Cranial defect has long been not a rare problem, in neurosurgery for a variety of reasons resulting in cranial defect is very large number of patients, including a number of patients because of the occurrence of serious traumatic brain injury, and then have to undergo traumatic brain injury surgery and left behind a cranial defect. Cranial defects can cause various effects on the physical and mental health of patients, and it is necessary to pay attention to them. Will I get dizzy if I have a cranial defect from a traumatic brain injury? If the diameter of the skull defect exceeds 3cm, the patient will often experience dizziness, headache and other uncomfortable symptoms, and emotions will be easily agitated, and the defective part will also have obvious fluctuation. In addition, cranial defects will also directly affect the patient’s appearance, making the patient feel inferior and depressed. Therefore, no matter from what point of view, skull defects should be treated and remedied in a timely manner, and cranial repair surgery is a more effective way to rebuild a complete closed and stable cranial environment, which provides a certain degree of protection for all intracranial activities and the operation of the brain and nerve function. However, there is one thing that has to be reminded, the key to doing skull repair surgery also depends on the material and expert technology. Repair material is good after surgery recovery will be more ideal. At present, many hospitals are using titanium mesh material, which is an improvement over the earlier material, but there are still some unavoidable problems, such as a high chance of postoperative infection and rejection, which will affect the postoperative medical examination, and there is a risk of material exposure, etc. Obviously, titanium mesh material is not the best material for cranial bone repair. Obviously, titanium mesh material is not an ideal choice, and we are currently using a new type of polyether ether ketone peek material, which makes up for the defects and shortcomings of titanium mesh material, and all the properties are very close to the autologous cranium, and at the same time, we also continue to carry out technological innovation and improve the concept of cosmetic surgery, and comprehensively carry out peek cranial bone repair and plastic surgery, and the postoperative effect is very natural and beautiful.
