“…While this study provides valuable insights into the benefits of LeFort I advancement for patients with UCLP, several limitations must be acknowledged. A primary constraint is the limited sample size, as patients at our institution do not routinely receive pre- and postoperative standard CT scans [ 39 ]. Future studies with larger sample sizes and more diverse patient populations are essential for further validation of our findings.…”

“…The Institutional Review Board of the University of Texas Southwestern approved all CT scans that were used in the study. All scans were obtained for clinical purposes using a Siemens SOMATOM Definition CT scanner (Erlangen, Germany) following the Craniofacial-Flash protocol detailed in [ 39 ]. The Siemens SOMATOM Definition AS CT scanner is a third-generation helical, multislice unit.…”

Unilateral cleft lip and palate (UCLP) nasal deformity impacts airflow patterns and pressure distribution, leading to nasal breathing difficulties. This study aims to create an integrated approach using computer-aided design (CAD) and computational fluid dynamics (CFD) to simulate airway function and assess outcomes in nasal deformities associated with unilateral cleft lip and palate (UCLP) after LeFort I osteotomy advancement. Significant alterations were observed in nasal geometry, airflow velocity, pressure dynamics, volumetric flow rate, and nasal resistance postoperatively, indicating improved nasal airflow. The cross-sectional area increased by 26.6%, airflow rate by 6.53%, and nasal resistance decreased by 6.23%. The study offers quantitative insights into the functional impacts of such surgical interventions, contributing to a deeper understanding of UCLP nasal deformity treatment and providing objective metrics for assessing surgical outcome.

OBJECTIVEThere is an unmet need to perform imaging in young children and obtain CT-equivalent cranial bone images without subjecting the patients to radiation. In this study, the authors propose using a high-resolution fast low-angle shot golden-angle 3D stack-of-stars radial volumetric interpolated breath-hold examination (GA-VIBE) MRI sequence that is intrinsically robust to motion and has enhanced bone versus soft-tissue contrast.METHODSPatients younger than 11 years of age, who underwent clinical head CT scanning for craniosynostosis or other cranial malformations, were eligible for the study. 3D reconstructed images created from the GA-VIBE MRI sequence and the gold-standard CT scan were randomized and presented to 3 blinded reviewers. For all image sets, each reviewer noted the presence or absence of the 6 primary cranial sutures and recorded on 5-point Likert scales whether they recommended a second scan be performed.RESULTSEleven patients (median age 1.8 years) underwent MRI after clinical head CT scanning was performed. Five of the 11 patients were sedated. Three clinicians reviewed the images, and there were no cases, either with CT scans or MR images, in which a reviewer agreed a repeat scan was required for diagnosis or surgical planning. The reviewers reported clear imaging of the regions of interest on 99% of the CT reviews and 96% of the MRI reviews. With CT as the standard, the sensitivity and specificity of the GA-VIBE MRI sequence to detect suture closure were 97% and 96%, respectively (n = 198 sutures read).CONCLUSIONSThe 3D reconstructed images using the GA-VIBE sequence in comparison to the CT scans created clinically acceptable cranial images capable of detecting cranial sutures. Future directions include reducing the scan time, improving motion correction, and automating postprocessing for clinical utility.

Craniofacial Flash: Minimizing Radiation Dose in Pediatric Craniofacial Computed Tomography

Abstract: The Craniofacial-Flash protocol reliably generates craniofacial bone images adequate for routine use in craniofacial practice, while reducing the radiation dose by 88.87% compared with a conventional craniofacial CT scan, and eliminating the need for sedation.
