Apert syndrome is characterized by craniosynostosis, midface hypoplasia and symmetric syndactyly. A 36-year-old mother, G2P1 underwent an ultrasound scan at 19 week's gestation. There was craniosynostosis, brachi-turricephaly and bilateral hand syndactyly. Genomic DNA from amniocentesis revealed the mutation C758C>Gp. (Pro to Arg substitution) at 252 of the exon 8 of the FGFR2 encoding for Apert syndrome. The pregnancy was terminated. Femoral chondral plate histology showed an increased interstitial matrix between bony trabeculae. Compared with normal, the trabeculae were thinner, more irregular with numerous osteoclasts suggesting abnormal bone remodeling. Hands and feet had an abrupt transition between resting and proliferating cartilage. Apert syndrome has increased intertrabecular matrix, thin trabeculae, increased remodeling, and irregular transition between the maturing and mineralization zones in the femur, and abnormal abrupt transition between the resting and proliferating cartilage in the fingers and toes.

Objective: Prenatal detection of complex chromosomal rearrangements (CCR) is extremely rare, but is of great clinical importance, since CCR can be causative of different congenital disorders. We present an exceptionally rare case of prenatally diagnosed Saethre-Chotzen syndrome (SCS) rising as a consequence of chromothripsis involving chromosomes 5, 7 and 11 and deletion of TWIST1 gene.
Case Report: Brachycephaly, hypertelorism, flat face, micrognathia, relative macroglossia and small posterior fossa were noted on ultrasound examination at 28th gestational week.

External rigid distraction is an established method for achieving subcranial Le Fort III advancement in severe syndromic craniosynostosis. Craniofacial surgeons commonly use halo-type devices for these corrections, as they allow for multiple vectors of pull and facilitate larger midfacial advancements. Although most complications related to their use involve pin displacement or infection, rare complications such as skull fractures have been reported.

Objective: The exact association between the frequently present anomalous intracranial venous vasculature, emissary collaterals, ventriculomegaly, and increased intracranial pressure (ICP) in children with Apert and Crouzon syndromes remains an enigma. This study aimed to evaluate the association between the aberrant venous system and ventricle size and increased ICP, and to assess the development of the venous structures over time.
Methods: This retrospective cohort study included all patients with Apert or Crouzon syndrome with available CT venography (CTV) scans of the brain.
