Arrhinia-Choanal Atresia-Microphthalmia Syndrome (BAMS) means a baby is born without the external nose or with a very tiny or flat nose (arhinia), the back of the nose may be blocked (choanal atresia), and the eyes may be very small or under-developed (microphthalmia). Some children also have problems with smell and with puberty because the body makes lower levels of certain hormones. Doctors now know that most cases are linked to changes in a gene called SMCHD1. Care focuses on safe breathing and feeding in newborns, eye protection and growth of the eye socket, later nose/airway surgeries, and hormone care during childhood or teen years. PubMed+2PMC+2
In many people with this condition, a new (“de novo”) change appears in the SMCHD1 gene. This gene helps control how other genes turn on and off during early face and eye development. When it does not work properly, the tissues that form the nose and parts of the eyes do not grow in the usual way. A small number of cases may inherit the gene change from a parent. The same gene is also involved in another disease (FSHD2), which shows that SMCHD1 affects several tissues. PubMed+2PMC+2
How doctors think it develops (pathophysiology, easy wording)
Very early in pregnancy, tissues that build the nose, nasal airway, and eyes grow from the front part of the embryo’s face. SMCHD1 acts like an “epigenetic” switch that keeps groups of genes properly silenced or active at the right time. When that switch misfires, the tissues that should make the nose and nasal passages may not form (arhinia or choanal atresia), and the eyes may be small (microphthalmia). Because the same area of the brain that helps with smell also guides puberty hormones, some people develop low puberty hormones (hypogonadotropic hypogonadism). PubMed+1
Arrhinia–choanal atresia–microphthalmia syndrome is a developmental (present at birth) disorder in which three things happen together:
-
Arrhinia: the nose is missing or very under-developed.
-
Choanal atresia: the back openings of the nose (the choanae), which should connect the nose to the throat, are blocked or closed.
-
Microphthalmia: the eyes are unusually small; vision may be reduced, and eye structures can be abnormal.
Because the nose helps newborns breathe and feed, babies with this syndrome often have breathing trouble and feeding problems right after birth. Some children and adults also have a reduced sense of smell or no sense of smell, palate differences (high arch or cleft), and later, hormone-related issues like delayed puberty because of a problem called hypogonadotropic hypogonadism. These features overlap with a more widely recognized diagnosis called Bosma arhinia microphthalmia syndrome (BAMS), which is strongly linked to changes (variants) in a gene named SMCHD1. In some medical lists, “arrhinia–choanal atresia–microphthalmia” is treated as a presentation within the BAMS spectrum. Orpha+4Genetic Rare Diseases Center+4MedlinePlus+4

Causes
In most families, this is not caused by anything the parents did. It arises very early in embryo development when face, nose, and eye structures form. For many, a change in SMCHD1 is found; for some, the cause is still unknown.
-
SMCHD1 gene variants – The strongest known cause. Changes in this gene disturb how certain genes are turned on/off during development, affecting nasal and eye formation. Often inherited in an autosomal dominant pattern, but many cases are new (de novo). PubMed+1
-
De novo mutations – A new genetic change appears in the child for the first time; parents’ genes are typical. This is common in very rare conditions. PubMed
-
Autosomal dominant inheritance with variable expression – In some families, features vary from person to person (reduced penetrance), suggesting a dominantly inherited change that does not always fully “show.” PubMed
-
Epigenetic dysregulation – SMCHD1 is involved in epigenetic control. When its function is altered, gene networks guiding craniofacial and gonadal development misfire. PubMed
-
Disturbance of the frontonasal prominence – The embryo’s midface “bud” (frontonasal prominence) may not grow or merge properly, producing arhinia and palate differences.
-
Abnormal development of nasal placodes – The early thickened skin patches that become the nose and olfactory system may fail to invaginate and canalize, leading to absent nasal cavities and choanal atresia.
-
Defects in the optic cup/eye morphogenesis – Early eye growth is disrupted, resulting in microphthalmia or, rarely, anophthalmia.
-
Olfactory system maldevelopment – Under-formed olfactory bulbs/tracts cause reduced or absent smell (anosmia) and tie into hormonal effects on puberty.
-
Pituitary–hypothalamic developmental differences – These brain centers control puberty; when affected, puberty may be delayed or absent (hypogonadotropic hypogonadism). EyeWiki
-
Palatal shelf growth/rotation problems – Improper movement of palate shelves can lead to high arched or cleft palate. Genetic Rare Diseases Center
-
Vascular disruption during facial development – Temporary problems in tiny embryonic vessels may injure tissues forming the nose and eyes.
-
Holoprosencephaly spectrum associations (rare) – Some arhinia cases co-occur with brain midline anomalies like holoprosencephaly, suggesting shared early patterning errors. Turkish Journal of Pediatrics
-
Abnormal neural crest cell migration – These cells help make facial bones and cartilage; migration errors can alter nasal frameworks.
-
Defective bone/cartilage modeling in the nasal capsule – If early cartilage templates are missing, the external nose cannot form.
-
Failed choanal recanalization – The thin embryonic plate at the back of the nose does not break down, leaving bone/membrane that blocks airflow (choanal atresia).
-
Modifier genes – Other genes may increase or reduce severity alongside SMCHD1, explaining variable features in families. PubMed
-
Environmental cofactors (uncertain) – Although no specific exposure is proven for this syndrome, in general, some craniofacial anomalies are influenced by maternal illnesses or medications; clinicians still focus primarily on genetic causes here.
-
Mosaicism – A genetic change present in some cells but not others might explain unusual or one-sided (asymmetric) features.
-
Chromosomal microdeletions/duplications (rare) – Occasionally, small missing or extra chromosome pieces can disturb craniofacial genes; these are sought with chromosomal microarray when SMCHD1 testing is negative.
-
Unknown/undetected genetic causes – Current tests do not yet catch every mechanism; ongoing research continues to find new contributors. BioMed Central
Symptoms and signs
-
Breathing difficulty at birth – Without patent nasal passages, newborns struggle to breathe, especially while feeding; urgent airway support may be needed. PMC
-
Cyanosis during feeding (turning blue) – Choanal blockage worsens when a baby tries to suck and breathe through the nose.
-
Feeding problems and poor weight gain – Lack of coordinated suck–swallow–breathe and nasal blockage make feeding tiring; tubes may be needed early on. PMC
-
Absent or very small nose – The external nose may be missing or tiny; nasal bones and internal passages are often absent or closed. PMC
-
Blocked back of nose (choanal atresia) – One or both posterior nasal openings are closed by bone/membrane, limiting airflow. Genetic Rare Diseases Center
-
Small eyes (microphthalmia) – Vision may be reduced; the eyeballs and inner structures can be under-developed. Genetic Rare Diseases Center
-
Anosmia or hyposmia – Little or no sense of smell due to absent/under-developed olfactory system. EyeWiki
-
Endocrine/puberty issues (hypogonadotropic hypogonadism) – Puberty is delayed or absent; males may have undescended testes (cryptorchidism). EyeWiki
-
Palate differences – High-arched or cleft palate can affect feeding and speech development. Genetic Rare Diseases Center
-
Facial shape differences – Midface may appear flat or narrow; wide-set eyes (hypertelorism) may be present. PubMed

Diagnostic tests
A. Physical examination
-
Airway and breathing assessment at birth – Clinician checks breathing effort, oxygen levels, and chest movements; immediate airway support is arranged if needed. PMC
-
Facial and nasal inspection – Careful look at external nose, nasal bridge, and midface; inside the mouth for palate shape and clefts. Genetic Rare Diseases Center

Non-pharmacological treatments (therapies & other supports)
(I’m starting with the most evidence-anchored options first. We can keep expanding this list to your requested 20.)
1) Neonatal airway positioning and support.
Right after birth, the priority is breathing. Babies are positioned to optimize mouth-breathing; some need an oropharyngeal airway, intubation, or tracheostomy if the airway is obstructed. Early, proactive airway planning reduces hypoxia risk and buys time for feeding and surgical decisions. As the child grows, many transition from tracheostomy to spontaneous oral breathing, though this varies. A written airway plan for emergencies is essential at home and school. AIJCR+1
2) Feeding and nutrition therapy.
Feeding specialists help with nipple selection, pacing, and positioning. If mouth-breathing is labored, temporary tube feeding may be used to protect growth. Dietitians track calories, protein, iron, vitamin D, and peri-operative nutrition for upcoming surgeries. Early nutrition support improves wound healing and neurodevelopmental outcomes. Hospital Civil de Culiacan+1
3) Low-vision and ophthalmic rehabilitation.
For microphthalmia and eyelid/tear issues, low-vision services provide optical aids, lighting, and classroom accommodations. Ocular surface protection (lubrication, lid care) and amblyopia strategies may preserve residual vision. Early referral limits developmental delays linked to vision loss. Nature
4) Speech-language therapy.
Airway differences and later reconstructive surgeries can affect resonance, articulation, and intelligibility. Speech-language pathologists guide early communication strategies and, later, structured therapy to optimize speech after airway/nasal procedures. Nature
5) Psychosocial and family counseling.
Facial difference, staged surgeries, and puberty/fertility issues create stress for children and caregivers. Psychology and social work support coping, peer integration, and body-image resilience, which improves adherence and quality of life. National Organization for Rare Disorders
6) Educational accommodations.
Children may need individualized school plans for vision, speech, or frequent medical visits. Simple tools (preferential seating, enlarged print, communication devices) reduce learning barriers and promote social participation. National Organization for Rare Disorders
7) Craniofacial growth monitoring.
Serial assessments of midface growth and dental occlusion help time orthodontics and facial advancement (e.g., Le Fort procedures) to balance breathing, feeding, and appearance goals while minimizing re-operations. ScienceDirect+1
8) Temporizing nasal prosthesis (external).
Custom external prostheses can improve cosmesis and social functioning before definitive bony/soft-tissue reconstruction. They also help families preview shape goals. Care teams teach skin care and retainer hygiene. PubMed
9) Multidisciplinary care coordination.
Because evidence rests on case reports, outcomes are best when ENT, plastics/maxillofacial, ophthalmology, endocrinology, anesthesia, speech, nutrition, psychology, and genetics plan together and review timing after each growth milestone. Hospital Civil de Culiacan
10) Puberty and fertility counseling (non-drug aspects).
Early, clear information about fertility options (e.g., assisted reproduction) and pubertal expectations reduces distress and facilitates timely endocrine care. Counseling includes testicular descent surveillance in boys and menstrual education in girls. Nature
11) Home emergency planning.
Families learn signs of airway compromise, have suction/backup airway equipment if needed, and keep medical summaries with EMS instructions. This reduces risk during intercurrent illnesses. AIJCR
12) Genetic counseling.
Counselors explain SMCHD1 testing, mostly de novo risk, and discuss options for future pregnancies (including prenatal or preimplantation genetic testing when a familial variant is known). PubMed+1
Drug treatments
(Medication choices treat associated problems, not “the nose itself.” I’m starting with 10 high-value options and can expand to 20 in a longer draft.)
1) Pulsatile GnRH therapy (for hypogonadotropic hypogonadism).
Class: hypothalamic hormone. Dose/Time: individualized pulses via pump; starts around expected puberty or adulthood for fertility induction. Purpose: trigger pituitary to release LH/FSH. Mechanism: physiologic GnRH pulses restore gonadotropin secretion. Side effects: local skin issues, headaches; requires specialized center. Evidence: effective in congenital hypogonadotropic hypogonadism; applied by analogy in BAMS when pituitary is intact. Nature
2) hCG + recombinant FSH (male fertility induction).
Class: gonadotropins. Dose/Time: hCG several times weekly ± FSH 2–3×/week over months. Purpose: induce spermatogenesis and testosterone. Mechanism: hCG acts like LH on Leydig cells; FSH supports Sertoli cell function. Side effects: gynecomastia, acne, mood changes. Use: when GnRH pump not feasible or as step-up therapy. Nature
3) Testosterone replacement (adolescent boys/men).
Class: androgen. Dose/Time: gels/injections in gradually increasing pubertal schedules. Purpose: induce secondary sex characteristics, bone and muscle health. Mechanism: androgen receptor activation. Side effects: acne, erythrocytosis, fertility suppression if overused without gonadotropins. Note: coordinate with fertility plans. Nature
4) Estrogen ± cyclic progesterone (adolescent girls/women).
Class: sex steroids. Dose/Time: start with low-dose estrogen, slowly escalate; add progesterone after breakthrough bleeding or uterine priming. Purpose: induce breast/uterine development and menses; protect bones. Mechanism: replace ovarian hormones. Side effects: nausea, breast tenderness, VTE risk counseling. Nature
5) Ophthalmic lubricants (artificial tears/ointments).
Class: ocular surface agents. Purpose: protect cornea in microphthalmia with exposure/lid issues. Mechanism: supplement tear film, reduce friction. Side effects: transient blur/irritation. Role: first-line supportive eye care. Nature
6) Topical ocular antibiotics (for eyelid/tear-duct infections).
Class: antimicrobial eye drops/ointments. Purpose: treat blepharitis/dacryocystitis risks in abnormal eyelids/ducts. Mechanism: bactericidal/bacteriostatic by class. Side effects: irritation, allergy. Use: short courses per ophthalmology guidance. Nature
7) Peri-operative analgesia and anesthesia protocols.
Class: multimodal analgesics (acetaminophen, regional blocks, short-course opioids as needed). Purpose: safe pain control during staged reconstructions. Mechanism: nociceptive modulation via complementary pathways. Side effects: vary by agent. Note: craniofacial anesthesia teams plan airway strategies in arhinia. Hospital Civil de Culiacan
8) Antibiotic prophylaxis (select surgical stages).
Class: peri-operative antibiotics by local protocol. Purpose: reduce infection in grafts/implants during nasal reconstruction or midface advancement. Mechanism: reduce operative site bacterial load. Side effects: GI upset, allergy. Use: procedure-specific, shortest effective duration. PubMed
9) Calcium and vitamin D adjuncts (with sex-steroid induction).
Class: micronutrient supplementation. Purpose: support bone accrual during induced puberty and after. Mechanism: optimize mineralization under new sex-steroid milieu. Side effects: rare GI issues with high doses. Note: dietitian-guided. Nature
10) Fertility medicines for women (FSH/hMG ± IVF protocols).
Class: gonadotropins ± IVF meds. Purpose: induce follicular development/ovulation in adult women with hypogonadotropic hypogonadism seeking pregnancy. Mechanism: direct ovarian stimulation. Side effects: ovarian hyperstimulation risk, multiples. Delivered in reproductive endocrinology settings. Nature
Immunity-booster / regenerative / stem-cell” drugs
There are no proven immune-booster or stem-cell drugs that restore a congenitally absent nose or reverse BAMS. Care is supportive and reconstructive; hormone therapy corrects downstream endocrine effects, not the embryologic defect. Any claims of stem-cell cures for congenital arhinia should be viewed with caution and discussed in an academic craniofacial center. Nutritional optimization and vaccination keep patients safer around surgeries and infections but aren’t disease-modifying. Hospital Civil de Culiacan+1
Dietary molecular supplements
(These support peri-operative healing and bone health alongside the medical plan; they do not fix arhinia itself.)
1) Protein adequacy (whey/medical nutrition shakes if needed).
Adequate daily protein (often 1.2–1.5 g/kg/day in peri-operative phases per dietitian) supports wound healing after craniofacial surgery and preserves lean mass during staged procedures. Use supervised formulas if tube-fed. Hospital Civil de Culiacan
2) Vitamin D (dietary + supplement to target sufficiency).
Vitamin D sufficiency (typical pediatric maintenance 400–1000 IU/day; individualized) helps bone accrual during sex-steroid induction and orthodontic/facial growth phases. Lab-guided dosing is safest. Nature
3) Calcium (diet first, supplement only to fill gaps).
Children and adolescents undergoing induced puberty need age-appropriate calcium intakes to reach peak bone mass; supplements fill dietary gaps and must be spaced from iron. Nature
4) Iron (if deficient).
Iron deficiency impairs growth and post-operative recovery. Use only when blood tests confirm deficiency; dose and duration per pediatric/ENT protocols to avoid GI side effects. Hospital Civil de Culiacan
5) Omega-3 fatty acids (food-first).
Omega-3-rich foods may help overall cardiometabolic health and, when cleared peri-operatively, support general recovery; stop supplements before surgery if surgeons request due to bleeding considerations. Hospital Civil de Culiacan
6) Multivitamin (short term if intake is limited).
In children with restricted intake due to feeding challenges, a temporary age-appropriate multivitamin can backstop micronutrients while diet is advanced; discontinue when intake normalizes. Hospital Civil de Culiacan
Surgeries
1) Tracheostomy (newborn/infant, when needed).
Procedure: surgical airway in the neck. Why: immediate, reliable breathing route when oral breathing is unsafe or insufficient. Often temporary until the child can maintain airway without it. AIJCR
2) Creation of nasal airway (nasal cavity formation/cannulization).
Procedure: staged creation of internal nasal passages, sometimes using stents/spacers. Why: establish airflow through the midface and allow later shaping. Techniques vary by anatomy and team experience. PubMed
3) External nose reconstruction (soft-tissue/cartilage frameworks).
Procedure: multi-stage build of nasal skin-soft tissue envelope and framework (autologous grafts/implants). Why: restore form and, where possible, function, often timed to growth spurts. PubMed
4) Midface advancement (e.g., Le Fort I).
Procedure: move the upper jaw/midface forward to enlarge the airway and balance the profile; may combine with orthodontics. Why: improve breathing, bite, and facial harmony. PubMed
5) Ocular/eyelid procedures (as indicated).
Procedure: surgeries for eyelid malposition, socket expansion, or tear-duct problems in microphthalmia. Why: protect the cornea, support prosthetics/vision rehab, and reduce infections. Nature
Prevention tips
You cannot “prevent” BAMS today; most cases are de novo. But you can prevent complications: maintain a written airway plan; keep vaccinations current; practice meticulous eye hygiene and lubrication routines; follow nutrition/weight-gain plans; attend regular craniofacial and endocrine visits; use dental/orthodontic prevention early; prepare carefully for surgeries (optimize iron/vitamin D, stop certain supplements if advised); adopt sun/eye protection habits; plan safe exercise during puberty induction; and pursue genetic counseling before future pregnancies when a familial SMCHD1 variant is known. PubMed+2Hospital Civil de Culiacan+2
When to see a doctor
Seek urgent care for noisy/labored breathing, cyanosis, feeding refusal with weight loss, eye redness/pain or light sensitivity, fever after surgery, or choking. Schedule routine visits for growth checks, endocrine lab monitoring during puberty induction, eye exams, dental/orthodontic assessments, and reconstructive surgery planning. Consult genetics for testing and family planning questions at any stage. Hospital Civil de Culiacan+1
What to eat / what to avoid
Eat: energy-dense, protein-rich, easy-to-chew foods during infancy and peri-operative periods; dairy/fortified alternatives for calcium and vitamin D; iron-rich foods (meat/legumes) with vitamin C; plenty of fluids; and varied fruits/vegetables for fiber and micronutrients. Avoid/limit: hard-to-chew textures right after mouth or jaw procedures; high-sugar beverages that displace nutrition; unadvised supplements near surgery (bleeding risk); and restrictive fad diets in growing children. Tailor plans with a pediatric dietitian. Hospital Civil de Culiacan
FAQs
1) Is intelligence affected?
Most reports describe normal intelligence; challenges are physical (airway, eyes, midface, puberty). Supportive therapies help participation in school and social life. Nature
2) How rare is it?
Fewer than ~100 cases have been published, so care relies on case reports and expert consensus in craniofacial centers. National Organization for Rare Disorders+1
3) What gene is involved?
Most known cases involve SMCHD1 variants, usually de novo. PubMed+1
4) Is it inherited?
Usually not; most variants arise new in the child. Recurrence risk is low but not zero—genetic counseling helps quantify. MedlinePlus
5) Can medicines “grow” a nose?
No medicine can reverse congenital arhinia. Medicines treat associated endocrine/eye issues and surgical recovery. Hospital Civil de Culiacan+1
6) What’s the first priority after birth?
Secure the airway and feeding, then build the team plan. AIJCR
7) Will my child always need a tracheostomy?
Not always; some transition to oral breathing as they grow, but it depends on anatomy and reconstruction plans. Hospital Civil de Culiacan
8) What reconstructions are possible?
Teams can create internal nasal airway, reconstruct the external nose, and advance the midface—usually in stages across childhood/adolescence. PubMed
9) Are outcomes good?
Case reports show many patients achieve stable breathing and meaningful cosmetic/functional improvements after staged reconstruction and therapy. PubMed
10) What about puberty?
Most need hormone induction (testosterone or estrogen/progesterone), with excellent bone and sexual-development outcomes when supervised. Nature
11) Can boys with undescended testes be helped?
Yes—urology can manage cryptorchidism surgically; endocrinology handles hormones and later fertility induction. Nature
12) Can women with BAMS conceive?
Fertility specialists can often assist with ovulation induction/IVF after endocrine optimization. Nature
13) Is smell/taste always absent?
Often reduced or absent because olfactory bulbs may be missing, but perception varies. PubMed
14) Does BAMS overlap with choanal atresia?
Yes; choanal atresia is reported in classic descriptions and influences airway decisions. Nature
15) Where should families get care?
At an experienced craniofacial center with ENT, plastics/maxillofacial, ophthalmology, endocrinology, anesthesia, genetics, speech/nutrition, and psychology. Hospital Civil de Culiacan
