Craniofacial Fibrous Dysplasia (CFD)

Craniofacial fibrous dysplasia is a bone problem that happens in the skull and face. In this condition, normal hard bone is slowly replaced by soft, rubbery, fiber-like tissue. This fiber-like tissue then tries to become bone, but it does not become strong, mature bone. Because of this, the bone looks cloudy on scans, feels thicker or lumpy, and may grow in an uneven way. The change can make the face or skull look asymmetrical. It can press on nearby nerves, teeth, sinuses, the eye socket, or the ear canal. It often starts in childhood or the teenage years. It usually grows during growth spurts and then slows down in adulthood. Most people never develop cancer from it. This serious change is rare. CFD can affect one bone or many bones. It can occur by itself or as part of a syndrome called McCune–Albright syndrome, which also involves hormone problems and café-au-lait skin spots.

The main reason is a tiny change (mutation) in a gene called GNAS. This change happens after a baby starts to form (after conception), so it is not inherited from a parent. The change occurs in some cells but not all cells. This is called mosaicism. Cells with the change send “grow” signals too strongly. Bone-forming cells then make weak, immature bone mixed with fibrous tissue. Doctors sometimes describe the scan look as “ground-glass,” which means the bone looks hazy rather than clear.

Craniofacial fibrous dysplasia is a bone disorder where parts of the skull and face do not form normal, strong bone. Instead, the body replaces that bone with a mix of soft fibrous tissue and immature “woven” bone. This replacement bone can grow slowly and make the affected area thicker or misshapen. It may press on nearby nerves or spaces (like the sinuses, ear canal, or optic canal) and cause symptoms such as facial asymmetry, sinus blockage, hearing problems, or—rarely—vision problems. Most cases are benign (non-cancerous), and many people have mild disease with few symptoms. e-acfs.orgPMC

Types of Craniofacial Fibrous Dysplasia

Doctors group CFD in a few useful ways. Each type below tells you something practical about how it behaves or where it is.

1. By how many bones are involved

   • Monostotic CFD: only one skull or facial bone is involved (for example, only the maxilla or only the mandible).

   • Polyostotic CFD: two or more skull or facial bones are involved, or there are lesions in the face plus other bones in the body.

2. By association with a syndrome

   • Isolated CFD: bone changes happen without hormone problems or skin spots.

   • CFD in McCune–Albright syndrome (MAS): the same gene change affects bone and glands, so there can be early puberty, thyroid overactivity, growth-hormone excess, or café-au-lait patches.

   • CFD with Mazabraud syndrome: bone lesions with soft-tissue myxomas (benign soft lumps). This is less common.

3. By growth behavior (how active it looks clinically)

   • Quiescent (quiet): the lesion is stable in size and causes minimal symptoms.

   • Non-aggressive (slow): the lesion gradually enlarges and may change appearance slowly.

   • Aggressive (fast): the lesion grows faster, causes pain or nerve pressure, or deforms the bone more quickly.

4. By what it looks like on imaging

   • Ground-glass pattern: hazy, uniform look that is classic for fibrous dysplasia.

   • Mixed pattern: areas of hazy bone mixed with more dense bone and small cyst-like spaces.

   • Sclerotic pattern: more dense, whiter bone; sometimes seen in older or “burned-out” lesions.

5. By location in the face and skull

   • Maxilla (upper jaw) and zygoma (cheekbone): often give facial fullness or dental changes.

   • Mandible (lower jaw): may change bite or tooth position.

   • Frontal, sphenoid, ethmoid, temporal bones: may affect the sinuses, eye socket, optic canal, or ear canal.

   • Skull base: can sometimes touch important nerves and blood vessels.

6. By age pattern

   • Childhood-onset: tends to be more active during growth years.

   • Adult-onset or adult-recognized: often more stable with slower changes.

Causes

The proven root cause is one thing:

1. Post-zygotic activating mutation in the GNAS gene.
   This means a change in the GNAS gene happens after the embryo starts forming. It turns “grow” signals on too much in some bone-forming cells. It is not inherited and parents do not pass it on. These items are associations or modifiers. They can make the lesion more active, increase symptoms, or appear together with CFD because of the same gene change. I list them because patients often ask “what made mine worse?” or “why did it grow at that time?”

2. Timing of the mutation early in development.
   If the change happens very early, more tissues may carry it, so more bones can be involved.

3. How many cells in a bone carry the mutation (mutation load).
   A higher share of changed cells in one bone may lead to a bigger or more active lesion.

4. Growth spurts in childhood and adolescence.
   Natural hormones during these years can speed bone turnover, so lesions can grow faster.

5. Growth hormone excess (part of McCune–Albright syndrome).
   Too much growth hormone makes bone turnover high and can speed lesion growth.

6. Thyroid overactivity (hyperthyroidism in MAS).
   High thyroid hormone raises bone turnover and may worsen symptoms.

7. Early puberty or sex-hormone surges (in MAS or naturally).
   Hormonal swings can coincide with periods of faster lesion activity.

8. Phosphate wasting due to FGF23 (sometimes seen in fibrous dysplasia).
   Low phosphate weakens mineralization and can make bone pain and deformity worse.

9. Vitamin D deficiency and secondary hyperparathyroidism.
   Poor vitamin D makes bone weaker in general and may intensify symptoms.

10. High chewing or clenching forces on jaw bones.
    Strong bite forces can trigger pain or small stress changes in an involved mandible or maxilla.

11. Dental infections near the lesion.
    Infection does not cause CFD, but inflammation can swell tissue and worsen pain.

12. Chronic sinus inflammation near involved bones.
    Swollen sinuses can raise local pressure and make facial fullness and headaches worse.

13. Pregnancy-related hormonal shifts.
    Some people notice symptoms during pregnancy because hormones and blood flow change.

14. Untreated endocrine issues that travel with MAS.
    When thyroid or growth-hormone problems go untreated, bone activity can stay high.

15. General poor bone health (low calcium intake, inactivity).
    These do not create CFD, but they reduce reserve and may increase discomfort.

16. Smoking (weakens bone healing in general).
    Not a cause, but it is linked to poorer bone health and slower recovery after dental or jaw procedures.

17. Long-term high-dose steroids (weaken bone globally).
    Again, not a cause, but this can worsen overall bone quality and pain.

18. Local micro-trauma (repeated small stresses).
    Minor bumps or repetitive strain can increase soreness in an already involved area.

19. High local inflammatory signals (for example, IL-6) seen in research.
    These signals are part of how lesions remodel; higher levels may keep lesions active.

20. Lesion location at the skull base or near moving joints.
    Areas that naturally remodel more or move more can feel more symptomatic over time.

Common Symptoms and Signs

Not everyone has all symptoms. Many people have only mild changes. Symptoms often depend on which bone is involved and how active the lesion is.

1. Facial asymmetry or fullness.
   One side of the face can look bigger or rounder because the affected bone thickens.

2. A firm, painless bump over a bone.
   The skin over it is normal. The bump feels hard because it is bone.

3. Bone pain or tenderness.
   Pain may be dull and on-and-off. Pain often increases during growth spurts or with infection in nearby teeth or sinuses.

4. Headaches.
   Headaches can come from sinus pressure, nerve irritation, or muscle tension due to changed bone shape.

5. Dental crowding or teeth out of position.
   As the jaw bone expands, teeth may shift, crowd, or erupt late.

6. Bite changes (malocclusion).
   Upper and lower teeth may not meet well, making chewing uneven.

7. Toothache-like pain without a clear cavity.
   Pressure from the expanding bone can mimic dental pain.

8. Nasal blockage or chronic sinus stuffiness.
   If sinus walls thicken, airflow gets narrow and infections become more frequent.

9. Hearing problems or ear fullness.
   If the temporal bone or ear canal is involved, hearing may be reduced or feel blocked.

10. Ringing in the ears (tinnitus).
    This can happen with ear canal narrowing or pressure.

11. Vision changes or eye symptoms.
    There may be double vision, blurred vision, or eye bulging if the orbit or optic canal is affected. This needs prompt evaluation.

12. Numbness or tingling of the face.
    Pressure on sensory nerves can cause altered feeling in the cheek, lip, or jaw.

13. Jaw fatigue, clicking, or limited mouth opening.
    Changes near the jaw joint can make chewing tiring or noisy.

14. Sleep-disordered breathing or snoring.
    Airway narrowing from facial bone changes or enlarged turbinates can cause snoring or sleep apnea.

15. Emotional and social stress due to appearance.
    Changes in facial shape can affect confidence, mood, and social comfort. Support really helps.

Diagnostic Tests:

Doctors combine what they see, what you feel, your lab results, and your images to make the diagnosis and plan care. Below are the most common tests. I explain what each test is and why it helps.

A) Physical Examination

1. Head and face inspection.
   The doctor looks from the front, side, and top. They look for swelling, asymmetry, eye position, nose shape, and bite line. This simple look tells where the lesion might be.

2. Palpation of facial and skull bones.
   The doctor gently presses along the brow, cheekbone, jaws, and skull. They note firmness, borders, tenderness, and warmth. This helps tell if the lump is bone, soft tissue, or inflamed.

3. Cranial nerve screening at the bedside.
   The doctor checks vision, eye movements, facial feeling, facial movement, hearing, palate lift, and tongue movement. Any weakness or numbness may mean pressure on a nerve.

4. Oral and dental exam with bite check.
   The doctor or dentist checks gums, teeth, tooth percussion, and how upper and lower teeth meet. They look for crowding, bite shift, or tooth sensitivity.

B) Manual Bedside Tests

5. Jaw range-of-motion measurement.
   You open and close your mouth. The doctor measures the gap, tracks any deviation, and listens for clicks. Limited opening or deviation suggests joint or bone involvement.

6. Tuning-fork hearing tests (Rinne and Weber).
   These quick tests hint at ear canal or middle ear problems. A difference between ears can signal conductive or nerve-related hearing loss.

7. Vision screening (Snellen chart and color plates).
   Reading letters and recognizing colors detects early changes in the optic pathway. Trouble with sharpness or color can be an early warning.

8. Cover–uncover test for eye alignment.
   The doctor covers one eye and then the other to see if the eyes stay aligned. Misalignment can happen if the eye muscles or socket are pushed by bone.

C) Laboratory and Pathology Tests

9. Alkaline phosphatase (especially bone isoenzyme).
   This blood test rises when bone is very active. It does not prove CFD by itself but can reflect activity.

10. Calcium, phosphate, vitamin D, and parathyroid hormone (PTH).
    These tests look for low phosphate or low vitamin D, which can worsen bone pain and weakness. PTH shows how the body is balancing minerals.

11. IGF-1 and growth-hormone testing (with a suppression test if needed).
    If there is suspicion for growth-hormone excess, these tests check it. Treating hormone excess can calm lesion activity.

12. Thyroid function tests (TSH and free T4).
    These look for thyroid overactivity. Treating a high thyroid can reduce bone turnover.

13. Biopsy with histopathology, ± GNAS mutation testing.
    When imaging is not typical or surgery is planned, a small sample can be taken. Under the microscope, classic fibrous dysplasia shows immature woven bone (“Chinese-character” shapes) in a fibrous background. Specialized tests can detect the GNAS mutation, especially in tissue from the lesion.

D) Electrodiagnostic Tests

14. Visual evoked potentials (VEP).
    Small sensors check how fast signals move from the eye to the brain. If the optic nerve is under pressure, signals may slow.

15. Auditory brainstem response (ABR).This test measures how sound signals travel through the hearing nerve to the brainstem. It helps when hearing seems reduced but the ear exam is normal.

E) Imaging Tests

16. Panoramic dental X-ray (orthopantomogram/OPG).
    This single image shows the entire upper and lower jaws and tooth roots. It is a good screening test for jaw involvement and tooth position.

17. Maxillofacial CT scan with thin slices and 3-D views.
    This is the key imaging test. CT shows bone detail very clearly. It shows the “ground-glass” look, how thick the bone is, and how close it is to nerves, eye sockets, sinuses, and the ear canal. Surgeons use it to plan operations.

18. Cone-beam CT (CBCT) for dental and jaw detail.
    CBCT uses lower radiation than regular CT for the jaws and teeth. It is helpful for dentists and oral surgeons planning tooth, implant, or jaw work.

19. MRI of the face and skull base.
    MRI shows soft tissues, nerves, and blood vessels. It helps if doctors worry about nerve compression, eye muscles, or unusual soft-tissue changes. MRI complements CT rather than replaces it.

20. Bone scan (nuclear medicine scintigraphy).
    A small amount of tracer highlights areas of high bone turnover throughout the body. It helps map how many bones are involved, especially when doctors suspect polyostotic disease.

Non-pharmacological treatments (therapies & supportive care)

Below are proven or widely recommended non-drug steps. Each item explains the purpose and simple mechanism (how it helps).

1. Watchful waiting with scheduled follow-up
   Purpose: Avoid unnecessary procedures in mild, stable disease.
   Mechanism: Regular clinical exams and imaging catch any change early so action is taken only when truly needed. Evidence shows many CFD patients remain stable long-term. PLOS

2. Multidisciplinary care pathway
   Purpose: Coordinate decisions about timing of orthodontics, surgery, hearing/vision care, and endocrine screening.
   Mechanism: Shared planning reduces complications and prevents duplicated or conflicting interventions. BioMed Central

3. Education and self-monitoring
   Purpose: Help patients recognize red-flag symptoms (new pain, bite change, hearing drop, vision changes).
   Mechanism: Early reporting allows earlier, safer treatment. Patient guides and toolkits support this. fdmasalliance.org

4. Regular dental/periodontal care
   Purpose: Prevent cavities and infection around altered jawbone.
   Mechanism: Professional cleaning, fluoride, and good home care reduce infection risk that might complicate bone surgery. Guidelines note routine dental and orthodontic care is generally safe in FD/MAS. BioMed Central

5. Orthodontic planning (timed appropriately)
   Purpose: Improve function and esthetics when malocclusion occurs.
   Mechanism: Plan braces or aligners after healing from any jaw surgery and when disease is quiet; follow closely for stability. PMC

6. Occlusal splints or bite guards (case-by-case)
   Purpose: Reduce jaw muscle strain and protect dental work.
   Mechanism: Distributes bite forces more evenly on altered bone.

7. Hearing support (audiology)
   Purpose: Detect and treat conductive hearing loss from external auditory canal narrowing in temporal bone FD.
   Mechanism: Regular audiograms during growth; consider hearing aids or canal cleaning; surgery only for defined indications. PMCBioMed Central

8. Vision monitoring (neuro-ophthalmology)
   Purpose: Track optic nerve function if the optic canal is narrow.
   Mechanism: Visual acuity, color vision, fields, and sometimes VEP testing to catch early compression. Prophylactic decompression is not advised; surgery is considered only if vision is actually declining. PLOSSAGE Journals

9. Nasal/sinus care
   Purpose: Ease congestion or sinusitis if facial bones narrow sinus spaces.
   Mechanism: Saline irrigations, humidification, and ENT follow-up minimize infections; endoscopic surgery only if obstruction or recurrent infection persists (specialist-led). PMC

10. Airway and sleep care
    Purpose: Manage snoring or sleep-disordered breathing from midface/skull base narrowing.
    Mechanism: Sleep study; CPAP or corrective surgery if needed (team decision). PMC

11. Posture, neck, and jaw physiotherapy
    Purpose: Reduce muscle tension and headache around altered facial biomechanics.
    Mechanism: Gentle, supervised exercises improve muscle balance and joint comfort (adjunctive).

12. Pain self-management skills
    Purpose: Complement medical pain control.
    Mechanism: Heat/ice, relaxation, pacing, and cognitive strategies reduce pain amplification (adjunctive to analgesics). BioMed Central

13. Endocrine screening and treatment (FD/MAS)
    Purpose: Detect growth hormone (GH) excess, thyroid disease, phosphate problems, or early puberty in MAS.
    Mechanism: Treating GH excess early reduces craniofacial expansion and lowers risk of optic nerve troubles. PMC

14. Protective head and face gear during sports
    Purpose: Reduce fracture risk to affected bones.
    Mechanism: Shock absorption protects thinned or expanded bone.

15. Smoking cessation and alcohol moderation
    Purpose: Support bone and gum health and surgical healing.
    Mechanism: Smoking impairs blood flow; alcohol excess weakens bone over time.

16. Nutrition for bone health
    Purpose: Support normal bone metabolism and healing.
    Mechanism: Adequate calcium, vitamin D, protein, and micronutrients (details below in “What to eat”). (General support; does not “cure” FD.)

17. Psychosocial support and counseling
    Purpose: Address appearance changes, anxiety, and social stress.
    Mechanism: Counseling improves coping and treatment adherence.

18. 3-D imaging and surgical planning
    Purpose: Make surgery safer and more precise.
    Mechanism: Low-dose CT/3-D planning helps decide contouring vs resection and protects nerves. BioMed Central

19. Regular whole-skeleton survey when indicated
    Purpose: Map overall disease load and monitor change.
    Mechanism: Bone scintigraphy or ^18F-NaF PET/CT quantifies skeletal burden; this guides follow-up frequency and risk counseling. PMC

20. Avoidance of ionizing radiation to lesions
    Purpose: Minimize malignant risk.
    Mechanism: Radiation therapy is not recommended in FD; choose non-radiation alternatives where possible and use dose-optimized imaging. PMC

Drug treatments

Always prescribe and dose with a specialist. Doses below are typical adult starting points; pediatric dosing differs. Many uses here are “off-label.”

1. Acetaminophen (Paracetamol) – Analgesic
   Dose/Timing: 500–650 mg every 6–8 h PRN (max 3,000 mg/day unless doctor advises otherwise).
   Purpose: First-line for mild pain.
   Mechanism: Central pain modulation (non-anti-inflammatory).
   Side effects: Generally well tolerated; liver risk if overdosed or mixed with alcohol.

2. NSAIDs (e.g., Ibuprofen or Naproxen) – Anti-inflammatory analgesics
   Dose/Timing: Ibuprofen 200–400 mg every 6–8 h with food; or Naproxen 250–500 mg twice daily.
   Purpose: Bone and soft tissue pain with inflammatory component.
   Mechanism: COX inhibition reduces prostaglandins and pain.
   Side effects: Stomach irritation/ulcers, kidney strain, blood pressure rise; use stomach protection if at risk.

3. Gabapentin / Pregabalin – Neuropathic pain modulators
   Dose/Timing: Gabapentin 100–300 mg at night, then titrate; Pregabalin 50 mg twice daily then titrate.
   Purpose: Burning/nerve-type pain when nerves are irritated or compressed.
   Mechanism: Modulates calcium channels to calm overactive nerves.
   Side effects: Drowsiness, dizziness.

4. Short course Corticosteroids (specialist-guided)
   Dose/Timing: High-dose, short burst only for acute optic nerve or cranial nerve compression while arranging definitive care.
   Purpose: Temporarily reduce tissue swelling to protect vision/nerve function.
   Mechanism: Potent anti-inflammatory effect decreases edema around compressed nerves.
   Side effects: Mood changes, glucose rise, stomach irritation; not for long-term use. PubMedWebEye

5. IV Pamidronate – Bisphosphonate (bone resorption blocker)
   Dose/Timing: Common adult regimens include 60–90 mg IV per cycle, typically every 3–6 months; pediatric dosing is weight-based.
   Purpose: Reduce bone pain and turnover in active FD.
   Mechanism: Inhibits osteoclasts, lowering bone resorption and turnover.
   Side effects: Flu-like reaction after infusion, low calcium/phosphate, rare jaw osteonecrosis (dental check first). Evidence supports pain reduction; effects on function vary. PubMedBioMed Central

6. IV Zoledronic acid – Bisphosphonate
   Dose/Timing: Often 4–5 mg IV at long intervals (specialist-set; FD dosing may differ from osteoporosis).
   Purpose: Alternative when pamidronate fails or for convenience.
   Mechanism/Side effects: Like pamidronate; use dental precautions. Case series show benefit in some resistant cases. ScienceDirect

7. Oral Alendronate – Bisphosphonate
   Dose/Timing: 70 mg weekly (osteoporosis dosing); FD regimens vary and are specialist-guided.
   Purpose: Reduce turnover; RCT showed marker and BMD changes but not consistent pain benefit.
   Side effects: Esophageal irritation; jaw osteonecrosis risk is much lower than cancer-dosing IV regimens but still counsel. PMC

8. Denosumab (off-label; specialist-only) – RANKL inhibitor
   Dose/Timing: Regimens studied include 60 mg every 3 months; newer research explores moderate dosing.
   Purpose: For severe, refractory FD pain or lesion activity after bisphosphonates.
   Mechanism: Blocks osteoclast formation and activity.
   Cautions/Side effects: Rebound high calcium and rapid bone turnover on stopping; jaw osteonecrosis risk; must ensure vitamin D/calcium adequacy and have an exit plan. Emerging data show benefit but highlight safety concerns—this is tertiary-center therapy. Oxford Academic+1PMC

9. Topical intranasal steroids or short antibiotic courses (ENT-directed)
   Dose/Timing: As per ENT for symptomatic sinusitis/edema.
   Purpose: Reduce nasal/sinus inflammation when bony narrowing causes blockage.
   Mechanism: Local anti-inflammatory effect; antibiotics only for bacterial infections. PMC

10. Endocrine therapies for FD/MAS (when present)
    Examples: Somatostatin analogs or pegvisomant for growth hormone excess; antithyroid drugs or surgery for hyperthyroidism; targeted therapy for phosphate issues.
    Purpose: Control hormone overactivity that can worsen craniofacial disease and optic risk.
    Mechanism: Normalizing hormones reduces bone turnover and soft-tissue overgrowth. PMC

Not recommended: Routine radiotherapy; it is avoided in FD. PMC

Dietary “molecular” supplements

These do not treat FD itself. They support overall bone and gum health. Always check doses with your clinician, especially if you have kidney disease, calcium disorders, or are on antiresorptives.

1. Vitamin D3: 800–2,000 IU/day (adjust to blood levels). Supports calcium absorption and bone mineralization.

2. Calcium (diet first; supplement if needed): Aim ~1,000–1,200 mg/day total intake from food + supplements; split doses for absorption. Builds mineralized bone.

3. Magnesium (e.g., glycinate/citrate): 200–400 mg/day helps vitamin D activation and bone matrix enzymes.

4. Vitamin K2 (MK-7): 90–120 mcg/day helps carboxylate osteocalcin for proper mineral placement.

5. Omega-3 (EPA+DHA): ~1 g/day supports anti-inflammatory balance and periodontal health.

6. Collagen peptides: 5–10 g/day to support connective tissue matrix (adjunct to dental/periodontal care).

7. Silicon (orthosilicic acid): ~5–10 mg/day supports collagen cross-linking and bone matrix quality.

8. Zinc: 8–11 mg/day supports bone formation enzymes and wound healing.

9. Boron: 1–3 mg/day helps vitamin D/calcium metabolism.

10. Vitamin C: 200–500 mg/day supports collagen and gum/tissue healing.

(These are general bone-health supports; your team should individualize based on labs and medications.)

About “immunity boosters,” “regenerative” or “stem-cell drugs”

There are no approved immune-boosting, regenerative, or stem-cell medications for craniofacial fibrous dysplasia. Using unproven products can be risky and expensive. Research is ongoing into bone-remodeling pathways, but current medical therapy aims to control pain and bone turnover (for example, bisphosphonates or denosumab in selected cases) and to treat endocrine drivers when present. If someone offers “stem cell” injections or “regenerative drugs” for FD, seek a second opinion at an academic center. Safer, evidence-based alternatives are described above. BioMed CentralSAGE Journals

Surgical options

Surgery is personalized. The team chooses the least invasive approach that solves the problem and protects nerves.

1. Bony contouring (shaving/burring) for deformity
   Procedure: Sculpt the thickened bone to improve symmetry.
   Why: Improve appearance and relieve local pressure when lesions are stable.

2. Segmental resection with reconstruction
   Procedure: Remove a defined block of diseased bone and reconstruct with plates/grafts or free flaps when needed.
   Why: For severe deformity, instability, or when contouring alone will not last. BioMed Central

3. Endoscopic sinus surgery
   Procedure: Open narrowed sinus passages.
   Why: Recurrent sinus infections or blockage from FD-related narrowing; helps drainage and breathing. PMC

4. Temporal bone/ear canal surgery (e.g., canalplasty ± tympanomastoid surgery)
   Procedure: Remove bony narrowing, clean the canal, or address middle-ear issues.
   Why: Conductive hearing loss or canal cholesteatoma due to stenosis. JAMA NetworkSAGE Journals

5. Optic nerve decompression (only when vision is deteriorating)
   Procedure: Carefully unroof the optic canal to release pressure.
   Why: Therapeutic decompression is considered for documented visual decline; prophylactic decompression in people with normal vision is not recommended by consensus/meta-analysis. PLOSSAGE Journals

Prevent complications

1. Keep regular specialist follow-ups and imaging when advised.

2. Report any new pain, bite change, hearing drop, or vision symptoms at once.

3. Maintain excellent oral hygiene; treat dental issues early. BioMed Central

4. Complete audiology and ear checks if the temporal bone is involved. BioMed Central

5. Screen and treat endocrine problems (especially GH excess) promptly. PMC

6. Avoid head impacts; use protective gear in sports.

7. Stop smoking; moderate alcohol.

8. Optimize vitamin D and calcium under medical guidance.

9. Prefer non-radiation treatments where possible; avoid radiotherapy for FD. PMC

10. Use 3-D surgical planning in centers experienced with CFD when surgery is needed. BioMed Central

---

When to see a doctor urgently

• Any new or rapidly worsening vision symptoms: blurry vision, color desaturation, new field loss, or eye pain—especially if you know your optic canal is narrowed. NCBI

• Sudden or progressive hearing loss, ear blockage, or recurrent ear infections. PMC

• New bite changes, jaw pain, or dental infections not settling. BioMed Central

• Persistent or severe headaches, facial numbness/weakness, or new asymmetry.

• After any head trauma involving the affected area.

What to eat” and “what to avoid

Eat more of:

1. Calcium-rich foods (milk/curd, fortified plant milks, sesame, small fish with bones).

2. Vitamin D sources (oily fish, fortified foods; sunlight exposure per local advice).

3. Protein (eggs, pulses/beans, fish, lean meat) to support healing.

4. Magnesium sources (nuts, seeds, greens, legumes).

5. Vitamin K foods (leafy greens, fermented foods).

6. Omega-3s (fish, flax, walnuts).

7. Colorful fruits/vegetables (vitamin C and antioxidants).

8. Whole grains and pulses for steady energy.

9. Water—good hydration helps mucosa and general health.

10. Dental-friendly snacks (cheese, nuts, sugar-free yogurt) to protect gums/teeth.

Limit/avoid:

1. Sugary snacks and acidic sodas (tooth decay risk).

2. Excess salt (can increase calcium loss in urine).

3. Excess alcohol (hurts bone and gum healing).

4. Smoking (strongly avoid—healing/bone blood flow suffers).

5. Very high vitamin A from supplements (bone loss risk).

6. Crash diets that undercut protein/micronutrients.

7. Unsupervised herbal “bone cures” (unknown interactions).

8. Self-prescribed high-dose calcium/vitamin D without labs.

9. Hard/very sticky foods if jaw surgery is recent (follow surgeon’s diet).

10. Frequent snacking if you can’t brush soon—rinse and chew sugar-free gum instead.

FAQs

1. Is CFD cancer?
   No. It is a benign bone disorder. Cancerous change is rare; radiotherapy is avoided to keep risks low. PMC

2. Can the bone turn back to normal?
   Usually not. The goal is to keep you comfortable and functional, and to shape or remove bone only when needed.

3. Do all patients need surgery?
   No. Many do well with monitoring alone. Surgery is for specific problems like vision risk, airway blockage, hearing canal narrowing, or major deformity. PLOS

4. Will braces make it worse?
   Routine dental and orthodontic care is generally safe, timed thoughtfully and monitored closely. BioMed Central

5. What if the CT shows my optic canal is narrow but I see fine?
   You are monitored. Preventive (“prophylactic”) optic nerve decompression is not advised if vision is normal. PLOS

6. Can medicines shrink the lesion?
   Some medicines (like bisphosphonates or denosumab) can reduce bone turnover and pain; true “shrinkage” varies and evidence is still evolving. Specialist use only. PubMedPMC

7. Do I need special vitamins?
   You need healthy vitamin D, calcium, protein, and balanced micronutrients. Supplements support health but do not cure FD.

8. Are dental implants possible?
   Sometimes, in carefully selected, quiet lesions and with close follow-up; success is variable. A specialist team must decide. Iris Unito

9. Why screen for hormones?
   In FD/MAS, hormone overactivity (especially GH excess) can worsen craniofacial disease and optic risk. Treating it helps. PMC

10. Is pregnancy safe?
    Most people do well; plan with your team. Manage dental/ENT issues beforehand and maintain vitamin D/calcium as advised.

11. Will it spread?
    FD is not an infection or cancer, so it doesn’t “spread,” but existing lesions can enlarge during growth.

12. Can I play sports?
    Yes, with common-sense protection for contact sports and guidance if your jaw or skull is involved.

13. How often will I need scans?
    Depends on age, symptoms, and skeletal burden. Your team may re-image after changes or at defined intervals. PMC

14. Is radiotherapy ever used?
    No—current guidance advises against radiation in FD. PMC

15. Where should I be treated?
    Choose centers with experience in CFD/FD-MAS and a team that includes maxillofacial, ENT, ophthalmology, neurosurgery, dentistry/orthodontics, endocrinology, and radiology. BioMed Central
