Treatment Options for Brachycephaly
Physical therapy and repositioning education should be the first-line treatment for mild to moderate brachycephaly, with cranial molding helmets reserved for moderate to severe cases or when repositioning fails to show improvement. 1
Diagnosis and Assessment
Before initiating treatment, proper diagnosis is essential:
- Clinical examination is typically sufficient for diagnosis of brachycephaly 1
- Imaging is rarely necessary except when clinical diagnosis is equivocal 1
- When needed, 3D cranial topographical imaging, skull x-rays, or ultrasound are preferred over CT scanning 1
- Brachycephaly is defined as flattening of the entire occipital region, resulting in a foreshortened head in the anterior-posterior dimension 1
- Quantitatively measured as a cranial index (CI = width divided by length × 100%) greater than 81% 2
Treatment Algorithm
First-Line Treatment: Repositioning and Physical Therapy
Repositioning education:
Physical therapy:
- Structured physical therapy program is superior to repositioning education alone 1
- Includes neck stretching exercises for any associated torticollis
- May include exercises to strengthen neck muscles
Second-Line Treatment: Cranial Orthotic Therapy (Helmet)
Consider when:
- Moderate to severe brachycephaly (CI ≥ 90%) 2
- Failed improvement with repositioning and physical therapy
- Infant is between 4-6 months of age (optimal starting time) 4
Effectiveness of Treatment Options
Repositioning and Physical Therapy
- Provides some degree of correction in virtually all infants with brachycephaly 1
- Less effective for severe brachycephaly (CI ≥ 90%) 2
- More effective when started early (before 4 months of age)
Cranial Orthotic Therapy (Helmet)
- More effective than repositioning for correcting severe brachycephaly 2
- Corrects asymmetry more rapidly and to a greater degree 1
- For severe cases (CI ≥ 90%), can reduce mean CI from 96.1% to 91.9% 2
- Long-term studies show greater improvement in head shape with helmet therapy compared to repositioning 5
- Earlier treatment initiation correlates with greater therapeutic effect 4
Important Considerations and Caveats
- Timing is critical: Earlier intervention (before 6 months) yields better outcomes for both methods 4
- Duration of therapy: Helmet therapy typically continues until 12 months of age or until correction plateaus
- Distinguish from craniosynostosis: True craniosynostosis (fusion of skull sutures) requires surgical intervention rather than conservative management 6
- Monitor for complications: Intracranial hypertension can occur in some cases of severe brachycephaly, particularly if associated with craniosynostosis 6
- Avoid positioning devices: The American Academy of Pediatrics warns against using soft positioning pillows in the sleeping environment due to SIDS risk 1
- Regular follow-up: Necessary to monitor progress and adjust treatment as needed
Predictors of Treatment Success
For helmet therapy, factors associated with better outcomes include 4:
- Male sex
- Moderate to severe degree of deformity at treatment initiation
- Larger head circumference at start of treatment
- Earlier treatment initiation
Remember that while brachycephaly is primarily a cosmetic concern in most cases, severe untreated cases can potentially affect facial symmetry and appearance, which may have psychosocial implications as the child grows.
