Coronal and lambdoid suture evolution following total vault remodeling for scaphocephaly

OBJECTIVE Different types of surgical procedures are utilized to treat craniosynostosis. In most procedures, the fused suture is removed. There only a few reports on evolution sutures after correction To date, no published study describes neosuture formation total cranial vault remodeling. The objective this was understand bones in area coronal and lambdoid that were removed for complete remodeling patients with sagittal particular, investigation aimed confirm possibility formation. METHODS CT images skulls children who underwent operations scaphocephaly at Hôpital Femme Mère Enfant, Lyon University Hospital, Lyon, France, from 2004 2014 retrospectively reviewed. Inclusion criteria diagnosis isolated synostosis, age between 4 18 months surgery, availability reliable postoperative obtained minimum 1 year correction. Twenty-six boys 11 girls included, mean surgery 231.6 days (range 126–449 days). interval reconstruction scanning 5.3 years 1.1–12.2 years). RESULTS Despite removal both sutures, neosutures detected 3D reconstructions. All combinations seen: visible (n = 20); frontoparietal bony fusion 12); parietooccipital 3); 2). CONCLUSIONS This first report skull response normal patent following synostosis. reappearance rather common, but its incidence depends type suture. outcome differs these transverse sutures. might imply genetic functional differences among which still have be elucidated.
