The cranium plays an important role in health, it is a defense wall to protect the brain as a commander-in-chief, but there are many risk factors in life that can cause cranial defects. Cranial defects are not fatal, but if they are not repaired in a timely manner, they can affect brain function to a certain extent and cause a series of cranial defect syndromes. In the clinic, many patients with skull defects may have dizziness and headache, the patient’s attention will be unfocused, the mood is unusually irritable, and the patient is also very insecure, afraid of collision again, which will be more dangerous. Therefore, it is recommended to go to the hospital for cranial defect surgery in time, so as to restore the closeness of the cranial cavity as soon as possible and reduce the damage. How long does it take to recover from cranial defect surgery? In fact, cranial bone repair surgery is not too big surgery in neurosurgery, the procedure is not very complicated and difficult, and the recovery period after surgery is not very long. However, there is a point that the postoperative recovery is good or bad and the length of time has a certain relationship with the patient’s physical conditions. In addition, patients should be careful when choosing the repair material, and a really good repair material can improve the success rate of the surgery. At present, in cranial bone repair, the more widely used is titanium mesh material, which is much more advanced than the traditional material in the past, but there are still many unavoidable problems, especially the postoperative complications are more, and the recovery effect is not ideal, such as postoperative infection and rejection, and even the risk of exposure of the material and so on. Titanium mesh material has disadvantages, and our team has adopted a new type of polyether ether ketone peek material, which can make up for the shortcomings of the titanium mesh material, and its various properties are very excellent, coupled with the continuous improvement and innovation in surgical technology, and the introduction of the concept of cosmetic plastic surgery, which makes the postoperative effect more natural and beautiful.
