“…Therefore, the CS is not likely to limit antero-posterior maxillary growth intrinsically, but it does limit anterior maxillary positioning. 10,16 Despite having significantly higher values in CS subjects, the SNB angle did not differ statistically between CS and control subjects. 19,20 Here, the cranial base is also associated with an increase in SNB angles as a result of shortening.…”

“…Totaling 352 cases and 1645 controls, the data came from several different studies. The smallest number of cases were reported byReitsma et al (2013), with 6, and the largest number of cases (80) were reported byLu et al (2021). In contrast to what Kobayashi et al (2020) found for Japanese CS patients, who have longer maxillary anteroposterior length, the most common change in CS patients was a decrease in maxillary and mandibular volume (anteroposterior length).…”

“…Angles SNA, SN/PP, and ANB were all significantly smaller in CS patients compared to those without CS, with the exception of the SNB angle. AlthoughCarinci et al (1994) found that CS patients have a larger orbital cavity volume,Lu et al (2021) found the inverse to be true.…”

Craniofacial characteristics in Crouzon's syndrome: A systematic review and meta-analysis

et al. 2023

The purpose of this meta-analysis was to strengthen the credibility of primary research results by combining open-source scientific material, namely a comparison of craniofacial features (Cfc) between Crouzon's syndrome (CS) patients and non-CS populations. All articles published up to October 7, 2021, were included in the search of PubMed, Google Scholar, Scopus, Medline, and Web of Science. The PRISMA guidelines were followed to conduct this study. PECO framework was applied in the following ways: Those who have CS are denoted by the letter P, those who have been diagnosed with CS via clinical or genetic means by the letter E, those who do not have CS by the letter C, and those who have a Cfc of CS by the letter O. Independent reviewers collected the data and ranked the publications based on their adherence to the Newcastle-Ottawa Quality Assessment Scale. A total of six case-control studies were reviewed for this meta-analysis. Due to the large variation in cephalometric measures, only those published in at least two previous studies were included. This analysis found that CS patients had a smaller skull and mandible volumes than those without CS.in terms of SNA° (MD = −2.33, p = <0.001, I2 = 83.6%) and ANB°(MD = −1.89, p = <0.005, I2 = 93.1%)), as well as ANS (MD = −1.87, p = 0.001, I2 = 96.5%)) and SN/PP (MD = −1.99, p = 0.036, I2 = 77.3%)). In comparison to the general population, people with CS tend to have shorter and flatter cranial bases, smaller orbital volumes, and cleft palates. They differ from the general population in having a shorter skull base and more V-shaped maxillary arches.

BackgroundThis study aims to compare the changes in ophthalmic parameters among syndromic craniosynostosis patients who underwent craniofacial skeletal expansion procedures via distraction osteogenesis (DO). MethodA retrospective study was conducted involving syndromic craniosynostosis patients who underwent surgical expansion via the DO technique from the year 2012 to March 2022. Changes in six parameters which consist of visual acuity, refractive error, optic disc health, intraocular pressure, degree of proptosis and orbital volume were measured objectively pre and post-surgery. For categorical parameters, the Chi-square cross-tab test was done. Paired sample T-test was used for normally distributed variables. Wilcoxon signed-rank test was used for non-normally distributed data. ResultsVisual impairment was present in 21.4% of eyes before surgery and increased to 28.5% post-surgery. Three patients had changes of refractive error postsurgery with one developed hypermetropia, another developed anisometropia and the last had improvement to no refractive error. Two patients had optic disc swelling which was resolved post-surgery. Intraocular pressure changes were inconsistent post-surgery. All patients achieved a signi cant reduction in the degree of proptosis post-surgery. Orbital volume calculation using computed tomography (CT) scans shows a signi cant increase in volume post-surgery for all patients. ConclusionOur study shows a signi cant increase in orbital volume post-surgery with a reduction in the degree of proptosis. Optic disc and nerve health improved after the surgery. Changes in terms of visual acuity, refractive error and IOP were inconsistent after the surgical intervention.
