Background: The study aimed at assessing the variations in thickness of the supra-orbital bar in Crouzon (CS) and Apert syndromes (AS) before and after fronto-facial monobloc advancement (FFMBA) using CT-scan data. 87,88 Crouzon and Apert syndrome share many similar characteristics as noted earlier. Unable to display preview. The rarity of the Apert syndrome and similarity of features with other craniosynostosis syndromes like Crouzon, Pfieffer also makes it a diagnostic dilemma. In conclusion, Apert syndrome is more asymmetric in nature and a more severe clinical entity than Crouzon syndrome. Apert syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder.Nearly all cases of this condition result from new (de novo) mutations in the gene that occur during the formation of reproductive cells (eggs or sperm) in an affected individual's parent or in early embryonic development. Disturbances in the development of the branchial arches in fetal development create lasting and widespread effects. pp 91-95 | In both syndromes, clinical findings included concave profile, negative overjet, posterior crossbites, anterior openbite, and dental midline deviation, which were corrected in almost all cases with the final orthognathic surgery, with the exception of the lateral crossbites, including more than one tooth pair, which were persisting in about half of the cases. 2019 Mar 20;7(3):e2158.
