“…With regard to the OSA, the results were less obvious. These results were published in two separate articles from our group (Nout et al, 2012). Because of the development of an anterior open bite during DO, a malocclusion was observed in most patients (Fig.…”

“…The software program MevisLab Version 2.0 (Mevis Medical Solutions AG, Bremen) was used to import and analyze the CT scans by means of a custom-designed tool (Nout et al, 2012). Similar to the method that our group previously described, a coordinate system was created that allowed us to quantify the movement of structures independent of the position of the patient in the CT scan ( Fig.…”

“…The first method offers quick results, though frequently, they cannot be compared between different samples or between different clinicians due to the lack of standardized reproducible landmarks. Moreover, the procedure of volumetric measurement requires a manual delineation of a whole series of CT slices, a time consuming task, which results in data simply relating to volume change without any information in the direction [6,10].…”

Objectives The aim of this study was to create an evidence-based three-dimensional cephalometric analysis of orbits in order to perform time-efficient measurements of postoperative orbital morphology changes. Materials and MethodsThe authors used 23 (11 bilateral and 1 unilateral) anatomical landmarks. Based on these, 6 planes, 12 angular and 16 linear measurements were determined. A three dimensional analysis was performed twice by two observers on pre and post-operative computed tomography scans of six patients who had undergone midface advancement. The mean, minimal and maximal difference, as well as standard deviation (SD) and intraclass correlation coefficient (ICC) for the inter-and intraobserver landmark selection reliability were calculated.Additionally, the mean, minimal, maximal difference and standard deviation between pre-and post-operative angular and linear measurements were calculated to examine a connection between the established measurements and any morphological change. Results The inter and intra-examiner accuracy of all landmarks for three axes was [0.9 ICC. Despite excellent inter and intra-examiner agreement (\2.49 mm ± 2.05 mm SD) for the landmark selection, linear and angular measurements showed a mismatch, the mean SD for angular measurements was found to be 8.2°and the linear 3.04 mm. Discussion The possible causes of linear and angular measurement discrepancies are discussed and the future direction for the development of three-dimensional cephalometric analysis of orbits proposed.

“…At our institution, a follow-up CT is typically obtained at 1 year after surgery in order to evaluate for bone regeneration and the healing of bone gaps left behind from the surgery. Otherwise, imaging after craniosynostosis surgery may be performed at other times in order to assess for early and late surgical complications [3]. The various types of surgical procedures for treating craniosynostosis and the corresponding imaging findings are described and depicted in the following sections.…”

Several surgical options are available for treating the different types of craniosynostosis, including fronto-orbital advancement and remodeling, total or subtotal cranial vault remodeling, barrel stave osteotomy with cranial remodeling, endoscopic suturectomy, monobloc advancement and cranioplasty, and revision cranioplasty. High-resolution, low-dose CT with 3D reconstructed images and volumetric analysis can be useful for evaluating the craniofacial skeleton following surgery. The various types of craniosynostosis surgery and corresponding imaging findings are reviewed in this article.
