Accidents always take us by surprise, and because of the sudden occurrence of accidents, they cause one kind of damage to our body, and cranial defects are one of the more common problems nowadays. Once a cranial defect occurs, the problem is quite serious, because the brain tissue loses the strong protection of the skull and can be affected by the outside world at any time. Cranial defect should be done in time for skull repair surgery so that the problem can be prevented from getting worse. An important factor that needs to be considered is the material to choose an ideal material in order to achieve better repair results. At present, many local hospitals widely use titanium plate material, which may be much more advanced than some previous materials, but there are some inevitable defects. In the end, how about titanium plate repair skull, the next to give you a detailed introduction. 1, the more common problem with titanium plate material is that patients may have infection after surgery, and titanium plate material can easily cause damage to the patient’s scalp tissue, and even lead to material exposure. 2, titanium plate material is a metal material, the thermal insulation of metal material is not very good, after receiving titanium plate material for skull repair surgery, it will make the patient easy to be sensitive to the external hot and cold environment, bringing a lot of discomfort. And the titanium plate material takes the way of covering repair during the surgery, the edge of the material is easy to cause cutting injury to the patient’s scalp tissue, the patient may produce obvious pain, and even cause scalp wear and material exposure. 3, there is another more important problem of using titanium plate material for skull repair surgery, titanium plate material will interfere with the transmission of radiation, which will affect CT and MRI examinations after surgery, leading to artifacts, affecting the results and interfering with the doctor’s diagnosis. From the above, we can see that the repair effect of titanium plate material is not ideal, and there are many side effects after surgery. For better skull repair surgery, it is recommended to use PEEK material. We use this new polyether ether ketone PEEK material with very good performance, which is basically comparable to autologous cranial bone, and it overcomes all the above problems very well. It has been well received by patients with cranial defects and their families.
