Premature closure of the cranial sutures, also known as cranial stenosis or stenocraniosynostosis, is a collective term for a group of disorders arising from premature closure of the cranial sutures in different parts of the skull, which interferes with the normal development of the skull and brain. The incidence in newborns is 0.25 per 1,000 births, with a predominance of male patients, and is especially common in premature closure of the sagittal or frontal sutures. How to check for premature closure of the cranial suture?1. Symptoms and signs of increased intracranial pressure. Such as headache, vomiting, vision loss and even blindness, optic papillae edema and even optic nerve atrophy.2. Mental confusion and mental retardation. The number of premature closure of cranial suture is directly related to the mental disorder. 3, hydrocephalus. Traffic hydrocephalus is common, and obstructive hydrocephalus can also be seen.4, visual impairment and eye protrusion. There can be monocular protrusion or binocular protrusion, and severe premature closure of cranial suture often has optic papillae edema and optic nerve atrophy.5, respiratory damage, posterior foramen atresia, snoring and sleep apnea, etc.6, premature closure of sagittal suture can appear navicular head; premature closure of coronal suture can appear short head deformity, and combined with other premature closure of cranial suture can appear pointed head deformity; premature closure of coronal suture and frontal pterionic suture can form frontal head obliquely deformity, premature closure of herringbone suture can form occipital head oblique deformity, and premature closure of coronal suture can form occipital head oblique deformity. Crouzon syndrome (craniofacial dysplasia), Apert syndrome (ACS type I, typical acromioclavicular syndactyly, acromioclavicular syndactyly type I), Vogot syndrome (ACS type II), and Apert syndrome (ACS type I, typical acromioclavicular syndactyly, acromioclavicular syndactyly type I). Syndrome (ACS Type II), Saethre-Chotzen Syndrome (ACS Type III), Warrdenbyrg Syndrome (ACS Type IV), Pfeiffer Syndrome (ACS Type V), Noack Syndrome (ACSP Type I), Carpenter Syndrome (ACSP Type II, pointed syndactyly and multiple finger/toe deformities) , Cohen syndrome (craniofacial-nasal dysplasia), and others. The efficacy of surgery is directly related to the severity of the deformity and the early or late stage of surgery: after decompression surgery, increased intracranial pressure, reduced vision and mental disorders can be improved to varying degrees. Neurosurgery should be performed as soon as possible, with cranial suture reconstruction or partial craniectomy and decompression.
