Although the skull is hard, it is still difficult to resist some strong and powerful external impacts. Many people suffer from cranial defects due to accidents, which not only expose the brain tissue to external threats, but also affect the aesthetic image. Therefore, when suffering from skull defect, you need to go to a regular hospital and get a skull repair surgery to save your life. Cranial repair surgery is a relatively routine neurosurgical procedure that has become more and more sophisticated with the continuous development of medical technology. Likewise, the choice of skull repair materials is constantly changing in order to find safer and more suitable materials to achieve better post-operative recovery results. Titanium mesh is one of the repair materials generally chosen by hospitals, and it is quite advanced compared to traditional materials. However, titanium mesh has many limitations, and many patients are prone to rejection after surgery. What should I do if I experience rejection of titanium mesh during skull repair? It is a very unpromising phenomenon to have rejection reaction after skull repair surgery with titanium mesh material, which can only be removed through surgery, which is equivalent to the surgery for nothing. In fact, there is no need to worry anxiously after the rejection reaction of titanium mesh material, after taking out the titanium mesh material, you can choose more advanced and safer peek material for skull repair. The peek material is a very mature material, it is a combination of a variety of polymer compounds, strong stability, hard and elastic, thermal insulation is also very good, the scalp brain tissue will not produce stimulation and injury, after surgery will not occur rejection reaction, is the more ideal material choice for the current skull repair surgery, trustworthy.
