Metopic Suture Release with Frontal Orbital Advancement
Surgical procedure involving release of the metopic suture and advancement of the frontal bone and orbital rims to correct the triangular forehead shape and expand the orbital volume.
Complete Cranial Vault Reconstruction
Comprehensive reconstruction of the anterior cranial vault using bone grafts and absorbable plates to achieve normal forehead contour. Reserved for severe cases with significant cosmetic and functional concerns.
Additional treatment options
Long-term Craniofacial Surveillance
Extended follow-up with craniofacial specialists to assess for recurrence of ridging, monitor cranial growth patterns, and evaluate for associated anomalies in syndromic cases.
monitoring3D Imaging and Surgical Planning
Advanced preoperative imaging using CT scanning and 3D reconstruction to precisely plan surgical approach, predict outcomes, and fabricate patient-specific implants or guides.
procedureEarly Intervention Developmental Therapy
Proactive speech, occupational, and physical therapy beginning in infancy to support developmental milestones and address any motor or cognitive delays associated with craniosynostosis.
