Sagittal synostosis: Quantitative assessment of presenting deformity and surgical results based on CT scans
Abstract
We reviewed our experience with nine consecutive patients with untreated isolated nonsyndromic sagittal synostosis. Using a method of 14 clinically relevant measurements taken from preoperative and postoperative CT scan images of these patients, we documented their presenting skeletal dysmorphology and the results of surgical correction at least 1 year after operation. Significant preoperative findings included an elongated cranial vault length that averaged 103 percent of normal and a narrowed cranial vault width both anteriorly at 92 percent and posteriorly at 86 percent of normal. Results of surgical correction, as documented by CT scan measurements, included normalization of the cranial length to 100 percent and of the anterior width to 101 percent of normal and improvement (but undercorrection) of the posterior width to 94 percent of normal. Quantitative measurement of CT scan images confirmed clinically observed findings in these patients before suture release and reconstruction and proved useful in assessing the surgical results achieved.

Intracranial volume in ISS can remain within normal limits in the first months of life despite the deformity and increases with age compared to normocephalic children.
“In fact, studies using CT scans to assess brain volume have shown that intracranial volume in ISS can remain within normal limits in the first months of life despite the deformity and that it increases with age compared to normocephalic children [17,18,19].”

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.
