The skull plays a very important role in the human body, not only in maintaining the integrity of the head’s shape, but also in protecting the intracranial tissues from damage. If there is a defect in the skull, there is no doubt that the patient’s image will be damaged and unattractive, in addition, it may also cause other problems, which are clinically referred to as “craniosynostosis syndrome”. Is craniosynostosis dangerous? Cranial defects are usually caused by traumatic injuries such as traffic accidents, production safety accidents, falling from height, etc. They can also be left behind after craniotomy due to intracranial tumors, cerebral hemorrhage, and other craniocerebral diseases. Is cranial defects harmful? After cranial defects, the integrity of the skull, the closure of the cranial cavity and the stability of the intracranial environment are damaged, leading to the obstacle of cerebrospinal fluid circulation and blood circulation, which affects the normal operation of neurological function and triggers some adverse symptoms. How is cranial repair surgery done? Cranial bone repair surgery is a very mature type of neurosurgery. Patients cannot undergo surgery immediately after cranial defects because this surgery has certain indications. Generally, 3 months after the debridement surgery, and the diameter of the defect is larger than 3CM, the aesthetic appearance as well as the normal life of the patient is greatly affected, can be considered for cranial bone repair surgery. The surgical operation is to incise the original incision along the edge of the defect and separate the scalp, flap, capitellum, and temporalis muscle. The area of the defect is exposed and a special medical material is placed over the defect, tightly sutured and then fixed, making the procedure relatively simple. How many cranial repair surgeries are performed nationwide? After learning about cranial repair surgery, patients next pay more attention to the repair hospital, then, how many hospitals in the country do cranial repair surgery. Cranial repair surgery can basically be carried out in local hospitals, but most of the titanium mesh material, this material is more likely to be rejected and infected after the operation, the titanium mesh may also be exposed, when these problems occur, the patient needs to replace the material, which means that the patients who choose titanium mesh repair may face the problem of secondary repair after the operation. The current clinical implementation of peek cranioplasty, the choice of peek material, this material is very good performance, effectively avoiding the problems of titanium mesh. The combination of the surgery with the plastic surgery concept results in an aesthetically pleasing symmetry between the two sides of the skull.
