap persists, procedures like a pharyngeal flap can improve resonance. PMC

10. When is the bone graft done?
