Scaphocephaly part II: Secondary coronal synostosis after scaphocephalic surgical correction
Abstract
AIM: Occurrence of secondary coronal synostosis (SCS) and its functional consequences were retrospectively analyzed in sagittal synostosis. PATIENTS AND METHODS: Occurrence of SCS and/or fingerprinting and clinical signs of raised intracranial pressure were investigated in children with scaphocephaly with a minimum follow-up of 3 years. Children were divided in 4 groups according to surgery (group 1: "H" craniectomy [193 patients]; group 2: craniectomies with removal of the coronal sutures [24 children]; group 3:"H" craniectomies and flap transpositions without total removal of the coronal suture [36 patients]; and group 4: 253 nonsurgical patients with scaphocephaly). RESULTS: Among group 1, 20 (10.4%) developed SCS (3 mo to 6 y postoperatively). Fingerprinting was generalized in 13 patients, localized in 5, and absent in 2. Headaches were present in 8 patients. Papilledema appeared during follow-up in 2 of them. Intracranial pressure that was first recorded as normal became elevated, and they both required a surgical decompression. In group 2, none developed an SCS. In group 3, 11% developed SCS. In group 4, 1.2% nonsurgical patients with scaphocephaly presented with an SCS. However, group 4 corresponds to less severe morphologic deformation and/or parents refusing surgery. CONCLUSIONS: Secondary coronal synostosis appears to occur with an approximate 10% incidence after craniectomies not involving the coronal sutures, with 1% requiring surgical decompression. Patients with milder forms of scaphocephaly who were not operated on (1.2%) rarely developed an SCS. Long-term follow-up should be undertaken even in the milder forms for possible recurrence of secondary synostosis.

Postoperative synostosis of the coronal suture is the most common in this context and can occur in up to 10% of children after removal of the sagittal suture if both coronal sutures were not also removed at the time of surgery.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
