Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Endoscopic Suturectomy
Minimally invasive surgical procedure to remove the prematurely fused suture, allowing the skull to expand naturally. This is typically performed in infants under 6 months of age when the bones are still flexible.
Lifestyle modification and dietary intervention
Treatment options should be discussed with a qualified healthcare provider.
Open Cranial Vault Remodeling
Traditional open surgery involving reshaping and repositioning of skull bones to correct the fused suture and restore normal head shape. May include frontal orbital advancement for more extensive corrections.
Additional treatment options
Helmet Therapy (Cranial Orthosis)
Custom-fitted helmet worn continuously to guide skull growth into a more normal shape following surgery. The helmet applies gentle pressure to areas needing containment while allowing expansion in desired directions.
procedureSerial Cranial Imaging
Regular CT or MRI scans combined with clinical examinations to monitor intracranial pressure, brain development, and the effectiveness of surgical interventions over time.
monitoringFamily Counseling and Support
