Craniosynostosis accounts for approximately 38% of cranial anomalies, and its clinical manifestations are mainly manifested by various different shapes of cranial deformities. The premature closure of the cranial suture restricts the growth of the skull and hinders the development of the brain, thus producing increased intracranial pressure. Patients may have protrusion of both eyes, downgaze, eye movement disorders, optic disc edema or secondary atrophy, visual impairment or blindness. Some patients may have mental retardation, and headache, nausea and vomiting may occur in the late stage. Some patients may have seizures due to cortical atrophy. The clinical manifestations of sialocraniosis can be divided into two categories: cranial deformities and secondary symptoms. The diagnosis can be made according to the particular head deformity, and attention needs to be paid to the developmental deformities of other parts of the body. On X-ray anteroposterior cranial radiographs, the medial wall of the orbit becomes oblique, the anterior cranial fossa becomes narrow, the bone density along the coronal suture increases, calcium deposits, and there are often cranial finger pressure cuts. On the lateral film, the frontal bone is posteriorly rotated, the bony prominence behind the frontal bone has no X-ray protrusion shadow performance, and the posterior cranial vault is normal. 2, navicular head deformity Cranial plain film can be seen in a navicular deformity, along the sagittal suture bone density, calcium deposits, serious cases can not see the bone suture, and coronal suture, herringbone suture, squamous suture widening, or even separation, such as intracranial pressure increase, can be seen in the cerebral gyrus pressure traces increased. 3.Triangular head deformity X-ray shows that the frontal bone is short and highly protruding, and the orbit is typically too short and the orbital wall is vertical in the orthopantomograph. 4.Oblique head deformity X-ray shows oblique head deformity, that is, the postorbital long axis is oblique upward and outward. The cranial image shows that at the coronal suture on that side, the bone density is increased and higher near the pterygoid point, and the anterior cranial fossa on the diseased side also becomes smaller and the base of the anterior cranial fossa becomes steeper. The nasal cone is skewed and the nasal crest is deviated to the lesioned side. 5.Short head deformity can be seen at both sides of the coronal suture bone density increased, skull base changes to shorten the anterior cranial fossa and erect, butterfly winglet high lift upward and backward skew, pterygoid point elevation and deepen the temporal fossa. The orbital volume becomes smaller.
