PURPOSE: The purpose of this study is to quantitatively establish the volumetric changes observed with posterior vault distraction osteogenesis in the anterior, middle, and posterior thirds of the cranial vault; characterize change in cranial length, width, and height, correlating these changes to demographic variables that may help identify why younger kids gain more volume; and describe the short-term position of the transport segment. METHODS: Multisuture craniosynostosis patients who underwent posterior vault distraction osteogenesis were retrospectively reviewed. Pediatric, dose-reduced, thin cut helically acquired head computed tomography scans were analyzed on Materialise Mimics v22 (Materialise, Ghent, Belgium). Pre and post-PVDO and "old" and "young" cohort were compared. RESULTS: Twenty-one patients met inclusion criteria. The change in cranial length was significantly less at a median of 14.9âmm [Interquartile range (IQR) 11.8, 31.6] compared to the X-ray measured AP distraction distance (30âmm [IQR 24, 33]; Pâ<â0.001) and significantly less than the theoretically calculated distance (23âmm [IQR 19, 31]; Pâ=â0.012). Median anterior cranial height was shorter post PVDO (82.9âmm, [IQR 64.8, 92.6] versus 78.7âmm [IQR 57.0, 88.7]; Pâ=â0.030). The younger cohort saw a greater increase in total intracranial volume (median 335.1âmL [IQR 163.2, 452.3, median 37.1%] versus 144.6âmL [IQR 119.0, 184.8, median 12.0%]; Pâ=â0.011). CONCLUSIONS: This is the first study to quantify volumetric changes to the anterior, middle, and posterior cranial vaults and demonstrates benefits of preforming PVDO at a younger age to help control turricephaly and produce greater percentage volumetric increases.
