انسداد الدروز القحفية: كيف يغيّر التخطيط ثلاثي الأبعاد الجراحة

Craniosynostosis affects roughly one in 2,000–2,500 live births. Untreated, it constrains skull and brain growth. Surgical correction releases the fused suture and restores normal cranial form during the window of rapid brain growth, usually within the first year.

Why freehand remodelling is difficult

Traditional vault remodelling is executed by eye against idealised templates. In an infant's thin, elastic calvarium, symmetry — especially in orbital bar advancement — depends heavily on experience, and operative times run long in patients with little physiological reserve.

The digital workflow

The infant's CT is segmented into individual bones and the deformity quantified against normative cranial indices. From the digital target, patient-specific osteotomy and positioning guides are produced — each keyed to unique anatomy so it seats in only one orientation. Published series report shorter anaesthesia times, reduced blood loss and improved symmetry versus freehand technique.

Paediatric considerations

• Timing: most vault remodelling between 6 and 12 months
• Low-dose CT protocols make planning imaging acceptable
• Paediatric cases get priority on the urgent pathway (3–5 days)
• Design package prepared for joint neurosurgery/craniofacial review
