Craniosynostosis, also known as early fusion of cranial sutures or cranial stenosis. Cranial suture reconstruction or craniectomy is performed. Post-operative periodical review and re-operation if necessary. The cause is unknown and may be related to fetal mesodermal developmental disorders, etc. It is a congenital malformation of the skull with membranous bone. It manifests as navicular head or long head deformity, oblique head deformity, pointed head or tower head deformity, etc. Surgery is usually performed from 6 months to 1 year of age after birth. Larger children with cranial hypertension should also be operated. Cranial suture reconstruction or craniectomy is performed to reconstruct new sutures so that the cranial cavity can expand with brain development to ensure normal brain development and correct the cranial deformity. Disease Description Craniosynostosis, also known as early fusion of cranial sutures or cranial stenosis. The manifestations include low intelligence, abnormal mental activity, and seizures. Surgery is usually performed between 6 months and 1 year after birth. Due to premature closure of the cranial suture, the cranial cavity is too small to accommodate normal brain development. Craniosynostosis, also known as cranial stenosis, premature closure of the cranial suture or ossification of the cranial suture, is a congenital malformation of the skull with membranous bone. Parents self-test whether their children have “craniosynostosis”: if they observe carefully, parents can find: 1. 2. Eye symptoms: shallow orbits, convexity of the eye, separated strabismus, etc. 3.Signs of restricted brain development and secondary intracranial pressure increase. The symptoms include low intelligence, abnormal mental activity and seizures. 4.It may be combined with other parts of the body deformities, such as syndactyly, cleft jaw, cleft lip, facial bone deformity, congenital heart disease, etc. 5.For suspicious cases, cranial X-ray or cranial CT should be taken to show that the jagged shape of fontanelle and cranial suture is not obvious or disappeared in the early stage, and finally the cranial suture is completely closed and the density is increased. There may also be cranial deformities and increased cerebral gyrus pressure traces. Once diagnosed, early surgery should be performed. Larger children with cranial hypertension should also be operated. Cranial suture reconstruction or craniectomy is performed to reconstruct the new suture so that the cranial cavity can be expanded with brain development to ensure normal brain development and to correct the cranial deformity. If most of the cranial sutures are closed prematurely and the brain is significantly compressed, surgery is needed in the first week after birth. It is also believed that the surgery should be performed at 6 to 12 months after birth, and those who have symptoms of cranial hypertension and vision loss after 1 year of age should still be operated. However, if the surgery is performed after 2 weeks of age, the results are not significant. The mortality rate of this operation is not high, only 0.39% has been reported, and the operation should be reviewed regularly and reoperated if necessary.
